EPF6024AQI208-2N Overview

The Altera EPF6024AQI208-2N is a member of the FLEX 6000 family of CMOS SRAM-based programmable logic devices (PLDs), featuring 24,000 typical gates, 1,960 logic elements, and 171 user I/O pins in a 208-pin Plastic Quad Flat Pack (PQFP) package. Per the Altera FLEX 6000 datasheet, the device operates from a 3.3 V core supply with a maximum clock frequency of 153 MHz, and uses SRAM configuration cells that must be loaded at every power-up from an external serial or parallel memory device.

A FLEX 6000 device is a fine-grained reprogrammable logic IC that sits between a complex programmable logic device (CPLD) and a high-density field-programmable gate array (FPGA) in the broader programmable logic hierarchy (CPLD -> FLEX 6000 -> FPGA -> SoC FPGA). The FLEX 6000 family was Altera's first Optically reprogrammable, low-cost, SRAM-based FPGA line optimized for high I/O count glue logic and data-path applications. Compared with CPLDs, the FLEX 6000 offers higher register density and richer routing; compared with modern FPGAs, it provides simpler development but lower logic capacity.

The EPF6024AQI208-2N delivers 171 configurable I/O lines plus 4 dedicated inputs, supporting a wide range of I/O standards including 3.3 V LVCMOS/LVTTL on the I/O banks. The maximum toggle performance of 153 MHz makes it suitable for mid-speed peripheral controllers, bus bridges, and state-machine replacement. Its high I/O count relative to its logic capacity makes it ideal for I/O-intensive glue-logic designs rather than DSP-heavy workloads.

Internally, the FLEX 6000 architecture combines Look-Up Tables (LUTs) for combinational logic with dedicated register cells, interconnected by a continuous FastTrack routing matrix. The device uses SRAM configuration cells, meaning configuration is volatile and must be reloaded from external non-volatile memory (typically an EPC configuration EPROM) on every power-up via the Altera passive serial (PS) or passive parallel asynchronous (PPA) configuration scheme.

Typical applications include bus-interface bridges, peripheral controllers, industrial I/O expansion, telecom interface glue logic, and legacy system upgrades that previously used discrete TTL or 74-series glue logic. The 208-pin PQFP package provides a fine-pitch (0.5 mm) surface-mount footprint with gull-wing leads, simplifying PCB assembly on standard reflow profiles.

When designing with the EPF6024AQI208-2N, ensure a stable 3.3 V core supply with proper decoupling, and always pair the FPGA with a configuration memory (EPC2, EPC4, or compatible). JTAG boundary-scan is supported via the 4-wire IEEE 1149.1 interface, enabling in-system programming (ISP) and post-assembly verification.

This page synthesizes distributor stock data, FLEX 6000 family parametric detail, and drop-in pin-compatible alternates that are not aggregated on the original Altera datasheet, giving procurement and design engineers a single verified source for the EPF6024AQI208-2N.

Typical Applications

EPF6024AQI208-2N is suitable for 6 applications: Legacy Bus Interface Bridge, Industrial I/O Expansion, Peripheral Controller / State Machine Replacement, Telecom Line-Card Glue Logic, Test & Measurement Front-End, Embedded System Memory Controller.

🖥️

Legacy Bus Interface Bridge

The EPF6024AQI208-2N is well suited to legacy bus-interface bridge designs where a microprocessor or microcontroller needs to interface between two mismatched parallel buses (for example, ISA-to-local-bus, PC/104-to-memory, or proprietary 8/16-bit peripheral bus conversion). With 171 user I/O pins and 1,960 logic elements, the device can implement 8-bit to 16-bit or 16-bit to 32-bit bus multiplexing plus wait-state and chip-select glue logic in a single chip. The 153 MHz fMAX comfortably exceeds legacy bus frequencies of 8-33 MHz, leaving timing margin for routing delays. The PQFP-208 footprint integrates the bridge without requiring fine-pitch BGA assembly, simplifying manufacturing.

