XCR3128XL-10TQ144C

Overview

The XCR3128XL-10TQ144C is a Complex Programmable Logic Device (CPLD) from the XCR3128XL family, manufactured by AMD/Xilinx. It features 128 macrocells and 3000 usable gates, housed in a 144-pin TQFP package. The device supports system-in-programmability via EEPROM technology and operates within a voltage range of 3 V to 3.6 V. Key electrical specifications include a maximum operating frequency of 175 MHz and a typical propagation delay of 5.5 ns. It provides 108 I/O pins and includes JTAG boundary scan support for testing.

Procurement Notes

This component is listed as an End-of-Life (EOL) product. Verification of current availability requires checking authorized distributors or secondary market suppliers. Ensure that any sourced units are verified for authenticity and proper storage conditions due to the moisture sensitivity level indicated in the datasheet.

Selection Notes

Select this part when a low-density CPLD with high-speed performance (up to 175 MHz) is required. The 144-pin TQFP package offers 108 I/Os suitable for moderate pin-count applications. Consider the 3V to 3.6V supply requirement and ensure compatibility with the target system's power rails and interface standards.

Part Context

The XCR3128XL series represents an enhanced version of the XC3000XL family, offering improved speed and density. The '10' suffix indicates the -10 speed grade, while 'TQ144' specifies the Thin Quad Flat Package with 144 pins. The 'C' suffix typically denotes the commercial temperature range (0°C to +70°C).

Replacement Considerations

As an EOL product, direct replacements may be limited. Verify functional equivalence with other XCR3000XL variants or newer AMD/Xilinx CPLD families such as the XC9500XL or CoolRunner-II series, ensuring pinout and I/O count compatibility.
