EPM9560RC/ARC240 개요
A CPLD (Complex Programmable Logic Device) is a non-volatile, reprogrammable digital logic device that combines multiple PAL/PLA-like macrocell arrays on a single chip, connected through a programmable interconnect matrix. CPLDs sit in the programmable logic hierarchy between small SPLDs (a few hundred gates) and FPGAs (which offer higher density but are volatile and require an external boot PROM). Because MAX 9000 devices are EEPROM-based, they retain their configuration without an external memory and offer instant-on behavior at power-up, making them attractive for glue logic, bus interfacing, state-machine control, and address decoding in microprocessor systems.
Key features of the EPM9560RC/ARC240 include 16 dedicated input pins, 4 high-speed global clock networks with programmable clock/clock-enable control, a programmable security bit for design protection, and a JTAG boundary-scan test interface compliant with IEEE Std 1149.1. The device is offered in commercial (0 C to +70 C) and industrial (-40 C to +85 C) speed grades, with propagation delays as low as 10 ns and pin-to-pin logic delays around 16 ns depending on speed grade.
The MAX architecture combines the fine-grained flexibility of EPLDs with the high density of FPGAs. Each Logic Array Block (LAB) contains 16 macrocells, and each macrocell includes a programmable AND/OR/flip-flop array with selectable registered/combinatorial/feedback paths. The predictable timing model of MAX 9000 - fixed-pin, deterministic propagation delays - is the defining engineering advantage versus SRAM-based FPGAs in timing-critical control applications.
Typical applications include high-performance bus decoding for 32-bit/64-bit microprocessors, peripheral glue logic, state-machine control, address demultiplexing, and interface bridging between asynchronous buses. The wide 5 V tolerance and high I/O count also make the part suitable for legacy industrial backplane designs. When designing with this device, allocate one JTAG chain for ISP and place decoupling capacitors within 100 mils of every VCC/GND pair to ensure clean power delivery to the internal EEPROM array during in-system programming.

일반적인 애플리케이션
EPM9560RC/ARC240 적합 용도: 6 애플리케이션s: Microprocessor Bus Decode and Address Mapping, Legacy Industrial Glue Logic Replacement, Peripheral Interface Bridging, State-Machine Control and Sequencing, Address Demultiplexing for Memory Banks, Test Equipment and Instrumentation Front-End.
Microprocessor Bus Decode and Address Mapping
The EPM9560RC/ARC240 excels at 32-bit and 64-bit microprocessor bus decode with its 560 macrocells and 191 user I/Os, allowing the entire chip-select and address-decoding logic for a CPU/memory/peripheral system to be consolidated in a single non-volatile device. With 10 ns tPD on the -10 speed grade, address decoding completes within one clock cycle of systems running up to ~80 MHz. Unlike SRAM FPGAs, the MAX 9000 EEPROM-based architecture means the device boots instantly with no external PROM, simplifying board design. Place the CPLD between the CPU address bus and each peripheral chip-select pin, with the JTAG chain reserved for in-field firmware updates.
추천
Legacy Industrial Glue Logic Replacement
The EPM9560RC/ARC240 is widely deployed as glue logic on legacy industrial backplanes and factory automation controllers, where 5 V-tolerant I/O and high pin count eliminate the need for multiple 74-series TTL parts. The MAX 9000 architecture's deterministic tPD timing model is critical for handshake-based protocols where race conditions would be catastrophic. Up to 191 user I/Os handle dozens of mixed signals in one device, and 12,000 usable gates replace entire boards of discrete logic. The 5 V supply and TTL-compatible thresholds remain compatible with older industrial subsystems that have not migrated to 3.3 V.
추천
Peripheral Interface Bridging
When bridging between mismatched peripheral buses (ISA, VME, PC/104, SCSI, or proprietary parallel protocols), the EPM9560RC/ARC240 provides the protocol-conversion glue logic with non-volatile single-chip simplicity. With 16 dedicated input pins, 4 global clock networks, and 560 macrocells, complex state machines for handshaking, FIFO control, and byte-swapping are absorbed into one CPLD. The deterministic pin-to-pin delay of 16 ns typical simplifies protocol timing closure. JTAG-based in-system programmability allows field firmware updates without removing the board from the chassis.
