Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'SRC' against official documentation to confirm voltage and package variations. Confirm availability status as older MAX 7000 series components may have limited supply chains or end-of-life statuses. Ensure compatibility with 3.3-V power supplies and JTAG programming interfaces during procurement planning.

Complex Programmable Logic Devices Selection Notes

Select this component for designs requiring 256 macrocells and high-speed performance up to 128.2 MHz. The 208-pin PQFP package suits applications needing extensive I/O connectivity. Consider the 7.5 ns propagation delay for timing-critical paths. Verify that the 3.3-V operating voltage aligns with the target system's power domain requirements.

Complex Programmable Logic Devices Part Context

This part belongs to the MAX 7000S family, which enhances the standard MAX 7000E features with ISP capabilities. It utilizes CMOS EEPROM technology, allowing reprogramming up to 100 times. The device integrates fast input registers and enhanced interconnect resources for improved routability compared to earlier generations.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same speed grade are limited due to the discontinuation of many MAX 7000 variants. Check for MAX 7000S devices with identical macrocell counts and package types. Modern FPGA alternatives may require significant architectural redesign.
