A Programmable Logic Device (PLD) is a digital integrated circuit whose internal logic and interconnections are user-defined after manufacturing, replacing multiple discrete SSI/MSI gates with a single configurable part. Within the broader semiconductor hierarchy, the EPM5192 sits below microcontrollers and FPGAs but above discrete TTL/CMOS gate arrays - it targets glue-logic and state-machine applications where structured logic is needed but full FPGA density is overkill. The "CPLD" hypernym (Complex PLD) reflects this device's multi-block architecture, distinguishing it from simple PAL/GAL devices.
Key features include 192 macrocells of user-configurable logic, 12 LABs with predictable routing through the PIA, a 25 ns pin-to-pin propagation delay (the "-15" speed grade), and OTP (One-Time Programmable) UV-erasable non-volatile configuration memory. The PQFP-100 plastic package provides 64 user I/O pins - a generous ratio that makes the EPM5192 attractive for bus- and peripheral-intensive glue logic. CMOS technology delivers low static power dissipation relative to bipolar predecessors.
The EPM5192 uses a classic MAX-style architecture: each macrocell contains a programmable AND/OR array with an output flip-flop, fed by the global PIA. The "-15" speed grade sets worst-case tPD at 25 ns including interconnect delay, which is sufficient for microprocess bus decoding and standard peripheral state machines running in the 20-40 MHz range. Configuration is stored in EPROM cells (UV-erasable windowless variant in the -15 grade per datasheet classification), making the device suitable for prototype runs and low-volume production.
Typical applications include microprocessor peripheral decoding (8086/68000 address decoding), peripheral bus arbitration, custom state-machine controllers, industrial machine control logic, and legacy system retrofit where the original PAL/GAL solutions were insufficient. The OTP nature also suits production designs that have stabilized and no longer require in-field reprogramming.
When designing with this device, ensure the I/O count does not exceed 64 user I/O pins, and provide proper decoupling (0.1 uF ceramic per VCC pin group). The PQFP-100 package requires careful PCB footprint design; this part is end-of-life on Intel/Altera's active roadmap, so second-source sourcing for new designs is critical.

典型應用
EPM5192AQC100-15 適用於 6 應用s: Microprocessor Address Decoding, Peripheral Bus Arbitration Logic, Custom State-Machine Controllers, Industrial Machine Control Logic, Legacy System Retrofit / Field Repair, Glue Logic for Embedded CPU Boards.
Microprocessor Address Decoding
The EPM5192AQC100-15 fits 8086/68000/68K address-decoding applications through its 192 macrocells and 64 user I/O pins, which together replace dozens of discrete 74LS-series decoder chips. The 25 ns propagation delay is well below typical CPU memory-access cycles (80-200 ns), ensuring the decoder settles before the memory read strobe. With 12 LABs and PIA routing, the device can implement multiple independent decoder channels (chip-select, I/O-mapped select, interrupt-acknowledge) on one chip. Compared to discrete TTL designs, the CPLD reduces board area, power, and component count while improving design flexibility. According to the MAX 5000 datasheet, the device supports 7 dedicated inputs usable as gated clock or asynchronous reset lines, ideal for clean decoder control.
推薦
Peripheral Bus Arbitration Logic
Bus arbitration in multi-master systems (ISA, VME, custom backplane) is well-served by the EPM5192's 192 macrocells, sufficient for 8-16 priority-encoded arbiter trees plus handshake state machines. The 25 ns tPD keeps arbitration propagation below bus-cycle deadlines, and the OTP EPROM configuration is acceptable for production-validated designs. With 64 user I/O the part accommodates request/grant pairs plus address-bus multiplexing in parallel. Compared to a discrete arbiter ASIC, the CPLD allows late-stage protocol changes without mask costs. According to the MAX 5000 datasheet, the predictable PIA routing avoids timing-skew surprises in parallel-arbiter paths.
推薦
Custom State-Machine Controllers
The EPM5192AQC100-15 implements complex Moore/Mealy state machines for industrial control through its 192 flip-flop-equipped macrocells - enough for 20-30 state FSMs with several outputs each. The 12 LAB structure groups related logic close together, reducing PIA delay and yielding clean state-machine timing. With 25 ns tPD the device supports state-transition rates up to 40 MHz, sufficient for serial-protocol engines (UART, SPI) and machine-control sequencers. OTP configuration suits production runs where firmware has stabilized. According to the MAX 5000 datasheet, the dedicated clock input with global distribution minimizes clock skew across all state-machine flip-flops.
