Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range (-40°C to +85°C). Confirm the 'VQ44' package designation corresponds to the 44-pin VQFP plastic package. Ensure compatibility with existing programming tools such as Xilinx Platform Cable or compatible JTAG adapters for configuration.

Complex Programmable Logic Devices Selection Notes

Select this component when a small number of macrocells are sufficient for glue logic replacement. Compare against higher-density CoolRunner-II devices if additional I/O count or logic resources are required. Consider the -7 speed grade only if timing constraints exceed 180 MHz operation requirements.

Complex Programmable Logic Devices Part Context

This part belongs to the CoolRunner-II CPLD family, which succeeded the CoolRunner-I series with improved performance and lower power consumption. It serves as a drop-in replacement for many discrete logic gate designs, reducing board space and assembly costs while maintaining reliable operation in industrial environments.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package may include other CoolRunner-II parts with equal or greater macrocell counts, such as XC2C32A or XC2C64A variants with different speed grades. Verify that any substitute maintains the same VCCIO supply voltage requirements.
