XCR3128XL-10CS144C

Overview

The XCR3128XL-10CS144C is a Complex Programmable Logic Device (CPLD) from the XCR3000XL family, manufactured by AMD. It features 128 macrocells and supports up to 108 I/Os within a 144-pin CSBGA package. The device utilizes EEPROM technology for non-volatile configuration storage and operates on a single 3.3V supply voltage. Key electrical specifications include a maximum operating frequency of 95 MHz and a typical propagation delay of 10 ns. It supports system-in-system programming and JTAG boundary scan testing.

Feature Summary

• 128 Macrocells with 3000 usable gates
• EEPROM-based non-volatile memory architecture
• Supports System-In-System Programming (SISP)
• JTAG boundary scan compliance

Applications

• Address decoding and bus bridging
• Logic replacement for discrete components
• Interface translation between different voltage domains

Procurement Notes

Verify the specific suffix 'C' against official AMD documentation to confirm temperature grade and package variant, as generic listings may not distinguish between commercial and industrial grades accurately. Confirm availability status as older CPLD families may have limited production runs or obsolescence notices.

Selection Notes

Select this component when a small number of logic resources is required with non-vatile configuration retention. Compare against the XCR3128XL-10TQG144I if a TQFP package is preferred over CSBGA. Ensure the design requires only 3.3V operation, as this device does not support lower voltage cores natively without external level shifting.

Part Context

This part belongs to the Xilinx CoolRunner-XL (XCR3000XL) family, which was designed for low-power, high-density applications. The family succeeded the original CoolRunner series, offering improved performance and density while maintaining compatibility with existing design tools. AMD acquired Xilinx in 2022, but the product lineage remains distinct from modern FPGA architectures.

Replacement Considerations

Direct pin-to-pin replacements are limited due to the end-of-life status of many CPLD families. Check for XCR3128XL variants with different packages (e.g., TQFP, PQFP) if the footprint allows. No direct functional equivalents exist in current AMD portfolios; modern designs typically migrate to Lattice MachXO or Gowin GW1N series.
