Complex Programmable Logic Devices Procurement Notes

Verify the manufacturer origin as Cypress Semiconductor or Infineon Technologies due to corporate acquisition history. Confirm the 'A' suffix indicates lead-free composition and the 'XI' suffix denotes industrial temperature grade (-40°C to +85°C). Ensure compatibility with 5V ISR programming requirements.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 64 macrocells with a 154 MHz speed bin. The 44-lead TQFP package provides 37 usable I/Os. Verify that the design utilizes the 5V supply architecture, as 3.3V versions belong to the CY37064V series. Ensure the application leverages the simple timing model without fanout penalties.

Complex Programmable Logic Devices Part Context

This component belongs to the Ultra37000 family of CMOS CPLDs. The family offers high-density programmable logic solutions ranging from 32 to 512 macrocells. The CY37064 variant sits in the lower density tier, providing a balance of performance and pin count for moderate complexity logic applications.

Complex Programmable Logic Devices Replacement Considerations

Check for CY37064P44-154ACXIT or CY37064P44-154JXIT for commercial or other industrial variants within the same package. Cross-reference with CY37064V series if 3.3V operation is required, noting the different electrical characteristics.
