Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized AMD distributors due to potential availability constraints. Confirm RoHS compliance status and check for Product Change Notifications (PCNs) regarding manufacturing site transfers or material updates. Ensure design-in documentation matches the specific -7 speed grade and PQG208 package variant.

Complex Programmable Logic Devices Selection Notes

Select this model when 256 macrocells are sufficient for the design complexity. The -7 speed grade provides 7.1 ns delay, suitable for moderate frequency applications. The PQG208 package offers 208 I/O pins, requiring verification against PCB footprint constraints. Compare against XC2C128 if fewer resources are needed, or XC2C384 if higher capacity is required.

Complex Programmable Logic Devices Part Context

This part belongs to the AMD CoolRunner-II CPLD family, which utilizes CMOS technology for low-power programmable logic. The CoolRunner-II series is designed for cost-sensitive applications requiring non-volatile configuration and high reliability. It serves as a bridge between microprocessors and peripheral devices in mixed-signal systems.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements within the same family include XC2C128 variants for lower density or XC2C384 variants for higher density, provided resource requirements align. Verify that any substitute maintains the same -7 speed grade and PQG208 package dimensions to ensure mechanical compatibility.
