XCR3064XL-10VQG44C

Overview

The XCR3064XL-10VQG44C is a Complex Programmable Logic Device (CPLD) from the XCR3064XL series, manufactured by AMD/Xilinx. It features 64 macrocells and supports up to 36 I/Os within a VQFP-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 operating frequency of 192 MHz, a typical propagation delay of 5.5 ns, and a maximum operating current of 30 mA. It is designed for surface-mount installation and functions within an ambient temperature range of 0°C to +70°C.

Feature Summary

• Contains 64 macrocells and 1500 system gates organized into 2 Logic Array Blocks (LABs).
• Supports high-speed operation with a maximum frequency of 192 MHz and 5.5 ns propagation delay.
• Utilizes EEPROM technology for instant-on capability and non-volatile data retention.
• Available in a 44-pin Very Thin Quad Flat Package (VQFP) for surface-mount applications.

Applications

• General-purpose digital logic replacement in industrial control systems.
• Address decoding and bus buffering in embedded computer architectures.
• State machine implementation for consumer electronics.
• Interface translation between different voltage domains or protocols.

Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Verification of availability requires checking secondary market distributors for surplus stock. Buyers should confirm the specific revision level and ensure compatibility with existing PCB footprints before procurement. RoHS compliance details are available in the official datasheet but require direct verification due to the product's lifecycle status.

Selection Notes

Select this part when a low pin count CPLD with non-volatile configuration is required. The 64 macrocell capacity suits simple logic functions, whereas larger designs may require the XCR3096XL or XCR3128XL variants. Ensure the design accommodates the 3.0 V to 3.6 V power supply range and the thermal characteristics of the VQFP-44 package. Verify that the 192 MHz speed grade meets the timing requirements of the target application.

Part Context

The XCR3064XL belongs to the XL family of CPLDs, which succeeded the original XC3000 series. This generation introduced improved performance metrics and lower power consumption while maintaining compatibility with legacy design tools. The '10' suffix indicates the 10 ns speed grade, and 'VQG44' specifies the VQFP-44 package variant. This series was widely used for bridging legacy logic designs to modern surface-mount manufacturing processes.

Replacement Considerations

As the part is obsolete, direct replacements are limited. Potential alternatives include other CPLDs from the same family with higher macrocell counts if resources allow, or modern FPGA/CPLD equivalents from AMD/Xilinx such as the CoolRunner-II or CoolRunner-ZU series. Cross-reference pinouts and voltage levels carefully when substituting with devices from other manufacturers.
