EPM7256AEQC208-10

Complex Programmable Logic Devices Overview

The Altera EPM7256AEQC208-10 is a Complex Programmable Logic Device (CPLD) belonging to the MAX 7000A family. It features 256 macrocells, 5,000 usable gates, and 16 Logic Array Blocks (LABs). The device provides 164 I/O pins within a 208-pin Plastic Quad Flat Package (PQFP). It operates on a single 3.3V supply voltage with a maximum propagation delay of 10 ns and a maximum operating frequency of 125 MHz. Non-volatile EEPROM storage allows for in-system programming.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm package integrity and pin alignment prior to assembly. Ensure design compatibility with 3.3V logic levels and verify that the 10 ns timing specification meets system requirements.

Complex Programmable Logic Devices Selection Notes

Select this model when 256 macrocells and 164 I/Os are required in a 208-pin form factor. Compare against the EPM7256S series if 5V operation is necessary instead of 3.3V. Verify that the 10 ns speed grade satisfies the target clock frequencies for the specific application logic.

Complex Programmable Logic Devices Part Context

This component is part of the Altera MAX 7000A CPLD family, which succeeded the original MAX 7000 series. The 'AE' suffix denotes the enhanced 3.3V variant. It serves as a high-density solution for legacy systems requiring non-volatile programmability without the complexity of FPGA architectures.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements may be limited. Evaluate the EPM7256SQC208-10N for similar functionality but note the difference in operating voltage (5V vs 3.3V). Cross-reference with Intel's current portfolio for modern equivalents if long-term supply assurance is critical.
