XC9572XL-7CS48I

Overview

The AMD XC9572XL-7CS48I is a Complex Programmable Logic Device (CPLD) belonging to the XC9500XL family. It features 72 macrocells and supports System In-Programmability with a minimum of 10,000 program/erase cycles. The device operates within a supply voltage range of 3V to 3.6V and offers a maximum propagation delay of 7.5 ns. It is housed in a 48-pin CSOP package and is rated for an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Supports System In-Programmability allowing field updates without removal from the circuit board.
• Utilizes non-volatile Flash technology to retain configuration data when power is removed.
• Features high-density logic blocks suitable for complex digital design implementations.

Applications

• Address decoding and bus bridging in embedded systems
• Translation between different logic families or voltage levels
• State machine implementation in industrial control units

Procurement Notes

Verify component authenticity through authorized distributors as this part may be obsolete. Confirm specific suffix codes match exact package and temperature requirements. Request original manufacturer documentation to validate electrical characteristics against current design specifications before integration into production hardware.

Selection Notes

Select this component when non-volatile programmability and moderate logic density are required. Ensure the design accommodates the 3V to 3.6V supply voltage constraints. Verify that the 7.5 ns speed grade meets the timing requirements of the target application interface.

Part Context

This CPLD is part of the XC9500XL series, which succeeded the original XC9500 line. The XL series introduced lower power consumption and higher density capabilities while maintaining compatibility with existing development tools. It serves as a drop-in replacement for legacy GAL devices in many applications.

Replacement Considerations

Consult official cross-reference guides for direct pin-compatible alternatives. Verify that substitute components maintain identical voltage ranges and programming interfaces to ensure functional equivalence in existing designs.
