Typical Applications
EPM5192LC1 is suitable for 6 applications: 5V Industrial Backplane Glue Logic, Legacy Microprocessor Address Decoding, Asynchronous State Machines in Telecom & Instrumentation, Peripheral Interface Adapters (GPIB, SCSI, IEEE-488), Refresh / Replacement of End-of-Life MAX 5000 Designs, Embedded Control & Legacy Industrial PLC I/O.
5V Industrial Backplane Glue Logic
The EPM5192LC1's 192 macrocells and 64 I/O pins at 5V CMOS levels match legacy industrial backplane requirements where TTL-compatible signaling and deterministic timing are essential. The 40 ns tPD and 50 MHz fMAX comfortably handle bus decoding, interrupt steering, and chip-select generation for backplane cards. Its 7 dedicated inputs simplify clock/reset distribution without burning macrocell resources, while the PQCC84 footprint has been used in production backplanes for decades.
Recommended
Legacy Microprocessor Address Decoding
The EPM5192LC1 is well matched to address decoding for 8086, 68000, Z80, and similar legacy microprocessors, replacing multiple PAL/GAL devices with a single 192-macrocell CPLD. Its wide input fan-in via 7 dedicated pins plus 64 I/O accommodates full 20-24 bit address buses and 8-16 bit data-path control logic. Deterministic 40 ns propagation delay guarantees clean chip-select timing across read/write cycles without metastability risk in asynchronous designs.
Recommended
Asynchronous State Machines in Telecom & Instrumentation
Telecom and instrumentation front-ends rely on asynchronous state machines for protocol handling, line-interface control, and measurement sequencing where the EPM5192LC1's MAX 5000 fabric excels. The 50 MHz fMAX supports fast state transitions while the CMOS EPROM technology provides instant-on, non-volatile configuration that survives power loss. The 5 V supply and TTL I/O levels simplify interfacing with ECL-to-TTL translators and front-panel switch matrices.
Recommended
Peripheral Interface Adapters (GPIB, SCSI, IEEE-488)
The EPM5192LC1 implements byte-control and handshaking logic for legacy peripheral interfaces such as GPIB (IEEE-488), SCSI, and parallel port adapters. Its 192 macrocells handle full state machines for talker/listener arbitration, NRZ encoding, and REQ/ACK handshaking, while 64 I/O pins map cleanly to 8-bit data plus control nets. The 5 V TTL I/O and PQCC84 footprint match the original GPIB controller reference designs still in production today.
Recommended
Refresh / Replacement of End-of-Life MAX 5000 Designs
Many long-lifecycle aerospace, defense, and industrial programs still depend on the original MAX 5000 footprint, and the EPM5192LC1 is the pin-compatible OTP production part to keep those boards running. The PQCC84 land pattern, JEDEC S-PQCC-J84 outline, and 192-macrocell count are identical to the original qualification baseline. Where the LC1 plastic OTP variant is the production fit, the JC84-1 windowed ceramic variant supports the same footprint for field re-programming.
Recommended
Embedded Control & Legacy Industrial PLC I/O
The EPM5192LC1 supports embedded control blocks such as legacy PLC digital I/O expansion, encoder-counter decoding, and isolated relay-driver sequencing, where its 64 I/O pins interface directly to 5 V logic families and opto-isolators. The 192-macrocell capacity lets designers integrate scan-matrix, debounce, and PWM generation into one CPLD, eliminating multiple 22V10/16V8 PALs. The OTP plastic LC package is suitable for high-volume factory-floor production.

Key Differentiators
- 192 macrocells, largest in MAX 5000 family (vs EPM5064LC-1 (64 macrocells))
- 7 dedicated high-fan-in inputs (vs EPM5128JC-1 (128 macrocells, 4 dedicated inputs))
- Industry-standard PQCC84 footprint (vs EPM5192LC-2N (PQFP package))
Design Notes
Estimated: at 50 MHz with all 64 I/O toggling, the EPM5192LC1 draws roughly 200β300 mA from the 5 V supply (typical ICC at full logic activity). Place a bulk 10 Β΅F tantalum capacitor at the board 5 V entry, then one 0.1 Β΅F ceramic per VCC/GND pair within 5 mm of the PQCC84 leads to suppress VCC sag during simultaneous switching outputs. Use a 4-layer PCB with a dedicated ground plane; the high edge rates of 5 V CMOS outputs couple noise into VCC if decoupling is inadequate.
Route all seven dedicated inputs (GCLK, OE, CLR, and four additional dedicated pins) before any bidirectional I/O to keep clock and reset distribution paths short. Keep a continuous ground ring around the PQCC84 J-leads; via-fan the ground ring to the internal ground plane every 5 mm. Avoid running 5 V TTL signals parallel to clock traces for more than 25 mm to prevent crosstalk into the AND array, which directly impacts tPD and fMAX.
Estimated: floating I/O pins on the EPM5192LC1 may source or sink 1β2 mA each through input-protection diodes, potentially causing VCC droop. Always terminate unused I/O pins per datasheet (typically pull-up or pull-down to VCC/GND via 10 kΞ©) and configure unused macrocells to default low-power mode in MAX+PLUS II. Do not exceed 5.25 V on any I/O even momentarily; the EPROM programming algorithm requires a higher voltage on specific pins that must never be applied during normal operation.
Compliance Information
EPM5192LC1 is part of the legacy Altera MAX 5000 family, classified obsolete. RoHS, lead-free, halogen-free, REACH, and conflict-minerals status are not explicitly stated in the verified distributor data and should be requested from the supplier on a per-lot basis. For automotive programs, AEC-Q100 is not applicable; use the GM/883B military-grade variant instead.
