EPM7256AEFC100-10

Complex Programmable Logic Devices Overview

The Altera EPM7256AEFC100-10 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 offers 84 I/O pins and operates on a 3.3V supply voltage with a range of 3.0V to 3.6V. It utilizes non-volatile EEPROM technology for configuration storage. The component is housed in a 100-pin FineLine PBGA package with dimensions of 10x10mm. It supports System In-Programmability (SIP) via JTAG and functions within an industrial temperature range of -40°C to +85°C.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity as this part may be discontinued or obsolete. Confirm RoHS compliance status, as some variants are marked non-compliant. Ensure handling procedures account for moisture sensitivity level 3 requirements during soldering. Validate that the specific suffix corresponds to the required package and temperature grade.

Complex Programmable Logic Devices Selection Notes

Select this model when 256 macrocells and 84 I/Os are sufficient for the design. Choose the PBGA100 package for high-density surface-mount applications requiring a 10x10mm footprint. Ensure the design requires 3.3V logic levels with 5V input tolerance. Consider alternatives if higher gate counts or different pinout configurations are necessary.

Complex Programmable Logic Devices Part Context

This CPLD is part of the Altera MAX 7000A series, designed for cost-effective programmable logic solutions. It succeeds earlier MAX 7000 variants with improved speed and density. The EPM7256AEFC100-10 specifically denotes the 10ns speed grade and FC100 package code. It serves as a drop-in replacement for many fixed-function logic chips in legacy designs.

Complex Programmable Logic Devices Replacement Considerations

Direct substitutes include other MAX 7000A devices with similar macrocell counts, such as EPM7256AEFI100-10 (FBGA package) or EPM7256AETC100-10 (TQFP package). Verify pin compatibility and electrical characteristics before substitution. Check manufacturer documentation for obsolescence notices and recommended new product lines.
