EPM3064ALC44-4N Overview
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that contains multiple PAL-like macrocells interconnected through a central programmable interconnect matrix. CPLDs sit hierarchically above simple PLDs (PAL/GAL) and below FPGAs in the programmable logic taxonomy, offering deterministic timing, instant-on operation from on-chip EEPROM, and superior pin-locking for stable board revisions. The MAX 3000A architecture is widely used as low-cost glue logic in industrial, telecom, and consumer designs.
Key features include 3.3 V in-system programmability (ISP) via the built-in IEEE Std 1149.1 JTAG interface, MultiVolt I/O supporting 5.0 V, 3.3 V, and 2.5 V logic levels on output and input pins, hot-socketing support for live board insertion, and a 4.5 ns combinatorial propagation delay that enables high-speed state-machine and decoder implementations. The on-chip EEPROM configuration memory eliminates external boot devices and supports thousands of reprogram cycles.
The MAX 3000A architecture uses a classic AND-OR sum-of-products structure with 32 macrocells per LAB, sharing a global interconnect for predictable, deterministic timing. Each macrocell contains a programmable flip-flop, product-term selection logic, and a tri-state output buffer. The 64-macrocell device provides roughly 1,250 usable gates - well suited for address decoding, bus arbitration, peripheral control, and small state machines.
Typical applications include industrial control boards, telecom line-card glue logic, peripheral interface bridging (e.g., local-bus to ISA, GPIO expansion), printer and storage controller boards, and legacy system maintenance where instant-on non-volatile logic is required without an external boot PROM.
When designing with the EPM3064ALC44-4N, ensure the JTAG chain is properly terminated per IEEE 1149.1 and that I/O banks observe the MultiVolt VCCIO supply requirements; mixing 5 V and 3.3 V signals in the same bank without proper VCCIO selection is a common pitfall.

Typical Applications
EPM3064ALC44-4N is suitable for 6 applications: Industrial Glue Logic and Address Decoding, Legacy Peripheral Bus Bridging, Telecom Line Card Interface Logic, Printer and Storage Controller Boards, Embedded System GPIO Expansion and Custom I/O, Test Equipment and Lab Instrumentation.
Industrial Glue Logic and Address Decoding
The EPM3064ALC44-4N excels in industrial control boards as a deterministic glue-logic replacement for multiple 74-series TTL chips. With 64 macrocells and 34 I/O pins, the device can decode a full 24-bit address bus, generate chip-select strobes for memory and peripherals, and arbitrate interrupts - all in a single non-volatile device. The 4.5 ns pin-to-pin delay ensures no wait-state insertion is needed at 50 MHz bus speeds. Instant-on from on-chip EEPROM is critical for industrial PLCs that must boot deterministically without firmware loaders.
Recommended
Legacy Peripheral Bus Bridging
The EPM3064ALC44-4N is widely used to bridge between legacy 5 V peripheral buses (ISA, PC/104, SCSI) and modern 3.3 V processors. Its MultiVolt I/O can directly interface 5.0 V outputs while running from a 3.3 V core, eliminating external level-translator buffers. The 34 user I/O pins accommodate full 16-bit data plus 8-bit control signal mapping. Designers commonly implement custom protocol converters and timing-stretcher functions that legacy ASICs cannot provide cost-effectively.
Recommended
Telecom Line Card Interface Logic
Telecom line cards use the EPM3064ALC44-4N to implement HDLC framing, TDM bus multiplexing, and clock-data recovery control loops. The 222.2 MHz fMAX comfortably handles 77.76 MHz STS-3 tributary rates with margin, and the deterministic 4.5 ns propagation delay ensures jitter-free control signal timing. The hot-socketing capability allows field replacement of line cards without shutting down backplane power, a critical NEBS requirement in central-office deployments.
Recommended
Printer and Storage Controller Boards
Office printers, MFPs, and storage controllers use the EPM3064ALC44-4N to handle motor-control timing, sensor multiplexing, and interface glue between the main ASIC and peripherals such as scanners, USB hubs, and LCD panels. The EEPROM-based configuration provides instant-on behavior, eliminating boot delays and supporting fast power-cycle requirements. Hot-socketing support is valuable for field-serviceable storage modules where live board swap is needed.
Recommended
Embedded System GPIO Expansion and Custom I/O
Embedded SoCs and microcontrollers often lack sufficient GPIO or specialized timing flexibility. The EPM3064ALC44-4N attaches to a SPI or parallel host bus and provides 34 user I/O pins with custom logic, PWM generation, quadrature decoding, or matrix-keypad scanning implemented in hardware. The 1.25K usable gates accommodate 4-5 typical state machines concurrently, and the JTAG ISP allows firmware engineers to update logic behavior without re-spinning the board.
Recommended
Test Equipment and Lab Instrumentation
Test and measurement instruments use the EPM3064ALC44-4N for front-panel switch debouncing, display multiplexing, trigger logic, and custom timing generators. The deterministic 4.5 ns propagation delay is ideal for pulse-shaping circuits in TDR setups, and the JTAG ISP allows production-line reconfiguration for different test profiles. The 44-pin PLCC package is socket-compatible for easy lab rework and prototype iteration.

- Lead-free ('-N') suffix for modern RoHS-compliant assemblies (vs EPM3064ALC44-4)

Design Notes
The EPM3064ALC44-4N requires a stable 3.3 V core supply with at least 100 mA of headroom for in-system programming peaks. Decouple each VCC pin (typically pins 7, 19, 31, 43 on the 44-pin PLCC) with a 0.1 uF ceramic capacitor placed within 5 mm of the pin. Add a bulk 10 uF tantalum or ceramic capacitor near the device to suppress programming-current transients that can corrupt configuration EEPROM if VCC sags below 3.0 V.
Place a 4.7 kohm pull-up resistor on each JTAG signal (TDI, TMS, TCK) to ensure a defined logic state during power-up. The TDO pin should be left floating or pulled up externally. Route JTAG signals away from clock traces and noisy power-switching nodes to prevent ISP failures. Maintain the JTAG chain length below 6 inches if running at TCK > 10 MHz.
When mixing 5.0 V inputs with 3.3 V VCCIO, note that the I/O pins tolerate 5.0 V input levels only when the corresponding I/O bank VCCIO is at 3.3 V or higher. Connecting 5 V outputs to a 2.5 V VCCIO bank without external clamping is a common failure mode. Series resistors (33 ohm) on high-speed outputs help dampen transmission-line ringing on the 44-pin PLCC lead-frame inductance.
Do not exceed 200 mA total I/O sink current per GND pin (4 GND pins on 44-PLCC). Distribute heavy loads across multiple pins to avoid GND-bounce-induced JTAG failures. Always perform a blank-check and IDCODE verification before ISP programming; programming the wrong device on a shared JTAG chain is a leading cause of field returns.
Compliance Information
The '-N' suffix indicates lead-free matte-tin plating per Intel/Altera MAX 3000A datasheet family specification. Commercial temperature grade only (0C to +70C); no AEC-Q100 automotive grade variant exists in MAX 3064A. Not halogen-free certified per available data.
