EPM5064JC1 Overview
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits in the system hierarchy between simple SPLDs/PLDs and larger FPGAs. CPLDs use a macrocell-plus-PIA architecture where each macrocell contains an AND/OR array plus a flip-flop, while the PIA routes signals between LABs. This non-volatile, deterministic, single-pass architecture gives CPLDs predictable timing, instant-on behavior, and higher drive strength than SRAM-based FPGAs, making them ideal for glue logic, address decoding, bus interfacing, and state-machine replacement.
The EPM5064JC1 features 64 macrocells, 36 total inputs (7 dedicated + 28 I/O + 1 global clock), 1.25K usable gates, 62.5 MHz fCNT (internal counter frequency per FPGAkey), and an operating voltage of 5V. It belongs to the MAX 5000 family, the second-generation MAX architecture that followed the classic EP-series (EPM5032, EPM5016) and preceded the MAX 7000 family that added in-system programmability.
Architecturally, the EPM5064JC1 uses CMOS EPROM technology with a 4-LAB PIA fabric. Each LAB contains 16 macrocells; each macrocell contains an AND/OR array, a configurable flip-flop, and an I/O control block. Programming is one-time (OTP) via EPROM, requiring a UV-erasable window for reprogramming. The device consumes approximately 150 mA ICC and is specified for 0-70°C commercial operation (commercial-grade JC suffix).
Typical applications include 5V glue logic replacement, address decoding and bus interfacing, state-machine and control-logic implementation, peripheral controllers in industrial and telecom backplanes, and pin-compatible upgrades of older EP-series PLDs (EPM5032, EPM5016) where 64 macrocells are required. Designers migrating from EPM5032 (32 macrocells) to EPM5064 (64 macrocells) can re-use PLCC-44 footprints if their design fits the larger capacity.
When designing with this device, note that the EPM5064JC1 is a one-time-programmable EPROM part, so any logic change requires a new device. The PLCC-44 socket enables prototype iteration via UV-erasable reprogramming of the same physical package. For production runs of stable logic, the MAX 7000S or MAX II family is generally preferred for in-system programmability, but the MAX 5000 remains valued for long-life industrial systems where the original part is specified.

Typical Applications
EPM5064JC1 is suitable for 6 applications: 5V Glue Logic Replacement, Address Decoding & Bus Interfacing, State Machine & Control Logic, Peripheral Controllers in Industrial Backplanes, Pin-Compatible Upgrade of EPM5032 Designs, Legacy Telecom & Test Equipment.
5V Glue Logic Replacement
The EPM5064JC1's 64 macrocells, 28 I/O pins, and 5V operation make it a strong fit for replacing discrete TTL/CMOS glue logic in legacy backplane designs. With 50 MHz external clock capability and 4 LABs connected by a deterministic PIA, timing closure is straightforward - each signal path has fixed pin-to-pin delay, unlike FPGAs whose interconnect delay varies with placement. Designers migrating from 74xx-series address decoders, latches, and PALs can consolidate 5-10 discrete packages into one EPM5064JC1, reducing PCB area and BOM count while preserving 5V rail compatibility for legacy systems.
Recommended
Address Decoding & Bus Interfacing
The EPM5064JC1 is well-suited for address decoding and bus-interface bridging in 5V microprocessor and microcontroller systems. Its 36 total inputs (28 I/O + 7 dedicated + 1 clock) easily accept 24-32-bit address buses, while the 28 I/O outputs drive chip-select and strobe signals with strong CMOS output buffers. Each macrocell's configurable product-term allocation lets designers implement up to 64 sum-of-products equations, and the deterministic PIA timing ensures no decoding glitches across temperature. Industrial and telecom designs frequently use this device to glue ISA, VME, or proprietary buses to peripherals.
Recommended
State Machine & Control Logic
The EPM5064JC1 is a natural fit for Moore and Mealy state machines, sequential control logic, and protocol converters in industrial automation. Each macrocell contains a programmable flip-flop with selectable D/T/JK/SR flip-flop mode, giving designers up to 64 registered outputs - sufficient for complex multi-state controllers (sequencers, motor controllers, protocol engines). The EPROM-based non-volatile configuration means the state machine powers up in a known state on every cold-boot without an external configuration memory, a key advantage over SRAM-based FPGAs in safety-critical industrial applications.
