EPM9560RC240-20C 概述
A CPLD (Complex Programmable Logic Device) is a programmable logic IC that combines the flexibility of a field-programmable gate array with the non-volatile, instant-on characteristics of a PAL. CPLDs sit in the programmable logic hierarchy between simple PLDs and FPGAs: CPLD -> programmable logic device -> digital logic IC -> semiconductor. The MAX 9000 family uses EEPROM configuration cells, so the EPM9560RC240-20C retains its configuration without an external boot PROM and is live within microseconds of power-up.
Key features include 560 macrocells organized into 35 logic array blocks (LABs), 12,000 usable gates, 216 maximum user I/O pins, a 20 ns pin-to-pin propagation delay (tPD1), and a 144 MHz internal counter frequency (fCNT). The device supports 5.0 V in-system programmability (ISP) and is specified for 0 C to 70 C commercial operation.
The MAX 9000 architecture routes signals through a programmable interconnect array that feeds 35 LABs, each containing 16 macrocells with individual product-term allocation. This architecture delivers deterministic, predictable timing - a critical advantage over SRAM-based FPGAs for glue-logic, bus-interface, and state-machine functions where worst-case delay must be guaranteed.
Typical applications include PCI and ISA bus bridging, memory controller glue logic, industrial control state machines, telecommunications line-card logic, and legacy system replacement where 5 V logic levels and instant-on operation are required.
When designing with the EPM9560RC240-20C, note that it is a 5.0 V-only device and is not 3.3 V tolerant on all pins; level shifting is required when interfacing to modern 3.3 V or 1.8 V logic. The 240-pin RQFP package requires careful thermal and signal-integrity planning at 144 MHz.
This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a single reference for replacement and redesign decisions.

典型应用
EPM9560RC240-20C 适用于 6 应用s: PCI/ISA Bus Bridge Logic, Industrial Control State Machines, Telecommunications Line-Card Logic, Legacy System Replacement and Obsolescence Mitigation, Test and Measurement Instrument Control, Military and Aerospace Legacy Upgrades.
PCI/ISA Bus Bridge Logic
The EPM9560RC240-20C fits PCI and ISA bus-bridge glue logic because its 216 user I/O pins and 560 macrocells can absorb address decoding, wait-state generation, and bus arbitration in a single non-volatile device. With a 20 ns pin-to-pin delay and 144 MHz internal counter frequency, it meets the timing budget of 33 MHz PCI and 8 MHz ISA buses with margin. Because the MAX 9000 architecture is EEPROM-based, the bridge logic is live microseconds after power-up, eliminating the boot-PROM delay of SRAM FPGAs. The trade-off is that the 5.0 V supply and non-3.3 V-tolerant I/O require level shifting when bridging to modern low-voltage buses.
推荐
Industrial Control State Machines
The EPM9560RC240-20C is well suited to industrial control state machines because its 560 macrocells and 35 LABs implement large deterministic FSMs with guaranteed 20 ns worst-case delay, unlike SRAM FPGAs whose routing delay varies with placement. The 5.0 V CMOS I/O interfaces directly with legacy 5 V sensors, relays, and PLC backplanes, and the EEPROM configuration survives power cycling without a configuration PROM. At 144 MHz fCNT the device can oversample slow industrial signals for debouncing and edge detection. Designers should note the 0 C to 70 C commercial rating and select an industrial-temperature MAX 9000 variant if the enclosure exceeds 70 C.
推荐
Telecommunications Line-Card Logic
The EPM9560RC240-20C serves telecommunications line-card glue logic where 216 I/O pins map multiple T1/E1 framers, HDLC controllers, and backplane interfaces into one CPLD. Its 560 macrocells implement channel-associated signaling state machines and timeslot interchange control, while the 20 ns tPD1 keeps setup/hold margins comfortable at 8 MHz backplane rates. The non-volatile EEPROM configuration means line cards resume traffic immediately after a power hit, an important availability requirement in central-office equipment. The 5.0 V core simplifies interfacing to legacy telecom components, but modern 3.3 V line-card controllers need level translation on shared buses.
推荐
Legacy System Replacement and Obsolescence Mitigation
The EPM9560RC240-20C is frequently used to replace obsolete PALs, GALs, and discrete 74-series glue logic in legacy systems because one 240-pin RQFP device absorbs dozens of small logic packages while preserving 5.0 V TTL-compatible levels. Its 12,000 usable gates and 560 macrocells consolidate address decoders, wait-state generators, and DMA controllers into a single reprogrammable part, reducing board area and component count. Because the MAX 9000 family is itself now obsolete, designers should stock drop-in same-family parts such as the EPM9560RC240-20 and EPM9560RC240-15, or plan a migration to a modern CPLD with a level-shifting interface.
推荐
Test and Measurement Instrument Control
The EPM9560RC240-20C is used in test and measurement instruments for trigger logic, counter/timer control, and front-panel interface sequencing. Its 144 MHz internal counter frequency supports precision event counting, while the 20 ns deterministic delay ensures repeatable trigger latency - a requirement in automated test equipment where jitter degrades measurement uncertainty. The 216 user I/O pins drive front-panel LEDs, relays, and attenuator control lines directly from 5.0 V CMOS outputs. The EEPROM configuration guarantees the instrument boots into a known logic state without a configuration PROM, simplifying field service and calibration.
推荐
Military and Aerospace Legacy Upgrades
The EPM9560RC240-20C appears in military and aerospace legacy upgrades where 5.0 V logic and instant-on EEPROM configuration are mandatory. Its 560 macrocells implement redundant voting logic, bus monitors, and interface protocol converters, and the deterministic 20 ns timing simplifies worst-case timing analysis required by safety reviews. The non-volatile configuration eliminates single-event-upset risk in the configuration memory that affects SRAM FPGAs, an advantage in radiation-adjacent environments. Note that the commercial 0 C to 70 C grade is not suitable for extended-temperature military use; industrial or military-temperature MAX 9000 variants should be selected for those programs.

设计说明
The EPM9560RC240-20C requires a well-regulated 5.0 V supply with adequate decoupling on every VCC pin. Place a 0.1 uF ceramic capacitor within 5 mm of each VCC/GND pin pair and add a 10 uF bulk capacitor per power plane. Estimated: at 144 MHz operation the device can draw several hundred milliamps, so size the regulator and copper pour for the worst-case switching current rather than the quiescent value. Verify the actual ICC from the MAX 9000 datasheet for your design's toggle rate.
At 144 MHz internal counter frequency and 20 ns pin-to-pin delay, the EPM9560RC240-20C's 240-pin RQFP package demands controlled-impedance routing for high-speed I/O. Keep clock traces short, reference them to a solid ground plane, and terminate long nets with series resistors near the driver. Avoid routing high-speed signals across plane splits, which causes return-path discontinuities and radiated emissions. The 5.0 V CMOS output edges are fast enough to require attention to crosstalk between adjacent I/O pins.
The EPM9560RC240-20C is a 5.0 V-only device and is not fully 3.3 V tolerant on all pins. Connecting 3.3 V logic directly to its inputs can forward-bias protection structures and cause excessive current; use level shifters or series resistors and verify input voltage limits in the MAX 9000 datasheet. Also confirm the 0 C to 70 C commercial temperature grade is adequate for the enclosure, and remember the part is obsolete - qualify a drop-in same-family replacement before production.
