Typical Applications
EPM3064ALC44-10N is suitable for 6 applications: Legacy Industrial PLC I/O Expansion, ISA / PCI Bus Address Decoding, Power-Up Sequencing for Multi-Rail Systems, Glue-Logic Replacement for 74-Series TTL, State-Machine and Control Logic, Test and Measurement Equipment Front-End.
Legacy Industrial PLC I/O Expansion
The EPM3064ALC44-10N is widely used as a glue-logic and I/O expansion CPLD in legacy industrial PLC designs where deterministic timing and non-volatile instant-on configuration are required. Its 64 macrocells easily accommodate 8-16 bit bidirectional register interfaces, interrupt controllers, and opto-isolator signal conditioning logic. The 10 ns tPD ensures sub-microsecond response to fast PLC scan cycles, while the 34 I/O pins handle typical 16-input / 16-output signal conditioning. The 3.3 V core with MultiVolt I/O supports mixed 5 V sensor buses via simple resistive level shifters, preserving backward compatibility with installed PLC bases.
Recommended
ISA / PCI Bus Address Decoding
The EPM3064ALC44-10N's deterministic 10 ns tPD and 64 macrocells make it ideal for ISA-bus and legacy PCI-bus address decoding, chip-select generation, and wait-state insertion logic. It replaces 4-6 discrete 74F/74LS PAL/GAL devices with a single CPLD, reducing PCB area and improving reliability. Its JTAG-based in-system programmability (IEEE 1149.1) allows board-level decoding-map updates without removing the device from the socket. The MultiVolt I/O supports 5 V ISA bus signalling directly when VCCIO is biased at 3.3 V with series damping resistors.
Recommended
Power-Up Sequencing for Multi-Rail Systems
The EPM3064ALC44-10N is commonly deployed as a power-up sequencer in multi-rail embedded boards, where its non-volatile EEPROM configuration ensures deterministic rail ordering at cold-start without software intervention. Its 64 macrocells can encode up to 16 independent power-good state machines, while the 34 I/O pins drive dozens of enable and reset lines. The 227.3 MHz internal counter frequency supports fine-grained delay steps in the microsecond range, critical for sequencing modern PMICs and SoCs that demand specific power-rail ramp profiles. The PLCC-44 socketed package also allows last-minute logic reconfiguration during board bring-up.
Recommended
Glue-Logic Replacement for 74-Series TTL
Engineers use the EPM3064ALC44-10N to consolidate 4-8 discrete 74LS, 74HC, or 74F TTL packages - latches, multiplexers, decoders, and small state machines - into a single CPLD. This reduces PCB real-estate by up to 60%, eliminates interconnect timing skew between gates, and provides easy logic revision through JTAG reprogramming rather than board rework. The 10 ns tPD matches or beats 74LS TTL propagation delays, and the 3.3 V core draws a fraction of the bipolar 74LS quiescent current. Open-drain output option on each I/O pin preserves wired-OR signalling compatibility with legacy 74LS open-collector bus architectures.
Recommended
State-Machine and Control Logic
The EPM3064ALC44-10N is well-suited for implementing complex finite state machines, protocol converters, and custom control sequencers in embedded designs. Each macrocell supports D/T/JK flip-flop operation with clear, preset, and clock-enable signals, and the LAB-wide control products enable wide-input decoding up to 32 product terms per macrocell. With 64 macrocells and 4 LABs, designers can encode state machines with 8-16 states plus auxiliary counters, suitable for RS-232/RS-485 protocol conversion, custom keyboard scanners, and motor-control sequencers. The 227.3 MHz counter frequency supports high-speed PWM generation and quadrature decoding up to several hundred kHz.
Recommended
Test and Measurement Equipment Front-End
The EPM3064ALC44-10N is deployed in legacy test and measurement instruments for front-panel switch debouncing, range-switching relay drivers, and A/D converter timing/control logic. Its 34 I/O pins handle multiple front-panel rotary switches and pushbuttons with hardware debouncing implemented in just a few macrocells each. The deterministic 10 ns tPD ensures glitch-free range switching during sensitive ADC acquisitions, and the JTAG interface allows in-field logic updates as test procedures evolve. The PLCC-44 socketed form factor simplifies board-level replacement during calibration cycles and end-of-life service events on long-lifecycle industrial T&M gear.

Design Notes
Estimated: at VCCINT = 3.3 V with all 34 I/Os toggling at 50 MHz with 50 pF loads, ICCINT is approximately 50-80 mA. Provide a 0.1 Β΅F ceramic decoupling capacitor within 5 mm of each VCCINT/GND pin pair, plus a single 10 Β΅F bulk tantalum or ceramic capacitor on the board supply rail. For multi-board systems, add a ferrite bead in series with VCCINT to suppress switching noise injection into the JTAG chain.
The 44-pin PLCC (LC44) package uses a 1.27 mm lead pitch on a JEDEC-standard land pattern. Use a PLCC-44 through-hole socket (e.g., 3M 8444-21B1-RK-TN or equivalent) to allow easy field replacement of this obsolete part. For surface-mount designs where socketing is undesirable, consider the pin-compatible EPM3064ATI44-10N in 44-pin TQFP, but note the land pattern is not interchangeable. Ground pins 11, 32 must be connected to a low-impedance ground plane with vias placed within 2 mm of each pin.
The MAX 3000A family is supported only by Altera Quartus versions up to 13.0sp1; later Quartus versions dropped MAX 3000A support. Maintain a legacy Quartus 13.0sp1 installation with the MAX 3000A device library to generate .pof programming files. Do not use 5 V signals directly on I/O pins without verifying MultiVolt VCCIO range - the EPM3064ALC44-10N VCCIO is 3.0-3.6 V; 5 V tolerance is not specified. Unused I/Os should be configured as outputs driving low or left NC per JTAG chain requirements to minimize ICCINT standby.
JTAG chain integrity is critical for ISP. Place TCK, TMS, TDI, TDO traces with 50 ohm characteristic impedance and keep trace lengths under 50 mm if possible. Add 10 kohm pull-ups on TMS and TDI to keep the JTAG state machine in a known idle state during board power-up. When chaining multiple EPM3064A devices on a single JTAG bus, ensure TDO-to-TDI propagation delay does not exceed the TCK period - the 10 ns tPD is normally adequate for two-device chains at TCK = 10 MHz.
