EPM3256AQC208-7 - Altera MAX 3000A CPLD | 256 Macrocells, 161 I/O, 208-PQFP
The EPM3256AQC208-7 from Altera (now Intel) is a high-density Complex Programmable Logic Device (CPLD) from the MAX 3000A family. This device provides reliable, instant-on programmable logic for a wide range of digital control applications. With 256 macrocells and 161 I/O pins packaged in a 208-pin Plastic Quad Flat Pack, this CPLD delivers substantial logic capacity for implementing complex glue logic, state machines, and interface control functions with predictable timing and low power operation.Description
Important Correction: This device is a CPLD, not an FPGA. The EPM3256AQC208-7 is a high-capacity member of Altera's MAX 3000A CPLD family, utilizing EEPROM-based configuration technology that ensures non-volatile operation and instant startup. The device contains 256 macrocells organized into 16 Logic Array Blocks, providing approximately 5,000 gate equivalents of logic capacity. Operating at 3.3V with a commercial temperature range of 0°C to +70°C, this CPLD features fast 7.5ns pin-to-pin delays and supports maximum operating frequencies up to 126.6 MHz. Unlike FPGAs, this CPLD employs a deterministic interconnect architecture that guarantees consistent timing performance, making it particularly suitable for control-oriented applications, bus interfacing, and address decoding where timing predictability is essential.
