Typical Applications
EPM9560RI304 is suitable for 6 applications: Industrial Control Backplane Glue Logic, Telecom Line-Card Interface Logic, Legacy System Maintenance and Repair, Test and Measurement Instrumentation, Military and Aerospace 5 V Logic Retrofit, Industrial Bus Protocol Bridging.
Industrial Control Backplane Glue Logic
The EPM9560RI304 fits industrial control backplanes because its 560 macrocells and 216 user I/O pins can absorb the address decoding, chip-select generation, and bus arbitration logic that would otherwise require dozens of discrete 74-series devices. Its 5.0 V I/O interfaces directly to legacy 5 V backplane transceivers without level shifters, and the 20 ns tPD keeps combinatorial decode paths within a single 50 MHz bus cycle. The industrial -40C to +85C rating supports factory-floor cabinets where ambient temperatures routinely exceed commercial limits. Because the MAX 9000 EEPROM configuration is non-volatile, the device is operational immediately after power-up with no boot PROM, which is critical for backplanes that must not hang during initialization.
Recommended
Telecom Line-Card Interface Logic
Telecom line cards use the EPM9560RI304 to implement PCM highway timeslot assignment, HDLC framing glue, and register access logic between line interface units and backplane buses. The 560-macrocell density accommodates multiple channel state machines in one device, while the 304-pin RQFP package provides enough I/O for wide parallel buses. The 5.0 V supply matches the legacy telecom chassis rails, and the 20 ns propagation delay supports the timing budget of E1/T1 and STM-1 tributary interfaces. Non-volatile EEPROM configuration means the line card returns to service instantly after a power cycle, avoiding the reconfiguration delay of SRAM-based FPGAs in high-availability central-office equipment.
Recommended
Legacy System Maintenance and Repair
The EPM9560RI304 is widely used in legacy system maintenance because it is the industrial-temperature MAX 9000 device most often found in fielded equipment that is still in service. When an original device fails, the EPM9560RC304-20 provides a pin-identical commercial-grade substitute for indoor racks, while the EPM9560RC304-15N offers a lead-free option for RoHS-restricted repair depots. The 304-pin RQFP footprint is identical across these variants, so no PCB rework is required. Because the MAX 9000 family is obsolete, repair organizations should qualify a drop-in variant and stock it before broker inventory is exhausted.
Recommended
Test and Measurement Instrumentation
Test and measurement instruments use the EPM9560RI304 for trigger logic, pattern generation, and instrument bus control where deterministic timing matters more than raw gate count. The MAX 9000 architecture routes all signals through the Programmable Interconnect Array, giving fixed, predictable propagation delays that simplify timing analysis in measurement front ends. The 20 ns tPD and 560 macrocells allow multi-channel trigger state machines to be implemented in a single device, and the 5.0 V I/O drives legacy instrument backplanes directly. Non-volatile configuration ensures the instrument boots into a known logic state without a configuration PROM, which reduces bill-of-materials cost and boot time.
Recommended
Military and Aerospace 5 V Logic Retrofit
Military and aerospace programs that still specify 5.0 V logic use the EPM9560RI304 for interface consolidation and discrete logic replacement. The industrial temperature grade covers many sheltered avionics and ground-equipment environments, and the EEPROM configuration is immune to the single-event upset behavior of SRAM-based FPGAs in radiation environments. The 304-pin RQFP package provides the I/O count needed for wide avionics data buses, and the IEEE Std. 1149.1 JTAG interface supports boundary-scan testing required by many defense contracts. Designers should confirm the specific program's temperature and screening requirements, since the RI304 is industrial grade rather than full military temperature range.
Recommended
Industrial Bus Protocol Bridging
The EPM9560RI304 is used to bridge between dissimilar industrial bus protocols such as VME, ISA, and proprietary backplanes, where the CPLD translates address, data, and control signaling between domains. Its 560 macrocells can hold multiple protocol state machines simultaneously, and the 216 user I/O pins accommodate wide address and data buses without external multiplexing. The 5.0 V I/O matches legacy bus transceivers, and the 20 ns tPD keeps bridge latency low enough for real-time control loops. Because the MAX 9000 configuration is non-volatile, the bridge comes up in a defined state at power-on, avoiding the bus contention risk that can occur when an SRAM FPGA configures after the host bus is already active.

Key Differentiators
- Industrial temperature grade (vs EPM9560RC304-20)
- Non-volatile EEPROM configuration (vs EPM9560RC304-15)
- 560-macrocell density in a 304-pin package (vs EPM9560RI240-20)
- 5.0 V I/O compatibility (vs EPM9560RC304-10)
Design Notes
Decouple every VCC pin of the EPM9560RI304 with a 0.1 uF ceramic capacitor placed as close to the pin as possible, plus at least one bulk 10 uF capacitor per device. The MAX 9000 family draws transient current during EEPROM configuration and high-speed switching, and inadequate decoupling causes configuration failures and intermittent logic errors. Estimated: at 5.0 V and a typical 100 mA dynamic current, each 0.1 uF capacitor supplies roughly 0.5 nC of charge per switching event, so multiple capacitors are required across the 304-pin package.
Route the JTAG signals (TCK, TMS, TDI, TDO) as short, matched traces with a solid ground reference, and keep TCK away from high-speed data buses to avoid clock noise coupling into the configuration interface. Place the JTAG header close to the device so the programming cable does not introduce excessive stub length. For the 304-pin RQFP package, use a thermal-relief pattern on the ground pads and verify solder-joint integrity with X-ray inspection, since fine-pitch gull-wing leads are prone to bridging.
Do not assume the EPM9560RI304 is still in production: the MAX 9000 family is obsolete, so new designs should migrate to a modern CPLD family such as MAX V. When substituting a commercial-grade EPM9560RC304 variant for the industrial EPM9560RI304, verify that the end application never exceeds 0C to +70C, because the commercial grade is not qualified for the industrial -40C to +85C range. Also confirm the configuration file is compatible across speed grades, since timing closure may change when moving from -20 to -15 or -10 devices.
