Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'XC' against official Infineon documentation to confirm package type and temperature range, as standard datasheets may list generic variants. Confirm availability status as this component belongs to the legacy Ultra37000 family which may have limited new production.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 64 macrocells with a 125 MHz speed grade. Ensure the 44-lead TQFP package fits the board layout. Verify VCCO requirements if interfacing with 3.3V buses, as the 5V version requires specific voltage configurations for compatibility.

Complex Programmable Logic Devices Part Context

This part belongs to the Ultra37000 family of CMOS CPLDs originally developed by Cypress Semiconductor and later acquired by Infineon Technologies. The family is characterized by its simple timing model and high routability through the Programmable Interconnect Matrix (PIM).

Complex Programmable Logic Devices Replacement Considerations

Check for updated revisions within the CY37064 series. Cross-reference with other 64-macrocell CPLDs from current Infineon portfolios if ISR functionality is not strictly required.
