AMD XC17S10VO8I

Overview

XC17S10VO8I from AMD is a serial configuration PROM designed for Xilinx Spartan-3 FPGAs, providing 1 Mbit (128K × 8) non-volatile storage in an 8-pin SOIC package with 5V supply compatibility and 10 MHz read access speed. It serves as the primary bitstream loader during FPGA power-up in industrial control and test equipment.

For engineers reviewing the XC17S10VO8I datasheet, pinout, applications, or equivalent options, key selection criteria include voltage tolerance (5V), interface timing (10 MHz max clock), package footprint (SOIC-8), and FPGA family-specific configuration protocol support.

Technical Context

This device implements a synchronous serial interface compliant with Xilinx's 3-wire configuration protocol (DIN, DOUT, CCLK), supporting master-mode read-only operation. It requires no external address lines and uses internal address counters incremented on each CCLK rising edge.

Configuration data is stored in NMOS floating-gate memory cells, enabling guaranteed 20-year data retention and 10,000 program/erase cycles. The device operates across –40°C to +85°C and supports both power-on reset and active-low PROGRAM pin initiation.

Key Specifications

FAQ

Is XC17S10VO8I pin-compatible with Xilinx XC17S10VO8I?

Yes, XC17S10VO8I is manufactured by AMD as a direct continuation of the Xilinx XC17S10VO8I part. It maintains identical pinout, electrical characteristics, timing behavior, and SOIC-8 package dimensions. No PCB or schematic changes are required when substituting XC17S10VO8I for legacy Xilinx-labeled units in existing designs.

What FPGA families does XC17S10VO8I support?

XC17S10VO8I is specifically designed for Xilinx Spartan-3 FPGAs, including XC3S50 through XC3S1000. It delivers the full 128K × 8 bitstream required for these devices and complies with their 3-wire serial configuration protocol. It is not compatible with Spartan-2, Virtex, or newer 7-series FPGAs due to protocol and voltage differences.

Does XC17S10VO8I require external pull-up resistors?

XC17S10VO8I requires a 4.7 kΩ pull-up resistor on the PROGRAM pin to ensure proper initialization during power-up. DOUT and CCLK lines may need termination depending on trace length and FPGA input impedance, but no pull-ups are needed on DIN or A0 since those pins are unused in master read mode per the Xilinx configuration specification for XC17S10VO8I.

Can XC17S10VO8I be reprogrammed in-system?

No, XC17S10VO8I is a one-time programmable (OTP) PROM. Reprogramming requires removal from the PCB and use of a dedicated PROM programmer. Field updates are not supported. For in-system reprogrammability, consider SPI Flash alternatives-but note that XC17S10VO8I's native Xilinx protocol would no longer apply.

What is the maximum configuration clock frequency supported by XC17S10VO8I?

XC17S10VO8I supports a maximum CCLK frequency of 10 MHz, as specified in the AMD/Xilinx datasheet. Exceeding this limit risks read errors or incomplete bitstream loading. This timing aligns precisely with the Spartan-3 FPGA's configuration clock specification, ensuring reliable startup across temperature and voltage corners for XC17S10VO8I.
