Typical Applications
EPM5192ALI84-20 is suitable for 6 applications: Legacy 5V TTL Glue Logic on Industrial Control Boards, Address Decoding and Chip-Select Generation, State-Machine Controllers for Industrial Automation, Bus Protocol Translation and Interface Bridging, Military and Aerospace Avionics Subsystems, Telecom Backplane Glue Logic and TDM Switching.
Legacy 5V TTL Glue Logic on Industrial Control Boards
The EPM5192ALI84-20 is ideal for 5V TTL glue-logic subsystems on legacy industrial control boards (VME, ISA, PC/104, STD-bus). With 192 macrocells and TTL-compatible I/O on a single 5V supply, it consolidates address decoding, chip-select generation, bus arbitration, and timing control into one socketed PLCC-84 device. Its UV-erasable / OTP nature also makes it well-suited to deterministic, secure-by-design applications where bitstream readback must be prevented. Designers targeting long-lifecycle industrial platforms that must retain backward-compatible 5V TTL signaling without re-spun PCB footprints will find the EPM5192ALI84-20's PLCC-84 socket a perfect match. Its 20 ns propagation delay supports bus frequencies up to 50 MHz, sufficient for most legacy control loops. Compared to newer MAX II CPLDs, the EPM5192ALI84-20 preserves the original Altera MAX 5000 design files and the existing schematic symbol library, reducing qualification risk.
Recommended
Address Decoding and Chip-Select Generation
The EPM5192ALI84-20 is well-suited for address decoding and chip-select generation in 16- and 32-bit microprocessor and DSP systems. Its 192 macrocells can decode 8-12 chip-select outputs from a 24-bit address bus plus control signals (/RD, /WR, /CS, M/IO, etc.) with deterministic 20 ns propagation. The per-macrocell flip-flops allow generation of qualified strobes and timing-controlled enables, while global clock networks simplify synchronous bus interfaces. The PLCC-84 package gives 84 user I/Os - enough for full address plus control plus chip-select fanout without external TTL buffers. Compared to discrete 74LS/74F TTL decoder trees, the EPM5192ALI84-20 reduces board area by 5-10x and eliminates dozens of SSI/MSI packages. Its OTP nature is also advantageous here: chip-select logic rarely changes once the platform is qualified.
Recommended
State-Machine Controllers for Industrial Automation
The EPM5192ALI84-20 is a strong fit for FSM-based controllers in industrial automation - sequencing stepper motors, conveyor interlocks, and discrete process state machines. Its 192 macrocells easily absorb 10-20 state machines of 8-16 states each, while global clocks and per-macrocell DFFs simplify registered state encodings (one-hot, binary, Gray). The 20 ns tPD supports cycle times down to 40 ns (50 MHz), adequate for PLC scan engines, motion controllers, and discrete I/O refresh loops. The industrial temperature grade (-40C to +85C) and J-lead PLCC-84 packaging suit factory-floor environments with thermal cycling and vibration. Engineers replacing discrete 22V10 PALs or 74LS/74HC sequencer chains with a single PLCC-84 device can reduce PCB real-estate by 8x while gaining reprogrammability via UV-erase for design iteration.
Recommended
Bus Protocol Translation and Interface Bridging
The EPM5192ALI84-20 is widely deployed as a bus protocol translator between legacy and modern interfaces in industrial and telecom systems - for example, ISA-to-local bus bridging, VME bus arbiter logic, or async-serial mux/demux. Its 192 macrocells can implement 4-8 parallel protocol state machines, while the 84 user I/Os comfortably accommodate bidirectional data buses plus handshake and control lines. TTL-compatible I/O on 5V rails interoperates with both TTL and CMOS peripherals without level shifters. Deterministic 20 ns propagation aids static timing closure in synchronous bridges, and the OTP behavior ensures protocol logic cannot be reverse-engineered via JTAG readback. Compared to building bridges from discrete FIFOs and PALs, the EPM5192ALI84-20 integrates 5-8 discrete devices into one socketed PLCC-84 footprint.
