Typical Applications
EPM3064ATC100-10 is suitable for 6 applications: Bus-Interface Glue Logic, Address Decoding and Chip-Select Generation, State-Machine Control, I/O Expansion Bridges, Legacy System Bring-Up, Embedded Control and Sequencing.
Bus-Interface Glue Logic
The EPM3064ATC100-10 is well-suited to bus-interface glue logic because its 10ns tPD and 34 user I/O pins comfortably handle address-latch, buffer, and transceiver control functions across multi-master buses. With 64 macrocells, designers can implement address decoding, chip-select generation, and interrupt steering for 8/16/32-bit microprocessor buses in a single device. The 3.3V core with MultiVolt I/O lets the same CPLD interface 1.8V peripherals and 5V-tolerant inputs, eliminating external level shifters. JTAG ISP per IEEE 1149.1 enables in-system updates of glue-logic revisions without board removal.
Recommended
Address Decoding and Chip-Select Generation
The 64-macrocell capacity of the EPM3064ATC100-10 maps directly to 32 to 64 independent chip-select outputs in a typical address-decoder pattern, making it a strong fit for legacy embedded platforms with multiple peripherals. Two global clocks with optional inversion support synchronous bank enables, while programmable output slew-rate control lets designers trade edge rate against EMI for memory-mapped expansion buses. The non-volatile EEPROM configuration guarantees chip-select outputs settle within microseconds of power-up, removing the boot-time race common with SRAM-based FPGAs.
Recommended
State-Machine Control
For state-machine control in industrial controllers, the EPM3064ATC100-10's deterministic 10ns tPD means each Moore or Mealy transition completes in a bounded number of clock cycles regardless of logic complexity. With 34 I/O and 64 macrocells, designers can implement multi-state sequencers controlling motors, valves, or test fixtures while retaining headroom for status LEDs and safety interlocks. The 2-LAB architecture provides predictable routing delays across the chip, simplifying timing closure. JTAG-based ISP allows last-minute state-machine revisions during factory bring-up.
Recommended
I/O Expansion Bridges
I/O expansion bridges for low-bandwidth peripherals - such as GPIO expansion, SPI-to-parallel conversion, or keypad scanning - are a classic MAX 3000A use case. The EPM3064ATC100-10's 34 user I/O pins, multi-voltage I/O support, and 10ns tPD enable seamless bridging between a microcontroller and downstream 1.8V / 3.3V peripherals. The 3.3V core draws modest quiescent current, and the TQFP-100 footprint provides easy hand-solder rework during prototyping. Two global clock signals allow synchronous multiplexing of input sources without external clock trees.
Recommended
Legacy System Bring-Up
When extending the life of installed equipment, the EPM3064ATC100-10 provides a known-quantity programmable logic replacement for obsolete TTL or PAL devices. The EEPROM configuration retains the design through power cycles without external boot memory, which is essential for unattended legacy telecom and industrial-control installations. Two global clocks and 34 I/O pins support drop-in replacement of multi-chip 74LS logic clusters, while JTAG ISP allows firmware refresh via existing test headers. The NRND status means designers should plan a long-term migration to MAX V or MAX 10 CPLDs.
Recommended
Embedded Control and Sequencing
The EPM3064ATC100-10 is commonly used for power-up sequencing, watchdog management, and reset distribution in embedded designs. Its deterministic 10ns timing, two global clocks, and 6-10 output enable signals make it straightforward to implement multi-rail power sequencers with precise inter-rail delays. The non-volatile EEPROM configuration means the sequencing logic is available within microseconds of VCC, well before any downstream MCU or ASIC completes its own reset. The TQFP-100 package allows placement adjacent to power-management ICs without trace-length concerns.

Key Differentiators
- TQFP-100 packaging with abundant third-party tool support (vs EPM7064AETC44-10N)
- Instant-on non-volatile EEPROM configuration (vs SRAM-based FPGAs in similar density)
- 10 ns deterministic tPD regardless of logic utilization (vs FPGA timing models)
Design Notes
JTAG pins (TCK, TMS, TDI, TDO) must remain accessible for in-system programming per IEEE 1149.1. Route these signals away from fast-switching clocks and noisy power planes; place a 10 kohm pull-up on TCK and TMS to keep the boundary-scan state machine in a known reset state when the test header is disconnected. Keep JTAG trace lengths under 6 inches to avoid signal-integrity issues.
Decouple each VCCINT pin with a 0.1 uF ceramic capacitor placed within 3 mm of the pin, plus a bulk 10 uF tantalum or ceramic near the TQFP-100 cluster. The MAX 3000A core draws modest current but the simultaneous-switching output current during ISP programming can sag the supply; bulk capacitance prevents programming failures.
Do not confuse EPM3064ATC100-10 (MAX 3000A) with EPM7064AETC44-10N (MAX 7000A in TQFP-44). They share the EPM prefix but differ in macrocell count, package, and pinout. Cross-reference search results that list the MAX 7000A as a "complete replacement" are misleading - it is a different package and requires PCB rework. Stay within MAX 3000A family members for true drop-in alternatives.
Use programmable slew-rate control to slow edge rates on long PCB traces to reduce EMI. The MAX 3000A supports both fast and slow slew rates per pin; for traces longer than 5 cm carrying clock or synchronous signals, configure slow slew to limit harmonic content. Combine with series termination for high-frequency outputs driving backplane connectors.
