XCR3032XL-7VQ44I

Overview

The XCR3032XL-7VQ44I is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XCR3000XL family. It features 32 macrocells, 750 usable gates, and 36 I/O pins in a VQFP-44 package. The device operates on a single 3.3V supply with a maximum propagation delay of 7ns and a maximum frequency of 143MHz. It utilizes non-volatile EEPROM technology for configuration retention.

Feature Summary

• Non-volatile EEPROM architecture ensures configuration data retention without external memory.
• High-density logic resources within a compact VQFP-44 surface-mount package.
• Supports in-system programmability via standard JTAG interfaces.

Applications

• Address decoding and bus bridging in embedded systems
• Simple state machine implementation for industrial control
• Level shifting and protocol conversion between logic families

Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range compliance (-40°C to +85°C). Confirm the manufacturer source, as AMD/Xilinx CPLDs are legacy products subject to discontinuation. Ensure EOL status does not impact long-term production viability.

Selection Notes

Select this component when non-volatile configuration is required without external flash. Compare against the XCR3032A series for speed differences; the XL variant offers lower power consumption. Verify voltage compatibility with the target system's 3.3V logic levels.

Part Context

Part of the XCR3000XL family, designed for low-power applications. It succeeds the XCR3000A series with improved performance-per-watt metrics while maintaining pin-compatible options across certain packages.

Replacement Considerations

XCR3032A-7VQ44I: Similar functionality but higher power consumption. XCR3032XL-10VQ44I: Faster switching speed (10ns vs 7ns) with identical pinout and logic resources.
