XCR3064XL-6CPG56C

Overview

The XCR3064XL-6CPG56C is a Complex Programmable Logic Device (CPLD) from the Xilinx XC3000 family, manufactured by AMD. It features 64 macrocells and operates at a maximum system clock frequency of 166 MHz with a 6 ns propagation delay. The device utilizes a 0.5 µm CMOS technology and supports up to 28 I/O pins within a 56-pin CQFP package. It includes 2,048 bits of user programmable non-volatile Flash memory for configuration storage.

Feature Summary

• 64 Macrocells with 28 I/Os in a 56-pin CQFP package
• Non-volatile Flash configuration memory (2,048 bits)
• System clock frequency up to 166 MHz
• Propagation delay of 6 ns

Applications

• High-density logic replacement
• Address decoding and bus buffering
• State machine implementation
• Interface bridging between different logic families

Procurement Notes

Verify the specific suffix '6' indicates the -6 speed grade (6 ns delay). Confirm the 'X' prefix denotes commercial temperature range. Ensure the 'XL' variant matches the required Flash-based configuration needs versus volatile SRAM-based alternatives in the same family.

Selection Notes

Select this component when non-volatile configuration is required without external PROMs. Compare against the standard XC3064 if higher speed or different packaging is needed. Verify pin compatibility with existing PCB layouts due to the specific CQFP footprint and I/O count constraints.

Part Context

This part belongs to the AMD/Xilinx XC3000 series, a generation of CPLDs known for introducing Flash-based configuration. It serves as a bridge between simple gate arrays and more complex FPGAs, offering deterministic timing and instant-on capability due to its non-volatile memory architecture.

Replacement Considerations

Direct replacements include other XC3000 series devices like the XC3064V-6CPG56I for industrial temperature ranges. Cross-family migration may require FPGA solutions such as the Lattice MACH XO series or AMD Spartan-7 for increased logic density.
