EPM5192AJC-25 概述
An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic device that combines AND/OR array architecture with macrocell-based output logic, falling within the broader hierarchy of programmable logic devices (PLD) -> EPLD/CPLD -> complex programmable logic. EPLDs sit between simple PAL/GAL devices and modern SRAM-based FPGAs in terms of density and are characterized by deterministic propagation delay that does not depend on routing path length - a critical property for asynchronous bus interfaces and decoder logic.
Key features include 192 macrocells organized into multiple Logic Array Blocks (LABs), 100% factory-tested operation, 5 V CMOS I/O with TTL-compatible inputs, programmable output macrocells with configurable flip-flops, and a maximum propagation delay of 25 ns (tPD). The ceramic windowed PLCC package supports UV erasure for prototype and development cycles, while the AJC suffix denotes the PLCC-68 ceramic windowed form factor with industrial-grade operating temperature range.
The MAX 5000 architecture uses a classic EPROM-based AND/OR plane feeding output macrocells with selectable registered/combinational modes. Unlike SRAM-based FPGAs, the device requires no external boot PROM, powers up in a defined state, and retains configuration indefinitely. The 25 ns speed grade positions this part for legacy 25-33 MHz bus interfaces rather than modern high-speed designs.
Typical applications include legacy PC/AT bus decode logic, peripheral controllers (DMA, interrupt, bus arbitration), industrial state machines, military/aerospace systems (the J-grade marking indicates MIL-STD-883 processing), and prototyping platforms for newer MAX 7000/MAX II designs. Engineers working on long-lifecycle defense and aerospace equipment frequently retain MAX 5000 designs due to form-fit-function stability.
When designing with this EPLD, ensure the propagation delay budget accounts for both tPD and tCO (clock-to-output) timing - consult the datasheet for the exact derating curves at junction temperatures above 70°C. UV erasure requires a windowed ceramic package; production plastic-package equivalents (EPM5192AQI, EPM5192AQC) offer one-time programmable (OTP) replacements with identical footprint but no window.

典型应用
EPM5192AJC-25 适用于 6 应用s: Legacy PC/AT Bus Decode Logic, Industrial State Machine Control, DMA and Interrupt Controller Glue Logic, Military and Aerospace System Controllers, Peripheral Controller Integration, Prototype Development for Newer MAX CPLDs.
Legacy PC/AT Bus Decode Logic
The EPM5192AJC-25's deterministic 25 ns tPD and 192 macrocells make it well suited for PC/AT ISA bus address decoding and chip-select generation in legacy embedded motherboards. Its 5 V TTL-compatible inputs interface directly with ISA bus signals without external buffering, while the non-volatile EPROM-based configuration boots the system into a defined state on power-up without an external boot PROM - critical for cold-start boot ROM integration. The MAX 5000 deterministic timing eliminates the setup-time uncertainty that plagues SRAM-based FPGAs at fixed ISA bus frequencies (8.33 MHz).
推荐
Industrial State Machine Control
The EPM5192AJC-25 supports complex industrial state-machine implementation across 192 macrocells, with non-volatile EPROM configuration retaining the state-machine definition across power cycles without external memory. The MAX 5000 registered-logic capability with configurable flip-flop types (D, T, JK) enables Moore and Mealy machine implementation, while 5 V CMOS I/O interfaces directly with industrial 24 V sensor signal-conditioning circuits through standard buffers. Deterministic propagation delay ensures predictable state-transition timing critical for safety-interlock logic.
推荐
DMA and Interrupt Controller Glue Logic
The EPM5192AJC-25 integrates DMA handshake sequencing, interrupt priority encoding, and bus arbitration logic in a single 192-macrocell device, replacing 4-6 discrete 74-series TTL packages. The MAX 5000 LAB architecture supports parallel logic paths without routing delay penalties, ensuring that DMA acknowledge and bus-request signals propagate within fixed timing windows. Industrial-grade ceramic packaging delivers the thermal stability required for continuous-operation server-class systems.
推荐
Military and Aerospace System Controllers
The EPM5192AJC-25's ceramic windowed PLCC package and Altera's MIL-STD-883 processing make it suitable for military and aerospace flight-control, radar, and avionics subsystem integration. The non-volatile EPROM configuration survives single-event upset (SEU) conditions better than SRAM-based alternatives, and the deterministic 25 ns timing supports hard-real-time control loops. Long-form-fit-function lifecycle stability (MAX 5000 has been in production for over 25 years) is critical for defense programs requiring 20+ year support windows.
推荐
Peripheral Controller Integration
The EPM5192AJC-25 integrates multiple peripheral controller functions - SCSI bus arbitration, parallel-port handshaking, UART timing generation - into one device, reducing board area and BOM count versus discrete 74LS/74F TTL. Its 192 macrocells can implement 4-5 independent peripheral controllers with each consuming 30-40 macrocells. The MAX 5000 I/O flexibility supports bidirectional bus pins and open-drain emulation through output-macrocell configuration.
推荐
Prototype Development for Newer MAX CPLDs
The EPM5192AJC-25's UV-erasable windowed ceramic package makes it ideal as a prototype vehicle for developing MAX 7000 or MAX II designs that will transition to OTP plastic packages in production. Engineers can iterate design logic, verify timing closure at 25 ns, then re-target the proven HDL to MAX 7000A or MAX II CPLDs using the same Altera Quartus design flow. The PLCC-68 package provides a familiar socketed prototyping form factor for breadboard and evaluation-board use.

关键差异点
- UV-erasable windowed ceramic package enables prototype iteration （对比 EPM5192AGC-20)
- Slowest speed grade (25 ns) within MAX 5192 family （对比 EPM5192AJC-15)
- Largest density option in PLCC-68 MAX 5000 family （对比 EPM5064JC-2)
设计说明
Use a PLCC-68 through-hole or socketed footprint with at least 4 ground pins distributed around the package (pins 12, 24, 37, 49, 60 in the typical Altera MAX 5000 pinout) for low-impedance ground return paths. Decouple each VCC pin with a 0.1 uF ceramic capacitor placed within 5 mm of the package, plus a bulk 10 uF tantalum capacitor near the device. Keep high-speed output traces short and avoid routing them parallel to clock inputs to minimize crosstalk on the deterministic 25 ns timing window.
Do not substitute a windowed AJC package with a plastic-package AQC/QI variant without verifying the program file compatibility - plastic MAX 5000 parts are OTP and cannot be re-erased. When designing a new prototype, plan to migrate from AJC (UV-erasable) to AGC (OTP ceramic) or AQC (plastic OTP) once the design is finalized to reduce production cost. Verify date codes on legacy stock: MAX 5000 parts older than 15 years may exhibit EPROM charge loss - request factory refresh or fresh-from-stock components.
MAX 5000 EPLD outputs use 5 V CMOS levels with TTL-compatible inputs; series-terminate outputs with 33 ohm resistors when driving traces longer than 50 mm to control edge rates around 5 ns. The deterministic 25 ns tPD applies at 25 pF load - derate timing budget by approximately 0.5 ns per additional 50 pF of capacitive load. Use the Altera MAX+PLUS II design software (legacy) or Quartus II for new compilation to ensure timing closure across PVT variations.
