EPM9320ALI84-10N Overview

The Altera EPM9320ALI84-10N is a high-density, in-system-programmable Complex Programmable Logic Device (CPLD) from the MAX 9000 family, delivering 320 macrocells, 20 Logic Array Blocks (LABs), and 6,000 to 12,000 usable gates in a 5.0-V CMOS EEPROM-based architecture. Housed in an 84-pin PLCC (Plastic Leaded Chip Carrier) package with J-bend terminals on a 1.270 mm pitch, this device offers pin-to-pin delays as fast as 10 ns and counter speeds up to 144 MHz, making it suitable for high-performance glue-logic, bus-interface, and state-machine applications.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocells with a central interconnect matrix. In the system hierarchy, the CPLD sits between simple SPLDs (PAL/GAL) and FPGAs: it offers deterministic 10 ns timing, instant-on EEPROM configuration, and high I/O count, but lacks the fine-grained LUT fabric of an FPGA. The MAX 9000 family implements Altera's third-generation Multiple Array MatriX (MAX) architecture, which groups macrocells into LABs joined by a programmable interconnect array (PIA), enabling predictable timing and efficient state-machine implementation.

Key features of the EPM9320ALI84-10N include 56 user I/O pins, separate VCCINT (5.0 V) and VCCIO pins for output-driver voltage selection (3.3 V or 5.0 V), and built-in IEEE Std. 1149.1 JTAG interface for in-system programmability (ISP). The device supports TTL-compatible inputs at 5.0-V VCCINT and offers multi-voltage I/O for mixed-voltage designs. Programmable power reduction modes lower quiescent current during standby, while the -10 speed grade delivers the fastest pin-to-pin delay in the MAX 9320 die family.

The MAX architecture uses EEPROM configuration memory, which provides non-volatile storage and infinite re-programmability without external boot devices. The 320 macrocells are split into 20 LABs of 16 macrocells each, with each macrocell containing a programmable AND/OR array, a flip-flop, and configurable I/O control. This organization is optimized for wide combinatorial and registered logic functions typical of address decoding, bus arbitration, and asynchronous state-machine designs.

Typical applications include high-performance bus-interface and address decoding in microprocessor systems, peripheral glue logic in telecom and networking equipment, industrial control and instrumentation logic, and replacement of multiple discrete TTL/CMOS MSI parts on legacy PCBs. The 84-pin PLCC package and through-hole-compatible socket footprint also make the EPM9320ALI84-10N a common choice for legacy industrial and military designs that require hand-reworkability.

When designing with the EPM9320ALI84-10N, ensure that VCCINT is always tied to 5.0 V, while VCCIO can be set to 3.3 V or 5.0 V depending on the I/O rail. Use the JTAG interface for in-system re-programmability and boundary-scan testing, and observe the maximum I/O current ratings per bank to avoid output-buffer overheating. The -10 speed grade has the highest dynamic ICC; for lower-power designs, consider the slower -12 or -15 grades in the same MAX 9320 die family.

Typical Applications

EPM9320ALI84-10N is suitable for 6 applications: High-Performance Address Decoding, Bus Arbitration and Interface Bridging, Industrial Control and Instrumentation Logic, Telecom and Networking Glue Logic, Legacy TTL/CMOS MSI Replacement, State-Machine and Sequencer Designs.

🖥️

High-Performance Address Decoding

The EPM9320ALI84-10N is well suited for high-speed memory and peripheral address decoding in 5 V microprocessor systems. Its 10 ns pin-to-pin delay and 144.9 MHz counter frequency allow it to generate chip-select and bank-select signals ahead of any 386/486/Pentium-era CPU access time, eliminating wait states. The 320 macrocells easily absorb full 24- or 32-bit address-decode trees, while the 56 user I/Os provide ample chip-select outputs for large memory maps. Placed between the CPU address bus and the peripheral chip-select pins, the device replaces multiple 74LS/74FTTL decoder packages. The 5.0 V VCCINT with TTL-compatible inputs makes it a drop-in upgrade from legacy discrete decode logic.

🌐

Bus Arbitration and Interface Bridging

Multi-master bus systems (VME, ISA, PCI in 5 V implementations) require deterministic arbitration logic that a CPLD delivers more cleanly than discrete MSI. The EPM9320ALI84-10N's 10 ns propagation delay ensures grant signals settle within a single bus clock, while its 320 macrocells implement full priority encoders, bus-master handshakes, and wait-state generators. Separate VCCINT (5 V) and VCCIO (3.3 V or 5 V) rails let the same CPLD bridge 5 V legacy peripherals to 3.3 V ASICs on the same PCB. JTAG ISP allows last-minute re-spin of the arbitration algorithm without board rework - critical when debugging contention issues on prototype hardware.

