XCR3128XL-7VQG100C

Overview

The XCR3128XL-7VQG100C is a Complex Programmable Logic Device (CPLD) from the XCR3128XL family, manufactured by AMD. It features 128 macrocells and 84 I/O pins housed in a VQFP-100 surface-mount package. The device operates within a supply voltage range of 3.0 V to 3.6 V and supports a maximum operating frequency of 175 MHz with a typical propagation delay of 5.5 ns. It utilizes EEPROM technology for non-volatile configuration storage and includes two Logic Array Blocks (LABs). The component is rated for commercial temperature operation between 0°C and +70°C.

Feature Summary

• Contains 128 macrocells and 3000 system gates across two Logic Array Blocks.
• Supports up to 84 I/O pins with high-speed performance reaching 175 MHz.
• Utilizes EEPROM-based non-volatile memory for instant-on configuration.
• Operates on a single 3.0 V to 3.6 V power supply.

Applications

• General-purpose digital logic replacement
• Address decoding and bus bridging
• Interface translation between different voltage domains

Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require checking secondary market distributors. Verify the specific revision and authenticity when purchasing from third-party suppliers, as original production has ceased.

Selection Notes

Select this part for designs requiring moderate logic density with immediate power-up functionality due to its EEPROM architecture. Ensure the PCB layout accommodates the VQFP-100 package dimensions. Consider the 175 MHz speed limit for timing-critical paths and verify that the 3.3 V nominal supply aligns with the target system's power rails.

Part Context

The XCR3128XL-7VQG100C belongs to the Xilinx CoolRunner-II XL series, which succeeded the standard CoolRunner-II line. This family offers enhanced performance and lower power consumption compared to previous generations while maintaining compatibility with existing design tools. The 'XL' designation indicates extended speed grades and improved I/O capabilities within the same macrocell structure.

Replacement Considerations

Direct pin-to-pin replacements are limited due to the obsolete status. Potential alternatives include other CPLDs from the same family with different package options, such as the XCR3128XL-7TQG144C, if pin count and package type allow. Designers should evaluate newer FPGA families for long-term supply stability.
