MPN: EPM9560RI304-20C ✗ Cuối đờiEPM9560RI304-20C Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that combines multiple PAL/GAL-style macrocell arrays on a single die, connected by a programmable interconnect matrix (the Multiple Array MatriX, or MAX, architecture used here). Unlike FPGAs, which use RAM-based lookup tables and require external boot memory, CPLDs retain their configuration in on-chip EEPROM and provide deterministic, glitch-free propagation delays. MAX 9000 sits in Altera's taxonomy as a high-density 5V legacy CPLD, between MAX 7000 (mid-density 5V) and FLEX 10K (early SRAM-based FPGA).
Key features include third-generation MAX architecture for predictable timing, 5.0 V in-system programmability through JTAG (IEEE 1149.1), 16 logic array blocks, 36 macrocells per LAB, fast parallel expansion across multiple devices, and pin-compatible speed grades (-20, -15, -10) within the EPM9560 family. The 304-pin RQFP provides the maximum I/O count (212) for the EPM9560 die, allowing it to replace multiple discrete logic ICs in glue-logic, bus-interface, and state-machine roles.
The EPM9560RI304-20C uses CMOS EEPROM process technology with a multi-array matrix interconnect that distributes signals across 16 LABs in a predictable, deterministic-timing fabric. Designers can synthesize state machines, decoders, and bus interfaces using Altera/Intel Quartus II (legacy MAX+PLUS II) software, then program the device in-system through the JTAG pins without removing it from the board. This makes it well-suited for long-life industrial equipment where field upgrades are rare but reliability is critical.
Typical applications include industrial control glue logic, telecommunications bus interfaces, ASIC prototyping, peripheral controllers, and legacy 5V system designs. It is also used as a bus arbiter or address decoder where deterministic 23.6 ns propagation delay and 5V tolerance are required.
When designing with the EPM9560RI304-20C, ensure the JTAG chain (TCK, TMS, TDI, TDO) is properly terminated and that unused I/O pins are left floating or grounded per the MAX 9000 datasheet to minimize inrush during ISP. Note that newer 3.3V-only designs should migrate to MAX II or MAX V families instead.

Ứng dụng tiêu biểu
EPM9560RI304-20C phù hợp cho 6 Áp dụngs: Industrial Control Glue Logic, Telecommunications Bus Interface, ASIC Prototyping, Legacy 5V System Glue Logic Replacement, Peripheral Controller for Printers and Storage, Address Decoder and Bus Arbiter.
Industrial Control Glue Logic
The EPM9560RI304-20C is widely used as glue logic in industrial controllers because of its 212 user I/O pins and deterministic 23.6 ns pin-to-pin delay, which lets a single device replace multiple 74LS/74HC discrete logic ICs. Its 5.0 V tolerance and 0C to +70C commercial operating range fit factory-floor backplanes and PLC I/O cards that still rely on 5V logic. The in-system programmable JTAG interface (IEEE 1149.1) lets field engineers update state-machine firmware without removing the board. With 560 macrocells and 16 LABs, the device can absorb entire bus-state decoders and interrupt-arbiter trees in one chip, reducing BOM count and improving long-term reliability.

