Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C) compared to commercial variants. Confirm package integrity for the VQFP-44 form factor. Check current availability status as legacy CPLDs may have limited stock or end-of-life implications. Ensure voltage levels match the 3.3V requirement.

Complex Programmable Logic Devices Selection Notes

Select this model when 36 macrocells are sufficient for the design logic. Compare against XC9536-10VQ44 for faster switching speeds if timing constraints allow. Verify that the 3.3V I/O levels are compatible with the target system interfaces. Consider the VQFP-44 footprint for PCB layout constraints.

Complex Programmable Logic Devices Part Context

This component belongs to the Xilinx 9500XL series, an evolution of the original 9500 line offering lower power consumption and higher density. It serves as a drop-in replacement for older E²CMOS devices in many applications while providing improved performance and reliability through Flash technology.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible alternatives within the same family include XC9536-10VQ44 for higher speed requirements. Cross-family replacements require careful verification of pinout and logic capacity.
