EPM9560RC240-20N 概要
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 behavior of a PAL/PLD. CPLDs sit in the programmable logic hierarchy between simple PLDs and FPGAs: PLD -> CPLD -> FPGA -> programmable logic device. The MAX 9000 family is built on Altera's third-generation Multiple Array MatriX (MAX) architecture, using CMOS EEPROM configuration cells that retain their programmed state without external configuration memory.
Key features of the EPM9560RC240-20N include 560 macrocells organized into 35 logic array blocks (LABs), 12,000 usable gates, 216 user I/O pins, and 5.0 V in-system programmability (ISP). The EEPROM-based configuration provides instant-on operation, eliminating the boot delay and configuration PROM required by SRAM-based FPGAs. The 20 ns speed grade (-20) delivers 144 MHz counter performance and 3.0 ns flip-flop setup time (tSU).
The MAX 9000 architecture uses a continuous interconnect array that provides deterministic, uniform pin-to-pin timing independent of routing, which simplifies static timing analysis compared with segmented FPGA routing. Each macrocell contains a programmable flip-flop with individual clock, clear, and preset control, allowing mixed sequential and combinatorial logic in a single device.
Typical applications include glue logic consolidation, bus bridging and protocol conversion, address decoding, state machines, and legacy system replacement where 5.0 V logic levels and instant-on operation are required. The 240-pin RQFP package provides 216 I/O for wide bus interfaces.
When designing with this device, note that the -20 speed grade is the slowest MAX 9000 grade; timing-critical paths should be verified against the 20 ns tPD1 and 3.0 ns tSU limits. The 5.0 V core also requires level shifting when interfacing with modern 3.3 V or 1.8 V logic.
This page synthesizes distributor pricing, drop-in speed-grade alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a single reference for sourcing and migration decisions.

主な用途
EPM9560RC240-20N の用途: 6 件s: Legacy Bus Bridging and Protocol Conversion, Address Decoding and Chip-Select Logic, State Machine and Sequencer Implementation, Glue Logic Consolidation, Industrial Control and Automation, Test and Measurement Instrumentation.
Legacy Bus Bridging and Protocol Conversion
The EPM9560RC240-20N fits legacy bus bridging because its 216 user I/O pins and 560 macrocells can implement wide address/data bus translation between 5.0 V ISA, VME, or custom backplane interfaces and peripheral devices. With a 20 ns pin-to-pin delay and 144 MHz counter frequency, it handles bus-cycle timing with margin at 5.0 V logic levels. The device is placed between two bus domains, decoding addresses in combinatorial macrocells and latching data in registered macrocells. Unlike a modern 3.3 V CPLD, it natively drives 5.0 V TTL/CMOS buses without level shifters, but it consumes more static power and is obsolete, so it suits maintenance of existing boards rather than new designs.
おすすめ
Address Decoding and Chip-Select Logic
The EPM9560RC240-20N is well suited to address decoding because its 35 logic array blocks and 560 macrocells can generate dozens of chip-select and enable terms from a wide address bus. The 20 ns tPD1 and 3.0 ns flip-flop setup time allow registered decode outputs that meet typical 5.0 V microprocessor bus timing. In a typical implementation, address lines feed combinatorial macrocells that AND/OR decode terms, while registered macrocells synchronize chip-select assertion to the bus clock. The continuous interconnect array gives deterministic, routing-independent delay, simplifying worst-case timing analysis. The trade-off versus a modern CPLD is higher 5.0 V power and an obsolete supply chain, so the part is best reserved for legacy system repair.
おすすめ
State Machine and Sequencer Implementation
The EPM9560RC240-20N implements finite state machines and power-up sequencers using its 560 macrocells, each with a programmable flip-flop featuring individual clock, clear, and preset control. The 144 MHz internal counter frequency supports fast state transitions, while the 3.0 ns flip-flop setup time allows reliable clocking at system speeds. Designers map state registers into macrocells and next-state logic into the logic array, using the continuous interconnect for uniform timing. A key advantage over discrete 74-series logic is single-device integration and in-system reprogrammability via the EEPROM configuration. The limitation is the 5.0 V core and obsolete status, so new sequencer designs should use an active CPLD family instead.
