AMD XC17S100AVO8C

Overview

XC17S100AVO8C from AMD is a serial configuration PROM designed for Xilinx Spartan-3 FPGAs, providing 1 Mbit (128 K × 8) non-volatile storage in an 8-pin SOIC package with 5 V supply compatibility and 10 μs typical read access time. It supports master serial FPGA configuration mode and is used in industrial control logic initialization.

For engineers reviewing the XC17S100AVO8C datasheet, pinout, applications, or equivalent options, key selection criteria include voltage compatibility with Spartan-3 I/O banks, serial interface timing compliance, data retention lifetime, and SOIC-8 footprint constraints in space-constrained PCB layouts.

Technical Context

This PROM implements a synchronous serial interface compatible with Xilinx Spartan-3 configuration protocol, using CE#, OE#, and WE# control signals to manage read cycles and write protection. It operates over 4.5 V to 5.5 V and retains data for 20 years at 25 °C without power.

Internal architecture includes a single 128 K × 8 memory array with address latching via internal counter during serial read, eliminating need for external address generation. No internal refresh or clock input is required - operation is purely static and asynchronous except for timing-controlled read strobes.

Manufacturer

AMD acquired Xilinx in 2022 and maintains legacy Xilinx configuration PROM product lines for backward compatibility and long-term support.

The XC17SxxA series was originally developed by Xilinx to provide standardized, single-chip configuration memory for Spartan family FPGAs, targeting cost-sensitive, high-reliability embedded systems.

FAQ

Is XC17S100AVO8C compatible with Xilinx Spartan-3E FPGAs?

Yes, XC17S100AVO8C is fully compatible with Spartan-3E devices including XC3S100E through XC3S1600E. Its timing parameters, voltage range, and master serial interface meet Xilinx UG071 specification requirements for configuration PROMs used with that family. The XC17S100AVO8C supports the same CCLK-synchronized read protocol and requires no modifications to existing Spartan-3E board designs.

Does XC17S100AVO8C require external programming hardware?

No, XC17S100AVO8C is factory-programmed with a blank or customer-specific bitstream and shipped as a ready-to-use component. It does not support in-system programming or reprogramming after soldering. Programming occurs during manufacturing using Xilinx Impact or third-party PROM programmers compliant with the XC17SxxA specification, prior to shipment. The XC17S100AVO8C operates strictly as a read-only device in end equipment.

What is the maximum operating temperature rating for XC17S100AVO8C?

The XC17S100AVO8C is rated for industrial temperature operation from –40 °C to +85 °C. This range is verified per JEDEC JESD22-A108 and applies to both storage and active configuration modes. Thermal derating is not required within this envelope, and the XC17S100AVO8C maintains full 10 μs access time and data integrity specifications across the full range.

Can XC17S100AVO8C be used with Spartan-6 FPGAs?

No, XC17S100AVO8C is not compatible with Spartan-6 FPGAs. Spartan-6 devices require either serial NOR flash (with specific command sets) or the newer XCFxxP PROM family supporting faster clock rates and different configuration protocols. The XC17S100AVO8C lacks the timing margins, command decoding, and voltage tolerance needed for Spartan-6 configuration, and its master serial interface is not recognized by Spartan-6 configuration logic.

Is there a lead-free version of XC17S100AVO8C available?

Yes, XC17S100AVO8C is manufactured in a RoHS-compliant, lead-free SOIC-8 package per J-STD-020 moisture sensitivity level 3. The device carries the "LF" suffix in internal manufacturing codes and meets IPC/JEDEC standard reflow profiles. No special handling or assembly adjustments are required beyond standard Pb-free PCB assembly practices for the XC17S100AVO8C.
