XCR3064XL-10PC44I

Overview

The XCR3064XL-10PC44I is a Complex Programmable Logic Device (CPLD) belonging to the Xilinx XPLA3 family, manufactured by AMD. It features an EEPROM-based non-volatile configuration memory and operates within a supply voltage range of 2.7 V to 3.6 V. The device provides 64 macrocells, 36 I/O lines, and approximately 1500 usable gates organized into two logic array blocks. It is housed in a 44-pin PLCC package with surface-mount installation. The component supports a maximum operating frequency of 95 MHz and exhibits a typical propagation delay of 10 ns, suitable for general-purpose digital logic applications.

Feature Summary

• XPLA3 architecture with 64 macrocells and 36 I/Os
• EEPROM storage technology for non-volatile configuration
• 95 MHz maximum operating frequency with 10 ns propagation delay
• Single 3.3 V power supply operation

Applications

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

Procurement Notes

Verify the specific suffix 'I' against official AMD/Xilinx documentation to confirm industrial temperature rating specifications (-40°C to +85°C). Ensure compatibility with existing PCB footprints for the PLCC-44 package. Confirm that the design toolchain supports the legacy XPLA3 series for programming and verification.

Selection Notes

Select this component when a moderate density CPLD with EEPROM retention is required. Compare against the -7 speed grade variant if higher performance is needed, or the -10 variant if cost optimization is prioritized over the slight timing margin difference. Ensure the application environment remains within the specified industrial temperature range for the 'I' suffix version.

Part Context

This part belongs to the XPLA3 family, which succeeded earlier XPLA devices with improved performance and lower power consumption. The XCR3064XL designation indicates the XL (low power) variant with 3064 system gates. The PC44 suffix denotes the plastic quad flat pack package with 44 leads, a standard form factor for through-hole or surface-mount integration in compact designs.

Replacement Considerations

Direct pin-compatible replacements include other XPLA3 variants such as XCR3064XL-7PC44I or XCR3064XL-10PC44C, provided temperature ranges match. Cross-family upgrades may require schematic modifications due to architectural differences.
