Typical Applications
EPM3064ATC100-4N is suitable for 6 applications: Microcontroller I/O Expansion, Address Decoding and Chip Select Logic, Legacy PLC and Industrial Control Modernization, Bus Interface Bridging, State Machine and Timing Control, Replacing Discrete TTL/CMOS Glue Logic.
Microcontroller I/O Expansion
The EPM3064ATC100-4N is well suited for microcontroller I/O expansion where a small MCU has too few pins to drive peripherals. Its 66 user I/O pins and 4.5 ns pin-to-pin delay allow it to function as a high-speed port expander, decoding MCU address/data lines and generating per-chip-select signals in real time. The 3.3 V VCCINT and selectable 3.3 V/2.5 V VCCIO mean the device can interface directly with 3.3 V MCUs and 2.5 V peripherals without level shifters. Designers typically place the CPLD between the MCU bus and downstream devices, replacing discrete 74-series glue logic with a single reprogrammable part. The EEPROM-based non-volatile configuration boots in microseconds, eliminating the boot delay of an FPGA, which is critical for deterministic system startup.
Recommended
Address Decoding and Chip Select Logic
The EPM3064ATC100-4N excels at address decoding for memory-mapped systems. With 64 macro cells and 4.5 ns propagation delay, it can decode multi-bit address buses and produce fast chip-select signals for SRAM, flash, and peripheral ICs. The 2 Logic Array Blocks (LABs) and 1,250 usable gates provide ample headroom for complex decode equations. Compared to discrete 74HC138/139 decoders, this CPLD allows arbitrary custom decode maps in a single chip, reducing board area. The JTAG ISP interface per IEEE 1149.1 means decode logic can be updated on-board during prototype iterations without removing the part. With 3.3 V VCC and 2.5 V/3.3 V VCCIO options, it interfaces cleanly with both legacy 3.3 V memory and modern low-voltage ASICs.
Recommended
Legacy PLC and Industrial Control Modernization
The EPM3064ATC100-4N is widely used to upgrade legacy PLC and industrial control designs where original discrete logic has become obsolete or hard to source. Its 66 I/O pins and EEPROM-based non-volatile configuration mean it can replicate the function of multiple 74-series TTL/CMOS chips in a single 100-TQFP, reducing component count and improving reliability. The 4.5 ns tPD supports real-time control loops typical in PLC scan architectures, while 222.2 MHz counter frequency enables high-speed event counting. Designers value the deterministic propagation delay - unlike microcontrollers, CPLD outputs respond in fixed hardware time, which is essential for safety-critical industrial timing. The commercial 0C to +70C range suits cabinet-mounted equipment, and the JTAG ISP allows field re-programming for product-line variants.
Recommended
Bus Interface Bridging
The EPM3064ATC100-4N is frequently used as a bus interface bridge between incompatible logic standards and protocols. With 66 user I/O pins and configurable 3.3 V or 2.5 V VCCIO banks, it can connect a 3.3 V microcontroller to a 2.5 V ASIC without external level shifters. The 4.5 ns pin-to-pin delay is fast enough for protocols up to about 100 MHz, covering most parallel buses. Its 64 macro cells can implement FIFO flag logic, handshaking state machines, and protocol converters in a single device. EEPROM non-volatility means the bridge configuration is retained through power cycles, eliminating the FPGA configuration flash overhead. This makes it ideal for legacy-to-modern bus adapters in test equipment and instrumentation.
Recommended
State Machine and Timing Control
The EPM3064ATC100-4N is a natural fit for finite state machines and timing control applications. Its 64 macro cells each contain a flip-flop, giving roughly 128 flip-flops total plus combinatorial logic, more than enough for medium-complexity state machines. The 4.5 ns tPD and 222.2 MHz counter frequency allow precise multi-phase timing generation with sub-nanosecond jitter. Compared to a microcontroller implementation, a CPLD-based state machine responds in deterministic hardware time and is immune to interrupt latency. The JTAG ISP interface allows in-system updates during development, and the EEPROM-based configuration retains the state machine definition through power cycles. Typical uses include motor control sequencers, PWM generators, and protocol frame delimiters.
Recommended
Replacing Discrete TTL/CMOS Glue Logic
The EPM3064ATC100-4N is a direct modern replacement for boards stuffed with dozens of 74HC/74HCT/74F-series glue logic chips. With 1,250 usable gates and 64 macro cells, a single EPM3064ATC100-4N can replace 5 to 20 small-scale integration gates, dramatically reducing PCB area, power consumption, and BOM complexity. The 100-pin TQFP footprint replaces multiple 14-pin and 20-pin SOIC packages. 3.3 V VCC matches modern logic levels, while the JTAG ISP interface per IEEE 1149.1/1532 allows late-stage design changes without respinning the board. The EEPROM non-volatile configuration removes the need for boot PROMs, and the deterministic 4.5 ns timing eliminates timing analysis surprises. Designers typically use this part when modernizing legacy 5 V or 3.3 V logic designs.

Key Differentiators
- Fastest speed grade in MAX 3000A TQFP-100 family (vs EPM3064ATC100-10N)
- Industrial temperature option available in same package (vs EPM3064ATI100-10N)
- Active migration path to MAX 7000A family (vs EPM7064AETC100-10N)
Design Notes
Estimated: at typical CMOS switching activity on 66 I/O pins at 100 MHz, the EPM3064ATC100-4N consumes roughly 200-400 mW from VCCINT (3.3 V). Decouple each VCC pin with a 0.1 uF ceramic capacitor placed within 3 mm of the pin, and add a single 10 uF bulk capacitor near the package. VCCIO should be decoupled separately because output switching transients on the I/O bank can inject noise into the core supply through shared silicon substrate.
The 100-pin TQFP has 0.5 mm lead pitch and requires careful PCB layout: use a solder paste stencil of 4-5 mil thickness, reflow in a profiled oven with peak temperature not exceeding 245C for lead-free assembly, and ensure traces fan out from pads at 45 degree angles to avoid solder bridges. The exposed-pad center (if present on this package variant) should be soldered to a ground pour for thermal relief. Use a ground plane on layer 2 directly under the device to control return paths for high-speed I/O.
Common pitfalls: (1) JTAG chain order - if multiple JTAG devices share TCK/TMS, ensure proper TDI-to-TDO daisy chain or use the JTAG chain configurer in Quartus II; (2) leaving JTAG pins floating - always pull TCK to ground through 10 kohm and TMS/TDI to VCCIO through 10 kohm to prevent spurious ISP entry; (3) mixing VCCIO voltages - the I/O bank only supports one voltage at a time, either 3.3 V or 2.5 V, not both on different pins; (4) exceeding maximum I/O current per pin (typically 25 mA DC). Estimated thermal resistance theta_JA for 100-TQFP is approximately 35-45 C/W.
Compliance Information
RoHS compliance status not directly stated in the verified web data; the trailing 'N' suffix in Altera part numbers typically indicates lead-free / RoHS-compliant termination. AEC-Q100 is not applicable as this is a commercial/industrial-grade programmable logic IC.
