Complex Programmable Logic Devices Procurement Notes

Verify component authenticity as this part number may be subject to obsolescence or limited availability from original manufacturers. Confirm RoHS compliance status and specific speed grade suffixes against current distributor listings, as supply chain conditions for legacy CPLDs can vary significantly.

Complex Programmable Logic Devices Selection Notes

Select the EPM7064SLC44-7 when 64 macrocells and 36 I/Os are required in a compact 44-pin PLCC form factor. Ensure design requirements align with 5.0-V operation and that ISP functionality via JTAG is supported by the target programming hardware. Consider thermal management for dense PCB layouts.

Complex Programmable Logic Devices Part Context

This component is part of the MAX 7000S series, which enhances the standard MAX 7000 architecture with ISP capabilities. It shares architectural similarities with the EPM7064SLC44-10 but offers faster switching speeds. The device utilizes CMOS EEPROM technology for logic implementation within the second-generation MAX architecture.

Complex Programmable Logic Devices Replacement Considerations

Direct functional substitutes within the same package and speed grade are limited due to the age of the product line. Designers may consider upgrading to newer Intel/Altera CPLD families such as MAX 10 or Agilex, though these require significant schematic and software migration efforts.
