EPM3064ATC100-4 Overview
A CPLD (Complex Programmable Logic Device) is a non-volatile, flash/EEPROM-backed programmable logic device that implements combinational and sequential logic using a sum-of-products architecture organized as macro cells. In the broader hierarchy, the CPLD sits between simple SPLDs/PLDs and FPGAs: it provides deterministic, ultra-fast pin-to-pin timing (often sub-5 ns), instant-on behavior, and high-drive I/O - making it the workhorse for glue logic, bus bridging, and power-up sequencing. The MAX 3000A family is Altera's classic 3.3 V CPLD line, with in-system programmability via IEEE 1149.1 JTAG.
Key features include 600-10,000 usable gates, in-system programmability (ISP) through the JTAG interface, MultiVolt I/O supporting 2.5 V, 3.3 V, and 5.0 V mixed-voltage interfacing, and four dedicated input pins for high-speed control signals. The CMOS EEPROM process gives non-volatile configuration with zero standby power, and the TQFP-100 package supports surface-mount manufacturing with standard JEDEC reflow profiles.
The device is built on a 5-level Altera MAX architecture with each macro cell containing a programmable AND/OR array, a configurable flip-flop, and fast product-term steering. Programmable interconnect couples the LABs with predictable, deterministic timing - critical for replacing discrete 74LS/74HC glue logic, asynchronous bus bridges, and PWM/timer peripherals that PLLs and microcontrollers cannot easily handle.
Typical applications include bus decode and address latching in legacy x86/embedded systems, asynchronous SRAM/Flash glue logic, motor-control PWM and timer replacement, industrial PLC I/O expansion, and power-sequencing networks for multi-rail systems. Its instant-on behavior also suits hot-swap controllers, ISA-to-PCI bridges, and high-drive LED/relay scan matrices.
When designing with the EPM3064ATC100-4, allocate at least four pins as JTAG (TCK, TMS, TDI, TDO) plus one TRST, follow Altera's ByteBlaster pinout recommendations, and respect the 3.3 V VCCINT supply. Choose the -4 speed grade for 4.5 ns tPD; slower -7 and -10 grades are pin-compatible for cost-sensitive timing paths.

Typical Applications
EPM3064ATC100-4 is suitable for 6 applications: Legacy Bus Decode and Address Latching, PWM and Motor Control Timing Replacement, Industrial PLC I/O Expansion, Power Sequencing for Multi-Rail Systems, LED Display and Relay Scan Matrix Drivers, Legacy PCI-to-ISA Bridge Logic.
Legacy Bus Decode and Address Latching
The EPM3064ATC100-4 replaces discrete 74LS/74HC glue logic for ISA, PC/104, and embedded microcontroller bus decode with deterministic 4.5 ns tPD. Its 64 macro cells provide enough product terms to decode up to 32 address lines while generating chip-select, read/write strobes, and interrupt acknowledge signals simultaneously. The non-volatile EEPROM eliminates boot-up wait states, and MultiVolt I/O directly interfaces 5 V microcontrollers to 3.3 V peripherals without level shifters, simplifying legacy system retrofits in industrial controllers.
Recommended
PWM and Motor Control Timing Replacement
The EPM3064ATC100-4 generates precision PWM signals up to 227.3 MHz counter frequency for motor-control and SMPS applications, replacing multiple 555 timers and discrete counters. Its 64 macro cells allow simultaneous generation of 6+ phase-shifted PWM channels with dead-time insertion and fault handling. The 100-TQFP package supports industrial temperature ranges and the MultiVolt I/O directly drives 5 V gate drivers, making it a compact solution for three-phase BLDC and stepper drivers.
Recommended
Industrial PLC I/O Expansion
The EPM3064ATC100-4 expands discrete I/O on industrial PLCs by implementing shift-register interfaces, debouncers, and multiplexing logic in a single chip. Its 34 user I/O pins handle up to 32 optically-isolated inputs plus JTAG, while the 4.5 ns tPD supports deterministic scan rates above 1 MHz. The MAX 3000A architecture provides high-noise-immunity CMOS EEPROM cells suitable for industrial environments, and the JTAG ISP interface enables field firmware updates without powering down the line.
