Complex Programmable Logic Devices Procurement Notes

Verify component authenticity and datasheet revision alignment before procurement. Confirm that the specific ordering suffix corresponds to the required package and temperature grade. Ensure compliance with relevant regulatory standards for the intended deployment environment.

Complex Programmable Logic Devices Selection Notes

Select this model when 256 macrocells and 164 I/O pins are required within a 144-pin TQFP package. Consider the 5.0 ns speed grade for timing-critical paths. Evaluate power consumption requirements as the device supports programmable power-saving modes for individual macrocells.

Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000B family, which offers pin-compatibility with the 5.0-V MAX 7000S and 3.3-V MAX 7000A families. The architecture supports migration across densities using SameFrame pin-outs in BGA packages, though this specific variant uses a TQFP package.

Complex Programmable Logic Devices Replacement Considerations

Pin-compatible alternatives within the same family include EPM7256B variants with different speed grades or package options. Cross-family replacement requires verification of voltage levels and I/O compatibility.
