What is a CPLD? A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic IC that contains multiple PAL-like macrocell arrays interconnected by a central programmable switch matrix. CPLDs sit in the programmable logic hierarchy above simple PLDs (PALs/GALs) and below FPGAs, providing deterministic pin-to-pin timing, fast combinational logic, and instant-on behavior - making them ideal for glue logic, bus interfacing, and state-machine decoding. The EPM5192LC-25 is a member of the high-density MAX 5000 sub-family, which scales up the classic MAX architecture to 192 macrocells and large I/O counts.
Key features include 192 logic macrocells, a 25 ns worst-case pin-to-pin propagation delay (tPD), high-speed I/O with TTL-compatible thresholds, and built-in JTAG-based in-system programming via the MAX+PLUS II toolchain (legacy Altera software). The device is non-volatile, retaining its configuration without external memory, and the LC suffix indicates a ceramic JLCC package rated for commercial temperature operation with UV-erasable window capability for development and re-programming cycles.
Architecturally, the EPM5192LC-25 employs Altera's classic MAX Logic Element Array (LEA) fabric with a global programmable interconnect, dedicated input registers, and I/O control blocks that support configurable slew rates and pull-ups. The 25 ns speed grade reflects the worst-case commercial-spec timing over the full operating range, sufficient for many bus-interface and decoder applications in the 30-40 MHz logic-rate envelope.
Typical applications include legacy bus-interface glue logic (ISA, VME, PCI bridges), address decoding and chip-select generation, state-machine controllers for industrial control, peripheral I/O expansion, and migration targets for obsolete bipolar PAL devices. The UV-erasable window makes it suitable for prototyping, while OTP-mode production units are used for deployed systems.
When designing with this device, confirm that the 25 ns tPD satisfies the setup-time budget of the downstream logic. For new designs, modern MAX II/MAX V CPLDs are recommended; the EPM5192LC-25 is primarily sourced for legacy maintenance, repair, and military programs requiring the original MAX 5000 silicon.

Aplikasi Umum
EPM5192LC-25 cocok untuk 6 aplikasis: Legacy Bus-Interface Glue Logic, Address Decoding and Chip-Select Generation, Industrial State-Machine Controllers, Peripheral I/O Expansion and Port Multiplexing, Obsolete Bipolar PAL Replacement, Military and Aerospace Maintenance Programs.
Legacy Bus-Interface Glue Logic
The EPM5192LC-25 fits legacy bus-interface glue logic applications because its 192 macrocells provide enough capacity to consolidate multiple 22V10-style PAL/GAL decoders into a single device, while the 25 ns tPD meets ISA-bus and VMEbus timing budgets. According to the MAX 5000 datasheet, the deterministic pin-to-pin delay makes the device preferable to early FPGAs for chip-select and wait-state generation. Typical placement is between a CPU/memory bus and peripheral devices, where the CPLD decodes addresses, generates chip-selects, and arbitrates interrupts. Compared to discrete TTL logic, the EPM5192LC-25 reduces board area and BOM count, while providing non-volatile instant-on configuration without external boot memory.

Address Decoding and Chip-Select Generation
Address decoding and chip-select generation is a flagship CPLD use case where the EPM5192LC-25 excels because the wide AND/OR macrocell array is purpose-built for sum-of-products decoding. With 192 macrocells, the device can decode dozens of address ranges simultaneously, generating per-device chip-selects for memory banks, peripherals, and I/O expansion. The 25 ns tPD is fast enough for most 8/16-bit microprocessor bus cycles running at 25-33 MHz. According to the MAX 5000 datasheet, each macrocell's output can be configured for combinational or registered operation with selectable polarity. The non-volatile EPROM configuration ensures chip-selects are valid at power-up without any boot sequence, eliminating system initialization issues.