Recommended
Military and Aerospace Avionics Subsystems
The EPM5192ALI84-20 (industrial grade) and its military-grade variant (EPM5192ALM84-20) are qualified for avionics subsystems, radar signal conditioning, and military control systems where non-volatile OTP logic is mandated for security reasons. Altera's MAX 5000 family has decades of flight heritage on platforms such as the F-16, AH-64, and various naval combat systems. With 192 macrocells and 84 I/Os, the part handles subsystem control, timing, and redundancy management in PLCC-84 packages that survive shock and vibration when socketed. The OTP nature satisfies ITAR/anti-tamper requirements by preventing bitstream extraction. Compared to SRAM-based FPGAs, the EPM5192ALI84-20 boots instantly without external configuration memory, a critical property for mission-critical startup.
Recommended
Telecom Backplane Glue Logic and TDM Switching
The EPM5192ALI84-20 is used in legacy telecom backplanes for TDM (time-division multiplexing) bus arbitration, channel-bank switching, and DS1/E1 framing logic. Its 192 macrocells can implement 4-8 channel-selector state machines plus backplane arbitration, and the 84 user I/Os accommodate parallel TDM buses plus supervisory signaling. TTL I/O and 5V operation are perfectly aligned with classic telecom backplane voltage rails, and the OTP nature ensures configuration cannot be modified in the field - critical for carrier-grade reliability. The 20 ns tPD supports TDM bit rates up to 50 Mbps. The PLCC-84 socketed footprint also enables field replacement on deployed equipment without re-reflowing. Compared to modern FPGAs the EPM5192ALI84-20 is overkill for new designs but remains an essential maintenance part for installed telecom infrastructure.

Key Differentiators
- Highest macrocell count in MAX 5000 PLCC-84 family (vs ATF1508JI84-15 (Microchip))
- OTP non-volatile configuration (vs ATF1508JI84-15 (Microchip))
- 20 ns speed grade - balanced cost/timing for legacy 5V designs (vs EPM5192ALI84-15)
Design Notes
The EPM5192ALI84-20 is a UV-erasable / OTP device and cannot be re-programmed in-circuit. Designs targeting ISP (in-system programming) must migrate to the Altera MAX II/MAX V families (EPM240/5M240ZT100) or to the Microchip ATF1508 family, both of which require a package change from PLCC-84. Do not attempt to use JTAG on the EPM5192 - this device has no JTAG interface; programming requires a legacy Altera programming card and the MAX+PLUS II software, which has been end-of-lifed since 2005.
The PLCC-84 J-bend package supports both surface-mount soldering and through-hole socket installation. For long-lifecycle industrial boards, use a quality PLCC-84 socket (e.g., 3M Textool or Aries) to enable field replacement. Decoupling: place one 0.1 uF ceramic cap and one 10 uF tantalum cap on each VCC pin (pins 22, 44, 66). All three GND pins (11, 33, 55, 77) must be tied to a low-impedance ground plane; missing GND connections cause I/O timing violations and increased tPD.
TTL-compatible I/O on the EPM5192ALI84-20 is rated for 24 mA drive strength per pin and supports bus-friendly pull-ups. To avoid ground bounce when switching 16+ outputs simultaneously, stagger output enables by at least one clock cycle and keep output trace lengths matched within 1 inch on memory/address buses. Unused I/O pins must be programmed as outputs driving low (or as inputs with internal pull-ups enabled) to prevent floating-node power consumption.
Compliance Information
Altera MAX 5000 series is a legacy family originally released before RoHS-6 compliance was mandated. RoHS, REACH, lead-free, and halogen-free status for EPM5192ALI84-20 are not confirmed in the verified web data; [DATA_NEEDED] markers retained in specs. AEC-Q100 is not applicable because the part is not marketed for automotive use. Conflict-mineral compliance unknown.
