XC18V01SOG20C

Overview

The XC18V01SOG20C is a 1-Mbit Serial Configuration PROM designed for AMD/Xilinx FPGAs. It operates at a maximum frequency of 33 MHz with a supply voltage range of 3.0 V to 3.6 V. The device supports both parallel and serial programming modes, enabling in-system programmability. It is housed in a 20-pin SOIC package and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Supports in-system programmability for FPGA configuration
• Compatible with both parallel and serial programming interfaces
• Provides non-volatile storage for FPGA bitstream data

Applications

• Configuration of Xilinx Spartan-3E FPGAs
• Configuration of Xilinx Spartan-6 FPGAs
• Storage of configuration data for Virtex-4 devices

Procurement Notes

Verify the specific suffix 'G20' confirms the 20-pin SOIC package and commercial temperature grade. Ensure compatibility with the target FPGA family, as configuration PROMs are often architecture-specific. Confirm that the required memory density (1 Mbit) matches the design needs before ordering.

Selection Notes

Select this component when a small, cost-effective solution is needed for configuring low-to-medium complexity FPGAs. It is suitable for designs requiring in-system reconfiguration capabilities. Compare against higher-density variants if future-proofing or larger bitstreams are anticipated.

Part Context

This part belongs to the XC18V series of configuration PROMs from AMD/Xilinx. These devices are specifically engineered to store the configuration data required to initialize various FPGA families. They serve as the primary non-volatile memory source for loading user logic into the FPGA fabric upon power-up.

Replacement Considerations

The XC18V512SOG20C is a documented substitute offering higher capacity. Verify that the target FPGA can utilize the larger memory size and that pinout compatibility remains unchanged for direct replacement.
