XCR3256XL-10CS280I

Overview

The XCR3256XL-10CS280I is a Complex Programmable Logic Device (CPLD) from the XC3000XL family, manufactured by AMD. It features 256 macrocells and supports up to 164 I/O pins. The device operates within a supply voltage range of 2.7 V to 3.6 V. It utilizes CMOS technology and is housed in a CSP-280 package. The component is designed for high-performance logic applications requiring flexible programmability.

Feature Summary

• Supports software-defined and hardware-optimized applications through flexible programmability.
• Utilizes advanced CMOS technology for efficient operation.
• Provides extensive I/O capabilities suitable for complex logic integration.

Applications

• General-purpose digital logic implementation
• Interface bridging between different system components
• State machine control in embedded systems

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required temperature ranges and package variants. Confirm that the CSP-280 package matches the PCB footprint design. Check the lifecycle status as some sources indicate obsolescence. Ensure the voltage specifications align with the target system's power rails before procurement.

Selection Notes

Select this component when a moderate density CPLD with high I/O count is required. The 256 macrocell architecture suits designs needing moderate complexity without the overhead of larger FPGAs. Consider the 10 ns speed grade for timing-critical paths. Evaluate the CSP-280 package constraints against available board space and thermal requirements.

Part Context

This part belongs to the XC3000XL series, which offers enhanced performance over previous generations. It serves as a bridge between simple gate arrays and more complex FPGA solutions. The series is known for its non-volatile configuration memory and robust design tools support within the AMD ecosystem.

Replacement Considerations

Direct substitutes include other parts within the XC3000XL family with compatible pin counts or higher density options such as the XCR3064XL series if additional macrocells are needed. Cross-reference pinouts and electrical characteristics carefully when selecting alternatives.
