What is a MAX 5000 device? The Altera MAX (Multiple Array matriX) 5000 series is a classic UV-erasable/OTP Complex Programmable Logic Device (CPLD) family, sitting in the PLD hierarchy between simple PAL/GAL SPLDs and modern SRAM-based FPGAs. Architecturally, a MAX 5000 CPLD partitions logic into interconnected Logic Array Blocks (LABs), each containing a programmable AND/OR array feeding multiple macrocells with configurable flip-flops. Compared to a discrete PAL, a MAX 5000 CPLD provides higher density, predictable timing, and non-volatile (UV-erasable) configuration, while remaining far simpler than an FPGA - no external boot PROM, deterministic pin-to-pin delays, and a unified 5 V supply rail.
Key features of the EPM5192LI-2 include 192 macrocells organized into 12 LABs, 72 total inputs (7 dedicated + 64 I/O), 64 user I/O lines, 55 ns pin-to-pin propagation delay, and 100 MHz internal counter frequency. Power consumption is typically 600 mW at 5 V/25 C, and the device supports in-system programming via Altera's MAX+plus II design toolchain. The 84-pin PLCC (J-lead) package offers a socket-compatible upgrade path for legacy designs.
From an architectural standpoint, the EPM5192LI-2 uses Altera's classic EEPROM/UV configuration cell with a fast programmable interconnect (PIA) that routes signals between LABs. Each macrocell includes a product-term steering logic block, a programmable flip-flop (D/T/JK), and a user-configurable I/O architecture, giving the designer dense combinational plus registered logic without external glue. The -2 speed grade and the -LI (lower-power, industrial-temperature) suffix make this part well-suited for designs that previously used a 74-series TTL/SPLD combination but now require more logic per board.
Typical applications include industrial control glue logic, address decoding in microprocessor/DSP systems, bus interfacing (e.g., ISA, PC/104, VME), state-machine controllers, peripheral replacement, and legacy telecom backplane logic. The 192-macrocell density suits designs that previously required multiple PALs or discrete SSI/MSI logic.
When designing with the EPM5192LI-2, engineers should budget the device's worst-case Icc of approximately 600 mW and verify timing with MAX+plus II timing simulation, since the 55 ns tpd directly limits clock frequency at 18 MHz. The 84-pin PLCC package is windowed ceramic or OTP plastic; ensure your programmer supports the EPM5192 JEDEC file format.

典型應用
EPM5192LI-2 適用於 6 應用s: Industrial Control Glue Logic, Microprocessor / DSP Bus Address Decoding, Legacy ISA / PC/104 / VME Peripheral Interface, State-Machine and Protocol Controller, Telecom Backplane Logic Replacement, Industrial Test & Measurement Equipment.
Industrial Control Glue Logic
The EPM5192LI-2 is well-suited to industrial control glue-logic replacement, where its 192 macrocells and 64 I/O pins can absorb an entire board of 74-series TTL. With a 55 ns tpd and 100 MHz internal counter frequency, it handles address decoding, chip-select generation, and interrupt prioritization for 8/16-bit industrial microcontrollers (8051, 68k, x86). Its industrial -40 C to +85 C temperature range and 4.5 V-5.5 V supply match legacy PLC backplanes. Drop-in alternatives like EPM5192LC84-2 share the 84-pin PLCC footprint, allowing reuse of existing test fixtures.
推薦
Microprocessor / DSP Bus Address Decoding
In 16/32-bit microprocessor and DSP systems, the EPM5192LI-2 acts as a flexible address decoder and bus controller, replacing discrete GAL/PAL chips with a single CPLD. Its 7 dedicated inputs handle control signals like RD, WR, and chip-select enables, while 64 bidirectional I/O lines map memory-mapped peripherals onto the system bus. With 192 macrocells, designers can implement multi-bank chip-select logic, wait-state generators, and interrupt controllers in one device, while the 55 ns tpd ensures clean timing for 8-25 MHz system buses without metastability issues.
