Typical Applications
EPM3064ATC100-7 is suitable for 7 applications: Industrial Glue Logic Replacement, PCI Bus Interface / Glue Logic, Power-Up / Power-Down Sequencing Logic, Microprocessor Address Decoding and Chip-Select Generation, LED Display and Multiplexed Panel Drivers, Factory Automation Sensor Multiplexing, Legacy Peripheral Interface Bridging.
Industrial Glue Logic Replacement
The EPM3064ATC100-7 is purpose-built to replace 5-15 discrete 74-series TTL/CMOS logic ICs in industrial glue logic applications, where its 64 macrocells and 2 LABs can implement the equivalent of 200-400 discrete gates while fitting in a single 100-pin TQFP. With 7.5 ns pin-to-pin propagation delay and 135.1 MHz internal counter frequency, it comfortably handles address decoding, interrupt prioritization, and chip-select generation for legacy 8/16-bit microprocessor boards. The EEPROM-based non-volatile configuration eliminates the boot PROM required by SRAM-based FPGAs, simplifying the BOM and reducing board area. JTAG-based ISP (IEEE 1149.1) allows field upgrades without removing the chip from the board, a key requirement for factory-floor equipment that cannot easily be taken offline. The wide operating temperature range and 3.3V VCCINT with 5V-tolerant inputs make it compatible with both modern 3.3V microcontrollers and legacy 5V peripheral ICs. Industrial designers favor this part for cost-sensitive PLC I/O expansion modules, motor-control front-end logic, and sensor-signal conditioning boards.
Recommended
PCI Bus Interface / Glue Logic
The EPM3064ATC100-7 is fully compliant with the PCI Local Bus Specification Revision 2.2 in the -7 speed grade, making it ideal for PCI add-in card glue logic including address decoding, command validation, and bus-cycle state machines. With 66 user I/Os and 7.5 ns pin-to-pin delay, the device comfortably meets PCI's 33 MHz / 66 MHz timing requirements while leaving headroom for state-machine logic. The dual VCCINT (3.3V core) and VCCIO (2.5V or 3.3V I/O) supplies allow mixed-voltage interfacing with both 5V-tolerant legacy peripherals and modern 3.3V ASICs. Designers use this CPLD to implement PCI target devices, configuration-space registers, and arbiter front-end logic without resorting to a full FPGA. The 100-pin TQFP package is the standard footprint for PCI card designs, enabling drop-in upgrades between -4, -7, and -10 speed grades. JTAG boundary-scan support (IEEE 1149.1) enables in-system test access to all pins, a critical requirement for PCI compliance testing. Designers building legacy PCI cards still in production use this part for its deterministic timing, instant-on behavior, and proven long-term reliability.
Recommended
Power-Up / Power-Down Sequencing Logic
The EPM3064ATC100-7's EEPROM-based non-volatile configuration makes it ideal for power-sequencing applications in multi-rail systems, where the CPLD must wake up in a known state and orchestrate the startup order of DC-DC converters, ASICs, and FPGAs. The 7.5 ns pin-to-pin delay is fast enough to assert and de-assert enable signals with microsecond precision, while 64 macrocells provide sufficient logic capacity for sequencing 8-16 independent rails with adjustable delays. The 3.3V VCCINT rail can typically be powered directly from an always-on supply or a small LDO, ensuring the CPLD is the first device to come alive in the system. With 66 user I/Os, designers can wire the CPLD directly to each rail's enable pin without external buffers. The JTAG ISP interface allows firmware engineers to update sequencing order in the field without re-spinning the PCB, a major advantage over hard-wired sequencer ICs. Industrial and telecom power systems commonly use this part for ATX-style sequencing, hot-swap controller logic, and PMBus-compatible rail monitoring. The deterministic, glitch-free EEPROM configuration ensures no spurious enable signals during power transitions.
Recommended
Microprocessor Address Decoding and Chip-Select Generation
The EPM3064ATC100-7 is a classic choice for address decoding and chip-select generation in 8/16/32-bit microprocessor systems, replacing 3-5 cascaded 74-series decoders (74HC138, 74HC139, 74HC154) with a single programmable device. With 64 macrocells and 7.5 ns pin-to-pin delay, the CPLD can decode 24-bit address buses and generate up to 16 individual chip-select outputs, each programmable with wait-state insertion and timing edges. The 66 user I/Os in the TQFP-100 package easily accommodate both wide address buses and multiple peripheral enables. Designers commonly use this part in legacy x86 embedded boards, 8051/MIPS system designs, and DSP daughter cards where deterministic chip-select timing is critical. The JTAG ISP interface enables last-minute address-map changes during prototype bring-up, eliminating the need for decoder-array rework. Combined with the EEPROM-based instant-on behavior, this part ensures peripherals are not spuriously selected during power-up - a common pitfall with discrete decoders that briefly glitch during supply ramp.
