A CPLD (Complex Programmable Logic Device) is a programmable logic IC that combines the flexibility of an FPGA with the non-volatile, instant-on behavior of a PAL. CPLDs sit in the programmable logic hierarchy as CPLD -> programmable logic device (PLD) -> digital logic IC -> semiconductor. The MAX 9000 family is built on Altera's third-generation Multiple Array MatriX (MAX) architecture, using CMOS EEPROM cells for configuration storage, so the device is live immediately at power-up with no external configuration memory.
Key features of the EPM9560RI240-20 include 560 macrocells, 191 user I/O pins, 20 ns pin-to-pin delay, and 5.0 V in-system programmability (ISP). The EEPROM-based architecture provides non-volatile configuration, eliminating the boot PROM required by SRAM-based FPGAs. The 240-pin RQFP package with exposed pad supports high I/O count in a surface-mount footprint.
The MAX 9000 architecture uses a hierarchical routing scheme with logic array blocks (LABs) feeding a central interconnect array, giving predictable timing independent of routing. This deterministic timing is a key advantage over FPGA architectures for glue-logic, bus-interface, and state-machine designs where worst-case delay must be guaranteed.
Typical applications include legacy industrial control boards, bus bridging and address decoding, telecommunications line-card glue logic, test and measurement instrumentation, and replacement of discrete 74-series logic. The 5.0 V I/O interface is directly compatible with TTL and 5 V CMOS logic, simplifying interfacing to legacy peripherals.
When designing with this device, verify that the 240-pin RQFP land pattern matches the PowerQuad II footprint and provide adequate thermal relief on the exposed pad. Because the part is a mature MAX 9000 device, confirm lifecycle status and availability before committing to new production.

典型應用
EPM9560RI240-20 適用於 6 應用s: Legacy Industrial Control Boards, Bus Bridging and Address Decoding, Telecommunications Line Cards, Test and Measurement Instrumentation, Replacement of Discrete 74-Series Logic, Military and Aerospace Legacy Upgrades.
Legacy Industrial Control Boards
The EPM9560RI240-20 fits legacy industrial control boards because its 5.0 V I/O is directly compatible with TTL and 5 V CMOS logic, and its 191 user I/O pins can absorb the address decoding, chip-select generation, and glue logic that would otherwise require dozens of 74-series packages. The industrial temperature grade (-40C to +85C) matches the environmental requirements of factory-floor equipment. Because the MAX 9000 architecture uses non-volatile EEPROM cells, the device is live immediately at power-up with no configuration PROM, which is critical for controllers that must not have a boot delay. The 20 ns pin-to-pin delay is adequate for the low-speed bus cycles typical of legacy industrial backplanes, and the deterministic timing of the MAX 9000 interconnect array guarantees worst-case delay without post-route timing analysis.
推薦
Bus Bridging and Address Decoding
The EPM9560RI240-20 is well suited to bus bridging and address decoding because its 560 macrocells can implement wide address comparators, wait-state generators, and protocol translators between dissimilar buses. The 191 user I/O pins allow direct connection to a 32-bit address bus plus control and data strobes without external multiplexing. The 20 ns propagation delay supports bus cycles in the tens-of-nanoseconds range, and the MAX 9000 central interconnect array provides predictable, routing-independent timing so worst-case address decode delay can be guaranteed at design time. The 5.0 V interface matches legacy PCI, ISA, and VME signaling levels, and the non-volatile EEPROM configuration means the bridge logic is active from the first clock edge after power-up, avoiding the configuration latency of SRAM-based FPGAs.
推薦
Telecommunications Line Cards
The EPM9560RI240-20 suits telecommunications line-card glue logic because it consolidates clock multiplexing, framer interfacing, and status register logic into a single 240-pin device. The 560 macrocells provide enough capacity for state machines that manage T1/E1 or SONET overhead channels, while the 191 user I/O pins connect to backplane control signals and local status LEDs. The 5.0 V I/O is compatible with the legacy telecom logic levels used on many installed line cards, and the industrial temperature grade supports the thermal environment of central-office equipment. The non-volatile EEPROM configuration ensures the line card is operational immediately after power restoration, which is important for high-availability telecom systems where boot latency is unacceptable.
推薦
Test and Measurement Instrumentation
The EPM9560RI240-20 is used in test and measurement instrumentation for trigger logic, pattern generation, and instrument bus control. Its 20 ns pin-to-pin delay supports trigger-to-output latencies in the tens of nanoseconds, and the deterministic MAX 9000 timing model lets designers bound worst-case trigger jitter without exhaustive simulation. The 560 macrocells can implement counters, comparators, and sequencers that would otherwise require multiple discrete ICs, reducing board area and component count. The 5.0 V I/O interfaces directly with legacy instrument backplanes and GPIB-style control logic, and the non-volatile configuration means the instrument is ready to measure immediately at power-on, with no FPGA configuration step that could delay the first measurement.
推薦
Replacement of Discrete 74-Series Logic
The EPM9560RI240-20 replaces large banks of discrete 74-series logic by integrating counters, shift registers, multiplexers, and decoders into one 240-pin CPLD. A single EPM9560RI240-20 with 560 macrocells can absorb the function of dozens of 74HC/74LS packages, cutting board area, power, and assembly cost while improving reliability by reducing solder joints. The 5.0 V I/O is directly compatible with 74-series logic levels, so existing designs can be migrated without level shifters. The 20 ns propagation delay is comparable to or faster than many 74-series glue paths, and the non-volatile EEPROM configuration removes the need for configuration memory, making the CPLD a true power-on-ready replacement for hard-wired logic.
推薦
Military and Aerospace Legacy Upgrades
The EPM9560RI240-20 is used in military and aerospace legacy upgrades where 5.0 V logic and non-volatile configuration are required. The industrial temperature grade supports many avionics and ground-equipment environments, and the EEPROM-based MAX 9000 architecture provides instant-on operation that is valuable in systems where a configuration PROM failure would be catastrophic. The 560 macrocells and 191 user I/O pins allow consolidation of legacy glue logic onto a single device, reducing the number of components subject to obsolescence. The deterministic timing of the MAX 9000 interconnect array simplifies worst-case timing analysis for safety-related functions, and the 240-pin RQFP package is compatible with existing board layouts designed around the EPM9560 family.

主要差異化特點
- Industrial temperature grade (對比EPM9560RC240-20)

- High I/O count in a single package (對比EPM9560RI240-10)
設計說明
The 240-pin RQFP (PowerQuad II) package requires a fine-pitch land pattern with a thermal pad. Follow the Altera MAX 9000 device pin-out and land-pattern guidance for the 240-pin RQFP, and connect the exposed pad to a ground plane with multiple thermal vias. Because the package is fine-pitch, use solder-mask-defined pads and verify paste stencil aperture against the manufacturer land pattern before production.
The EPM9560RI240-20 is a 5.0 V device, so decouple each VCC pin with a 0.1 uF ceramic capacitor placed as close to the pin as possible, plus a bulk 10 uF capacitor per power rail. Estimated: with 191 user I/O pins switching, transient current can be significant; keep the power-plane impedance low and avoid routing I/O traces under the device where they could couple into the supply. Verify the actual supply current from the manufacturer datasheet for your design's toggle rate.
Because the EPM9560RI240-20 is a mature MAX 9000 device, confirm lifecycle status and availability before committing to new production. Do not assume the -20 speed grade is interchangeable with faster grades without re-checking timing: the -15 and -10 parts are faster, but if your design was characterized at 20 ns, verify that the faster grade does not introduce hold-time or race issues in asynchronous interfaces.
