XCR3256XL-10TQ144C

Overview

The XCR3256XL-10TQ144C is a Complex Programmable Logic Device (CPLD) from the XCR3256XL series, manufactured by AMD/Xilinx. It features 256 macrocells and 6000 system gates within two logic array blocks. The device supports up to 120 I/Os and operates on a single 3.0V to 3.6V supply. Key electrical parameters include a maximum propagation delay of 7 ns and a maximum operating frequency of 154 MHz. It utilizes non-volatile EEPROM storage for configuration data.

Feature Summary

• Contains 256 macrocells organized into 2 logic array blocks with 6000 system gates.
• Supports up to 120 user-accessible I/O pins in a TQFP-144 package.
• Features fast 7 ns maximum propagation delay and 154 MHz maximum clock frequency.
• Uses non-volatile EEPROM technology for instant-on configuration without external memory.

Applications

• High-density logic replacement in industrial control systems.
• Address decoding and bus bridging in embedded computing platforms.
• State machine implementation for automated manufacturing equipment.
• Interface translation between legacy protocols and modern digital systems.

Procurement Notes

Verify component authenticity through authorized distributors or certified secondary market suppliers. Confirm lot codes and date codes against current inventory records. Ensure proper ESD handling procedures are followed during inspection and storage, as CMOS devices are sensitive to electrostatic discharge. Check for physical damage to leads before integration.

Selection Notes

Select this model when design requirements specify exactly 256 macrocells and high-speed performance under 10 ns delay. Compare against the XCR3256XL-12 variant if lower speed operation at reduced power is acceptable. Ensure the TQFP-144 footprint matches the PCB layout constraints. Verify that the 3.3V I/O levels are compatible with the target system voltage domains.

Part Context

This component belongs to the XCR3000XL family, which succeeded the original XCR3000 line with improved performance and lower power consumption. The 'XL' designation indicates enhanced features such as higher density and faster switching speeds compared to previous generations. This specific part number represents the commercial temperature range version in a 144-pin thin quad flat pack.

Replacement Considerations

Direct pin-to-pin replacements within the same series include the XCR3256XL-12TQ144C, which offers identical functionality with a slower 12 ns speed grade. No other distinct part numbers provide equivalent macrocell counts and I/O configurations in this specific package type.
