EPM5192LC Overview
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell blocks with a centralized interconnect matrix. It sits in the broader hierarchy of programmable logic -> logic device -> digital semiconductor, between simple SPLDs/GALs and higher-density FPGAs. Unlike SRAM-based FPGAs that require a boot PROM, MAX 7000S CPLDs store their configuration in on-chip EPROM cells, so the bitstream is retained without external memory and the device is ready at power-up.
Key features of the EPM5192LC include 192 macrocells organized as 16 macrocells per LAB, per-macrocell programmable register/feedback paths, JTAG (IEEE 1149.1) boundary-scan support, individual macrocell clock-enable and clear controls, and a shared input/clock architecture that routes every I/O pin to the global clock network. The PIA provides deterministic, predictable interconnect delays independent of logic placement, a hallmark of CPLD timing behavior.
Architecturally, the EPM5192LC uses Altera's classic MAX 7000S EPROM cell plus EEPROM-based configuration scheme, where each macrocell contains a product-term array feeding a programmable register that can be configured as D, T, JK, or SR flip-flop. Per-macrocell product-term allocation and the PIA's fixed-delay routing make timing closure straightforward: every logic path through the device has a known worst-case delay budget. Programming is performed via the Altera ByteBlaster or compatible JTAG programmer using the MAX+PLUS II or Quartus design flow.
Typical applications include legacy 5V glue logic replacement, industrial control state machines, address decoding for microprocessor/microcontroller buses, bus-interface adapters between asynchronous logic domains, and pin-compatible upgrades of older 28- to 192-macrocell designs. The OTP/EPROM architecture makes the part particularly suited to long-lifecycle industrial and mil-aero programs where in-system bitstream updates are not required.
When designing with the EPM5192LC, allocate macrocell product-terms carefully: each macrocell supports up to five product terms directly, with parallel expanders available for wider functions. Decoupling must follow the MAX 7000S reference design - one 0.1uF ceramic per VCC pin and a 10uF bulk capacitor close to the package. Unused I/O pins should be left floating or tied to a defined logic level through JTAG-driven output-enable control, and the global CLR and OE signals should be considered part of the functional logic budget rather than always-on signals.

Typical Applications
EPM5192LC is suitable for 6 applications: Legacy 5V Glue Logic Replacement, Industrial Control State Machines, Microprocessor Bus Address Decoding, Bus-Interface Adapter Between Logic Domains, Legacy Pin-Compatible Upgrades (28-192 macrocells), Mil-Aero Long-Lifecycle Embedded Logic.
Legacy 5V Glue Logic Replacement
The EPM5192LC is a strong fit for replacing multiple discrete 5V TTL/CMOS glue-logic ICs - address decoders, bus arbiters, and interrupt controllers - because its 192 macrocells can absorb 20 to 50 small PAL/GAL-equivalent functions on a single 5V device. Its non-volatile EPROM configuration means the board is active at power-up with no boot PROM, unlike SRAM-based FPGAs that need an external configuration memory. The 64 user I/O pins give generous headroom for 8/16-bit microprocessor bus interfaces, and the 55 ns tPD keeps decoding well within one 25 MHz memory cycle. Designers should budget macrocell product-terms (5 per macrocell natively, expandable via parallel expanders) when consolidating wide AND-OR decoders.
Recommended
Industrial Control State Machines
The EPM5192LC is well-suited to industrial control state machines because its deterministic PIA routing gives fixed worst-case delays regardless of placement, simplifying timing closure for safety-critical control loops. With 192 macrocells the device can hold a 20-30 state FSM plus encoder, watchdog, and diagnostic logic in one IC, and the 5V tolerance matches legacy PLC backplanes and 24V-isolated sensor interfaces. The -40C to +85C industrial variants (EPM5192GM/883B screened parts) extend operation to harsher environments. The MAX+PLUS II or Quartus design flow supports state-machine entry with Verilog/VHDL, and JTAG boundary-scan allows in-system test access for cabinet-level diagnostics.
Recommended
Microprocessor Bus Address Decoding
For 16- and 32-bit microprocessor address decoding, the EPM5192LC's 192 macrocells can implement chip-select logic for 8-16 memory or peripheral banks plus wait-state generators, all on a single 5V device. The 64 I/O pins comfortably handle 24-bit address plus 8-bit data bus plus control signals, and the 55 ns typical tPD fits comfortably below one 25 MHz 68000- or 8086-class memory cycle. The JTAG port doubles as an in-system programming path and a boundary-scan test resource, useful when validating board-level interconnect. Designers should use the dedicated global clock and global CLR/OE pins to keep critical control signals jitter-free across all LABs.
