EPM7192EQC160-20 概述
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell arrays on a single chip, providing deterministic timing, instant-on operation, and high-drive I/O for glue-logic, bus-interface, and state-machine applications. In the broader system hierarchy, the EPM7192EQC160-20 sits between small FPGAs and discrete logic ICs, offering instant-on behavior (no boot PROM required), predictable timing for register-rich designs, and 5 V tolerant I/Os that are increasingly rare in modern logic families.
Key features include 192 macrocells distributed across 4 Logic Array Blocks, 36 I/O pins routed through programmable interconnect, programmable power-saving mode per macrocell, programmable security bit for design protection, and JTAG-based ISP that allows board-level reconfiguration without removing the device. The 20 ns speed grade provides a 50 MHz fCNT internal counter frequency and supports combinatorial and registered logic at typical 5 V system clocks.
Architecturally, the MAX 7000 family uses second-generation MAX architecture with EEPROM process technology, providing non-volatile configuration storage that retains state through power cycles. The Programmable Interconnect Array (PIA) routes signals between LABs and I/O pins with predictable delays that simplify static-timing closure versus SRAM-based FPGAs. Each macrocell contains a programmable AND/OR array plus a configurable flip-flop that can be bypassed for pure combinatorial outputs.
Typical applications include industrial control glue-logic, 5 V system bus interfacing, JTAG-controlled I/O expansion, address decoding for legacy microprocessor boards, and pin-compatible replacement for older MAX 7000 designs where instant-on, non-volatile configuration is required. The wide 5 V tolerance makes it especially attractive for industrial 5 V designs where 3.3 V-only modern CPLDs are unsuitable.
When designing with this part, note that the PQFP-160 package requires fine-pitch PCB layout with controlled-impedance traces; place decoupling capacitors (0.1 uF and 10 uF) as close as possible to each VCC/GND pair, and use a JTAG header that meets IEEE 1149.1 specifications for in-system programming access. Verify the JTAG chain length and TCK pull-up/down values against the JTAG specification for reliable ISP operation.

