EPM7256AEFC256-10N

Complex Programmable Logic Devices Overview

The Altera EPM7256AEFC256-10N is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000A family. It integrates 256 macrocells organized into 16 Logic Array Blocks (LABs), providing approximately 5,000 usable gates. The device features 164 I/O pins and utilizes an EEPROM memory technology for non-volatile configuration storage. It operates within a supply voltage range of 3.0 V to 3.6 V, typically at 3.3 V. The component supports a maximum operating frequency of 95.2 MHz with a typical propagation delay of 10 ns. It is housed in a 256-pin FineLine BGA package and is designed for commercial temperature ranges.

Complex Programmable Logic Devices Part Context

This part belongs to the Altera MAX 7000A series, a high-performance CPLD line known for fast throughput and ease of use. The 'EPM' prefix denotes the product family, while 'AE' indicates the specific generation variant. The suffix 'FC256' specifies the FineLine BGA package with 256 balls, and '-10' denotes the speed grade corresponding to 10 ns propagation delay. This series serves as a drop-in replacement for standard gate arrays and complex discrete logic circuits.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements are limited due to the specific package and I/O count. Engineers often consider the EPM7256AEFI256-10N or EPM7256AEFC256-5N for similar capacity but different speed grades or packages. For modern alternatives, Intel's MAX 10 or Cyclone IV families offer comparable logic density with enhanced features, though pin compatibility requires careful verification.
