Typical Applications
EPM5064JI-1 is suitable for 6 applications: Legacy 5V Address Decoding, Industrial Glue Logic Replacement, VME/ISA Backplane Controllers, Retro Computing & Prototyping, Military/Aerospace Legacy Systems, Process Control & PLC I/O.
Legacy 5V Address Decoding
The EPM5064JI-1 fits legacy 5V address decoding applications because the MAX 5000 family operates from a single 5V supply and provides deterministic 15 ns combinational propagation delays across the 64 macrocells. Why this part: the deterministic tPD eliminates address-decode race conditions in 8086/VME/ISA bus systems where multiple cycles per instruction depend on stable decoder outputs. How used: typically placed between the CPU address bus and peripheral chip-select pins, replacing 2-3 packages of 74LS138/74LS139 decoders with one EPLD. Performance consideration: at 5V the CMOS inputs are TTL-compatible, allowing direct interface to legacy 5V logic without level shifters; however, the UV-erasable ceramic package increases per-unit cost relative to OTP alternatives.
Recommended
Industrial Glue Logic Replacement
The EPM5064JI-1 fits industrial glue-logic replacement because the MAX 5000 family integrates AND/OR array logic with user-programmable interconnect, replacing 4-8 packages of discrete 74LS TTL per board. Why this part: 64 macrocells with 100% interconnect utilization allow consolidation of counters, muxes, state machines, and chip-select logic into one device. How used: the EPLD is programmed with the MAX+PLUS II design flow (legacy Altera tool), then soldered into a 68-pin PLCC socket on the industrial controller PCB. Performance consideration: per the MAX 5000 datasheet, all macrocells feature identical fixed-delay interconnect, ensuring timing closure without manual place-and-route iterations - critical for industrial designs with deterministic scan-time requirements.
Recommended
VME/ISA Backplane Controllers
The EPM5064JI-1 fits VME/ISA backplane controller applications because the MAX 5000 EPLD provides 5V-tolerant CMOS I/O and predictable timing suitable for legacy bus arbitration and bus-master handshaking. Why this part: 64 macrocells accommodate typical bus-controller state machines, interrupt controllers, and bus-watchdog functions in a single 68-pin PLCC. How used: the EPLD interfaces to VME bus signals D16/D32 and BERR/SYSRESET, encoding bus-request grants and interrupt acknowledge cycles. Performance consideration: at typical 8-25 MHz bus speeds the 15-ns combinational delay is sufficient for one wait-state insertion; however, NRND status means design teams should validate long-term availability against 5-7 year product support windows.
Recommended
Retro Computing & Prototyping
The EPM5064JI-1 fits retro computing and prototyping applications because the UV-erasable windowed ceramic package allows iterative design changes during hobbyist or educational reproduction of vintage 8-bit and 16-bit systems. Why this part: the JI (windowed) variant supports dozens of erase/reprogram cycles via UV exposure, ideal for restoring or modifying legacy hardware such as CP/M systems, S-100 bus cards, or vintage arcade boards. How used: the EPLD replaces missing or damaged TTL logic on vintage PCBs, programmed via EPROM-style device programmers compatible with the MAX 5000 JEDEC file format. Performance consideration: at 5V supply the part integrates seamlessly with 74LS/74HC logic on legacy boards; designers should note that windowed ceramic packages are increasingly rare and command premium pricing on the secondary market.
Recommended
Military/Aerospace Legacy Systems
The EPM5064JI-1 fits military and aerospace legacy systems because the ceramic PLCC package offers improved thermal and mechanical reliability versus plastic, and the MAX 5000 EPLD is approved for many legacy MIL-spec platforms still in service. Why this part: windowed ceramic EPLDs have decades of flight heritage in avionics, radar, and missile-control systems that cannot be redesigned around modern CPLDs without recertification. How used: the EPLD replaces obsolete 54LS TTL series logic in ground support equipment, test fixtures, and depot-level repair of fielded systems. Performance consideration: per the MAX 5000 datasheet, ceramic packages operate across extended military temperature ranges when specified; however, the NRND status requires ongoing obsolescence management with franchised distributors.
Recommended
Process Control & PLC I/O
The EPM5064JI-1 fits process control and PLC I/O applications because the MAX 5000 EPLD provides deterministic 5V logic for industrial sensors, optocoupler interfaces, and discrete I/O conditioning. Why this part: 64 macrocells can implement encoder quadrature decoding, PWM generation for solenoid control, and isolated digital input filtering in a single device. How used: the EPLD sits between PLC backplane logic and field-side optocouplers, providing hardware-level debounce, pulse-stretch, and watchdog functions. Performance consideration: the 5V CMOS interface integrates directly with 24V-to-5V optocoupler outputs without level translation; however, for new PLC designs, modern MAX II or MAX V CPLDs offer lower power, smaller packages, and non-volatile configuration absent in the MAX 5000 UV-erasable architecture.

Key Differentiators
- UV-erasable windowed ceramic for iterative prototyping (vs EPM5064JC-1)
- 64 macrocells - mid-range of MAX 5000 family (vs EPM5032DC-25 (32 macrocells))
- Same die as production plastic variants (vs EPM5064JC-2)
Design Notes
The EPM5064JI-1 operates from a single 5V supply per the MAX 5000 datasheet. Decoupling requires a 0.1uF ceramic capacitor placed as close as possible to each VCC/GND pair on the 68-pin PLCC package. Add a bulk 10-47uF tantalum or aluminum electrolytic capacitor on the 5V rail near the EPLD to suppress switching transients when multiple macrocells toggle simultaneously during state-machine transitions.
Do not assume all MAX 5000 family members share the same package. The EPM5064JI-1 is a 68-pin PLCC; the EPM5032 variants come in 24/28-pin DIP/PLCC, and the EPM5128 uses an 84-pin PLCC. Verify pin-count and pinout against your PCB footprint before substituting across macrocell counts. For socketed designs, use a machined-pin PLCC socket rather than stamped contacts to ensure reliable UV-erase cycles.
The ceramic windowed PLCC package of the EPM5064JI-1 offers superior thermal performance versus plastic PLCC, but at 5V CMOS the device typically consumes less than 200mW active. No heatsink is required for normal commercial-temperature operation. For military-spec applications requiring -55C to +125C operation, derate I/O toggle frequency to ensure junction temperature stays below 150C, especially in sealed enclosures without airflow.
Route all 68 PLCC signals to allow access to the ceramic window if UV erasure is required for design iteration. Provide at least 5mm clearance above the package for the UV eraser lamp. For socketed designs, leave room for a 68-pin PLCC extraction tool. For surface-mount designs, use land patterns compliant with JEDEC MS-018 or equivalent PLCC-SMD footprint specifications.
Compliance Information
Compliance status not provided in Verified Web Data. NRND-era Altera ceramic-windowed EPLDs predate widespread RoHS documentation; assume non-compliant unless explicitly certified by Intel/Altera documentation.
