Complex Programmable Logic Devices Procurement Notes

Verify component authenticity due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level handling requirements during assembly. Check for available datasheets confirming pinout and electrical characteristics for the specific UCSP-49 package variant.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 3.3V logic levels with high I/O density in a compact footprint. Ensure compatibility with existing 5V-tolerant peripherals if interfacing directly. Consider the 10ns speed grade against system timing requirements compared to faster MAX 7000S variants.

Complex Programmable Logic Devices Part Context

Part of the Altera MAX 7000B family, designed as a low-power, high-performance CPLD. It serves as a successor to the 5V MAX 7000 series, offering pin-compatible options while reducing power consumption through 3.3V operation.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements may include other MAX 7000B variants or MAX 7000S devices with matching I/O counts. Verify package dimensions and electrical specifications before substitution.
