EPM5192ALM84-20 Présentation
What is a Complex PLD? A Complex Programmable Logic Device (CPLD) is a non-volatile digital logic IC that combines multiple PAL-like macrocell blocks on a single die with a programmable interconnect matrix. Each macrocell contains an AND/OR array feeding a flip-flop, and the entire device is configured by on-chip EPROM or EEPROM cells. CPLDs sit hierarchically between simple SPLDs (PAL/GAL) and FPGAs - they offer lower density than FPGAs but provide deterministic pin-to-pin timing (no routing variability), instant-on configuration, and high drive strength, making them ideal for bus decoding, power-up control, and high-speed control logic.
The EPM5192ALM84-20 features an output voltage swing compatible with 5V TTL logic, a programmable security bit for design protection, and a windowless/OTP switch-matrix architecture per the MAX 5000 datasheet. The "ALM84" suffix denotes the 84-pin PLCC package, while "-20" indicates the speed grade (approximately 33 ns propagation delay, tPD). All configuration is stored in EPROM cells - the device is one-time-programmable (OTP) in this package variant since there is no UV window for erasure.
Typical applications include TTL/CMOS logic integration, bus-interface controllers, address decoding and chip-select generation, state-machine implementation, and peripheral glue logic for legacy industrial and telecom systems. Because the part is UV-erasable only without a window, it is best suited for production volumes where field reprogramming is not required.
When designing with this device, observe the 33 ns worst-case tPD and derate timing for output enable and clock-to-output delays. The PLCC-84 socket allows easy prototype replacement but requires careful ESD handling. Power sequencing is not required - the device powers up with all outputs in a defined state per the MAX 5000 datasheet.

Applications typiques
EPM5192ALM84-20 convient pour 7 applications: TTL/CMOS Bus Glue Logic Integration, Address Decoding and Chip-Select Generation, State-Machine Replacement and Control Logic, Legacy Telecom Backplane Interface Logic, Peripheral Chip-Select and Interrupt Controller, Industrial Control and Test Equipment, Legacy Avionics and Defense Replacement Stock.
TTL/CMOS Bus Glue Logic Integration
The EPM5192ALM84-20 is well-suited for replacing dozens of 74-series TTL/CMOS glue-logic packages with a single CPLD. Its 192 macrocells can absorb wide address decoders, chip-select generators, and bus arbitration logic that would otherwise consume 15-25 discrete gates. The 33 ns tPD and 66.7 MHz fMAX comfortably meet ISA, PCI, and VMEbus timing, while 5V TTL-compatible I/O interfaces directly with legacy bus transceivers without level shifters. Programmable security bit prevents IP reverse-engineering, important for OEM designs.
Recommandé
Address Decoding and Chip-Select Generation
With 192 macrocells, the EPM5192ALM84-20 can decode wide address buses (24-32 bits) and generate chip-select signals for memory banks, peripherals, and I/O devices in microcontroller or microprocessor systems. The deterministic 33 ns propagation delay and 5V TTL outputs ensure clean CS timing without glitches. Designers typically combine multiple 8-bit address comparators and PAL equations in a single EPM5192, replacing 4-6 dedicated address decoder PALs and saving PCB area, cost, and inventory SKUs in industrial controller designs.
Recommandé
State-Machine Replacement and Control Logic
The EPM5192ALM84-20's macrocell architecture, where each cell contains a flip-flop, AND/OR array, and output enable, makes it ideal for implementing complex multi-state controllers (Mealy/Moore machines) in industrial automation and instrumentation. A single EPM5192 can hold 20-40 state variables and dozens of transition equations, far exceeding typical discrete PAL/GAL designs. The 66.7 MHz fMAX supports real-time control loops and high-speed protocol state machines such as custom serial interfaces, while 5V I/O drives opto-isolated industrial inputs directly.
Recommandé
Legacy Telecom Backplane Interface Logic
Telecom backplanes often require TTL-level bus arbitration, time-slot switching, and alarm monitoring logic that maps naturally onto the EPM5192ALM84-20's 64 user I/O and 192 macrocells. The 5V TTL compatibility interfaces directly with legacy line cards and backplane transceivers (e.g., DS26C31/DS26C32), and the 33 ns tPD meets the timing requirements of T1/E1 framing circuits and HDLC controller glue. The OTP nature provides design security against unauthorized cloning of OEM telecom equipment.
