Safe Operating Area (SOA) & Thermal Characteristics
No official SOA curve available for this digital IC. Always operate within absolute maximum ratings specified in the datasheet. Ensure adequate cooling and derate as needed.
Typical Applications
EPM5192AQC100-20 is suitable for 6 applications: Legacy Microprocessor Address Decoding, Bus Interface and Arbitration Logic, Industrial State-Machine Controllers, DSP Peripheral Glue Logic, Legacy Communication Equipment Support, Test and Measurement Instrument Repair.
Legacy Microprocessor Address Decoding
The EPM5192AQC100-20 fits legacy address decoding applications where deterministic timing is mandatory. Its 192 macrocells can decode wide address buses (24-32 bits) and generate multiple chip-select outputs for memory banks and peripherals in 8086/80286/80386-era or Motorola 68000 systems. The 33 ns worst-case propagation delay fits within typical memory access time budgets of 80-120 ns, ensuring glitch-free chip-select assertion before data is sampled. Compared to discrete 74LS/74F-series decoder gates, the CPLD replaces dozens of SSI/MSI packages with a single device, reducing PCB area and improving reliability. The PQFP-100 footprint and 5V supply make it a direct pin-compatible replacement in legacy designs where board rework must be avoided.
Recommended
Bus Interface and Arbitration Logic
The EPM5192AQC100-20 is well suited to bus interface glue logic, including ISA, VME, and PCI-style bus bridges, where it can implement wait-state generators, byte-swapping multiplexers, and interrupt arbiters. The 192-macrocell capacity supports multi-master arbitration trees with priority encoders, bus-request/grant handshaking, and parity generation - all in a single device. The high-drive PQFP-100 outputs can directly drive TTL and CMOS bus loads without external buffers. Its 33 ns tpd suits asynchronous bus protocols where setup and hold margins must be predictable across temperature. Engineers maintaining legacy industrial bus systems use this part to consolidate discrete arbitration logic onto one CPLD.
Recommended
Industrial State-Machine Controllers
The EPM5192AQC100-20 is a strong fit for industrial state-machine controllers in factory automation and process control equipment. With 192 macrocells, designers can implement multi-state control sequences, timer/counter modules, and protocol converters (e.g., RS-232 to RS-485 framing) in one deterministic-logic fabric. The MAX 5000 family's synchronous clocking architecture and uniform interconnect delay simplify state-machine timing closure. Its PQFP-100 industrial-grade footprint supports conformal-coated board assemblies. Because the part is obsolete as of 2026-09-12, long-term maintenance teams are advised to stock this part for legacy equipment spares.
Recommended
DSP Peripheral Glue Logic
The EPM5192AQC100-20 historically interfaced TMS320, ADSP-21xx, and Motorola 56000 DSPs as peripheral glue logic. Its 192 macrocells handle wait-state generation, memory-bank selection, host-port arbitration, and serial-port routing around the DSP core. The 33 ns propagation delay aligns with DSP cycle times of 50-100 ns in legacy designs, allowing register-to-register glue logic to complete within one instruction cycle. The PQFP-100 footprint pairs well with through-hole or socketed DSP boards used in audio processing and motor control. Modern replacements exist in the MAX V family for new designs.
Recommended
Legacy Communication Equipment Support
The EPM5192AQC100-20 is used in legacy telecom and datacom equipment for protocol conversion, framing, and clock-recovery glue logic. Its 192 macrocells can implement HDLC framers, UART expansions, and timing-recovery sequencers around older framers and transceivers. The deterministic 33 ns tpd supports synchronous T1/E1-style line rates where setup and hold margins on data strobes are tight. The PQFP-100 footprint is commonly seen on legacy line-card assemblies. Maintenance teams keep the EPM5192AQC100-20 in stock for board-level repair of installed-base equipment, since redesign is rarely economical.
Recommended
Test and Measurement Instrument Repair
The EPM5192AQC100-20 is found in legacy oscilloscopes, logic analyzers, and bench instruments where it serves as central control logic, sequencing engine, and display multiplexer driver. Its 192 macrocells manage front-panel key scanning, A/D trigger timing, and channel-switching matrices in instruments built in the 1990s. The PQFP-100 package and 5V operation match the analog front-end rails typical of that era. Calibration and repair houses source the EPM5192AQC100-20 as a board-level replacement part to keep installed instruments operational without requiring complete redesign of the digital control section.

- Higher macrocell density than 5V peers (vs EPM5064LC)
Design Notes
The PQFP-100 package has a 0.65 mm terminal pitch and 100 gull-wing leads on all four sides. To achieve reliable reflow soldering, use a land pattern per IPC-7351 (PQFP, 0.65 mm pitch, 100 leads) with a solder mask defined pad of approximately 0.30 mm width. Maintain at least 0.20 mm clearance between adjacent pads and ensure the PCB pad plating is ENIG or immersion tin for best wetting. For prototype and low-volume builds, consider a machined-pin socket to allow device removal and reuse, especially given the part's obsolete status.
Because the EPM5192AQC100-20 is UV-erasable/OTP, a programming failure means the device is scrap unless you ordered a windowed ceramic variant. Always pre-verify the JEDEC fuse map with a logic simulation run before burning the device. JTAG pins TDI/TDO/TMS/TCK must be brought to a test header for in-circuit programming and board-level diagnostics; if these pins are left inaccessible, field updates are impossible. Also confirm the supply is 5V (the MAX 5000 family is not 3.3V tolerant) - applying 3.3V will not program the device reliably.
Place decoupling capacitors (0.1 uF ceramic in parallel with 10 uF tantalum or ceramic bulk) within 3 mm of every VCC/GND pair on the EPM5192AQC100-20. The MAX 5000 family has multiple VCC and GND pins distributed around the package; each pair must be locally decoupled to suppress switching noise. Route high-speed outputs (clocks, chip-selects) on the inner layers with a continuous ground return path beneath them, and avoid running outputs parallel to clock inputs to prevent crosstalk into the programmable interconnect matrix.
Compliance Information
Compliance information for EPM5192AQC100-20 was not present in the verified web data; the legacy PQFP-100 package from this era was typically non-RoHS (SnPb lead finish). Confirm with the supplier for current RoHS/REACH status.
