XCR3256XL-10CSG280I

Overview

The XCR3256XL-10CSG280I is a Complex Programmable Logic Device (CPLD) manufactured by AMD (formerly Xilinx). It features 256 macrocells and operates with a maximum system clock frequency of 105 MHz. The device supports in-system programmability and includes JTAG boundary scan capabilities for testing and configuration. It is housed in a 280-pin FineLine BGA package, measuring 17 mm in length. The component is lead-free and RoHS compliant, designed for applications requiring reliable logic control with moderate I/O density.

Feature Summary

• 256 Macrocells with 9 ns propagation delay
• Maximum operating frequency of 105 MHz
• In-system programmability support
• JTAG boundary scan capability

Applications

• General-purpose logic control
• Address decoding
• Interface bridging

Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range specifications. Confirm the 280-pin FBGA package dimensions match design constraints. Ensure compatibility with existing programming tools for CPLD configuration. Check for end-of-life status or alternative sourcing requirements from authorized distributors.

Selection Notes

Select this model when 256 macrocells are sufficient for the logic design. The 105 MHz speed grade suits moderate-speed synchronous designs. Consider the 280-pin package size for PCB layout feasibility. Compare against lower-density XL series parts if fewer macrocells meet the functional requirements.

Part Context

This part belongs to the XCR3000XL CPLD family. It shares architectural similarities with other members like the XCR3256XL-10FTG256I but differs in package type and pin count. The family provides non-volatile configuration storage and high-density logic integration for embedded systems.

Replacement Considerations

Direct substitutes include other XCR3256XL variants with compatible packages, such as XCR3256XL-10FTG256I, though pinout differences require schematic review. Verify electrical characteristics and package dimensions before swapping.