Recommandé
Peripheral Chip-Select and Interrupt Controller
The EPM5192ALM84-20 excels at consolidating peripheral interface glue: decoding memory-mapped registers for UARTs, timers, DMA controllers, and generating cascaded interrupt vectors for 8259-style interrupt controllers in x86 and 68k systems. With 71 total input lines (64 I/O + 7 dedicated), the device can monitor numerous interrupt request lines and bus status signals. Deterministic timing simplifies interrupt latency analysis, and 5V TTL I/O matches legacy peripheral chipsets without level translation.
Recommandé
Industrial Control and Test Equipment
Industrial test systems, ATE platforms, and process-control equipment benefit from the EPM5192ALM84-20's combination of high macrocell count, 5V TTL I/O, and deterministic timing. The 84-pin PLCC package allows socketed prototyping for firmware iteration during test-system development, and the OTP configuration secures proprietary test patterns and timing sequences. With 64 user I/O, the part can directly interface to relay drivers, optocouplers, and front-panel switches used in benchtop and rack-mounted test instruments.
Recommandé
Legacy Avionics and Defense Replacement Stock
Although EPM5192ALM84-20 itself is commercial-grade, the MAX 5000 family includes military-temperature variants (e.g., EPM5192AQC, EPM5192AGC) used in legacy avionics, radar, and weapons-system platforms with multi-decade field life. For these systems, the EPM5192ALM84-20 functions as a development prototype part on the bench, while the ceramic-windowed military variants are programmed and qualified for flight hardware. The 33 ns tPD and CMOS low power suit avionics EMI/EMC constraints, and the EPROM configuration is radiation-tolerant by design.

Notes de conception
The EPM5192ALM84-20 requires a single +5V supply on pins 21, 42, and 63, with ground on pins 9, 30, 53, and 74. Decouple each VCC pin with a 0.1 uF ceramic capacitor placed within 5 mm of the package pin, plus a bulk 10-47 uF tantalum or aluminum capacitor near the supply entry. Standard CMOS variants draw significant dynamic current during simultaneous output switching - estimate ICCCMOS using Icc = Icc_static + N x C x Vcc x f; for 192 macrocells switching at 10 MHz into 50 pF loads, dynamic current can exceed 200 mA.
The 84-pin PLCC package has a theta_JA of approximately 35-45 C/W in still air, which limits continuous power dissipation. For the standard CMOS variant ('L' suffix, not 'LC'), worst-case power dissipation with all outputs switching at maximum toggle rate can reach 1.5-2 W. In enclosed or high-temperature environments, switch to the 'LC' (low-power CMOS) variant or provide forced airflow. Always derate the junction temperature to keep Tj below 125C for commercial or 150C for industrial grades.
Use a PLCC-84 socket (e.g., 3M Textool or Yamaichi) for prototype development since the EPM5192ALM84-20 is OTP and cannot be erased in this windowless package. Place the socket with pin 1 aligned to the silk-screen dot. Provide 0.1 uF decoupling on every VCC pin and route all GND pins to a low-impedance ground plane. Keep clock inputs (dedicated input pins 75-81) short and shielded to minimize skew and noise pickup, since these feed the global clock distribution network.
Three common pitfalls: (1) Do NOT assume unused I/O pins default to a safe state - configure them as outputs driving logic-low or high-impedance inputs with internal pull-ups to prevent oscillation. (2) The 'L' suffix in 'LM84' indicates a windowless package - this is OTP only; for development use the ceramic-windowed 'G' variant (EPM5192AGC). (3) When migrating from a -20 to -15 speed grade, verify setup/hold margins in your design - the 8 ns improvement in tPD can shift timing relationships in cascaded logic paths and cause metastability at clock-domain crossings.
Route all 7 dedicated inputs (pins 75-81) with matched trace lengths if they are used as a synchronous bus (e.g., global clock and synchronous enables). One of these pins serves as the global clock for all macrocell flip-flops - skew here directly reduces fMAX. Keep TTL bus traces short and series-terminate if trace length exceeds 50 mm to control 5V TTL edge rates (~2 ns). Group outputs by drive direction to simplify PCB routing and reduce layer crossings.
