XCR3128XL-6CSG144C

Overview

The XCR3128XL-6CSG144C is a Complex Programmable Logic Device (CPLD) belonging to the CoolRunner-XPLA3 family, manufactured by AMD. It features an EEPROM-based non-volatile memory architecture with 128 macrocells and 3000 usable gates organized into two logic array blocks. The device supports up to 108 I/Os and operates within a supply voltage range of 2.7V to 3.6V. It is housed in a 144-pin CSBGA package and offers a maximum operating frequency of 175 MHz with a typical propagation delay of 6 ns.

Feature Summary

• EEPROM-based technology enabling system-in-programmability and over 1,000 erase/rewrite cycles.
• High-speed performance with a maximum frequency of 175 MHz and 6 ns propagation delay.
• Flexible I/O configuration supporting up to 108 user-accessible pins.
• JTAG boundary scan support for manufacturing test and debugging.

Applications

• System control and interface logic in embedded systems.
• Address decoding and bus bridging in industrial equipment.
• State machine implementation for automated testing hardware.
• Replacement for legacy GALs or PALs in existing designs.

Procurement Notes

Verify component authenticity through authorized distributors due to potential availability from multiple manufacturers including AMD and Xilinx. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for surface-mount assembly processes. Check for end-of-life notifications as this series may have discontinuation notices.

Selection Notes

Select this model when 128 macrocells are sufficient for the design complexity. Ensure the CSBGA-144 package fits the PCB footprint constraints. Verify that the 2.7V to 3.6V VCCIO/VCCINT supply rails match the system power budget. Consider the -6 speed grade if 6 ns delay meets timing requirements; faster grades like -7 or -10 offer lower delays but may cost more.

Part Context

This part is part of the CoolRunner-XPLA3 CPLD family, which bridges the gap between simple PLDs and high-density FPGAs. It was originally developed by Xilinx and later integrated into AMD's portfolio following the acquisition. The family is known for low power consumption and ease of use compared to SRAM-based FPGAs.

Replacement Considerations

Direct pin-to-pin replacements may include other speed grades within the same package such as XCR3128XL-7CSG144C or XCR3128XL-10CSG144C, provided timing constraints allow. Cross-vendor equivalents like Lattice LC4128V series should be evaluated for functional compatibility and pinout alignment.