典型应用
EPM7192EQC160-20 适用于 6 应用s: Industrial 5V Glue Logic, Legacy Microprocessor Bus Interface, JTAG-Controlled I/O Expansion, State Machine and Protocol Bridge, 5V System Address Decoder, Pin-Compatible Legacy Replacement.
Industrial 5V Glue Logic
The EPM7192EQC160-20 is a strong fit for industrial 5 V glue-logic applications because of its 4.75 V to 5.25 V single-supply operation and 5 V tolerant I/Os, which most modern 3.3 V-only CPLDs cannot provide. With 192 macrocells and 124 user I/O pins, it can absorb wide address/data bus decoding, chip-select generation, and bus-arbitration glue logic that previously required multiple discrete PAL/GAL devices. Placed on a 5 V industrial backplane, it replaces 3-5 discrete 22V10/16V8 PLDs, reducing board area and BOM cost while delivering deterministic 20 ns propagation delay for register-rich state machines. The non-volatile EEPROM configuration means the board powers up in a known state with no boot PROM, which is critical for industrial safety systems that must come up correctly after power cycling.
推荐
Legacy Microprocessor Bus Interface
The EPM7192EQC160-20 fits legacy 5 V microprocessor bus-interface designs (e.g., 8086, 68000, VMEbus) that need address decoding, wait-state generation, interrupt prioritization, and bus arbitration in a single non-volatile device. With 192 macrocells it can implement 12-16 chip-select decoders plus bus-control state machines in one chip, replacing a board full of discrete 22V10s and 74LS series logic. The 20 ns pin-to-pin delay comfortably meets 8 MHz and 16 MHz bus timings and still leaves margin for 25 MHz designs. Its PQFP-160 footprint is shared with the entire MAX 7000 family, so designers can swap in higher-speed grades like the EPM7192SQC160-10 if timing headroom becomes a concern without redesigning the PCB.
推荐
JTAG-Controlled I/O Expansion
The EPM7192EQC160-20 enables JTAG-controlled I/O expansion thanks to its built-in IEEE Std. 1149.1 boundary-scan interface and 5.0 V in-system programmability. The boundary-scan chain can be used in production to test board interconnects, while the same JTAG port re-flashes the device when firmware needs to change in the field. With 124 user I/O pins, it can drive 5 V signals across multiple backplanes or test fixtures without external level shifters. Compared to discrete TTL I/O expanders, the EPM7192EQC160-20 offers programmable direction control per pin and user-defined register logic that can be updated without removing the chip from the board.
推荐
State Machine and Protocol Bridge
The EPM7192EQC160-20 is well suited to implementing custom state machines and protocol bridges between 5 V peripherals, such as UART-to-parallel converters, SPI-to-I2C bridges, or proprietary bus arbiters. With 192 macrocells across 4 LABs, it has the headroom to encode 32-64 state elements plus combinatorial decode logic in one device, while the deterministic 20 ns timing lets designers verify worst-case propagation paths without complex static-timing analysis. Its PQFP-160 footprint simplifies layout in dense backplane designs, and the EEPROM-backed configuration means the bridge starts instantly at power-on with no boot latency, which matters for deterministic industrial protocols that cannot tolerate startup delays.
推荐
5V System Address Decoder
The EPM7192EQC160-20 is an excellent fit for 5 V system address decoding in embedded motherboards where multiple peripherals share a common bus. With 192 macrocells, it can decode 16-24 address lines and generate individual chip-selects for memory banks, I/O peripherals, and DMA controllers without external logic. The 5 V I/O tolerance means it can interface directly to 5 V microprocessors, ISA-bus peripherals, and legacy memory chips that 3.3 V-only modern CPLDs cannot drive. The non-volatile EEPROM configuration means the decode map is locked in at power-on, eliminating the boot-time ambiguity of SRAM-based FPGAs that need a configuration PROM.
推荐
Pin-Compatible Legacy Replacement
The EPM7192EQC160-20 is widely used as a pin-compatible legacy replacement for older MAX 7000 designs that are being redesigned or respun due to component obsolescence. Because every MAX 7000 160-pin PQFP variant (EPM7192S, EPM7192E, EPM7192, etc.) shares the same 160-pin footprint and JTAG pinout, the EPM7192EQC160-20 can be substituted onto existing PCBs that previously used faster or slower grades. The 20 ns delay is often sufficient for designs that were originally specified at 25-35 ns, and the EEPROM-based configuration means existing programming files can be re-targeted with no hardware changes.

- Non-volatile EEPROM configuration with instant-on behavior （对比 SRAM-based FPGAs/CPLDs)
- Pin-compatible upgrade path within MAX 7000 family （对比 EPM7192SQC160-10)

设计说明
Place 0.1 uF decoupling capacitors as close as possible to each VCC/GND pin pair of the EPM7192EQC160-20, and add at least one bulk 10 uF-47 uF tantalum or ceramic capacitor near the package. The PQFP-160 has many VCC/GND pins distributed around the perimeter; spreading the decoupling uniformly prevents ground bounce on high-speed JTAG transitions and keeps I/O switching noise below 100 mV on the 5 V rail.
Do not confuse the EPM7192EQC160-20 with the EPM7192SQC160-10 - both share the PQFP-160 footprint, but the S suffix indicates 5 V ISP via JTAG and a faster 10 ns delay. Designers migrating to the S variant must confirm that timing closure is acceptable and that existing JTAG programming files can be re-targeted. Similarly, the 'E' suffix variants (EPM7192E) indicate enhanced ISP features; verify with the manufacturer datasheet before assuming software compatibility.
The PQFP-160 lead pitch is 0.65 mm, which requires controlled-impedance routing for signals above 25 MHz to avoid reflections. Use a 4-layer PCB with continuous ground plane under the device; route JTAG signals (TCK, TMS, TDI, TDO) with 50 ohm impedance and keep them away from switching I/O lines. Series termination resistors (22-33 ohm) on critical high-speed outputs reduce ringing and EMI when driving long traces.
Power dissipation is dominated by I/O switching activity and operating frequency. At 50 MHz toggle rate with all 124 I/Os active, typical ICC is around 200-300 mA from the 5 V supply, giving about 1-1.5 W dissipation. Ensure the PQFP-160 thermal pad (if present) is soldered to a copper pour of at least 1 square inch, or attach a small heatsink if the device operates in a sealed enclosure with limited airflow.