추천
State-Machine Control and Sequencing
Complex state machines for motor control sequencing, power-supply start-up/shut-down coordination, and fault-handling logic fit naturally in the EPM9560RC/ARC240's macrocell array. Each macrocell includes a programmable flip-flop with selectable registered/combinatorial paths, making the device efficient for Mealy/Moore state-machine implementation. The 144.9 MHz maximum internal frequency supports high-speed sequencer loops. With 4 global clock networks, multiple asynchronous state machines can be synchronized without external clock-distribution buffers.
추천
Address Demultiplexing for Memory Banks
The EPM9560RC/ARC240 handles address demultiplexing and chip-select generation across multiple DRAM/SRAM banks in embedded memory subsystems. With 191 user I/Os, dozens of chip-select, output-enable, and write-enable signals are produced from a single address bus, eliminating discrete decoder chips. The 10 ns tPD on the -10 grade ensures row-address to chip-select timing is satisfied for fast SRAMs. The deterministic timing eliminates hold-time violations common with SRAM FPGA implementations.
추천
Test Equipment and Instrumentation Front-End
Test and measurement instruments use the EPM9560RC/ARC240 for front-panel logic, calibration sequencing, and signal-routing control. The deterministic timing model is essential where test-accuracy windows must be guaranteed regardless of routing. With 560 macrocells, complex self-test routines and calibration state machines fit in one device. The EEPROM-based configuration survives power cycles without reloading, eliminating calibration drift on bench-top equipment. JTAG boundary scan supports in-circuit testability during manufacturing.

설계 노트
Place 0.1 uF ceramic decoupling capacitors within 100 mils of every VCC/GND pair on the EPM9560RC/ARC240. The MAX 9000 EEPROM array draws transient current peaks during in-system programming (ISP), and inadequate decoupling causes programming failures and JTAG chain errors. Use a bulk 10 uF tantalum or ceramic capacitor near the device's primary VCC pin to handle ISP programming surges. With multiple VCC pins distributed around the 240-pin RQFP package, ensure each one has dedicated local decoupling.
The 240-pin RQFP package has 0.500 mm terminal pitch, requiring careful PCB layout to avoid solder bridging during assembly. Use a solder paste stencil with apertures 80% of the pad size, and reflow with a profile matching the package's moisture sensitivity level (MSL). For prototype builds, hand-soldering the fine-pitch RQFP is impractical; use a hot-air rework station or reflow oven. Reserve PCB space for a JTAG header (TDI/TDO/TMS/TCK) for in-system programming access.
The 240-pin RQFP package has limited heat dissipation, and the EPM9560RC/ARC240 can dissipate up to 1.5 W worst case with all 191 I/Os switching at high frequency. Estimated: at 5.0 V with 50% I/O toggling at 100 MHz, internal power is approximately 0.8 W. Above 70 C ambient, derate by 10 mW per degree C, or add a small heat-spreader copper pour beneath the package. For industrial temperature grades (-40 C to +85 C), thermal stress on solder joints is higher; conformal coating is recommended.
The MAX 9000 macrocell output drive is rated for standard TTL loads; for high-speed signals exceeding 50 MHz, use series damping resistors (22-33 ohm) near the CPLD output to reduce transmission-line reflections. Keep clock traces short and use a ground reference plane beneath all clock nets. The 4 global clock networks have lower skew than routed clocks - assign critical clocks to dedicated GCLK pins rather than general I/O.
Do not assume the EPM9560RC/ARC240 is RoHS-compliant without checking the specific suffix ('N' suffix indicates lead-free). Mixing leaded and lead-free parts on the same board violates RoHS assembly directives. Also, the MAX 9000's 5.0 V supply is not directly compatible with 3.3 V logic - level shifters are required for modern low-voltage interfaces. JTAG chain integrity must be verified by checking TCK/TMS pull-up resistors per IEEE 1149.1 specifications.
규정 준수 정보
RoHS/lead-free status depends on suffix (-10 vs -10N). Per Altera's MAX 9000 documentation, lead-free variants carry the 'N' suffix. No AEC-Q100 automotive qualification exists for this part - it is a legacy industrial/commercial CPLD.
