XCR3128XL-7CSG144C

Overview

The XCR3128XL-7CSG144C is a Complex Programmable Logic Device (CPLD) belonging to the CoolRunner-XPLA3 family, manufactured by AMD. It features 128 macrocells and supports up to 108 I/O pins within a 144-pin CSBGA package. The device operates on an EEPROM storage technology, allowing for system-in-system programmability with over 1,000 programming/erase cycles. Electrical specifications include a maximum operating frequency of 175 MHz and a typical propagation delay of 5.5 ns. It functions within a supply voltage range of 2.7 V to 3.6 V and is rated for industrial temperature operations from -40°C to +85°C.

Feature Summary

• 128 Macrocells with 3000 usable gates and 2 Logic Array Blocks (LABs)
• Supports System-In-System Programming (SISP) via onboard EEPROM
• High-speed performance with 175 MHz max frequency and 5.5 ns propagation delay
• Industrial temperature range (-40°C to +85°C) with 2.7V to 3.6V operation

Applications

• High-density logic replacement in industrial control systems
• Bus bridging and protocol conversion in embedded networks
• Address decoding and memory interface management
• State machine implementation for automated machinery

Procurement Notes

This component is designated as End-of-Life (EOL) by the manufacturer. Availability is restricted to existing stock or third-party distributors. Verification of authenticity and lot traceability is critical due to the discontinuation status. Buyers should confirm moisture sensitivity level (MSL 3) handling requirements before assembly to prevent package damage during reflow soldering.

Selection Notes

Select this part when a robust, non-volatile CPLD solution is required for designs needing frequent field updates via SISP. The 144-pin CSBGA package suits high-density PCB layouts. Ensure the design utilizes the 2.7V-3.6V VCC range. For pin-compatible alternatives with different packages, consider the TQFP or VQFP variants within the same XCR3128XL series, noting that I/O counts may vary by package type.

Part Context

The XCR3128XL-7CSG144C is part of the CoolRunner-XPLA3 series, which succeeded earlier XPLA3 devices with enhanced speed and lower power consumption. This specific suffix 'CSG144' denotes the Commercial/Industrial grade (implied by context of similar parts, though datasheet specifies industrial temp) 144-ball Chip Scale Ball Grid Array package. It serves as a bridge between simple GALs and larger FPGAs, offering deterministic timing and ease of use for medium-complexity logic applications.

Replacement Considerations

Direct pin-to-pin replacements are limited due to EOL status. Potential functional equivalents include Lattice Semiconductor's LC4128V series or AMD/Xilinx's own XC9500/XC9500XL series, though package and pinout differences require schematic review. Verify logic density and I/O voltage compatibility before substituting.
