XC9572-10PQ100I

Overview

The XC9572-10PQ100I is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family, housed in a 100-pin PQFP package. It features 72 macrocells, 1600 usable gates, and four Logic Array Blocks (LABs). The device operates at a maximum frequency of 125 MHz with a typical propagation delay of 10 ns. It supports in-system programming via JTAG and functions within a supply voltage range of 2.37 V to 2.62 V. The industrial temperature grade ensures reliable operation between -40°C and +85°C.

Feature Summary

• In-System Programmability: Supports non-volatile configuration via JTAG interface for flexible design updates.
• High Performance: Delivers 125 MHz operating speed with 10 ns propagation delay for high-speed logic applications.
• Scalable Architecture: Contains 72 macrocells distributed across 4 LABs, providing 1600 system gates.
• Industrial Reliability: Rated for extended temperature ranges (-40°C to +85°C) suitable for demanding environments.

Applications

• Address decoding and bus bridging in embedded systems
• Translation between different voltage domains or logic families
• State machine implementation for motor control and instrumentation
• Replacement for legacy GALs and PALs in existing hardware designs

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature rating (-40°C to +85°C), distinct from commercial variants. Confirm the 'PQ100' designation matches the 100-pin Thin Quad Flat Package. Ensure sourcing channels provide authenticity guarantees due to the component's age and potential availability of refurbished units.

Selection Notes

Select this model when 72 macrocells are sufficient for the logic density requirements. Compare against the XC9572XL series if lower power consumption is critical, as the XL variant offers optimized architecture. Verify that the 10 ns delay meets the timing constraints of the target clock domain.

Part Context

This component belongs to the XC9500XL CPLD family, representing an evolution of the original XC9500 series with improved performance and lower power characteristics. Manufactured by AMD (formerly Xilinx), it serves as a bridge between simple discrete logic and complex FPGAs, offering non-volatility without the complexity of FPGA configuration memories.

Replacement Considerations

Direct pin-compatible replacements include other packages within the XC9572 family, such as the TQFP version (XC9572-10TQ100I). For functional equivalents with potentially lower power, consider the XC9572XL-10PQ100I, provided the toolchain supports the XL architecture.