推薦
Industrial Machine Control Logic
The EPM5192AQC100-15 fits industrial machine-control applications through 64 user I/O pins that interface to limit sensors, relays, solenoid drivers, and HMI panels, plus 192 macrocells for ladder-logic-to-CPLD translation. The 25 ns delay is fast enough for encoder decoding, PWM generation, and emergency-stop safety chains. CMOS technology with proper decoupling provides good noise immunity for factory-floor environments. OTP EPROM configuration prevents inadvertent reprogramming by line operators. Compared to relay-logic panels, the CPLD shrinks the cabinet, simplifies wiring changes, and improves diagnostics via JTAG boundary-scan.
推薦
Legacy System Retrofit / Field Repair
Field-repair and exact-replica retrofit applications are the primary remaining use-case for the EPM5192AQC100-15, since modern MAX II/MAX V CPLDs cannot reuse the original PQFP-100 PCB footprint without board rework. The obsolete -15 grade preserves exact form, fit, and function for legacy boards in installed industrial, military, and aerospace systems. Its 25 ns timing matches the original design's timing budget. According to the Altera MAX 5000 datasheet, the JTAG interface supports boundary-scan diagnostics useful in field-repair verification.
推薦
Glue Logic for Embedded CPU Boards
The EPM5192AQC100-15 serves as glue logic between microprocessors, memory, and peripherals on embedded SBCs, consolidating address latching, chip-select generation, bus transceivers, and interrupt steering into one 192-macrocell device. Its 64 user I/O pins accommodate typical 8-16 bit bus plus 4-8 chip-selects plus interrupt/control lines without external bus-expanders. The 25 ns propagation delay fits 33-40 MHz embedded CPU bus cycles. OTP EPROM is acceptable for production SBC designs. According to the MAX 5000 datasheet, the 12 LAB architecture enables modular glue-logic IP blocks that can be reused across SBC variants.

主要差異化特點
- Balanced speed-grade position in MAX 5000 family (對比EPM5192AQC100-20)
- PQFP-100 pin count balances I/O and PCB manufacturability (對比EPM5192AGC84-20)
- UV-Erasable EPROM allows prototyping before OTP commitment (對比EPM5192AQC-2)
- Legacy footprint preservation for field repair (對比Modern MAX II/MAX V CPLDs (e.g., EPM240T100C5N))
設計說明
The EPM5192AQC100-15 operates from a single 5V supply (VCC pins 21, 45, 78). Per the MAX 5000 datasheet, ICC active current scales with output switching frequency and output load; estimate 100-300 mA typical for 192-macrocell designs at 25 MHz toggle rate. Place a 0.1 uF ceramic decoupling capacitor adjacent to each VCC pin and a bulk 10-47 uF tantalum or low-ESR electrolytic at the board supply entry. Add a ferrite bead or LC pi-filter on the VCC rail for noisy industrial environments.
The PQFP-100 (R-PQFP-G100) package has 0.65 mm pitch and requires careful PCB layout. Use a 4-layer board with a continuous ground plane beneath the device to provide controlled impedance for signal traces and a thermal path. Estimated: with 192 macrocell utilization at typical 50% toggle rate, expect junction-to-ambient thermal resistance theta_JA of approximately 50-60 C/W (PQFP-100 plastic, still air). Maintain PCB soldermask-defined pads per IPC-7351 PQFP-100 land pattern; use ENIG surface finish for reliable reflow soldering of legacy PQFP packages.
Do not confuse the EPM5192AQC100-15 (PQFP-100, 25 ns, OTP/UV-erasable) with the EPM5192AGC84-20 (also PQFP-100 footprint but different I/O pin mapping for 84-pin variant) - the pin functions differ. The 25 ns propagation delay includes PIA interconnect; if your design needs to operate at the speed-grade edge, leave at least 20% timing margin. JTAG boundary-scan requires TDI/TMS/TCK/TDO pin connections - if unused, tie TMS and TCK high through 10k resistors to prevent floating-state programming errors. Programming requires Altera MAX+PLUS II or Quartus design software with legacy MAX 5000 device support.
Route the global clock input (INPUT1/GCLK1, pin 51) on the top layer with ground-reference shielding on both sides; keep clock trace length matched to other clock-distribution paths if cascading multiple EPM5192 devices. Place output enable pins (OE1, OE2) directly to bus-driver enable lines to minimize skew. Separate analog/mixed-signal traces from the CPLD outputs by at least 3W (3x trace width) to reduce coupling; the EPM5192 is a digital device with fast edge rates (~2-3 ns) that can inject noise into adjacent analog paths.
