XCR3064XL-10VQ44C

Overview

The XCR3064XL-10VQ44C 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/O pins within a VQFP-44 surface-mount package. The device operates on a supply voltage ranging from 3.0 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 functions within an industrial temperature range of 0°C to +70°C.

Feature Summary

• Contains 64 macrocells organized into 2 Logic Array Blocks (LABs) with 1500 system gates.
• Supports high-speed operation with a maximum frequency of 192 MHz and 5.5 ns propagation delay.
• Utilizes EEPROM technology for instant-on functionality without external configuration memory.
• Available in a 44-pin VQFP (Very Thin Quad Flat Package) suitable for SMD/SMT mounting.

Applications

• General-purpose logic replacement in embedded systems
• Address decoding and bus bridging in industrial control equipment
• Power-on reset generation and supervisor circuits
• Simple state machine implementation in consumer electronics

Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Availability is limited to surplus or secondary market channels. Verify RoHS compliance status carefully, as older production runs may differ from current environmental standards. Check humidity sensitivity levels if the component has been stored for extended periods, as it requires proper handling during reflow soldering.

Selection Notes

Select this part when a low-cost, low-pin-count CPLD with instant-on capability is required. The 64 macrocell count is suitable for simple glue logic applications rather than complex data processing. Ensure the design accommodates the 3.0 V to 3.6 V power supply range. Consider the VQFP-44 package dimensions for PCB layout constraints compared to smaller QFN options if space is critical.

Part Context

The XCR3064XL belongs to the XC3000XL family, which was designed to offer improved performance and density over the original XC3000 series while maintaining pin compatibility. This specific model represents a mid-range option in the XL series, balancing gate count with speed. It serves as a bridge between simple discrete logic and more complex FPGAs, offering deterministic timing characteristics essential for legacy system upgrades.

Replacement Considerations

Direct pin-to-pin replacements are limited due to the obsolete status. Potential alternatives include other CPLDs from the same family with different speed grades or package types, such as the XCR3064XL-10VQG44C (different package). Cross-reference with newer low-power CPLD families from AMD/Xilinx or competitors like Lattice, ensuring voltage levels and I/O drive strengths match the existing design requirements.