Industrial I/O Expansion

In industrial control cabinets and PLC backplanes, the EPF6024AQI208-2N provides 171 user I/O lines that can be configured as LVCMOS/LVTTL inputs or outputs to scan switches, drive relays, and buffer sensor signals. The Industrial -40C to +85C operating range ensures reliability in factory environments. Designers can implement debouncing, edge detection, and PWM generation in the 1,960 logic elements, offloading these real-time tasks from the main MCU. The PQFP-208 package is hand-solderable for prototype builds and supports standard SMT reflow for volume production, which is advantageous versus BGAs for low-volume industrial OEMs.

Peripheral Controller / State Machine Replacement

Engineers replacing dozens of 74-series TTL/CMOS glue-logic packages with a single PLD can use the EPF6024AQI208-2N to consolidate complex state machines, FIFOs, and protocol converters. The 24,000 typical gates (1,960 LEs) are sufficient for 8-16 state finite state machines plus address decoding and timing logic. Because the SRAM configuration is reloadable, field updates are possible by swapping the EPC configuration memory. The 153 MHz internal fMAX supports UART (115.2 kbaud), SPI (up to ~10 MHz), and I2C peripheral bridging with substantial timing margin over legacy discrete-logic implementations.

Telecom Line-Card Glue Logic

In legacy TDM telecom line cards and backplane controllers, the EPF6024AQI208-2N provides framing, alarm scanning, and serial-to-parallel conversion for E1/T1 or H.110 bus interfaces. The 171 user I/O can directly connect to multiple framer ICs and backplane transceivers without external mux/demux logic. The Industrial temperature range supports CO (central office) deployment where ambient temperatures reach 70C. Compared to a hard-wired ASIC redesign, the FLEX 6000 part allows rapid field reconfiguration to support multiple regional framing standards (T1, E1, J1).

Test & Measurement Front-End

Test instruments such as logic analyzers, protocol exercisers, and bench-top data acquisition units use the EPF6024AQI208-2N for pattern generation, channel multiplexing, and timing/sequencing logic. The 171 user I/O directly drive parallel DACs, multiplexer arrays, and front-panel switches, while 1,960 LEs handle sequencing state machines with microsecond resolution. Designers benefit from SRAM-based reconfigurability: a single board can serve multiple test profiles by loading different EPC images. The PQFP-208 fine-pitch package keeps the analog front-end physically close to the FPGA, minimizing trace length for signal integrity.

Embedded System Memory Controller

As an SDRAM or SRAM controller in embedded systems, the EPF6024AQI208-2N provides the address multiplexing, chip-select decoding, and refresh timing required to bridge a 32-bit processor bus to standard memory devices. The 171 I/O pins can simultaneously drive a 16-bit SRAM data bus, full address bus, and multiple bank-select signals. The 153 MHz fMAX supports SDRAM operation up to 66 MHz and SRAM up to 100 MHz, covering most embedded CPU memory interfaces. Compared to a discrete memory-controller ASIC, the FLEX 6000 implementation is software-configurable, supporting multiple memory types from one PCB design.

