XCR3064XL-7PC44I

Overview

The XCR3064XL-7PC44I is a Complex Programmable Logic Device (CPLD) belonging to the Xilinx XPLA3 family. It features 64 macrocells and supports up to 36 I/O pins within a PLCC-44 package. The device operates on a supply voltage ranging from 3 V to 3.6 V and utilizes EEPROM storage technology for non-volatile configuration. Key electrical specifications include a maximum propagation delay of 5.5 ns, a maximum operating frequency of 192 MHz, and a typical operating current of 30 mA. It is designed for surface-mount installation with an industrial temperature range spanning from 0°C to +70°C.

Feature Summary

• XPLA3 architecture with 64 macrocells and 1500 system gates
• EEPROM-based non-volatile memory for instant-on functionality
• High-speed performance with 5.5 ns max propagation delay
• 36 I/O lines available in a 44-pin PLCC package

Applications

• General-purpose digital logic replacement
• Address decoding and bus interfacing
• State machine implementation
• Parallel-to-serial conversion

Procurement Notes

Verify the specific suffix 'I' against official AMD/Xilinx documentation to confirm the extended industrial temperature rating (-40°C to +85°C) versus the commercial 'C' variant. Ensure compatibility with existing PCB footprints for the PLCC-44 package. Confirm end-of-life status or lifecycle recommendations through authorized distributors prior to final design approval.

Selection Notes

Select this component when a moderate density CPLD with non-volatile configuration is required. The XPLA3 series offers a balance of speed and pin count suitable for legacy interface bridging. Compare the 5.5 ns delay against timing requirements of the target system. Consider the 3.3V I/O levels for direct connection to standard logic families without additional level shifting.

Part Context

This part is part of the XCR3000XL family, which succeeded the original XCR3000 series. The XPLA3 generation introduced improved speed grades and lower power consumption while maintaining backward compatibility with previous design tools. AMD acquired Xilinx, making this part part of the broader AMD programmable solutions portfolio.

Replacement Considerations

Direct pin-compatible replacements may include other XPLA3 devices with different speed grades, such as the XCR3064XL-7PC44C for commercial temperature ranges. Verify that any substitute maintains the same 64 macrocell count and I/O distribution.
