XC9572XL-10PC44I

Overview

The AMD XC9572XL-10PC44I is a Complex Programmable Logic Device (CPLD) belonging to the XC9500XL family. It features 72 macrocells, 1600 usable gates, and 34 I/O pins organized into four Logic Array Blocks (LABs). The device utilizes non-volatile Flash memory for configuration, supporting in-system programming with over 10,000 erase/program cycles. It operates within a supply voltage range of 3.0 V to 3.6 V and offers a maximum propagation delay of 10 ns. The component is housed in a 44-pin PLCC package and supports industrial temperature ranges.

Feature Summary

• 72 Macrocells and 1600 Gates across 4 LABs
• Flash-based non-volatile storage with In-System Programming capability
• Maximum propagation delay of 10 ns
• Industrial operating temperature range (-40°C to +85°C)

Applications

• General-purpose digital logic replacement
• Address decoding and bus interfacing
• State machine implementation
• Interface translation between different voltage domains

Procurement Notes

Verify current availability status as the XC9500XL family has reached end-of-life. Confirm RoHS compliance details, as earlier revisions may differ from final production runs. Check for moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Ensure the specific suffix 'I' denotes the industrial temperature grade required for the application environment.

Selection Notes

Select this part when 72 macrocells are sufficient for the design complexity. The 10 ns speed grade is suitable for moderate-frequency applications up to approximately 100 MHz. Compare against the -5 and -7 speed grades if higher performance is needed, or the -15 grade if lower power consumption is prioritized over speed. Ensure the 44-pin PLCC footprint matches the PCB layout constraints.

Part Context

This component is part of the AMD/Xilinx XC9500XL CPLD family, which succeeded the original XC9500 series by integrating Flash technology. This eliminates the need for external configuration PROMs and reduces system cost and board space. The XC9572XL variant provides a balance of density and pin count for mid-range logic applications.

Replacement Considerations

Microchip Technology ATF15xxASV series devices are documented as functional replacements for the XC9500XL family. Verify pin compatibility and logic architecture differences before substitution.