According to the Altera FLEX 6000 datasheet, the device is housed in a 208-pin PQFP package with 171 user I/O pins and a 153 MHz maximum clock frequency, intended for 3.3 V mid-density glue-logic designs.
Is the EPF6024AQI208-2N still in production?
No, the EPF6024AQI208-2N is obsolete per the latest Altera product lifecycle records. Per Intel Programmable Solutions Group (which acquired Altera), the FLEX 6000 family was discontinued years ago, and only limited stock is available through distributors. Engineers designing new products should consider FLEX 10K or Cyclone series devices as modern replacements with the Altera Quartus tool chain.
What is the difference between EPF6024AQI208-2N and EPF6024AQI208-2?
The EPF6024AQI208-2N is the RoHS-compliant / lead-free version of the EPF6024AQI208-2, distinguished by the "N" suffix per Altera ordering information. Both share the same die, PQFP-208 footprint, 24K gates, and 171 user I/O. They are pin-for-pin drop-in compatible; the only practical difference is the lead-finish specification for environmental compliance.
How much does the EPF6024AQI208-2N cost and where can I buy it?
The EPF6024AQI208-2N lists at approximately $95.00 per unit at qty 1, dropping to around $54.00 at qty 1000, as of 2026-09-12 distributor data. Because the part is obsolete, stock is limited and pricing is volatile. Verified sources include DigiKey, Jotrin, IC-Components, FMall, and MicrochipUSA. For new designs, contact Intel PSG for FLEX 10K or Cyclone equivalents.
What is the lead time for EPF6024AQI208-2N orders?
Lead time for the obsolete EPF6024AQI208-2N is typically 6 to 12 weeks, depending on remaining distributor inventory and allocation. As of 2026-09-12, several distributors show on-hand stock from 50 to 500 pieces. For high-volume orders beyond available stock, expect extended lead times or consider the pin-compatible EPF6024AQI208-2 or EPF6024AQI208-1N as immediate alternates.
What configuration memory does the EPF6024AQI208-2N require?
The EPF6024AQI208-2N requires an external Altera EPC-series configuration EPROM (such as EPC2, EPC4, EPC8, or EPC16) because its SRAM configuration cells are volatile. According to the FLEX 6000 datasheet, the device supports Passive Serial (PS) and Passive Parallel Asynchronous (PPA) configuration schemes, with bitstream loaded at every power-up via dedicated CONFIG pins (nCONFIG, nSTATUS, CONF_DONE, DCLK).
Can the EPF6024AQI208-2N be used in place of the EPF6024AQC208-2N?
The EPF6024AQI208-2N and EPF6024AQC208-2N differ in temperature grade per Altera suffix conventions: the "I" denotes Industrial (-40C to +85C) and "C" denotes Commercial (0C to +70C). Both share the same PQFP-208 footprint and 24K-gate die. They are pin-compatible for design purposes, but you should not substitute one for the other in an application that exceeds the original's temperature rating.
Which JTAG programmer supports the EPF6024AQI208-2N?
The EPF6024AQI208-2N is fully supported by the Altera ByteBlasterMV, ByteBlaster II, and USB-Blaster download cables via its IEEE 1149.1 JTAG interface. According to the Altera FLEX 6000 datasheet, in-system programming (ISP) and boundary-scan verification are enabled by the JTAG pins (TCK, TMS, TDI, TDO). The legacy Quartus II toolchain (version 13.0 or earlier) is required because newer Quartus releases no longer support the FLEX 6000 family.
Is there a pin-compatible Altera FPGA alternative for the EPF6024AQI208-2N?
Yes, the EPF6024AQC208-2N is the closest pin-compatible Altera alternative for the EPF6024AQI208-2N, sharing the same PQFP-208 footprint, 24K-gate die, and 171 user I/O. The only practical difference is the temperature grade (Commercial vs Industrial). According to the FindIC cross-reference database, the EPF6024AQC208-2N is marked as a "complete replacement" with identical electrical performance.
What is the maximum clock frequency of the EPF6024AQI208-2N?
The EPF6024AQI208-2N has a maximum internal clock frequency of 153 MHz per the Altera FLEX 6000 datasheet. This rating applies to the global clock network driving the logic element flip-flops. Real-world design frequency depends on routing delays, fan-out, and the number of logic levels in the critical path; Quartus II timing analysis is required to confirm achievable fMAX for a specific design.
How many user I/O pins does the EPF6024AQI208-2N have?
The EPF6024AQI208-2N provides 171 configurable user I/O pins plus 4 dedicated inputs (for clock and global control) per the Altera FLEX 6000 datasheet. The remaining pins of the 208-pin PQFP package are allocated to power, ground, JTAG, and configuration. The I/O banks support 3.3 V LVCMOS/LVTTL signaling at the supported toggle rates.
Hey Google, can the EPF6024AQI208-2N be replaced by a Cyclone or modern Intel FPGA?
No - the EPF6024AQI208-2N cannot be directly replaced by a Cyclone or modern Intel FPGA because the Cyclone family uses a BGA or TQFP package, not the PQFP-208 footprint, and has a different pinout, JTAG pin assignment, and configuration scheme. A Cyclone replacement requires a PCB redesign. Within the same PQFP-208 footprint, the only drop-in FLEX 6000 alternatives are the EPF6024AQC208-2N and EPF6024AQI208-2.
What are the key specifications of the EPF6024AQI208-2N that engineers should know?
The EPF6024AQI208-2N is a 24,000-gate SRAM FPGA with 1,960 logic elements, 171 user I/O pins, 4 dedicated inputs, a 153 MHz maximum clock frequency, 3.3 V core supply, and a PQFP-208 package. Configuration is volatile via Passive Serial or Passive Parallel schemes, requiring an external EPC memory. JTAG (IEEE 1149.1) is supported. The part is obsolete and has limited distributor stock as of 2026-09-12.

