XC9572-15TQ100I

Complex Programmable Logic Devices Overview

The XC9572-15TQ100I is an in-system programmable Complex Programmable Logic Device (CPLD) from the Xilinx XC9500XL family. It features 7,360 system gates and supports up to 84 user I/O pins in a 100-pin TQFP package. The device operates with a single 5V supply voltage and includes non-volatile Flash memory for configuration retention. Key electrical characteristics include a maximum propagation delay of 15 ns and support for JTAG-based programming and debugging interfaces.

Complex Programmable Logic Devices Feature Summary

• Address decoding and bus bridging
• State machine implementation in industrial control systems
• Simple processor interface logic

Complex Programmable Logic Devices Procurement Notes

Verify the manufacturer origin, as AMD acquired Xilinx. Confirm the specific suffix '15TQ100I' matches the required speed grade (-15), package (TQFP-100), and industrial temperature range ('I'). Ensure documentation references the original Xilinx datasheet for accurate electrical specifications.

Complex Programmable Logic Devices Selection Notes

Select this component when a non-volatile CPLD with moderate I/O count and 5V compatibility is required. Compare against the standard XC9572 if higher speed grades or different packaging options are needed. Verify that the target application does not require lower voltage operation, as this device is designed for 5V logic levels.

Complex Programmable Logic Devices Part Context

The XC9572 belongs to the XC9500XL series, which succeeded the original XC9500 family. This series introduced Flash memory technology, eliminating the need for external EPROM programmers and enabling in-system programming. It remains a common choice for cost-sensitive designs requiring persistent logic configuration without volatile SRAM-based FPGA reconfiguration overhead.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may include other XC9500XL variants with compatible packages and speed grades. Cross-reference with XC9572-15TQ100 or XC9572-10TQ100I if timing requirements allow. Verify that any substitute maintains the same I/O count and power supply requirements.