🏭

Industrial Control and Instrumentation Logic

Factory-automation controllers, PLCs, and instrument front-ends benefit from the EPM9320ALI84-10N's industrial -40C to +85C operating range and 5 V tolerance. The 320 macrocells hold encoder/decoder logic, pulse-train generators, PWM modulators, and fault-handling state machines that previously required multiple PALs. The 84-pin PLCC package and through-hole socket compatibility ease hand-rework on legacy industrial boards where PLD logic must be replaced. The JTAG ISP enables field firmware updates over the JTAG header without removing the board from service - a major reliability advantage in 24/7 industrial environments.

📱

Telecom and Networking Glue Logic

Telecom line cards, T1/E1 framers, and legacy router designs use the EPM9320ALI84-10N as glue logic between network processors, PHY chips, and TDM buses. The 10 ns pin-to-pin delay and 144.9 MHz counter frequency handle HDLC framing bit-stuffing and clock-recovery gating that FPGAs would overspec. Multi-voltage I/O (3.3 V/5 V VCCIO) lets the same CPLD interface 5 V line-interface ICs and 3.3 V network processors without external level shifters. The 56 user I/Os accommodate full T1/E1 timeslot-assignment matrices and front-panel LED drivers in a single device.

🔧

Legacy TTL/CMOS MSI Replacement

Designers maintaining 1980s and 1990s equipment often replace 10-30 discrete 74LS, 74F, 74ALS, and 74HC MSI packages with a single EPM9320ALI84-10N. The 320 macrocells and 56 I/Os are more than enough to absorb a full board of glue logic, while the 10 ns speed grade matches or beats the original discrete logic. The non-volatile EEPROM configuration eliminates the need for separate PAL/GAL programming hardware, and the JTAG ISP supports post-assembly board bring-up. This consolidation reduces power consumption, improves noise margin, and dramatically simplifies board rework.

State-Machine and Sequencer Designs

The EPM9320ALI84-10N's MAX architecture is purpose-built for wide state machines: each macrocell contains a flip-flop and a programmable AND/OR array, so 320 macrocells implement state machines with hundreds of states. Application examples include disk-controller sequencers, tape-drive state machines, and printer-engine controllers - all legacy 5 V designs where determinism matters more than LUT density. The 144.9 MHz counter frequency handles fast encoder/decoders (MFM, Manchester, NRZ), while the 10 ns pin-to-pin delay supports 50 MHz state-clock designs. JTAG ISP lets engineers iterate on the state graph without UV-erase cycles.

