Typical Applications
EPM9560RC208-20N is suitable for 6 applications: Bus Interface and Protocol Bridging, Address Decoding and Chip-Select Generation, Power-Up Sequencing and Reset Control, Legacy System Glue Logic, Industrial Control Backplanes, Telecom and Networking Line Cards.
Bus Interface and Protocol Bridging
The EPM9560RC208-20N fits bus interface and protocol bridging because its 560 macrocells and 149 user I/O pins can implement wide address/data multiplexing and handshake logic in a single device. With a 20 ns pin-to-pin propagation delay and 5.0 V TTL/CMOS-compatible I/O, it bridges legacy 8/16-bit buses to peripherals without level shifters. The EEPROM configuration is live at power-up, so the bridge is active before the host processor releases reset, unlike SRAM-based FPGAs that need configuration time. A typical implementation places the CPLD between a host bus and a peripheral bus, using registered macrocells for synchronous handshaking; the trade-off is higher static power than modern low-voltage CPLDs, but no external configuration memory is required.
Recommended
Address Decoding and Chip-Select Generation
The EPM9560RC208-20N is used for address decoding and chip-select generation because its 560 macrocells provide ample product-term logic to decode wide address ranges and generate multiple active-low chip selects. The 20 ns tPD keeps decode latency low relative to legacy processor bus cycles, and the 5.0 V I/O directly drives TTL-level CS lines. Because the device is EEPROM-based, decode logic is valid immediately at power-up, which is critical for boot ROM and memory-mapped peripheral selection. Designers typically allocate one logic array block per peripheral group and use the programmable interconnect array to route decoded terms; the trade-off is that the fixed MAX 9000 interconnect is less flexible than an FPGA fabric, so decode equations should be planned to minimize cross-block routing.
Recommended
Power-Up Sequencing and Reset Control
The EPM9560RC208-20N suits power-up sequencing and reset control because its EEPROM configuration is instant-on, so sequencing logic is active the moment the 5.0 V rail is valid. The 560 macrocells can implement multi-rail enable sequencing, power-good gating, and reset stretching with counters and state machines, while the 149 user I/O pins drive enable pins across the board. The 20 ns tPD ensures reset de-assertion timing is deterministic. A common topology uses registered macrocells to hold peripherals in reset until all rails report good, then releases them in a defined order; the trade-off is that the CPLD itself must be powered from the earliest rail, so its supply sequencing must be considered in the power architecture.
Recommended
Legacy System Glue Logic
The EPM9560RC208-20N is widely used as legacy system glue logic because it consolidates dozens of discrete 74-series TTL packages into one 208-pin RQFP device. Its 560 macrocells and 12,000 usable gates absorb counters, shift registers, multiplexers, and state machines, reducing board area and part count. The 5.0 V I/O is directly compatible with legacy TTL and 5 V CMOS logic, so no level translation is needed. Because the device is non-volatile, there is no configuration PROM or boot delay. A typical migration replaces a board full of SSI/MSI logic with a single EPM9560RC208-20N; the trade-off is that the design becomes software-defined, so the JEDEC programming file must be managed and archived for production.
Recommended
Industrial Control Backplanes
The EPM9560RC208-20N fits industrial control backplanes because its 149 user I/O and 560 macrocells can implement backplane arbitration, slot addressing, and interrupt aggregation in one device. The 5.0 V I/O matches legacy industrial backplane signaling, and the 20 ns tPD supports deterministic response to backplane strobes. EEPROM non-volatility means the controller is ready immediately after power-up, which matters in factory automation where boot latency is unacceptable. A typical design uses the CPLD as a backplane controller that decodes slot selects and drives interrupt lines to a host CPU; the trade-off is that the MAX 9000 is a mature technology, so thermal and power budgets should account for 5.0 V static current in always-on backplanes.
Recommended
Telecom and Networking Line Cards
The EPM9560RC208-20N is used on telecom and networking line cards for control-plane glue logic, register interfaces, and LED/status aggregation. Its 560 macrocells implement multiple state machines for card bring-up, while the 149 user I/O pins interface to backplane control signals and local status LEDs. The 20 ns tPD supports the control-plane timing of legacy telecom buses, and 5.0 V I/O matches the signaling of older line-card backplanes. Because the device is EEPROM-based, card control logic is active at power-up without configuration from a host. A typical implementation uses the CPLD to manage card reset, slot ID, and hot-swap handshaking; the trade-off is that modern line cards favor low-voltage CPLDs, so this part is best reserved for maintenance of existing platforms.

Key Differentiators
- Lead-free RoHS-compatible package variant (vs EPM9560RC208-20C)
- 20 ns speed grade with 560 macrocells (vs EPM9560RC208-15N)
- EEPROM instant-on configuration (vs EPM9560RC208-10N)
Design Notes
The EPM9560RC208-20N is a 5.0 V EEPROM-based CPLD and draws static supply current even when logic is idle. Estimated: budget the 5.0 V rail for the device's quiescent and dynamic current, and decouple each VCC pin with a 0.1 uF ceramic capacitor placed within a few millimeters of the pin, plus a bulk 10 uF capacitor per device. Because the part is non-volatile, there is no configuration inrush, but the 5.0 V rail must be monotonic during power-up to guarantee correct EEPROM initialization.
Route the IEEE Std. 1149.1 JTAG signals (TCK, TMS, TDI, TDO) as short, controlled-impedance traces and keep TCK away from noisy switching nodes. Terminate TDI and TMS appropriately and provide a stable JTAG header for in-system programming. Place the 208-pin RQFP on a board with adequate thermal relief and keep the ground plane continuous under the device to minimize return-path inductance on the 149 user I/O lines.
A common pitfall with the EPM9560RC208-20N is assuming SRAM-FPGA-like flexibility: the MAX 9000 programmable interconnect array is fixed, so logic placement across logic array blocks affects achievable timing. Estimated: if a critical path crosses multiple blocks, the effective delay can exceed the 20 ns tPD specification. Plan decode and state-machine equations to localize logic within blocks, and verify timing with the vendor fitter report before committing the JEDEC file to production.
