EPM5192LI84 - 192-Macrocell MAX 5000 CPLD 84-PLCC | Altera
MPN: EPM5192LI84 ✗ اختتامِ زندگیEPM5192LI84 جائزہ
A Complex Programmable Logic Device (CPLD) is a non-volatile, flash- or EPROM-based logic device that implements glue logic, state machines, bus decoding, and interface bridging functions between fixed-function ICs. The MAX 5000 family sits within Altera's broader programmable logic hierarchy: CPLD -> Programmable Logic Device (PLD) -> Programmable Logic -> Digital Semiconductor. CPLDs are distinguished from FPGAs by their deterministic timing, instant-on non-volatile configuration, and pin-to-pin delay specifications that do not vary with logic utilization.
Key features of the EPM5192LI84 include 192 macro cells, 3.75 K usable gates, 64 user I/O pins, a JTAG-based in-system programming interface (not all variants), and an OTP/UV-erasable configuration memory that retains pattern data without external storage. The PLCC-84 socket-compatible package is removable for laboratory UV erasure and re-programming, which historically made this family attractive for prototyping and low-volume industrial designs.
The device uses Altera's classic MAX architecture with an EEPROM/EPROM-based AND plane feeding a fixed OR-plane macro cell fabric. Each macro cell contains a programmable flip-flop, product-term selection logic, and an I/O control block. Logic synthesis is performed with Altera's MAX+PLUS II or Quartus design tools, which are still maintained in legacy mode for industrial customers servicing long-lifecycle equipment.
Typical applications include legacy industrial control replacement, military/aerospace avionics refresh (via the JM/883 MIL-STD-883B variants), telecommunications backplane glue logic, and bus-interface bridging in long-lifecycle OEM equipment. The OTP nature makes the EPM5192LI84 suited to designs where the pattern is finalized and re-programming is rarely required.
When designing with this part, note that the LI84 device does NOT support in-system programmability - the JTAG port is absent on most MAX 5000 OTP variants, so a stand-alone programmer (e.g. Altera Logic Programmer or compatible third-party tools) is required. Use the LC84 (windowed ceramic) variant if UV erasure is anticipated, and reserve proper decoupling on every VCC/ground pin pair to meet the 5 V TTL I/O switching noise budget.
This page synthesizes distributor pricing snapshots, same-brand pin-compatible variants already published on XAIPART (EPM5192LI family members), and practical design notes not found in the legacy Altera datasheet alone.

Legacy Industrial Glue Logic Replacement
The EPM5192LI84 is widely used to replace discrete 74LS/74F glue-logic ICs in long-lifecycle industrial control boards where the original programmable logic has failed after 20+ years of service. With 192 macro cells, 3,750 usable gates, and 64 user I/O pins, it absorbs the address decoding, chip-select generation, and handshake-stretching functions that previously required 8-15 discrete TTL packages. The OTP nature means the finalized pattern is fixed for the equipment's lifetime - ideal for OEM equipment that must remain bit-for-bit identical across decades of production. Engineers benefit from consolidating 74-series logic into a single 84-pin PLCC socketed part, simplifying board test and reducing assembly cost.

Telecommunications Backplane Bus Bridging
In legacy telecom backplanes (e.g. T1/E1 multiplexers, SDH/SONET tributary cards, central-office line cards), the EPM5192LI84 serves as a 5 V-TTL bus bridge between parallel processor buses and serial framer ICs. Its 25 ns pin-to-pin delay accommodates 40 MHz backplane operation without timing closure issues, and the deterministic delay model makes it suitable for asynchronous handshake protocols. The industrial temperature grade (-40 °C to +85 °C) and 5 V tolerance allow direct interface to legacy bus drivers like the AM26LS31/32 and DS26F31/32. The 84-pin PLCC socket allows field replacement without re-soldering, which is critical for telecom central-office maintenance windows.

Military/Avionics Refresh with MIL-STD-883B Variants
For avionics and defense refresh programs, the JM/883 and GM/883B screened versions of the EPM5192 share the same 84-pin PLCC pinout but add MIL-STD-883B processing for temperature, vibration, and hermeticity. The EPM5192LI84 itself is industrial-grade; designers seeking MIL-grade drop-in replacement can use EPM5192JM/883B or EPM5192GM/883B in the same PLCC-84 footprint. The 192-macrocell capacity suits mission-computer interface boards, MIL-STD-1553 bus monitor glue, and ARINC 429 line-card logic. PLCC packaging allows conformal coating and easy field replacement on avionics LRUs.