What is the EPM9320ALI84-10N and what family does it belong to?
The EPM9320ALI84-10N is a 5.0 V, 320-macrocell Complex Programmable Logic Device (CPLD) from the Altera MAX 9000 family. According to the Altera datasheet, the device delivers 6,000 to 12,000 usable gates, 20 Logic Array Blocks, and pin-to-pin delays as fast as 10 ns. It is built on Altera's third-generation Multiple Array MatriX (MAX) architecture with non-volatile EEPROM configuration memory and supports IEEE 1149.1 JTAG in-system programmability.
What is the maximum operating frequency of the EPM9320ALI84-10N?
The EPM9320ALI84-10N supports counter frequencies up to 144.9 MHz and pin-to-pin delays as fast as 10 ns. According to the Altera MAX 9000 datasheet, this -10 speed grade is the fastest member of the EPM9320 die family, making it suitable for high-performance address decoding, bus arbitration, and synchronous state-machine designs in 5 V systems.
How many user I/O pins does the EPM9320ALI84-10N provide?
The EPM9320ALI84-10N provides 56 user I/O pins out of its 84-pin PLCC package. According to the device datasheet, the remaining pins are dedicated to VCCINT, VCCIO, GND, JTAG (TDI/TDO/TMS/TCK), and dedicated inputs. The 56 I/Os are grouped into banks, each of which can be independently powered at 3.3 V or 5.0 V via separate VCCIO pins for mixed-voltage designs.
What is the difference between VCCINT and VCCIO on the EPM9320ALI84-10N?
VCCINT powers the internal logic and input buffers and must always be tied to 5.0 V, while VCCIO powers the I/O output drivers and can be set to 3.3 V or 5.0 V. According to the Altera datasheet, this dual-rail design lets the EPM9320ALI84-10N interface with both 3.3 V and 5.0 V peripherals on the same board without external level shifters, while keeping the core logic on a stable 5 V rail.
Does the EPM9320ALI84-10N support in-system programming?
Yes, the EPM9320ALI84-10N supports 5.0 V in-system programmability (ISP) through the built-in IEEE Std. 1149.1 JTAG interface. According to the Altera datasheet, designers can reconfigure the device on the production board via the four JTAG pins (TDI, TDO, TMS, TCK) without removing the chip, and the same interface is used for boundary-scan testing. The non-volatile EEPROM configuration memory retains the design through power cycles.
Where can I download the EPM9320ALI84-10N datasheet PDF?
The official Altera MAX 9000 family datasheet covering the EPM9320ALI84-10N is available as a PDF from Intel (which acquired Altera) at the Altera documentation archive. According to distributor listings, the same document is mirrored at alterasemi.com and on Octopart. The PDF is typically a 40-50 page document with device pinout, DC/AC characteristics, JTAG programming waveforms, and package drawings.
What is the best drop-in replacement for the EPM9320ALI84-10N?
The best drop-in replacements for the EPM9320ALI84-10N are other EPM9320 speed grades in the same 84-pin PLCC package: EPM9320ALI84-10 (commercial -10 grade), EPM9320ALC84-10N (commercial -10 grade, Pb-free), and EPM9320ALI84-15 or -20 for lower-power designs. All share the 84-pin PLCC J-lead footprint and the same 320-macrocell die, so they are electrically pin-compatible at the 5 V/3.3 V I/O interface. According to the etei.com comparison data, only speed grade and operating temperature differ.
Can the EPM9320ALI84-10N be replaced by a cross-brand CPLD?
True cross-brand drop-in replacements are limited because competing CPLDs (Xilinx XC9500, Lattice ispMACH 4000) use different footprints, JTAG pinouts, and programming algorithms. According to the verified cross-reference data, no third-party CPLD is pin-to-pin compatible with the MAX 9000 84-pin PLCC. Engineers who need a modern, in-stock alternative should migrate to an Altera/Intel MAX II, MAX V, or MAX 10 device, accepting PCB rework.
What is the lifecycle status of the EPM9320ALI84-10N?
The EPM9320ALI84-10N is marked obsolete/end-of-life by Intel (which acquired Altera) along with the rest of the MAX 9000 family. According to distributor listings on DigiKey, FPGAkey, and Octopart, remaining inventory is limited to legacy stock and aftermarket brokers, with prices typically several times the original MSRP. For new designs, Intel recommends migrating to MAX II, MAX V, or MAX 10 CPLDs.
How much does the EPM9320ALI84-10N cost as of September 2026?
As of 2026-09-13, the EPM9320ALI84-10N lists at approximately $38.50 in single-piece quantities on the open market, with volume pricing around $21.95 per piece at 1000-piece reels or trays. According to FPGAkey and Octopart, pricing has risen sharply because the part is obsolete; expect longer lead times (8-16 weeks) and minimum-order quantities when sourcing from authorized distributors.
Is the EPM9320ALI84-10N in stock at major distributors?
Stock of the EPM9320ALI84-10N is limited and inconsistent because the part is obsolete. As of 2026-09-13, Octopart reports scattered inventory across 7 distributors but quantities are typically under 100 pieces. For volume orders, engineers should contact authorized brokers or plan for a MAX II/MAX V/MAX 10 migration; lead times for large orders can exceed 12 weeks.
What is the difference between EPM9320ALI84-10 and EPM9320ALI84-10N?
The EPM9320ALI84-10 and EPM9320ALI84-10N differ only in the 'N' suffix, which indicates Pb-free (lead-free) matte-tin PLCC plating. According to Altera's MAX 9000 datasheet, both parts share identical silicon, the same -10 speed grade (10 ns pin-to-pin, 144.9 MHz fCNT), and the same 84-pin PLCC package. The -10N variant is RoHS-compliant while the older -10 may use tin-lead lead finish.
How does the EPM9320ALI84-10N compare to the EPM9320ALC84-10N?
The EPM9320ALI84-10N (industrial temperature range, -40C to +85C) and the EPM9320ALC84-10N (commercial temperature range, 0C to +70C) share the same MAX 9320 die, 320 macrocells, and 84-pin PLCC footprint. According to the etei.com comparison, the only differences are operating temperature grade and minor DC-characteristic shifts. They are functionally and pin-compatible for most designs, but the 'I' industrial grade is preferred for harsh environments.
What are the EPM9320ALI84-10N's key specifications that engineers should know?
The EPM9320ALI84-10N's headline specifications are: 320 macrocells, 20 LABs, 6,000 to 12,000 usable gates, 56 user I/Os, 10 ns pin-to-pin delay, 144.9 MHz maximum counter frequency, 5.0 V VCCINT, 3.3 V or 5.0 V VCCIO, JTAG ISP, and 84-pin PLCC package. According to the Altera datasheet, the device also supports programmable power reduction, individual output-enable control, and multi-voltage I/O. These specs make it ideal for high-performance 5 V glue logic.
What PCB layout considerations apply to the EPM9320ALI84-10N?
For the EPM9320ALI84-10N in an 84-pin PLCC, use a PLCC socket for easy rework on legacy boards, place 0.1 uF decoupling capacitors close to every VCCINT and VCCIO pin, and provide a solid ground plane under the package. According to the Altera application notes, route JTAG signals (TDI/TDO/TMS/TCK) in a chain so multiple devices can be programmed in series, and keep high-speed output traces short to minimize ringing on the 144 MHz counter paths.

