Typical Applications
EPM9560RC304-20N is suitable for 6 applications: Industrial Control Backplane Logic, Telecommunications Line Card Glue Logic, PCI and ISA Bus Bridging, Test and Measurement Instrumentation, Legacy System Replacement and Repair, Military and Aerospace Legacy Avionics.
Industrial Control Backplane Logic
The EPM9560RC304-20N fits industrial control backplane logic because its 212 user I/O pins and 560 macrocells can implement wide address/data bus decoding, chip-select generation, and wait-state logic in a single 5.0 V device. Its 20 ns pin-to-pin delay provides deterministic timing that simplifies worst-case analysis in backplane arbitration, and the EEPROM configuration is instant-on, so the controller resumes operation immediately after power-up without a configuration load. The 304-pin RQFP package routes 212 I/O directly to the backplane connector, avoiding external multiplexers. A trade-off is that the 5.0 V core dissipates more power than modern 3.3 V CPLDs, so thermal relief on the RQFP pads is recommended for high-toggle-rate designs.
Recommended
Telecommunications Line Card Glue Logic
The EPM9560RC304-20N is used in telecommunications line cards for glue logic such as TDM bus interfacing, clock domain handoff, and status register aggregation. Its 560 macrocells can absorb the discrete 74-series logic that would otherwise occupy significant board area, and the 100 MHz maximum system frequency supports legacy telecom bus rates. The IEEE Std. 1149.1 JTAG interface enables in-system programming and boundary-scan testing of the assembled line card, reducing production test time. Because the MAX 9000 interconnect is fixed, timing is predictable across all routing, which is valuable for line cards that must pass strict jitter and setup/hold budgets. The main trade-off is limited availability, since the MAX 9000 family is a legacy product line.
Recommended
PCI and ISA Bus Bridging
The EPM9560RC304-20N suits PCI and ISA bus bridging because its 212 I/O pins can directly interface a 32-bit PCI bus and a legacy ISA bus without external transceivers, and its 5.0 V I/O supports ISA signaling natively. The 560 macrocells implement address decoding, byte-enable steering, and wait-state generation, while the 20 ns propagation delay keeps bridge latency within PCI timing budgets. EEPROM configuration means the bridge logic is live immediately at power-up, which is required for boot-time bus enumeration. Designers should note that the 5.0 V core requires careful decoupling and that the 304-pin RQFP package needs a solid ground plane to control simultaneous switching noise on the wide bus.
Recommended
Test and Measurement Instrumentation
The EPM9560RC304-20N is used in test and measurement instrumentation for trigger logic, pattern generation, and instrument bus control. Its deterministic 20 ns pin-to-pin delay allows repeatable trigger timing, which is essential for oscilloscopes and logic analyzers where jitter directly degrades measurement accuracy. The 560 macrocells can implement state machines and counters that would otherwise require multiple discrete ICs, and the 212 I/O pins interface front-panel controls, relays, and data converters. Non-volatile EEPROM configuration ensures the instrument boots into a known state without a configuration PROM. The trade-off is that the 5.0 V supply and RQFP package require more board area and power than a modern low-voltage CPLD.

Legacy System Replacement and Repair
The EPM9560RC304-20N is a primary replacement part for legacy 5.0 V systems that used MAX 9000 CPLDs and can no longer source the original device. Because the MAX 9000 family is EEPROM-based and non-volatile, a replacement device can be reprogrammed with the original JEDEC file and dropped into the existing 304-pin RQFP socket without board changes. The 212 I/O pins and 560 macrocells match the original EPM9560 density, preserving the existing netlist. Engineers should verify the speed grade against the original design's timing budget, since a -20 part may be slower than a -15 original. Availability is the main constraint, as remaining stock is limited to distributor and broker inventory.
Recommended
Military and Aerospace Legacy Avionics
The EPM9560RC304-20N is found in legacy avionics and military systems that were designed around 5.0 V MAX 9000 CPLDs and require long-term form-fit-function replacement. Its EEPROM configuration is immune to the single-event upsets that affect SRAM-based FPGAs, and the fixed interconnect provides deterministic timing that simplifies certification of safety-critical control paths. The 212 I/O pins support wide avionics data buses, and the 304-pin RQFP package matches existing board footprints. Because the part is obsolete, sustainment programs should qualify a pin-compatible speed-grade variant and verify operation over the full military temperature range, which is not specified in the commercial datasheet.

Key Differentiators
- Lead-free RoHS3 package finish (vs EPM9560RC304-20)
- Deterministic 20 ns timing (vs EPM9560RC304-15N)
- Non-volatile EEPROM configuration (vs EPM9560RC304-20C)
Design Notes
The EPM9560RC304-20N requires a stable 5.0 V core supply. Place a 0.1 uF ceramic decoupling capacitor on every VCC pin and a 10 uF bulk capacitor near the device. Because the MAX 9000 architecture draws current in bursts during macrocell switching, keep the supply impedance low across the 1-100 MHz range. Estimated: at 100 MHz with 50% macrocell toggle, dynamic current can reach several hundred milliamps, so verify the regulator can supply the transient without droop.
The 304-pin RQFP package requires a solid ground plane under the device to control simultaneous switching noise on the 212 I/O pins. Route the JTAG TCK, TMS, TDI, and TDO signals as short, matched traces with a ground reference, and keep them away from high-speed I/O. Provide a dedicated ISP header footprint so the device can be reprogrammed in-system after assembly. Use thermal relief on the ground pads to aid soldering of the fine-pitch RQFP leads.
Do not assume the -20 speed grade meets a design originally built with a -15 part; the 20 ns pin-to-pin delay is 33% slower and may violate setup/hold margins. Also verify that the JTAG ISP chain is not disabled by the security bit, which permanently prevents reprogramming. Because the MAX 9000 family is obsolete, qualify incoming stock for authenticity and confirm the date code before committing to production.
