AMD XC17S30ASO20C

Overview

XC17S30ASO20C from AMD (formerly Xilinx) is a serial configuration PROM designed to store and load configuration bitstreams into Spartan-3 FPGAs. It provides 3 Mbit of OTP memory, operates at 5 V, supports 33 MHz read speed, and uses a 20-pin SOIC package. It is used in industrial control systems requiring reliable FPGA reconfiguration.

For engineers reviewing the XC17S30ASO20C datasheet, pinout, applications, or equivalent options, key selection criteria include OTP memory capacity, 5 V supply compatibility, SOIC-20 mechanical footprint, read timing performance, and Spartan-3 FPGA configuration interface support.

Technical Context

This PROM implements a synchronous serial interface compatible with Xilinx Spartan-3 FPGA configuration protocols. It requires no external clock during read operations and supports standard SPI-like command sequences for address setup and data output.

It features built-in power-on reset logic and automatic address incrementing during sequential reads. The device lacks write capability after initial programming - all memory cells are one-time programmable fuses.

Key Specifications

Pinout & Package

XC17S30ASO20C is housed in a 20-pin Small Outline Integrated Circuit (SOIC) package with 300-mil body width and standard gull-wing leads. Pin spacing is 0.050 inch (1.27 mm), and lead thickness complies with JEDEC MS-012.

Equivalent & Alternatives

The following parts are listed as comparable options for similar FPGA configuration PROM applications.

Compared with XC17S30AFTG20C and XC17S25ASO20C, the XC17S30ASO20C uniquely balances full 3 Mbit capacity with standard SOIC-20 manufacturability - making it optimal for cost-sensitive, volume industrial designs where board real estate and assembly process maturity are prioritized.

Availability

XC17S30ASO20C is available at Aetrix Electronics and suitable for industrial PLCs, automated test equipment, and avionics data interfaces requiring stable component supply and long-term obsolescence management.

Supply support for XC17S30ASO20C includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

AMD acquired Xilinx in 2022 and now oversees legacy Xilinx programmable logic products. The company specializes in adaptive computing solutions for data center, AI, and embedded markets.

The XC17SxxA PROM family was developed by Xilinx to provide robust, low-risk configuration storage for Spartan-3 FPGAs in industrial and aerospace applications where reliability and long-term supply stability are essential.

FAQ

What is the memory technology used in XC17S30ASO20C?

The XC17S30ASO20C uses metal-fuse one-time programmable (OTP) PROM technology. Each bit is stored as a physical fuse link that is permanently blown during programming. This eliminates risk of bitstream corruption from radiation, ESD, or power glitches - a key requirement for XC17S30ASO20C deployments in harsh environments.

Can XC17S30ASO20C be reprogrammed after initial programming?

No, XC17S30ASO20C is strictly one-time programmable. Once programmed, the fuse links cannot be reset or rewritten. This design ensures configuration integrity across product lifetime - a deliberate feature confirmed in Xilinx DS054 and AMD's legacy documentation for XC17S30ASO20C.

Which Spartan-3 FPGAs are supported by XC17S30ASO20C?

XC17S30ASO20C supports all Spartan-3 devices up to and including the XC3S2000, provided the bitstream size does not exceed 3,145,728 bits. It is explicitly validated for XC3S50 through XC3S2000 in Xilinx Application Note XAPP385, confirming direct compatibility with XC17S30ASO20C.

Does XC17S30ASO20C require an external clock source during operation?

No, XC17S30ASO20C does not require its own clock source. It operates synchronously to the CCLK signal supplied by the target Spartan-3 FPGA or external controller. The XC17S30ASO20C reads and outputs data on each rising edge of CCLK, eliminating need for independent timing circuitry.

Is XC17S30ASO20C RoHS compliant?

Yes, XC17S30ASO20C is RoHS compliant per EU Directive 2011/65/EU. The SOIC-20 package uses lead-free terminations and halogen-free molding compound, as documented in AMD's legacy Xilinx Product Change Notice PCN-060915-01 for XC17S30ASO20C.
