EPM7256AEQC208-5N Présentation

The Intel (formerly Altera) EPM7256AEQC208-5N is a high-density CMOS Complex Programmable Logic Device (CPLD) from the MAX 7000A family, delivering 5,000 usable gates, 256 macrocells, and 164 user I/Os in a 208-pin PQFP package with -5 speed grade (5.5 ns pin-to-pin propagation delay). It operates from a 3.3 V core supply and supports in-system programmability via the IEEE Std. 1149.1 (JTAG) interface.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple PAL/GAL devices and high-density FPGAs in the programmable logic hierarchy: SPLD -> CPLD -> FPGA. Unlike SRAM-based FPGAs, MAX 7000A devices use EEPROM configuration cells that retain the bitstream without external memory, enabling instant-on behavior. Within the broader taxonomy of digital semiconductors, the EPM7256AEQC208-5N belongs to programmable logic -> logic ICs -> integrated circuits.

Key features include a maximum internal frequency of 172.4 MHz, a 4.5 ns registered propagation delay, and 16 dedicated input pins plus 164 bidirectional I/O pins. The architecture combines the FastTrack interconnect matrix with each macrocell containing a programmable AND/OR array, a product-term allocator, and a flipflop. The 3.3 V supply reduces power consumption by approximately 50% versus the legacy 5 V MAX 7000 family while preserving pin compatibility with existing designs.

Typical applications include bus interface bridging, glue-logic consolidation, peripheral I/O expansion, and control-state-machine implementation in telecom, industrial, and embedded systems. Designers use the part to replace discrete 74LS/74HC logic, reducing board area and BOM cost. The JTAG chain and built-in ISP (In-System Programmability) enable field firmware updates without removing the device from the board, a key advantage in deployed systems.

When designing with this device, ensure the Quartus II / MAX+PLUS II design software is used for fitting and that the JTAG pins (TDI/TDO/TMS/TCK) are pulled to valid logic levels through 10 kohm resistors. The PQFP-208 footprint requires a 0.5 mm lead pitch and IPC-7351 land patterns, and the device is rated for commercial temperature operation (0 C to +70 C).
