Typical Applications
EPM9560RI304-20N is suitable for 7 applications: Legacy 5V Bus Address Decoding, Telecom Backplane Glue Logic, Industrial Control Logic Consolidation, Peripheral Multiplexing and Chip-Select Generation, Avionics and Defense Legacy Sustainment, Medical Imaging Backend Interfaces, Test and Measurement Instrumentation.
Legacy 5V Bus Address Decoding
The EPM9560RI304-20N is well suited to legacy 5V address decoding in ISA, VME, and PC/104 bus systems. With 212 user I/O and 560 macrocells, it can decode wide address ranges, generate chip-select signals, and replace multiple 74LS/74F-series decoder packages on a single chip. The 20ns tPD comfortably meets ISA bus timing and slower VME cycles. Programming is via JTAG using MAX+PLUS II, and the part retains configuration in EEPROM without external boot memory.
Recommended
Telecom Backplane Glue Logic
In telecom backplanes, the EPM9560RI304-20N consolidates scattered 5V glue logic such as bus arbiters, interrupt controllers, and reset sequencers. Its 304-pin RQFP delivers 212 I/O to handle H.110 CT bus signals, TDM clocks, and front-panel LEDs without multiplexing. The deterministic FastTrack interconnect provides fixed propagation delay regardless of placement, simplifying static timing closure. Industrial temperature grade supports outside-plant enclosures when paired with conformal coating.
Recommended
Industrial Control Logic Consolidation
Factory automation controllers benefit from the EPM9560RI304-20N's high I/O count and 5V tolerance for replacing discrete 74HC/74AHCT logic. It can implement motor-control state machines, PLC scan engines, and safety-interlock logic in a single device. EEPROM-based configuration means instant-on at power-up, eliminating FPGA configuration latency in safety paths. The 304-pin RQFP provides thermal mass and is suitable for enclosed industrial cabinets with adequate forced-air cooling.
Recommended
Peripheral Multiplexing and Chip-Select Generation
The 212 I/O of the EPM9560RI304-20N enables wide peripheral multiplexing for embedded motherboards, where it can drive multiple memory banks, generate read/write strobes, and arbitrate DMA requests. Compared to discrete 74LS138/74LS139 decoders, one EPM9560RI304-20N reduces board area by 70 percent and simplifies rework when address maps change. The 20ns tPD adds 1-2 wait states for fast SRAM at 33MHz but is invisible at slower ISA bus speeds.
Recommended
Avionics and Defense Legacy Sustainment
Avionics and defense sustainment programs that designed in the EPM9560RI304-20N in the late 1990s continue to procure it for line-replaceable unit (LRU) repairs. With military-qualified screening available through broker channels, the device supports DO-254 DAL-C and DAL-D designs that have completed certification. The deterministic 20ns timing eases DO-330 IP reuse verification. Intel's PCN obsoletions push sustainment programs to broker sourcing with lifetime buys.
Recommended
Medical Imaging Backend Interfaces
The EPM9560RI304-20N is used in legacy ultrasound and CT imaging systems where it interfaces parallel ADCs to DSP processors and reconstructs image pipelines. Its 212 I/O accommodates wide data buses from 12-14-bit ADCs, and the 5V supply matches vintage analog front ends. EEPROM retention eliminates firmware boot delays critical to patient throughput. Designers transitioning to new platforms should consider MAX V or MAX 10 with 3.3V I/O and LVDS support.
Recommended
Test and Measurement Instrumentation
Bench-top instruments such as logic analyzers and protocol testers use the EPM9560RI304-20N for pattern generation, channel multiplexing, and trigger sequencing. Its deterministic 20ns timing allows precise trigger placement, and 212 I/O supports parallel test points. The JTAG ISP interface simplifies firmware updates during development. For new designs, modern MAX 10 CPLDs add analog blocks and faster I/O but require 3.3V supply migration.

Key Differentiators
- Higher logic density versus 240- and 208-pin siblings (vs EPM9560RI240-20N)
- Slowest but lowest-cost speed grade in the EPM9560 family (vs EPM9560RI304-15N)
- Industrial temperature grade option (vs EPM9560RC304-20)
Design Notes
Estimated: at 100 MHz toggle rate with 50 percent I/O switching and 25 pF load, the EPM9560RI304-20N dissipates roughly 0.6-1.2 W. The 304-pin RQFP has typical theta_JA of approximately 25-30 C/W on a 4-layer JEDEC test board, resulting in a junction temperature rise of 15-36 C above ambient. For industrial enclosures at 70 C ambient, supply adequate forced-air cooling and provide a 2-3 square-inch copper land pattern under the exposed die pad area to keep Tj below 125 C.
The 304-pin RQFP has a 0.5 mm pitch and a large body (approximately 34x34 mm). Use a 4-layer PCB with dedicated VCC and GND planes to minimize supply bounce during simultaneous I/O switching. Place decoupling capacitors (0.1 uF X7R plus 10 uF tantalum) within 5 mm of every VCCINT and VCCIO pin cluster. JTAG chain integrity requires a 4.7 kohm pull-up on TCK and TMS to VCCIO if the download cable is not actively driving them.
Do not confuse the EPM9560RI304-20N with the EPM9560RC304-20N - the I vs C prefix indicates Industrial (I) versus Commercial (C) temperature grade. The -20N suffix in some datasheets denotes speed grade, but the package suffix N here refers to the industrial temperature. Always verify the full ordering code against your thermal requirements. Programming the wrong grade does not damage the silicon but causes timing failures at temperature extremes.
Compliance Information
This is a legacy Altera MAX 9000 family part from the late 1990s. RoHS, REACH, lead-free, and halogen-free status were not declared in the verified distributor data and must be confirmed per lot with the broker when required for EU-marketed end products.
