A CPLD (Complex Programmable Logic Device) is a programmable logic IC that combines multiple PAL-like logic blocks with a programmable interconnect matrix on a single die. In the broader hierarchy, a CPLD sits between simple PLDs (PAL/GAL) and FPGAs, offering non-volatile configuration, deterministic timing, and instant-on operation. MAX 9000 devices use EEPROM-based configuration, so they retain their logic after power-down without external configuration memory.
Key features include 560 macrocells organized into 20 logic array blocks, 12,000 usable gates, and 153 I/O pins supporting 3.3 V or 5 V LVTTL/LVCMOS levels. The 12 ns propagation delay and 125 MHz maximum clock rate make the device suitable for glue logic, bus interfacing, and state machine implementations where predictable timing matters more than raw gate count.
The MAX 9000 architecture uses a fast, predictable interconnect scheme with fixed pin-to-pin delays, unlike FPGAs where routing affects timing. Each macrocell contains a flip-flop with independent clock, clear, and preset, plus product-term logic for combinatorial functions. This architecture suits address decoding, bus arbitration, and interface bridging.
Typical applications include PCI/ISA bus glue logic, industrial control state machines, telecommunications line cards, and legacy system replacement. The 5 V core with 3.3 V I/O tolerance allows direct interfacing to both legacy 5 V TTL and modern 3.3 V logic.
When designing with this device, note that it is a legacy MAX 9000 part; verify availability and consider MAX II or MAX V migration for new designs. Provide adequate decoupling and observe the recommended power-up sequence.
This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a single reference for sourcing and migration decisions.

典型應用
EPM9560RC208-12 適用於 6 應用s: PCI Bus Glue Logic, Industrial Control State Machines, Telecommunications Line Cards, Legacy System Replacement, Test and Measurement Instrumentation, Military and Aerospace Avionics.
PCI Bus Glue Logic
The EPM9560RC208-12 fits PCI bus glue logic because its 12 ns pin-to-pin propagation delay and 125 MHz maximum clock rate satisfy PCI 33 MHz timing budgets, while its 153 I/O pins with 3.3 V or 5 V LVTTL/LVCMOS compatibility allow direct connection to both PCI and legacy buses. The device is typically placed between the PCI controller and peripheral devices to implement address decoding, wait-state generation, and interrupt routing. Its EEPROM configuration provides instant-on operation, which is essential because PCI bus initialization occurs immediately after power-up before any external configuration could be loaded. Unlike an FPGA, the MAX 9000's fixed interconnect guarantees deterministic timing, so worst-case delay is known at design time without place-and-route iteration.
推薦
Industrial Control State Machines
The EPM9560RC208-12 suits industrial control state machines because its 560 macrocells and 772 flip-flops can implement complex sequential logic, while the 12 ns propagation delay ensures fast response to sensor inputs. In a typical configuration, the CPLD implements multiple concurrent state machines for motor sequencing, safety interlocks, and fault detection, with 153 I/O pins handling limit switches, relays, and indicator outputs. The 5 V core with 3.3 V I/O tolerance allows direct interfacing to industrial 5 V sensors and 3.3 V controllers without level shifters. EEPROM non-volatile configuration means the logic is active within microseconds of power-up, critical for safety functions that cannot wait for configuration loading. The deterministic timing of the MAX 9000 architecture simplifies worst-case timing analysis for safety-critical control loops.
推薦
Telecommunications Line Cards
The EPM9560RC208-12 is used in telecommunications line cards for protocol conversion, timeslot interchange, and bus interfacing because its 125 MHz clock rate supports T1/E1 and SONET overhead processing, and its 153 I/O pins accommodate multiple serial and parallel interfaces. The device typically sits between the line interface unit and the backplane, implementing framer glue logic, clock domain crossing, and status register aggregation. The 12 ns propagation delay keeps setup and hold margins comfortable at telecom clock rates, while the 5 V core with 3.3 V I/O compatibility allows direct connection to both legacy 5 V telecom components and modern 3.3 V DSPs. EEPROM configuration ensures the line card is operational immediately after power-up, avoiding the configuration delay that would disrupt telecom synchronization.
推薦
Legacy System Replacement
The EPM9560RC208-12 serves as a replacement for obsolete discrete logic in legacy systems because its 560 macrocells can absorb dozens of 74-series TTL packages, reducing board area and power while preserving the original 5 V signaling. Engineers use it to consolidate address decoders, bus transceivers, and glue logic into a single 208-pin RQFP device, often as a drop-in replacement for older MAX 9000 or MAX 7000 designs. The 3.3 V or 5 V I/O compatibility allows direct connection to existing 5 V backplanes without level shifters. Because the device is EEPROM-based, it retains its configuration without a battery, unlike SRAM-based FPGAs, which simplifies long-term maintenance of legacy equipment.
推薦
Test and Measurement Instrumentation
The EPM9560RC208-12 is used in test and measurement instrumentation for trigger logic, timing generation, and data acquisition control because its 12 ns propagation delay and 125 MHz clock rate provide precise timing resolution, and its 153 I/O pins can interface to multiple ADCs, DACs, and digital I/O channels. In a typical instrument, the CPLD implements programmable trigger sequences, sample clock generation, and FIFO control, with deterministic timing that ensures repeatable measurements. The 5 V core with 3.3 V I/O compatibility allows direct interfacing to both legacy 5 V analog front ends and modern 3.3 V data converters. EEPROM configuration provides instant-on operation, so the instrument is ready to measure immediately after power-up without a configuration delay.
推薦
Military and Aerospace Avionics
The EPM9560RC208-12 is used in avionics and military systems for interface bridging, bus control, and discrete logic consolidation because its EEPROM configuration is immune to radiation-induced configuration loss that affects SRAM-based FPGAs, and its 5 V core with 3.3 V I/O compatibility interfaces to legacy avionics buses. The 12 ns propagation delay and 125 MHz clock rate support MIL-STD-1553 and ARINC 429 protocol glue logic, while the 153 I/O pins accommodate multiple bus interfaces. The device's non-volatile configuration ensures the system is operational immediately after power-up, critical for flight-control and mission systems that cannot tolerate configuration delays. Note that commercial temperature grade parts require thermal analysis for extended-temperature environments.

設計說明
Provide adequate decoupling for the EPM9560RC208-12's 5 V core and I/O rails. Place at least one 0.1 uF ceramic capacitor per power pin pair, plus a 10 uF bulk capacitor near the device. The MAX 9000 family draws significant transient current during logic switching; insufficient decoupling causes ground bounce and unreliable operation. Estimated: at 125 MHz with 153 I/O switching, transient current can exceed several hundred milliamps, so low-ESR capacitors and short, wide traces to the power plane are essential.
The 208-pin RQFP package uses a 0.50 mm terminal pitch, requiring fine-pitch PCB fabrication and assembly. Use a solder mask defined (SMD) pad geometry per the manufacturer's recommended land pattern, and ensure the stencil aperture is sized for adequate paste volume. Route I/O traces away from the package corners to avoid solder bridging. Because the device is obsolete, verify that your assembly house can source the package and has experience with 0.50 mm pitch RQFP.
The EPM9560RC208-12 is an obsolete MAX 9000 device; do not design it into new products without a migration plan. When replacing with a different speed grade (e.g., -10 or -20), re-run static timing analysis because the propagation delay changes. When migrating to MAX II or MAX V, note that these use different packages and I/O voltages, requiring PCB redesign. Always verify the configuration file is compatible with the target device density and speed grade.
