What is a CPLD? A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic IC that combines multiple PAL/PLA-style logic blocks with a central interconnect matrix. CPLDs are used for glue logic, bus interfacing, state-machine control, and address decoding - typically chosen over discrete TTL/CMOS when the design must be reconfigured, kept compact, or shipped across product variants. Within the programmable-logic hierarchy, CPLDs sit below FPGAs in density but offer deterministic timing, instant-on from non-volatile memory, and high I/O counts per dollar.
Key features of the EPM9560RC304-2N include a maximum pin-to-pin propagation delay (tPD) on the order of -2 speed-grade performance, in-system programmability via the IEEE 1149.1 JTAG interface, and a wide operating voltage range centred at 5.0V. The device supports multiple I/O standards and provides programmable pull-ups, slew-rate control, and per-pin output enable.
Architecturally, the MAX 9000 family partitions the 560 macrocells across Logic Array Blocks (LABs) wired by a FastTrack interconnect, delivering predictable timing and uniform routing delay regardless of placement. The 304-pin package provides the largest pin-count option in the family, maximising user I/O for high-density bus-interface or bus-multiplexing applications.
Typical applications include telecommunications backplane glue logic, industrial-control address decoding, peripheral interface bridging (PCI-to-ISA, memory-to-bus arbitration), and high-pin-count state-machine controllers in embedded systems. The instant-on non-volatile configuration suits safety-critical and power-sequenced systems.
Designers should note that the 304-pin package is the largest pin-count in the MAX 9000 family; PCB layout requires careful power/ground planning and thermal relief. The 5.0V core is incompatible with 3.3V-only systems unless level-shifters are used on every I/O.

典型應用
EPM9560RC304-2N 適用於 6 應用s: Telecommunications Backplane Glue Logic, PCI-to-ISA Bus Bridge, Industrial Control Address Decoding, High-Pin-Count State Machine Controllers, Memory-to-Bus Arbitration Logic, Legacy Peripheral Interface Bridging.
Telecommunications Backplane Glue Logic
The EPM9560RC304-2N's 560 macrocells and 304-pin package make it ideal for telecom backplane glue logic where dozens of address, control, and interrupt signals must be arbitrated and re-mapped. Its deterministic tPD timing and non-volatile instant-on configuration suit power-sequenced line-card designs. Placed between the host ASIC and downstream PHYs, it implements bus multiplexers, address latches, and protocol converters. Compared to discrete 74-series logic, one MAX 9000 device replaces dozens of packages, saving board area on dense backplanes.
推薦
PCI-to-ISA Bus Bridge
The EPM9560RC304-2N was widely used as a PCI-to-ISA bridge controller in legacy industrial motherboards and embedded PCs. Its 12,000 usable gates and 304-pin I/O count accommodate the full 32-bit PCI and 16-bit ISA bus multiplexers, plus interrupt steering and DMA arbitration logic. The non-volatile configuration loads instantly at power-up, eliminating boot-delay logic. Modern systems replace this with purpose-built bridge ICs, but legacy boards still depend on the MAX 9000 for spares and repairs.
推薦
Industrial Control Address Decoding
The EPM9560RC304-2N excels at complex address decoding in PLC and industrial controller backplanes where 20-30 chip-select signals must be generated from a wide address bus. Its 560 macrocells handle full decode trees, comparator-based bank selection, and timing-skew compensation in a single device. The JTAG (IEEE 1149.1) interface supports boundary-scan testing, simplifying in-system fault isolation. Compared to discrete decoder ICs, the MAX 9000 reduces part count and enables late-stage design changes via re-programming.
推薦
High-Pin-Count State Machine Controllers
For complex finite-state machines controlling multi-axis motor drivers, robotic arm sequencers, or test-stand automation, the EPM9560RC304-2N's 560 macrocells and 200+ user I/Os provide ample room for state encoding, mode selection, and fault-handling logic. Its instant-on non-volatile configuration boots in microseconds without external boot memory. Used in industrial automation rigs, it replaces discrete flip-flop/PLA designs while keeping timing fully deterministic - critical for safety interlock sequencing.
推薦
Memory-to-Bus Arbitration Logic
The EPM9560RC304-2N's high I/O count accommodates full multi-master bus arbitration, including request/grant pairs, address muxing, and wait-state insertion for shared memory subsystems. Its deterministic propagation delay supports real-time arbitration without metastability risk. Used in shared-memory multiprocessor systems and dual-ported memory controllers, it consolidates discrete arbiter ICs and grant-priority logic into a single reconfigurable device, easing design migration across product variants.
推薦
Legacy Peripheral Interface Bridging
The EPM9560RC304-2N bridges legacy peripherals (parallel-port printers, ISA cards, SCSI controllers) to modern host buses in industrial PCs and test instruments. Its 304 pins handle full 8/16/32-bit parallel interfaces, control signals, and interrupt steering in a single device. The MAX 9000's non-volatile instant-on configuration is well-suited to embedded applications requiring deterministic boot behaviour. Compared to modern FPGA-only designs, the MAX 9000 remains preferred for its simplicity and predictable timing.

主要差異化特點
- Highest I/O count in the MAX 9000 family (對比EPM9560RC240-20)
- Mid-band speed grade (-2) for balanced timing margin (對比EPM9560RC304-15N)
- Non-volatile instant-on configuration (對比MAX V/MAX 10 CPLDs)
設計說明
The 304-pin plastic carrier is the largest pin-count package in the MAX 9000 family, requiring at least a 4-layer PCB with continuous power and ground planes for noise suppression. Per the MAX 9000 datasheet, every VCCINT and VCCIO pin must be decoupled with a 0.1uF ceramic capacitor placed within 3 mm of the pin. Add bulk tantalum or polymer capacitors (10-47uF) near the device to handle simultaneous-switching-current (SSI) transients.
Use the Quartus Prime MAX+PLUS II fitter report to identify the actual pin assignments before PCB layout. The MAX 9000 family supports pin-locking, but the fitter may swap signals if the design exceeds device resources. Always reserve 10-15% spare macrocells for late-stage ECO changes. For high-speed signals, place slew-rate control bits at 1 (slow) on outputs driving long traces or backplane connectors to reduce EMI.
Estimated: power consumption at 304 pins switching simultaneously can reach 1.5-2.0 W worst-case. The 304-pin plastic carrier has theta_JA around 30-40 C/W without airflow, so a 1 sq-inch copper pour on top/bottom planes is recommended. Do not mix 5.0V VCCIO with 3.3V peripherals without level-shifters - the MAX 9000 I/O is 5.0V-tolerant only on the input side when configured for 5.0V operation. Always check JTAG chain integrity by reading the device ID before programming.
合規資訊
Compliance status not provided in the verified web data. The MAX 9000 family pre-dates widespread RoHS adoption - many EPM9560 variants are non-RoHS (SnPb finish). Newer '-N' suffix variants are typically lead-free. Confirm with distributor documentation before lead-free assembly.