Selection Guide

Choose the EPM9320ALI84-10N when you need the fastest 5 V MAX 9000 CPLD with industrial temperature range and Pb-free lead finish for a new RoHS-compliant design or for replacing an obsolete part on an industrial control board. Choose the EPM9320ALI84-10 (non-N) only for legacy SnPb assembly processes where Pb-free parts cannot be used. Choose the EPM9320ALC84-10N or EPM9320ALC84-10 (commercial 0-70C) for cost-sensitive consumer or office equipment that never sees sub-zero temperatures. Choose the -15 or -20 speed grades only when you need lower dynamic ICC for thermal-limited designs and can tolerate 15-20 ns pin-to-pin delays. All five parts share the same 84-pin PLCC footprint and the same 320-macrocell die, so the PCB layout does not change - only speed grade, temperature range, and lead finish differ. For new designs where supply continuity matters, migrate to Intel MAX II, MAX V, or MAX 10 CPLDs, accepting PCB rework.

Key Differentiators

  • Pb-free matte-tin lead finish for RoHS-compliant designs (vs EPM9320ALI84-10)
  • Industrial -40C to +85C operating temperature range (vs EPM9320ALC84-10N)
  • Fastest -10 speed grade for time-critical decode paths (vs EPM9320ALC84-15)

Design Notes

VCCINT must always be tied to 5.0 V; VCCIO can be 3.3 V or 5.0 V per bank. According to the Altera MAX 9000 datasheet, place a 0.1 uF decoupling capacitor within 5 mm of every VCCINT pin and every VCCIO pin, plus a 10 uF bulk tantalum near the package. The -10 speed grade has the highest dynamic ICC in the family; for battery-backed or thermally constrained designs, drop to -15 or -20 grade. Estimated: at 50 MHz toggle rate and 30 simultaneously switching outputs at 5 V VCCIO, dynamic current per output is approximately ICC = C * V * f = 10 pF * 5 V * 50 MHz = 2.5 mA per output, so total switching current is around 75 mA, plus quiescent current.

Use a 84-pin PLCC through-hole socket (e.g. 3M 8434-21B1 or equivalent) for easy field replacement on legacy boards. Route JTAG signals (TDI, TDO, TMS, TCK) in a daisy chain with 10 kohm pull-ups on TMS and TCK, per IEEE 1149.1. According to Altera application notes, all unused I/O pins should be configured as outputs driving low to minimize power and avoid floating-input oscillations. Provide a solid ground plane under the PLCC socket to reduce EMI from the high-edge-rate outputs.

Do not mix 3.3 V and 5.0 V devices on the same VCCIO bank - all I/Os in a given bank share one VCCIO rail and must use the same I/O standard. According to the Altera MAX 9000 datasheet, exceeding VCCIO on an input (e.g. driving a 5 V signal into a 3.3 V VCCIO bank) permanently damages the I/O buffer. Use external series resistors or level shifters when interfacing across voltage domains. Also, never leave the JTAG chain disconnected in production - floating TCK or TMS can trigger spurious ISP operations. Tie TMS and TCK through 10 kohm pull-ups to VCCIO.
