Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence. Confirm package integrity and pin alignment prior to PCB assembly. Ensure programming equipment supports the specific ISP algorithm requirements for MAX 7000S devices.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells and high-speed 6 ns performance are required in a TQFP-100 package. Consider the -7 speed grade for applications needing 147.1 MHz operation. Verify that the design environment supports the MAX 7000 family architecture and JTAG programming protocols.

Complex Programmable Logic Devices Part Context

This component belongs to the Altera MAX 7000S family, which extends the standard MAX 7000E features with in-system programmability and JTAG boundary-scan capabilities. It serves as a high-density PLD solution for designs requiring reconfigurable logic with robust testing and programming flexibility.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same density and package are limited due to the specific S suffix and speed grade. Evaluate MAX 7000S variants with matching I/O counts and timing specifications, ensuring ISP compatibility.