Recommended
Peripheral Controllers in Industrial Backplanes
The EPM5064JC1's 5V tolerant I/O, commercial temperature range (0-70°C with JC suffix), and instant-on EPROM configuration make it reliable for peripheral controllers in industrial backplane cards. With 28 user I/O pins, designers can drive multiple opto-isolated interfaces, generate handshake and strobe signals, and implement custom DMA or interrupt controllers without external logic. The MAX 5000 family has decades of field-proven reliability in industrial PLCs, motor drives, and instrumentation where 5V supply rails remain standard. For extended -40°C to +85°C industrial temperatures, consider the EPM5064LI or migration to MAX II EPM240T100I5N.
Recommended
Pin-Compatible Upgrade of EPM5032 Designs
The EPM5064JC1 serves as a drop-in upgrade path for systems originally designed around the smaller EPM5032 (32 macrocells). Both parts share the 44-pin PLCC package footprint, so migrating to EPM5064 doubles the logic capacity without PCB rework. Designers targeting the same MAX 5000 family programming flow (MAX+PLUS II + Altera programming hardware) can re-target existing EPM5032 design files to the EPM5064 macrocell utilization. This upgrade is particularly attractive for legacy telecom line-card and instrumentation designs that have outgrown the 32-macrocell budget.
Recommended
Legacy Telecom & Test Equipment
The EPM5064JC1 is widely deployed in legacy telecom line cards, T1/E1 framers, protocol bridges, and test-and-measurement instruments where the MAX 5000 family was the de-facto glue-logic standard in the 1990s. These long-life systems often require exact drop-in replacements during repair because redesigning a 5V PCB is cost-prohibitive. The 64 macrocells and 50 MHz clock rate cover most glue-logic tasks in these systems, including address decoding, interrupt steering, and custom serial-protocol framing. Obsolete-component specialists maintain stock of the EPM5064JC1 specifically for this installed base.

Key Differentiators
- Drop-in 64-macrocell capacity with same MAX 5000 programming flow (vs EPM5032JC (32 macrocells))
- One-time-programmable EPROM technology ensures instant-on, no-configuration-memory (vs MAX II EPM240 (SRAM-based flash-configured CPLD))
- Lower-power LC grade offers reduced ICC for standby-sensitive systems (vs EPM5064JC1 (standard power))
Design Notes
The EPM5064JC1 is one-time-programmable (OTP) EPROM, not in-system programmable. Any logic change requires a UV-erasable window exposure (typically 20-30 minutes under UV-C) and a fresh programming cycle. Engineers prototyping iterations must budget for a UV eraser or stock of pre-programmed parts. For in-system programmability, migrate to MAX 7000S (EPM7128SLC84) or MAX II (EPM240T100C5N) - both share the MAX+PLUS II / Quartus II tool flow.
Use a machined-pin PLCC-44 socket (e.g. 3M 8444-21B1-RK or Aries 44-3554-10) for prototype boards to allow EPROM UV-erase-and-reprogram cycles. Decoupling: place one 0.1 µF ceramic cap and one 10 µF tantalum cap within 100 mils of each VCC pin (44-pin PLCC has 4 VCC pins total). The 5V supply should be clean - the MAX 5000 family does not have PLL-based power filtering, so noisy 5V rails couple directly to the macrocell flip-flop clocks.
MAX 5000 family devices have deterministic PIA-based interconnect, but propagation delay varies with product-term fan-in (3-5 ns per additional product term). For high-speed paths, minimize the number of cascaded product terms and avoid using the global clock for non-clock signals. The 50 MHz external clock limit applies to clocked macrocell flip-flops; combinational paths have tPD = 15-25 ns typical and should be budgeted accordingly. Use the Altera MAX+PLUS II Timing Analyzer to validate worst-case paths before tape-out.
The EPM5064JC1 commercial-grade JC suffix specifies 0-70°C operation. Estimated: at 5V VCC, all 64 macrocells switching at 50 MHz, ICC peaks around 150-200 mA, dissipating 0.75-1.0 W. With the 44-pin PLCC thermal resistance of approximately 40-50 C/W, junction temperature rise is 30-50°C above ambient at full toggle. For continuous high-temperature operation, derate by 50% macrocell utilization or migrate to MAX II EPM240 with lower ICC.
Compliance Information
Compliance data not provided in the Verified Web Data for EPM5064JC1. The MAX 5000 family predates the 2006 RoHS directive and many original variants are non-RoHS (SnPb finish); some distributor-stocked parts may be lead-free conversions. AEC-Q100 not applicable - this is a commercial-grade PLD (JC suffix = 0-70°C). For automotive applications, migrate to MAX II EPM240 with industrial temperature grade.
