EPM7256AEFC100-10N

Complex Programmable Logic Devices Overview

The Altera EPM7256AEFC100-10N is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000A family. It features 256 macrocells organized into 16 Logic Array Blocks (LABs), providing approximately 5,000 usable gates. The device operates at a supply voltage of 3.3V (range 3.0V to 3.6V) and utilizes EEPROM technology for non-volatile configuration. It is housed in a 100-pin FineLine BGA package with an 84 I/O count. Key electrical parameters include a maximum propagation delay of 10 ns and a maximum operating frequency of 95.2 MHz. The commercial temperature range is specified from 0°C to +70°C.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity due to end-of-life status. Confirm RoHS compliance details as sources vary. Check humidity sensitivity handling requirements prior to assembly. Validate pinout compatibility with existing PCB footprints. Ensure programming tools support the MAX 7000A architecture.

Complex Programmable Logic Devices Selection Notes

Select this model when 256 macrocells are sufficient for the design logic. Choose the FC100 package for fine-pitch BGA mounting needs. Verify that the 3.3V I/O levels match system interfaces. Consider the 10 ns delay for timing-critical paths. Compare against EPM7256AE variants if different I/O counts or packages are required.

Complex Programmable Logic Devices Part Context

This part is part of the Altera MAX 7000A series, designed for cost-effective programmable logic solutions. It succeeded earlier MAX 7000 devices with improved speed and density. The EPM7256AEFC100-10N specifically targets applications requiring moderate logic density in a compact surface-mount package. It serves as a drop-in replacement for discrete gate arrays in many industrial designs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same package are limited due to EOL status. Evaluate EPM7256AE variants with different suffixes for package or speed changes. Consider Intel MAX 10 or Cyclone IV families for modern alternatives, noting architectural differences.
