XC17S150ASO20C

Overview

The AMD XC17S150ASO20C is a 1.5 Mbit serial Programmable Read-Only Memory (PROM) designed for the configuration of Field-Programmable Gate Arrays (FPGAs). This One-Time Programmable (OTP) device operates within a commercial temperature range and is housed in a 20-pin Small Outline Integrated Circuit (SOIC) package.

Feature Summary

• Provides non-volatile storage for FPGA configuration data
• Supports serial interface programming for system integration
• Designed for reliable operation in commercial temperature environments

Applications

• Configuration of AMD/Xilinx FPGAs
• Embedded system boot memory
• Industrial control hardware initialization

Procurement Notes

Verify the specific suffix 'A' and 'SO20C' to confirm the commercial temperature grade and 20-pin SOIC package variant. Ensure compatibility with the target FPGA's configuration mode requirements before procurement, as OTP devices are non-reprogrammable once programmed.

Selection Notes

Select this component when a dedicated serial PROM is required for FPGA configuration rather than using volatile memory with external battery backup. The 1.5 Mbit capacity suits smaller to medium-sized FPGA designs. Confirm that the host system supports the necessary serial protocol for reading configuration data from this OTP device.

Part Context

This part belongs to the AMD XC17 series of serial PROMs, historically used for configuring Xilinx FPGAs. It serves as a cost-effective solution for storing bitstreams in embedded applications where reprogramming is not required after initial deployment.

Replacement Considerations

Check for direct pin-compatible successors such as the XC17S150E or other XC17S variants with higher density if design margins allow. Verify that any substitute maintains the same serial interface timing and voltage levels.
