XC9536-10PCG44C

Complex Programmable Logic Devices Overview

The XC9536-10PCG44C is a Complex Programmable Logic Device (CPLD) from the XC9500XL family, manufactured by AMD/Xilinx. It features 36 macrocells and 800 usable gates within two Logic Array Blocks (LABs). The device operates at a maximum frequency of 100 MHz with a typical pin-to-pin propagation delay of 10 ns. It utilizes a 2.5V core voltage supply and supports in-system programming via JTAG. The component is housed in a 44-pin Plastic Quad Flatpack (PQFP) or similar package variant depending on specific suffix interpretation, though the model indicates a 44-pin form factor.

Complex Programmable Logic Devices Procurement Notes

Verify the exact package type against the manufacturer's datasheet, as suffixes can denote variations in lead frame material or temperature grade. Confirm availability status directly with authorized distributors, as older CPLD models may have limited stock or be subject to last-time-buy notices. Ensure the design environment supports the XC9500XL architecture for proper compilation and programming.

Complex Programmable Logic Devices Selection Notes

Select this component when a moderate density of logic resources is required with low power consumption. The 10 ns speed grade offers a balance between performance and power efficiency compared to faster variants. Ensure the system design accommodates the 2.5V core voltage requirement while maintaining compatibility with 5V I/O levels if necessary, as the XC9500XL series typically supports mixed-voltage operation.

Complex Programmable Logic Devices Part Context

This part belongs to the XC9500XL series, an evolution of the original XC9500 Flash CPLD family. It retains the same architectural structure but introduces improved manufacturing processes for lower power consumption and higher reliability. The series is known for its non-volatile Flash memory technology, allowing unlimited program/erase cycles without the endurance limitations of EEPROM-based devices.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other members of the XC9500XL family such as XC9536-10VQ44C or XC9536-10PC44C, provided the package footprint matches. Cross-family migration to XC9572XL or XC95144XL requires resource expansion verification. Legacy XC9500 parts are functionally compatible but may differ in power specifications.
