EPM5064LI Présentation
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that sits in the hierarchy between simple PAL/GAL devices and high-density FPGAs. CPLDs typically contain multiple macrocells with sum-of-products logic and a centralized interconnect fabric, providing fast, deterministic pin-to-pin propagation delays ideal for glue logic, bus decoding, and state-machine implementation. The MAX 5000 family was among the earliest commercially successful CPLD families, combining EPROM/EEPROM non-volatile configuration with predictable timing — a useful baseline for legacy industrial and telecom designs.
Key features of the EPM5064LI include 64 macrocells, 4 LABs, 28 I/O pins, 7 dedicated inputs, 33.3 MHz maximum frequency, 55 ns propagation delay, 4.5V to 5.5V single-supply operation, industrial temperature grading, and J-bend PLCC-44 terminals. The non-volatile UV-erasable (windowed) or one-time-programmable (OTP) configuration memory eliminates the need for an external boot PROM and ensures instant-on behavior on power-up. The MAX architecture provides 100% interconnect within and between LABs.
Technically, the EPM5064LI uses Altera's classic MAX architecture in which each macrocell contains a programmable AND/OR array feeding a configurable flip-flop with product-term steering. The 4 LABs share a global interconnect that provides 100% connectivity between any two macrocells, enabling highly flexible logic placement. The I/O structure is symmetrical, with 28 bidirectional pins that can be configured for input, output, or tri-state operation with independent output enable control.
Typical applications include legacy industrial control glue logic, address decoding for microprocessor systems, bus interface and protocol bridging, state-machine controllers, and replacement of discrete TTL/CMOS logic in long-life-cycle equipment. The industrial temperature grade makes the part suitable for factory automation and outdoor control cabinets.
When designing with this device, engineers should plan for the 55 ns propagation delay when computing critical timing margins and confirm the 5V supply requirement is compatible with surrounding logic. The PLCC-44 socket footprint simplifies prototyping and field replacement, which is important for legacy systems still in production.

Applications typiques
EPM5064LI convient pour 6 applications: Legacy Industrial Glue Logic, Microprocessor Bus Address Decoding, State-Machine and Protocol Controllers, Legacy Telecom Interface Cards, Test and Measurement Front-End Decoders, Long-Life-Cycle Replacement of Discontinued TTL Logic.
Legacy Industrial Glue Logic
The EPM5064LI's 64 macrocells and 33.3 MHz operating frequency make it well suited to replacing multiple discrete 74LS/74HC TTL gates in long-life industrial controllers. Its 55 ns propagation delay provides predictable timing for address decoding and chip-select generation around legacy microprocessors. With 28 I/O pins plus 7 dedicated inputs, the device can absorb an entire board of random logic, simplifying schematics and reducing the bill of materials in factory automation equipment. The industrial temperature grade and UV-erasable or OTP configuration ensure reliable operation across decades of service.
Recommandé
Microprocessor Bus Address Decoding
Engineers use the EPM5064LI to decode 16- or 20-bit address buses into chip-select signals for memory and peripherals. Its non-volatile configuration eliminates the boot PROM required by SRAM-based FPGAs, and the 36-input capacity (28 I/O plus 7 dedicated) easily accommodates address plus control-signal fan-in. The 55 ns propagation delay is acceptable for asynchronous memory interfaces running at industrial-clock speeds, and the PLCC-44 socketed package simplifies field serviceability on legacy boards.
Recommandé
State-Machine and Protocol Controllers
With 64 macrocells the EPM5064LI can implement multi-state controllers for serial protocols, motor-control sequencing, or instrumentation timing. The deterministic 55 ns tPD allows precise state-machine timing without relying on internal clock dividers, and the JTAG-friendly MAX architecture simplifies verification. Industrial temperature grading and a robust CMOS 1-micron process make the part a reliable choice for outdoor telecom and energy-monitoring equipment that must operate unattended for years.
Recommandé
Legacy Telecom Interface Cards
Telecom shelf equipment manufactured in the 1990s often relies on MAX 5000 CPLDs for alarm monitoring, line-interface control, and bus arbitration. The EPM5064LI's 28 I/O pins suit 8-bit parallel data buses plus framing and clock signals, and the 4.5V to 5.5V supply matches the legacy 5V backplane. The non-volatile configuration means cards boot into a known good state without external configuration memory - critical for carrier-grade reliability and field replacement logistics.
Recommandé
Test and Measurement Front-End Decoders
Bench instruments such as logic analyzers and protocol testers use CPLDs to decode bus traffic into display or trigger signals. The EPM5064LI provides enough logic capacity for multi-channel parallel decoding and offers deterministic timing that aligns with sampled-data acquisition paths. Its 5V I/O compatibility simplifies interfacing with legacy ECL or TTL probe front ends, and the PLCC-44 package is easy to socket during calibration and firmware-revision changes.
Recommandé
Long-Life-Cycle Replacement of Discontinued TTL Logic
Many military, aerospace, and medical systems originally built with discrete TTL still require spare parts decades later. The EPM5064LI can replicate dozens of 74-series logic functions in a single PLCC-44 package, simplifying spares inventory and reducing board area in refurbishment programs. The OTP configuration option allows one-time programming for production runs, while the UV-erasable windowed variants support field re-programming during prototype rework.

Principaux différenciateurs
- Industrial temperature grade in the same PLCC-44 footprint (vs EPM5064LC)
- Maximum logic capacity in the EPM5064 family (vs EPM5032 / EPM5016)
- Non-volatile UV-erasable/OTP configuration (vs EPM240T100C5N (MAX II))
- 5 V I/O compatibility for legacy backplanes (vs EPM240T100C5N (MAX II))
Notes de conception
The EPM5064LI requires a single 4.75 V to 5.25 V supply (per the MAX 5000 datasheet, 4.5 V to 5.5 V is the absolute range). Place a 0.1 uF decoupling capacitor close to each VCC pin (pins 22 and 42) and a bulk 10 uF to 47 uF tantalum or aluminum electrolytic capacitor at the board supply input. Programmed MAX 5000 devices draw tens of milliamps in operation; verify the regulator has adequate headroom above the worst-case load.
The PLCC-44 (QCCJ) package uses J-leads on all four sides with pin 1 at the chamfered corner. Provide a PLCC-44 socket for prototype and field-replaceable designs to simplify rework. Maintain at least 0.5 mm clearance between the package outline and adjacent traces to prevent solder-bridging during reflow.
When migrating between EPM5064LI temperature or speed grades, confirm the timing model is unchanged: all -1, -2, and unsuffixed variants share the 55 ns tPD baseline per the MAX 5000 datasheet, but commercial-grade LC variants must not be used in industrial temperature environments. UV-erasable windowed parts (JC variants) require a quartz window in the package and a UV eraser for reprogramming.
Estimated: with 28 bidirectional I/O pins switching simultaneously, budget 4 mA per pin DC and verify the VCC pin inductance does not exceed 0.5 nH to keep supply bounce under 100 mV. Add 0.1 uF bypass capacitors adjacent to every four I/O pins to control ground bounce on fast edges.
Informations de conformité
EPM5064LI is a legacy Altera CPLD predating widespread RoHS adoption for PLCC-packaged logic. RoHS, REACH, lead-free, and halogen-free statuses are not confirmed in the verified data and are marked 'unknown' - confirm with the distributor at order time. AEC-Q100 is not applicable (the part is not marketed for automotive use).