Recommended
Power Sequencing for Multi-Rail Systems
The EPM3064ATC100-4 generates programmable power-up/power-down sequencing for systems with 4-8 voltage rails using its deterministic EEPROM-backed macro cell logic. With 4.5 ns tPD the CPLD can enforce strict rail-to-rail timing budgets (typical 10-50 ms staggered delays) for FPGAs, ASICs, and DSPs that require specific enable sequences. The non-volatile configuration means sequencing starts instantly at power-on without processor intervention, critical for ASIL-rated automotive and medical systems.
Recommended
LED Display and Relay Scan Matrix Drivers
The EPM3064ATC100-4 drives large LED/relay multiplex matrices by implementing row/column scan logic and PWM dimming in hardware. Its 34 high-drive I/O pins handle up to 8x8 matrix scans at 100+ Hz refresh rates, while 64 macro cells provide per-channel brightness control and dead-time generation. The MultiVolt I/O directly interfaces 5 V LED drivers and 24 V relay coils via external transistors, making it ideal for industrial signage, instrumentation front panels, and elevator indicator arrays.
Recommended
Legacy PCI-to-ISA Bridge Logic
The EPM3064ATC100-4 implements PCI-to-ISA bridge glue logic for legacy embedded systems, replacing multiple PAL/GAL devices with a single deterministic CPLD. Its 4.5 ns tPD meets PCI 33 MHz timing budgets (15 ns cycle, 7 ns setup), and 64 macro cells are sufficient to decode PCI address/data/control signals while generating ISA bus cycles. The 100-TQFP package and 3.3 V core with 5 V-tolerant I/O simplify mixed-voltage system integration, particularly in industrial PCs and medical instruments.

Key Differentiators
- Fastest -4 speed grade in the MAX 3000A 100-TQFP family (vs EPM3064ATC100-10)
- Available as Pb-free variant (EPM3064ATC100-4N) with identical specs (vs EPM3064ATC100-4 (SnPb))
- Industrial temperature option via I-suffixed family member (vs EPM3064ATI100-10N)
Design Notes
Estimated: VCCINT must be regulated at 3.3 V +/- 5% with at least 100 mA peak capacity per EPM3064ATC100-4 device. VCCIO can be independently set to 2.5 V, 3.3 V, or 5.0 V to interface with mixed-voltage peripherals, but VCCINT must remain at 3.3 V. Place 0.1 uF decoupling caps on every VCCINT/VCCIO pin pair plus a single 10 uF bulk cap near the package. Power-up sequencing is not required between VCCINT and VCCIO - the MultiVolt I/O tolerates either rail coming up first per MAX 3000A datasheet.
The 100-TQFP package has 0.5 mm pitch and requires careful PCB layout. Route all JTAG signals (TCK, TMS, TDI, TDO) as a controlled-impedance group with 4.7 kohm pull-ups on TMS and TDI per Altera's ByteBlaster reference design. Keep JTAG traces away from switching signals; add a ground guard ring around the JTAG header. Allocate at least 4 layers (signal/ground/power/signal) for proper return paths and to maintain signal integrity on the 4.5 ns timing paths.
Do not confuse the EPM3064ATC100-4 (commercial temp, SnPb) with the EPM3064ATC100-4N (commercial temp, Pb-free) or EPM3064ATI100-10N (industrial temp, 10 ns grade) - they share the same package but different temperature ranges and finishes. Also avoid mixing speed grades (-4, -7, -10) when programming with Quartus II, as the fitter output will produce timing violations. Always configure unused I/O pins as outputs driving low (per MAX 3000A datasheet) to minimize power consumption and switching noise.
Compliance Information
RoHS/REACH compliance not explicitly stated in verified data; -4N and -10NA variants are Pb-free per their suffix designation. AEC-Q100 not applicable for legacy Altera CPLD line. Always request official manufacturer declarations for RoHS-restricted designs.