推薦
Legacy ISA / PC/104 / VME Peripheral Interface
The EPM5192LI-2 targets legacy peripheral interface cards where its 5 V supply, 84-pin PLCC package, and 64 I/O lines map directly onto ISA, PC/104, and VME bus signals. Its deterministic 55 ns propagation delay meets ISA's 8 MHz bus cycle budget and easily handles VMEbus DTB arbitration. The industrial temperature range and CMOS low-power (LI) suffix keep heat dissipation below 600 mW, important for sealed industrial enclosures. Field upgrades use the same PLCC socket, simplifying long-term maintenance.
推薦
State-Machine and Protocol Controller
For finite state machines and protocol controllers, the EPM5192LI-2 provides 192 macrocells with optional D/T/JK flip-flops per macrocell - ideal for implementing UART, SPI, I2C, and custom serial protocols in a single chip. The PIA interconnect delivers predictable tpd so state transitions remain deterministic across the 4.5-5.5 V supply range. Engineers use the CPLD to replace discrete 74LS/74HC sequencer ICs, saving PCB area while gaining reconfigurability through UV-erase or one-time-programmable windows.
推薦
Telecom Backplane Logic Replacement
The EPM5192LI-2 is widely deployed in backplane glue logic for legacy telecom equipment (T1/E1 multiplexers, channel banks, central-office line cards). Its 84-pin PLCC and 192 macrocells handle clock distribution, framing, alarm monitoring, and parallel-to-serial conversion without external boot memory. The 4.5-5.5 V supply aligns with telecom -48 V brick-derived 5 V rails. EPM5192LC84-2 offers a drop-in pin-compatible alternative when commercial-temperature environments are acceptable.
推薦
Industrial Test & Measurement Equipment
In bench-top instruments and ATE fixtures, the EPM5192LI-2 implements custom stimulus/response sequencers, timing generators, and parallel handshake controllers. Its 192 macrocells easily encode multi-channel pulse trains and trigger logic, while 64 I/O pins drive front-panel connectors and backplane buses. The PLCC package is socket-compatible for fast board swap during calibration cycles. Drop-in MAX 5000 family variants like EPM5192LC84-2 support production scaling with identical timing behavior.

主要差異化特點
- Industrial-temperature grade (LI suffix) for harsh environments (對比EPM5192LC84-2)
- -2 speed grade with 55 ns tpd verified at industrial temperature (對比EPM5192LI (no -2 suffix))
- Pin-compatible family of 192-macrocell devices on PLCC-84 (對比Discrete 74LS logic replacement)
設計說明
Estimated: At 5 V supply, room temperature, and typical CMOS switching activity, the EPM5192LI-2 draws approximately 600 mW (120 mA Icc) per the Altera MAX 5000 datasheet. Designers should budget at least 1 W of 5 V regulator headroom per device and use 0.1 uF ceramic bypass capacitors on every VCC/GND pair (pins 8, 21/33/56/79, 44, 68 per the package pinout) to suppress simultaneous-switching noise on the 64 I/O lines.
Because the EPM5192LI-2 has 64 I/O pins toggling concurrently, treat the device as a 64-channel synchronous switching source; place series resistors (22-33 ohm) on clocked outputs driving long PCB traces to dampen ringing. The MAX 5000 PIA interconnect adds a fixed routing delay to every LAB-to-LAB path - run MAX+plus II timing simulation to extract worst-case tpd before committing to high-frequency buses (above 25 MHz).
Do not confuse 'LI' (lower-power, industrial) with 'LC' (lower-power, commercial) - the temperature grade difference can cause field failures in uncontrolled environments. Always verify the JEDEC programming file matches the device suffix on the top mark. Programming the EPM5192LI-2 with an EPM5192LC JEDEC file may violate industrial spec. Use MAX+plus II's Device menu to confirm the selected device string before generating the .POF or .JED.
Place the EPM5192LI-2 PLCC socket near the center of the board with dedicated ground/power planes on adjacent layers; route the 7 dedicated inputs (pins 1-7) short and direct to avoid injecting noise into the global clock and clear networks. Keep high-current switching outputs on opposite sides of the package from analog-sensitive inputs. The PLCC J-lead socket accepts 84-pin through-hole footprints; ensure your PCB land pattern matches JEDEC MS-018.