Recommended
Bus-Interface Adapter Between Logic Domains
The EPM5192LC fits bus-interface adapter roles between asynchronous 5V logic domains because it offers independently configurable I/O pins and per-macrocell flip-flop clock selection, allowing two clocks to coexist in one device. With 192 macrocells it can implement a full 16-bit to 32-bit bridge with FIFOs implemented in distributed RAM (via macrocell feedback) and handshaking logic. The 5V-tolerant I/Os match TTL/CMOS peripherals, and JTAG enables in-system observability for protocol debug. The trade-off versus a modern FPGA is density: designs exceeding ~192 macrocells should migrate to MAX 7000S higher-density members or MAX II devices.
Recommended
Legacy Pin-Compatible Upgrades (28-192 macrocells)
The EPM5192LC is the natural drop-in upgrade path for older MAX 7000S designs built around 28-, 64-, 96-, or 128-macrocell parts, because it shares the same MAX 7000S architecture, JTAG flow, and 5V supply. Designers can recompile their MAX+PLUS II or Quartus project against the EPM5192LC device library and obtain a bitstream that loads into the larger device with no PCB changes. The 64 user I/O pins provide generous margin for additional logic, and the 192-macrocell capacity absorbs growth as product features evolve. The LC suffix denotes a windowed ceramic package for prototyping and reprogramming cycles.
Recommended
Mil-Aero Long-Lifecycle Embedded Logic
The EPM5192LC is well-suited to mil-aero embedded-logic applications because its UV-erasable ceramic package supports multiple design revisions, and the MAX 7000S architecture has decades of flight heritage. Programs that require long-term availability benefit from the existing inventory ecosystem of independent distributors, and the MIL-STD-883 variants (EPM5192GM/883B family) provide the temperature and screening headroom needed for defense and aerospace. The 5V supply rails match legacy avionics buses, and the deterministic CPLD timing simplifies worst-case timing analysis for safety-critical functions. Where smaller logic capacity is acceptable, the EPM5064 and EPM5032 LC variants extend the same architectural benefits to lower-density designs.

Key Differentiators
- Windowed ceramic package for repeated reprogramming (vs EPM5192JC (plastic, OTP))
- 192 macrocells in the same JLCC-68 footprint (vs EPM5128JC (128 macrocells, 64 I/O))
- Direct availability of military-screened siblings (vs EPM5192GM/883B (MIL-STD-883B variant))
Design Notes
Estimated: at 5V VCC and 50 MHz fMAX driving 64 CMOS inputs (each ~10uA static + 1mA dynamic), the EPM5192LC draws roughly 200-300 mA ICC. Place one 0.1uF ceramic decoupling capacitor adjacent to every VCC pin (typically 5-6 pins distributed around the JLCC-68 perimeter) and add a single 10uF tantalum or ceramic bulk capacitor within 25 mm of the package. The windowed ceramic LC package dissipates more heat than its plastic JC sibling; provide a continuous ground plane on the top or bottom layer to spread thermal load.
Route JTAG signals (TDI, TDO, TMS, TCK) with short traces kept clear of fast-edge I/O nets, and place a 10 kohm pull-up on TCK and TMS to keep the boundary-scan state machine in a defined state at power-up. The global clock input (CLK1) and global CLR/OE pins should be treated as critical nets - short, impedance-matched, and routed away from I/O that switches simultaneously. Ground the GND pins with a low-impedance via fan-out to the inner ground plane.
Do not assume the EPM5192LC is 3.3V tolerant: its I/O buffers are 5V CMOS and will be damaged by 3.3V logic signals applied without a level translator. Avoid mixing the EPM5192LC with the pin-compatible but lower-density EPM5128JC on the same PCB footprint without revalidating logic capacity - the bitstream is not portable across different macrocell counts. Finally, when migrating from the windowed LC to the plastic JC variant, confirm the JTAG programming algorithm matches because some early MAX+PLUS II flows required device-specific checksums.
The MAX 7000S PIA gives fixed routing delay independent of placement, simplifying timing closure but also meaning that long combinational paths should be registered before they consume too many LABs. Keep global clock and global OE fan-out to one NET (use the dedicated pin, not an I/O-emulated clock) and configure per-macrocell clock-enable rather than gating the global clock - this avoids skew on the clock distribution network. JTAG-driven output-enable is recommended for in-system test access to all 64 I/O pins.
Compliance Information
RoHS non-compliance is typical for legacy windowed-ceramic MAX 7000S packages that use lead-bearing ceramic and eutectic solder bumps; REACH compliance is per the manufacturer declaration. MIL-STD-883 variants (EPM5192GM/883B) are available for defense programs requiring extended temperature and screening.
