Typical Applications
EPM9480RC208-20 is suitable for 6 applications: PCI/ISA Bus Interface Logic, Microprocessor Address Decoding, Industrial Control State Machines, Telecommunications Backplane Glue Logic, Legacy VME and Multibus Systems, Power-Sequencing and Supervisor Logic.
PCI/ISA Bus Interface Logic
The EPM9480RC208-20 is well suited to legacy PCI and ISA bus-interface glue logic where 560 macro cells provide ample capacity for address decoding, wait-state generation, and bus-cycle translation. The 20 ns pin-to-pin delay comfortably meets PCI 33 MHz timing budgets (30 ns period), and the 5V I/O matches PCI/ISA signalling levels without external transceivers. Designers typically implement target/slave decoders, interrupt controllers, and DMA state machines in a single device, replacing multiple 22V10 or 16V8 PALs with one CPLD.
Recommended
Microprocessor Address Decoding
Address decoding for microprocessor memory maps is a canonical MAX 9000 application. The EPM9480RC208-20's 560 macro cells comfortably handle chip-select generation for complex memory and peripheral maps with multiple wait-state outputs. Its 20 ns propagation delay introduces minimal insertion latency, and the non-volatile EEPROM configuration means the device is fully operational within nanoseconds of power-up - critical for boot ROM chip-select generation where FPGAs would not yet be configured.
Recommended
Industrial Control State Machines
Industrial automation controllers benefit from the EPM9480RC208-20's deterministic timing, 5V tolerance, and instant-on non-volatile configuration. The 560 macro cells accommodate multi-state sequential machines for motor control sequencing, sensor debouncing, and safety-interlock logic. Predictable 20 ns pin-to-pin timing simplifies worst-case latency analysis for safety-critical paths, and the 208-pin RQFP package's generous I/O count supports direct interfacing to multiple 24V-tolerant opto-isolated inputs.
Recommended
Telecommunications Backplane Glue Logic
Legacy telecommunications backplanes rely on CPLDs like the EPM9480RC208-20 for serial-to-parallel conversion, framing logic, and clock-domain crossing between TDM buses. The 5V I/O matches traditional telecom line-interface voltages, and the 560 macro cells handle multi-channel protocol adaptation in a single device. Deterministic 20 ns timing simplifies compliance testing against telecom jitter specifications.
Recommended
Legacy VME and Multibus Systems
The EPM9480RC208-20 is well matched to legacy VMEbus and Multibus interface designs where bus arbitration, interrupt handling, and address mapping require substantial combinational logic. The 208-pin RQFP package provides the high I/O count required for full 32-bit bus implementations, and the 5V supply matches VMEbus signalling directly. Long-term availability through distributors supports continued production of legacy industrial and military systems.
Recommended
Power-Sequencing and Supervisor Logic
Power-supply sequencing for multi-rail systems is an ideal fit for the EPM9480RC208-20's instant-on non-volatile behaviour. The CPLD can power up fully configured before any supervisory reset is released, eliminating the race condition between FPGA configuration and power-rail ramp. 560 macro cells support sequencing of 8-16 rails with fault-propagation and timing-margin monitoring. The 20 ns delay is negligible compared to power-rail rise times.

Key Differentiators
- Highest-density 20 ns option in MAX 9000 208-pin RQFP family (vs EPM9480RC208-15)
- Larger macro-cell count at same footprint vs EPM9320RC208-20 (vs EPM9320RC208-20)
- Mature, broadly available MAX 9000 silicon (vs EPM9400RC208-20)
Design Notes
The EPM9480RC208-20 operates from a single 5V supply. Place 0.1 uF ceramic decoupling capacitors within 5 mm of every VCC and GND pin pair, and add a 10 uF bulk tantalum or ceramic capacitor near the package. Because the device is CMOS and quiescent current is low, most supply noise comes from I/O switching transients; adequate decoupling prevents VCC droop during simultaneous-output switching events.
Estimated: at maximum toggle rate on 100 I/O pins at 20 MHz with 50 pF loads, dynamic power dissipation is approximately P = C*V^2*f*N = 50e-12 * 25 * 20e6 * 100 ≈ 0.25 W. The 208-pin RQFP has theta_JA of roughly 35 C/W, producing a junction temperature rise of ~9 C above ambient. No heatsink is required for typical operating conditions.
Do not apply voltages above 5.5V to any I/O pin - the MAX 9000 family is not 5V-tolerant on outputs driven by external sources. Use current-limiting series resistors on JTAG TCK/TMS/TDO/TDI lines if the programming cable shares a bus with 3.3V devices. Always configure unused pins as outputs driving low or as inputs with internal pull-ups enabled to minimize supply current.
Compliance Information
EPM9480RC208-20 was originally released in the late 1990s; lead-free reflow variants exist (EPM9480RC208-15N) but RoHS compliance status for the standard -20 variant is not confirmed by the verified web data.