Industrial State-Machine Controllers
The EPM5192LC-25 is well suited to industrial state-machine controllers because the MAX 5000 macrocell flip-flops provide dedicated registered outputs with predictable timing, ideal for implementing Moore and Mealy state machines. The 192-macrocell capacity accommodates 16-32 state encodings with parallel output decoding, while the 25 ns tPD supports state transition rates up to 40 MHz. Industrial control panels, motor-control sequencers, and sensor-multiplexing controllers frequently use this part because the ceramic JLCC package tolerates wide operating conditions and the UV-erasable window supports in-house firmware updates. Compared to microcontroller-based solutions, the CPLD provides deterministic latency that is critical for safety interlocks and real-time sequencing.

Peripheral I/O Expansion and Port Multiplexing
Peripheral I/O expansion benefits from the EPM5192LC-25's high I/O count and flexible pin assignment - the device can map any internal signal to any I/O pin, eliminating the PCB-routing constraints of fixed-pin PAL devices. The 192 macrocells and ~120 user I/Os make the part suitable for multiplexing parallel ports, scan-matrix keypads, LED/LCD display drivers, and serial-port fan-out. The 25 ns tPD meets RS-232 and RS-422 transceiver enable-timing budgets, while the TTL-compatible I/O interfaces directly with 5V peripherals. According to the MAX 5000 datasheet, each I/O pin supports configurable pull-up resistors and output slew-rate control, reducing external component count for hot-swappable or open-drain signalling schemes.

Obsolete Bipolar PAL Replacement
The EPM5192LC-25 is widely used as a modern replacement for obsolete bipolar PAL devices (e.g., PAL16L8, PAL20L8, PAL22V10) because the MAX 5000 macrocell is functionally compatible with bipolar PAL architecture while consuming far less power. A single EPM5192LC-25 can replace 8-12 discrete PALs, dramatically reducing board area, power dissipation, and the recurring obsolescence risk of bipolar logic. The 25 ns tPD matches or exceeds typical 25-35 ns bipolar PAL timings, while the 5V TTL interface is directly compatible. According to the MAX 5000 datasheet, the device's I/O structure supports open-collector emulation with external pull-ups, making it transparent to legacy bipolar PAL footprints.

Military and Aerospace Maintenance Programs
The EPM5192LC-25 in its ceramic LC package continues to serve military and aerospace maintenance programs where the original MAX 5000 silicon was qualified under MIL-STD-883 or similar standards. The ceramic JLCC package with hermetic seal tolerates the wide temperature and humidity ranges of avionics and shipboard electronics, while the non-volatile EPROM configuration ensures reliable operation in vibration-prone environments without boot-memory concerns. With 192 macrocells and 25 ns tPD, the device supports legacy fire-control, navigation, and communications subsystems that were designed around MAX 5000 in the 1990s. Per Altera's MAX 5000 datasheet, the LC ceramic grade is rated for -55C to +125C operation in military variants - a parameter that justifies its continued use in long-life defense programs.

Catatan Desain
The EPM5192LC-25 is obsolete and no longer in active production. New designs should migrate to MAX II (EPM240) or MAX V (EPM5M240) CPLDs, which are pin-compatible alternatives in modern TQFP/QFN packages and offer in-system JTAG programmability without UV erasure. Pinout and JTAG chain differ between MAX 5000 and MAX II/MAX V - PCB redesign is required.
Place decoupling capacitors (0.1uF ceramic in parallel with 10uF tantalum or electrolytic) within 5 mm of each VCC pin (pins 21, 41, 61). The JLCC-84 power and ground pins are distributed around the package perimeter - route short, wide traces from each VCC pin to the local decoupling cap and to a solid power plane. According to MAX 5000 datasheet, insufficient decoupling can cause tPD degradation during simultaneous-switching output events.
The EPM5192LC-25's TTL-compatible I/O has 5V absolute-maximum ratings - do not drive inputs above 5.5V or below -0.5V. For mixed-voltage designs (3.3V peripherals), add series resistors or level-translator buffers. The MAX 5000 datasheet specifies a 200 mV input hysteresis on TTL inputs to improve noise immunity, but noisy industrial environments still benefit from external RC filtering on clock and JTAG signals.
Informasi Konformitas
