XCR3064XL-6PC44C

Overview

The XCR3064XL-6PC44C is a Complex Programmable Logic Device (CPLD) belonging to the Xilinx XPLA3 family. It features 64 macrocells and supports up to 36 I/O lines 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 parameters include a maximum propagation delay of 6 ns, corresponding to a maximum operating frequency of 192 MHz. The component is designed for surface mount installation and functions within a commercial temperature range of 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 6 ns max propagation delay
• 36 I/O pins available in a PLCC-44 package

Applications

• General-purpose digital logic replacement
• Address decoding and bus bridging
• Clock buffering and distribution
• Interface translation between different voltage domains

Procurement Notes

Verify the manufacturer source carefully, as AMD/Xilinx CPLDs are frequently subject to obsolescence. Confirm the specific speed grade suffix (-6) matches design timing requirements. Check for RoHS compliance status and lead times, as availability may be limited through secondary markets or obsolete stock channels.

Selection Notes

Select this part when an EEPROM-based CPLD is required for low pin count applications needing immediate power-up readiness. Compare against the -7 speed grade if timing margins allow for cost reduction. Ensure the PLCC-44 footprint is compatible with the PCB layout and that the 3V to 3.6V supply rail is stable within the specified tolerance.

Part Context

This component is part of the XPLA3 series, which succeeded earlier GAL and PAL devices. It offers higher density than legacy programmable logic while maintaining simple programming interfaces. The XCR3064XL variant specifically targets cost-sensitive designs requiring moderate logic capacity without the complexity of FPGA development tools.

Replacement Considerations

Direct pin-compatible replacements may include other XPLA3 variants such as the XCR3064XL-7PC44C if timing specifications permit slower speeds. Verify functional equivalence regarding I/O drive strength and voltage levels before substitution.
