Safe Operating Area (SOA) & Thermal Characteristics
No official SOA curve available for this digital IC. Always operate within absolute maximum ratings specified in the datasheet. Ensure adequate cooling and derate as needed.
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.

Key Differentiators
- Fastest speed grade in MAX 3064A 44-PLCC family (vs EPM3064ALC44-10N)
- Lead-free ('-N') suffix for modern RoHS-compliant assemblies (vs EPM3064ALC44-4)
- Highest I/O count available in 44-pin PLCC MAX 3000A (vs MAX 3032A 44-PLCC devices)
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.
