The XC17S100ASO20C is a Serial Configuration PROM (programmable read-only memory) from Xilinx, designed to configure Xilinx FPGAs (Field-Programmable Gate Arrays). These PROMs store the configuration bitstream that defines the functionality of the FPGA. Upon power-up, the FPGA reads the configuration data from the PROM, effectively programming the FPGA's logic and interconnections.

Applications

• Configuration storage for Xilinx FPGAs
• Boot-up configuration for embedded systems
• Storing program code for microcontrollers
• Data storage in non-volatile applications

Features

• 1 Mbit (128K x 8) memory capacity
• Serial interface for configuration data transfer
• Low power operation
• Fast configuration time
• Enduring data retention
• 20-pin Small Outline (SO) package
• Operating temperature: 0°C to +70°C

Benefits

• Provides a reliable and non-volatile way to store FPGA configuration data
• Enables rapid FPGA configuration upon power-up
• Reduces board space compared to parallel PROMs
• Simplifies system design
• Ensures correct FPGA functionality

Additional Details

The XC17S100ASO20C uses a serial interface to transfer configuration data to the FPGA. This serial configuration offers several advantages over parallel configuration, including reduced pin count, smaller board space requirements, and simpler routing. The 'XC17S' prefix indicates that it is part of Xilinx's serial configuration PROM family. The '100A' refers to the memory density (1 Mbit) and a specific performance grade. The 'SO20' denotes the 20-pin Small Outline package, which is suitable for surface mounting. The 'C' indicates the commercial temperature range (0°C to +70°C). These PROMs are typically programmed using a Xilinx programmer or a third-party programming tool that supports Xilinx devices. The configuration data is loaded into the PROM before it is used in the target system. The serial PROM is a critical component in Xilinx FPGA-based systems, ensuring that the FPGA is correctly configured and functions as intended. The datasheet should be consulted for precise programming procedures and timing diagrams.