Bus Decoding and Chip-Select Generation
A primary application of the EPM5192LI84 is generating chip-select signals and address decoding for microprocessor memory maps. With 64 user I/O pins and 192 macro cells, the device can decode a full 24-bit address bus and generate up to 16-32 chip-select outputs with individual wait-state insertion. The OTP configuration makes it immune to soft errors and bus contention from mis-configuration, a frequent issue with flash-based CPLDs in noisy industrial environments. The 5 V TTL I/O matches legacy 80C186, 68SEC000, and 80C51 peripheral buses commonly found in factory automation and process control.

State Machine and Protocol Implementation
The EPM5192LI84 is well-suited to implementing synchronous state machines for serial protocols (SPI, I2C, UART bit-banging, custom proprietary protocols) in industrial equipment where dedicated peripheral ICs are unavailable. Each macro cell provides a D-flip-flop with individual clock-enable and clear, allowing complex FSMs with 50-80 states to be implemented cleanly. The deterministic 25 ns pin-to-pin delay ensures protocol timing margins are met across the full industrial temperature range. The PLCC socket allows post-assembly programming verification - the user programs the OTP, installs it, and verifies protocol operation in-system.

Long-Lifecycle OEM Production Sustainment
OEMs producing 15-30 year lifecycle equipment (medical imaging, semiconductor test gear, railway signaling, military radios) use the EPM5192LI84 because the OTP pattern guarantees bit-for-bit identical functionality across every unit ever shipped - no configuration drift, no flash bit-flip, no firmware-update risk. The Altera MAX 5000 datasheet guarantees 20-year data retention in OTP mode. Independent distributors (Jotrin, FPGAkey, Win Source) continue to stock the part for these sustainment programs. The 84-pin PLCC is socket-compatible across production runs, simplifying board rework and field upgrades.

ڈیزائن نوٹس
Estimated: The EPM5192LI84 draws approximately 200-400 mA from a single 5 V supply depending on toggle activity and I/O switching. Provide one 0.1 µF ceramic decoupling capacitor per VCC/GND pin pair (8 caps for the 84-pin PLCC) plus a single 10 µF bulk tantalum or electrolytic on the 5 V rail. Place the 0.1 µF caps within 3 mm of each VCC pin to suppress TTL switching transients. The device has no power-sequencing requirement relative to other 5 V logic, but ensure the 5 V rail ramps monotonically to avoid EEPROM cell stress during initial power-up programming.
Use a through-hole PLCC-84 socket (e.g. 3M 8484 or equivalent) so the OTP device can be programmed externally and replaced without de-soldering. Maintain 0.1 inch (2.54 mm) pitch land pattern with 1.0-1.5 mm drill pads for socket compatibility. Route all 64 user I/O signals with 50 Ω controlled impedance if any signal exceeds 25 MHz; otherwise standard TTL routing is sufficient. Keep the 84-pin PLCC socket away from board edges to avoid mechanical stress and provide at least 0.5 inch clearance on all sides for programming clip access.
Critical pitfalls: (1) The EPM5192LI84 is OTP - it cannot be re-programmed. Use the EPM5192LC84 (ceramic-windowed) variant for development and switch to LI84 only for production. (2) The LI84 has NO JTAG port - programming requires a stand-alone Altera Logic Programmer (e.g. PL-ASAP) BEFORE board installation or with a socket adapter. (3) Do not mix EPM5192 (MAX 5000, 5 V) with MAX 7000 (EEPROM, 5 V) or MAX V (1.8 V core) - pinouts are NOT compatible despite same PLCC-84 footprint. (4) Verify programming voltage timing on the stand-alone programmer; over-voltage on the OTP programming pins will permanently damage the device.

RoHS/REACH/lead-free status not stated in the Verified Web Data; pre-2005 Altera MAX 5000 OTP plastic parts were typically manufactured with SnPb finish (non-RoHS). For RoHS-compliant alternatives in the same footprint, contact Altera/Intel FPGA regarding lead-free re-finished inventory (rare for obsolete OTP parts).
