Complex Programmable Logic Devices Procurement Notes

Verify component authenticity due to end-of-life status. Confirm RoHS compliance as listings vary between compliant and non-compliant variants. Check humidity sensitivity handling requirements prior to assembly. Ensure design compatibility with 3.3V logic levels and JTAG programming interfaces.

Complex Programmable Logic Devices Selection Notes

Select this model when 256 macrocells are sufficient for the target logic density. The TQFP-100 package suits applications requiring moderate pin counts with surface-mount constraints. Verify that the 5.5 ns delay meets timing requirements for the specific clock domain. Consider pin-out compatibility if replacing older MAX 7000 series devices.

Complex Programmable Logic Devices Part Context

This part belongs to the Altera MAX 7000A series, designed as a high-performance, low-power CPLD. It serves as a successor to the MAX 7000S family, offering improved speed and lower voltage operation while maintaining pin compatibility with certain legacy packages. The EPM7256 variant represents a mid-range density option within the family.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements may exist within the MAX 7000B or MAX 7000S families, though voltage and speed specifications differ. Verify functional equivalence regarding I/O drive strength and logic architecture before substitution.
