EPM3256AQC208-7 - Altera MAX 3000A CPLD | 256 Macrocells, 161 I/O, 208-PQFPDescription :
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.