Telecommunications Bus Interface
The EPM9560RI304-20C suits legacy telecom backplane designs because of its 560 macrocells and 212 I/O pins, which can implement full bus-interface logic for parallel TDM or proprietary data buses. Its 5V I/O directly drives TTL-level telecom backplanes without level shifters, and the JTAG (IEEE 1149.1) ISP interface simplifies board-level test and field updates. With 23.6 ns propagation delay and 100 MHz internal frequency, it can handle address decoding, bus arbitration, and timing-and-control functions for medium-speed telecom peripherals. The 304-pin RQFP package supplies the I/O density required for multi-bus bridges.
Được đề xuất
ASIC Prototyping
The EPM9560RI304-20C is used for ASIC prototyping because it offers 12,000 usable gates and 560 macrocells, enough to emulate mid-complexity custom ASICs at 5V before committing to a foundry run. Its EEPROM non-volatile configuration means prototypes survive power cycling with no boot memory, which matches real ASIC behavior more closely than SRAM-based FPGAs. With deterministic 23.6 ns propagation delay and 100 MHz internal clock, engineers can validate timing-sensitive control logic. The JTAG ISP chain supports fast design-turn loops during early silicon bring-up.
Được đề xuất
Legacy 5V System Glue Logic Replacement
The EPM9560RI304-20C is ideal for sustaining legacy 5V systems where 3.3V-only CPLDs cannot be used. Its 5.0 V VCC tolerance directly interfaces with legacy TTL peripherals, memory, and bus transceivers without external level shifting. With 560 macrocells, the device can absorb whole sections of discrete 74-series logic, reducing board area and improving serviceability through JTAG-driven in-system updates. The 23.6 ns propagation delay and 100 MHz internal frequency cover most glue-logic timing budgets, and the 304-pin RQFP provides 212 I/Os for wide parallel interfaces in legacy backplanes.

Peripheral Controller for Printers and Storage
The EPM9560RI304-20C is deployed as a peripheral controller in legacy printers and storage subsystems because its 212 I/O pins and 560 macrocells can drive parallel ATA/IDE buses, stepper-motor control logic, and encoder interfaces simultaneously. Its deterministic 23.6 ns tpd ensures glitch-free state-machine transitions needed for motor commutation, while its 5V tolerance matches the legacy driver stage. JTAG ISP allows firmware updates across long product lifecycles. The 100 MHz internal frequency supports high-rate DMA-style peripheral transfers without external logic.
Được đề xuất
Address Decoder and Bus Arbiter
The EPM9560RI304-20C excels as a central address decoder and bus arbiter in multi-master 5V systems. Its 23.6 ns pin-to-pin propagation delay is fast enough to qualify as a 1-cycle wait-state decoder on most 25-33 MHz 5V microprocessors and DSPs, and 212 I/Os cover wide address and chip-select fanouts. With 16 LABs, complex priority encoders and round-robin arbiters fit comfortably. The EEPROM non-volatile configuration means no boot sequence is needed at power-up, which is critical for deterministic bus responses in industrial- and defense-grade 5V systems.

Ghi chú thiết kế
The EPM9560RI304-20C is a 5V-only part - applying 3.3V signals to its I/O without proper level translation can damage inputs or cause logic-high misreads. Confirm all driving logic is true 5V TTL-compatible. Unused I/O pins must be left floating or tied to GND through a resistor as specified in the MAX 9000 datasheet to minimize inrush during ISP programming. Decoupling: place 0.1uF ceramic bypass caps close to every VCC/GND pair on the 304-pin RQFP, plus a 10uF bulk tantalum near the device.
JTAG chain integrity is critical for ISP. Keep TCK trace length-matched and short (<2 inches if possible), with a 10k pull-up on TMS and TDI. Add series termination (33 ohm) on TCK if the chain exceeds 4 inches. For multi-device JTAG chains, place the EPM9560RI304-20C so that TDO feeds TDI of the next device without stubs. Maintain solid ground plane under the 304-pin RQFP to reduce switching noise coupling into analog sections of the board.
Estimated: at 100 MHz internal frequency, the EPM9560RI304-20C core draws up to ~250 mA from 5V VCC, so design the 5V regulator for at least 1.5x headroom (~400 mA). Use a low-impedance 5V plane rather than a trace, and add a 10uF tantalum plus 0.1uF ceramic at each VCC pin. During ISP programming, inrush current can spike - ensure bulk capacitance is adequate to hold VCC above 4.75V (the minimum operating voltage).
The 304-pin RQFP package has a theta_JA around 35-40 C/W. In a well-ventilated industrial enclosure at 70C ambient, the junction stays below 100C for typical toggle rates. In sealed or stacked assemblies, derate the toggle rate or add forced-air cooling. For long-life designs, keep junction temperature below 100C to maximize EEPROM write-cycle endurance and device MTBF.
