XCR3064XL-10VQG44I

Overview

The AMD XCR3064XL-10VQG44I is a Complex Programmable Logic Device (CPLD) from the XCR3000XL family. It features 64 macrocells, 2 logic array blocks (LABs), and 36 I/O pins in a VQFP-44 package. The device operates on a single 3.0V to 3.6V supply with a maximum operating frequency of 192 MHz and a typical propagation delay of 5.5 ns. It utilizes EEPROM technology for non-volatile configuration storage and supports industrial temperature ranges.

Feature Summary

• Contains 64 macrocells organized into 2 LABs with 1500 usable gates.
• Supports up to 36 general-purpose I/O pins.
• Features EEPROM-based non-volatile memory for instant-on configuration.
• Operates within a 3.0V to 3.6V voltage range.

Applications

• General-purpose digital logic replacement
• Address decoding and bus bridging
• Glue logic for microprocessor systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the 'I' suffix indicates industrial temperature rating compliance. Check current lifecycle status as legacy components may have limited availability or require alternative sourcing strategies.

Selection Notes

Select this model when 64 macrocells are sufficient for the design complexity. Ensure the system requires a 3.3V supply rail. Compare against the 'C' variant if commercial temperature range is acceptable. Verify pin compatibility with existing PCB footprints for VQFP-44 packages.

Part Context

This part belongs to the XCR3000XL series, an enhanced version of the original XCR3000 CPLDs. The series offers improved performance and lower power consumption compared to predecessors while maintaining pin-to-pin compatibility with older generations.

Replacement Considerations

Direct substitutes include other XCR3064XL variants with different speed grades or package types. Cross-reference with Xilinx/AMD legacy product transition documents for recommended modern equivalents if discontinuation is confirmed.
