XCR3128XL-10VQG100C

Overview

The AMD XCR3128XL-10VQG100C is a Complex Programmable Logic Device (CPLD) belonging to the XCR3000XL family. It features 128 macrocells and supports up to 84 I/O pins within a 100-pin VQFP package. The device operates on a supply voltage range of 2.7 V to 3.6 V and guarantees a maximum operating frequency of 175 MHz with a typical propagation delay of 5.5 ns. Designed for surface-mount installation, it functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• 128 Macrocells with System-In-Programmable (SIP) capability
• Maximum operating frequency of 175 MHz
• 100-pin VQFP (14x14 mm) surface-mount package
• Industrial temperature range: -40°C to +85°C

Applications

• High-speed interface bridging
• Address decoding and control logic
• State machine implementation in embedded systems

Procurement Notes

This component is designated as End-of-Life (EOL) by the manufacturer. Availability is restricted to existing stock or third-party distributors. Verify the manufacturing date code and authenticity carefully, as original production has ceased. Ensure compliance with RoHS standards if required by the specific application environment.

Selection Notes

Select this model when 128 macrocells are sufficient for the design logic requirements. The 10ns speed grade (-10 suffix) offers a balance between performance and power consumption. Consider the VQFP100 package constraints regarding PCB real estate and thermal dissipation. Verify that the 2.7V–3.6V I/O voltage levels match the target system interfaces.

Part Context

The XCR3128XL is part of the Xilinx/XCR3000XL CPLD family, which succeeded earlier XCR3000 series devices. These devices utilize CMOS technology and offer non-volatile configuration storage. The XCR3128XL specifically provides a moderate density solution suitable for replacing discrete logic gates or smaller PLDs in legacy and modern embedded designs.

Replacement Considerations

Direct pin-to-pin replacements may be limited due to the EOL status. Potential alternatives include other members of the XCR3000XL family with different package options or higher macrocell counts, such as the XCR3256XL series, provided the pinout compatibility is verified through official datasheets.