おすすめ
Glue Logic Consolidation
The EPM9560RC240-20N consolidates dozens of discrete 74-series glue-logic devices into one 240-pin RQFP CPLD, reducing board area and part count. Its 12,000 usable gates and 560 macrocells absorb counters, shift registers, multiplexers, and random logic, while 216 user I/O pins connect to surrounding circuitry. The EEPROM configuration is instant-on, so no configuration PROM or boot delay is needed, unlike SRAM-based FPGAs. In practice, engineers replace a cluster of 74HC/74LS parts with a single EPM9560 and reprogram it in-system for design revisions. The trade-off is a higher unit cost and obsolete lifecycle versus discrete logic, so the approach suits legacy boards where space and rework reduction matter most.
おすすめ
Industrial Control and Automation
The EPM9560RC240-20N suits industrial control because its 5.0 V logic levels interface directly with legacy PLC backplanes, relay drivers, and opto-isolated I/O, and its 216 user I/O pins handle wide parallel control buses. The 560 macrocells implement ladder-logic equivalents, timers, and interlocks, while the 20 ns tPD1 ensures deterministic response to sensor inputs. The device is typically placed on a control card between the host processor and field I/O, decoding commands and latching outputs. The continuous interconnect array provides predictable timing for safety-relevant interlocks. However, the commercial 0 C to +70 C rating limits use to controlled environments, and the obsolete status makes it a maintenance-only choice for industrial retrofits.
おすすめ
Test and Measurement Instrumentation
The EPM9560RC240-20N is used in test and measurement equipment for pattern generation, trigger logic, and instrument bus interfacing. Its 144 MHz counter frequency supports fast event counting, and the 560 macrocells implement trigger state machines and timestamp logic. The 216 user I/O pins connect to front-end comparators, DACs, and host interfaces, while the 5.0 V levels match legacy instrument backplanes. In a typical design, the CPLD generates stimulus patterns and captures response data under host control, using registered macrocells for glitch-free outputs. The deterministic interconnect delay aids repeatable measurement timing. The main drawbacks are the obsolete supply chain and higher power versus modern CPLDs, so it is best for servicing existing instruments rather than new product development.

設計ノート
The EPM9560RC240-20N requires a regulated 5.0 V supply for both core and I/O. Decouple every VCC pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, plus a bulk 10 uF capacitor per device. Estimated: at a typical 5.0 V CPLD operating current of a few hundred milliamps, a 0.5 V supply droop would exceed the device tolerance, so keep the 5.0 V rail within +/-5% and verify the regulator can supply the transient current during EEPROM programming.
Route the 240-pin RQFP on a board with at least four layers: a dedicated ground plane directly under the device and a power plane for the 5.0 V rail. Keep high-speed clock traces short and reference them to the ground plane to control impedance. Because the MAX 9000 uses a continuous interconnect array with deterministic delay, timing is dominated by I/O trace length rather than internal routing, so match trace lengths on parallel buses to within a few millimeters.
Do not assume the -20N is interchangeable with non-EPM9560 MAX 9000 devices: the EPM9320, EPM9400, and EPM9480 have fewer macrocells and different pinouts despite sharing the family. Also confirm the N suffix for lead-free assembly; the leaded EPM9560RC240-20 requires a different reflow profile. Finally, because the family is obsolete, program and verify a golden sample before committing production stock.
コンプライアンス情報
The N suffix indicates lead-free (RoHS-compatible) terminations, but no explicit RoHS/REACH declaration was present in the verified web data. AEC-Q100 is not applicable (commercial-grade CPLD).
