XC9572XL-10PCG44C

Overview

The XC9572XL-10PCG44C is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family, housed in a 44-pin Plastic Quad Flatpack (PQFP) package. It features 72 macrocells and 1,600 usable gates organized into four Logic Array Blocks (LABs). The device operates at a maximum system frequency of 125 MHz with a typical pin-to-pin propagation delay of 10 ns. It utilizes Fast FLASH technology for non-volatile configuration, supporting in-system programming via JTAG. The component is designed for 3.3V systems with 5V-tolerant I/O pins.

Feature Summary

• 72 Macrocells with 1,600 usable gates across four LABs
• 10 ns maximum pin-to-pin logic delay
• System frequency up to 125 MHz
• Non-volatile Flash memory for instant-on operation

Applications

• High-performance interface bridging between different voltage domains
• State machine implementation in industrial control systems
• Address decoding and bus arbitration in embedded systems

Procurement Notes

Verify the specific suffix 'C' against official AMD datasheets to confirm temperature range and package variant details. As this is an older generation CPLD, check current manufacturing status and lead times directly with authorized distributors or AMD, as availability may be limited compared to newer FPGA families.

Selection Notes

Select this component when non-volatile configuration without external boot memory is required. The 10 ns speed grade offers a balance between performance and power consumption for moderate complexity logic designs. Ensure the design fits within the 72 macrocell limit and verify that the 44-pin PQFP footprint matches the PCB layout constraints.

Part Context

This part belongs to the XC9500XL series, which succeeded the original XC9500 family by offering higher density and lower power consumption while maintaining compatibility. The XC9572XL specifically provides 72 macrocells, making it suitable for applications requiring more logic resources than the smaller XC9536 or XC9518 models but less than the XC95144.

Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the end-of-life status of many CPLDs. Consider the XC9572XL-10VQ44C for a VQFP package if pin count differs, or evaluate modern FPGA alternatives like the Lattice MACH XO2 series for new designs, noting significant architectural differences.