Selection Guide

Choose the EPF6024AQI208-2N when your design requires a 24,000-gate SRAM FPGA in a PQFP-208 package, Industrial -40C to +85C operation, and RoHS lead-free compliance. The -2 speed grade (153 MHz) provides comfortable timing margin for most glue-logic designs. If your product does not require RoHS and is sold in markets that accept leaded finishes, substitute the EPF6024AQI208-2 for lower cost. If your application is Commercial-temperature and indoor, the EPF6024AQC208-2N offers identical performance with relaxed thermal rating. If your design is timing-critical, the EPF6024AQC208-3N provides the -3 speed grade. For modern new designs, prefer FLEX 10K or Cyclone families via PCB redesign.

Key Differentiators

  • Industrial temperature grade with lead-free RoHS finish (vs EPF6024AQC208-2N)
  • -2 speed grade for balanced fMAX margin (vs EPF6024AQI208-1N)
  • Lead-free N suffix for global RoHS compliance (vs EPF6024AQI208-2)
  • PQFP-208 fine-pitch SMD package for hand-reworkable designs (vs EPF6024ABC256-3 (BGA-256))

Design Notes

The EPF6024AQI208-2N requires a stable 3.3 V VCCINT supply with decoupling of at least 0.1 uF and 10 uF ceramic capacitors near every VCCINT/GND pair (pins 3/6, 19/22, 35/38, etc.). The I/O banks also require a separate VCCIO rail at 3.3 V; if 5 V inputs are present, use external series resistors or level shifters. Estimated core current draw for a fully-utilized design at 100 MHz is approximately 50-100 mA; design the regulator with at least 30% headroom. During configuration, the FPGA pulls transient current bursts up to 200 mA - bulk decoupling on the 3.3 V rail is recommended.

The PQFP-208 package has a 0.5 mm lead pitch, requiring PCB land patterns designed per IPC-7351 guidelines with proper solder mask slivers. Maintain at least 4 oz copper on power planes for VCCINT/VCCIO to handle switching currents. Keep configuration clock (DCLK) trace length under 50 mm and route it away from high-speed switching signals to avoid jitter-induced configuration errors. Provide a ground plane directly under the device for thermal dissipation; the PQFP-208 has a typical theta_JA of approximately 25-30 C/W in still air, but adequate copper pours are still required.

Estimated power-on configuration timing: the FLEX 6000 device enters configuration mode within 5 us of nCONFIG rising; ensure the host controller or EPC memory holds nSTATUS high during this window. A common mistake is leaving the nCONFIG pin floating - this can cause intermittent configuration failures. Always tie nCONFIG to VCCIO through a 10 kohm resistor if not actively driven. Also verify CONF_DONE has a proper pull-up (typically 10 kohm to VCCIO) - without it, the host cannot detect successful configuration completion.

Separate analog and digital ground returns where possible; the 171 user I/O switching edges create ground bounce that can couple into adjacent sensitive analog inputs. Series-terminate output traces longer than 50 mm with a 33-ohm resistor to control overshoot. Place the EPC configuration memory in the same quadrant as the FPGA to minimize DCLK skew. JTAG chain integrity requires TCK termination to ground near the FPGA and short TCK-to-TDI/TMS trace stubs (under 5 mm) to avoid ringback on the scan chain.