Recommended
LED Display and Multiplexed Panel Drivers
The EPM3064ATC100-7 excels in LED display driver and multiplexed panel applications, where its 64 macrocells can implement the row/column scanning state machine, brightness PWM, and display memory addressing logic. With 135.1 MHz internal counter frequency, the device can drive multiplexed 7-segment displays, dot-matrix LED panels, and small character LCD interfaces with refresh rates well above the 60Hz flicker limit. The 66 user I/Os accommodate direct connections to 8-row by 8-column dot-matrix panels without external driver ICs in smaller designs. The 7.5 ns pin-to-pin delay ensures clean timing edges for multiplexing without ghosting or crosstalk between rows. EEPROM configuration means the display pattern, brightness curves, and scan order are retained across power cycles without external flash. Industrial control panels, point-of-sale terminals, and instrument front panels commonly use this part for its deterministic timing and ability to consolidate multiple TTL driver chips into a single programmable device.
Recommended
Factory Automation Sensor Multiplexing
The EPM3064ATC100-7 is widely used in factory automation for sensor multiplexing and protocol bridging, where its 66 user I/Os and 7.5 ns timing can interface between industrial sensor arrays and a central PLC or controller. The device can implement custom serial protocols (RS-485, SPI, I2C, Modbus bridges), sensor de-bouncing, and time-multiplexing logic for cost-optimized analog front-ends. With 3.3V VCCINT and 5V-tolerant inputs, the CPLD easily bridges between modern 3.3V microcontrollers and 5V industrial sensor families. The wide industrial operating temperature range and robust CMOS EEPROM technology make it suitable for unattended factory-floor deployment. JTAG ISP enables firmware updates over the fieldbus without opening control cabinets, a major advantage for retrofit projects. Designers commonly use this part to consolidate 4-6 discrete protocol converter ICs into a single programmable device, reducing BOM cost and PCB area in PLC analog input modules, distributed I/O racks, and machine-vision front-end interfaces.
Recommended
Legacy Peripheral Interface Bridging
The EPM3064ATC100-7 is an excellent choice for legacy peripheral interface bridging, where its 66 user I/Os and flexible I/O voltage standards can translate between ISA, VME, PCI, and modern serial buses. With 64 macrocells, designers can implement custom bus arbitration, interrupt steering, and protocol conversion logic without external FIFOs or bus switches in low-throughput applications. The 7.5 ns pin-to-pin delay comfortably handles 33 MHz PCI and legacy 8 MHz ISA timing requirements. JTAG boundary-scan (IEEE 1149.1) provides test access to all pins, critical for legacy board bring-up and field diagnostics. The EEPROM-based configuration retains the bridge logic during power cycles, eliminating the boot sequence issues common with SRAM-based FPGAs. Industrial test equipment, medical imaging boards, and aerospace telemetry systems still rely on this part for its deterministic timing, proven reliability, and ability to operate at 3.3V with 5V-tolerant inputs for direct interfacing with legacy peripheral ICs.

Design Notes
The EPM3064ATC100-7 requires dual supplies: VCCINT must be held at 3.3V +/- 5% for the internal core, and VCCIO must be supplied per I/O bank requirements (2.5V or 3.3V). 5V tolerance on inputs exists but VCCIO cannot be set to 5V. Place one 0.1uF ceramic decoupling capacitor as close as possible to each VCCINT and VCCIO pin, with bulk 10-100uF tantalum or polymer caps on each supply rail. Power-up sequence is not strictly required because the EEPROM configuration is non-volatile, but for predictable JTAG ISP behavior bring up VCCINT first, then VCCIO, then drive JTAG signals.
Follow Altera's JTAG chain guidelines when multiple devices share the JTAG bus: connect TDI to TDO of the next device in series, share TMS and TCK in parallel, and place a 4.7k-10k pull-up resistor on TCK and TMS to keep the JTAG state machine in a known state during power-up. For high-speed designs (>50 MHz), keep JTAG trace lengths under 6 inches to prevent signal-integrity issues. Place the JTAG header within 2 inches of the CPLD, and route TDI/TDO away from switching power and clock signals to avoid coupling.
Common design pitfalls with the EPM3064ATC100-7: (1) Do not leave VCCIO floating - this prevents the I/O banks from driving outputs cleanly. (2) Do not use the dedicated INPUT/GCLK pin as a generic user I/O - it has special routing into the LAB clock network. (3) The -7 speed grade timing closure at 135 MHz counter frequency depends on Quartus fitter optimization; always check the timing report before sign-off. (4) For 5V input signals, the input voltage must not exceed VCCIO + 4.0V absolute maximum to avoid latch-up. (5) When migrating designs from older MAX 7000 series, note that the JTAG instruction set differs - update your BSDL file accordingly.
