AMD XC17S10XLVO8I

Overview

XC17S10XLVO8I from AMD is a serial configuration PROM designed for Xilinx Spartan-2 FPGAs, providing 1 Mbit (128K × 8) non-volatile storage in an 8-pin SOIC package with 5V operation and 10 MHz read speed. It supports master serial mode configuration of XC2S10 and related devices in industrial temperature range (–40°C to +85°C).

For engineers reviewing the XC17S10XLVO8I datasheet, pinout, applications, or equivalent options, key selection factors include voltage compatibility (5V-only), serial interface timing, industrial-grade temperature rating, and FPGA configuration sequence support.

Technical Context

This PROM operates exclusively in master serial mode, delivering configuration bitstreams to Spartan-2 FPGAs via a synchronous serial interface using CLK, DATA, and INIT pins. It requires no external address decoding and relies on FPGA-initiated read cycles.

Configuration begins upon FPGA power-up and INIT deassertion; XC17S10XLVO8I outputs data on the falling edge of CLK with tACC ≤ 100 ns and tPD ≤ 80 ns. The device lacks write capability after factory programming and does not support in-system reprogramming.

Key Specifications

Pinout & Package

XC17S10XLVO8I is housed in an 8-pin Small Outline Integrated Circuit (SOIC) package with standard 1.27 mm pitch and gull-wing leads. Pin functions are defined per Xilinx configuration protocol requirements.

Equivalent & Alternatives

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

Compared with XCF01SVO20C and XC17S10LV08I, XC17S10XLVO8I provides guaranteed 5V timing margins and industrial temperature reliability without interface translation, making it the sole drop-in solution for legacy 5V Spartan-2 systems requiring zero-layout change.

Availability

XC17S10XLVO8I is available at Aetrix Electronics and suitable for industrial control, medical imaging subsystems, and avionics ground support equipment requiring stable component supply across extended product lifecycles.

Supply support for XC17S10XLVO8I 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 configuration PROM product lines including the XC17Sxx family.

The XC17Sxx series was originally developed by Xilinx to provide cost-optimized, single-chip configuration solutions for Spartan-2 FPGAs in volume industrial applications.

FAQ

Is XC17S10XLVO8I compatible with Xilinx Spartan-3 FPGAs?

No. XC17S10XLVO8I is specifically designed for Spartan-2 FPGAs such as XC2S10. Spartan-3 devices require different configuration protocols and voltage levels. Using XC17S10XLVO8I with Spartan-3 will result in failed initialization or unpredictable behavior. Always verify FPGA family compatibility before selecting a configuration PROM.

What is the maximum clock frequency supported by XC17S10XLVO8I during configuration?

XC17S10XLVO8I supports a maximum configuration clock frequency of 10 MHz, corresponding to a minimum clock period of 100 ns. This limit is defined by tACC (100 ns max) and tPD (80 ns max) timing parameters. Exceeding 10 MHz may cause bitstream corruption or FPGA configuration failure.

Can XC17S10XLVO8I be reprogrammed in the field?

No. XC17S10XLVO8I is a one-time programmable (OTP) PROM factory-programmed with a fixed bitstream. It lacks erase or write circuitry and cannot be modified after shipment. For field-upgradable configuration, consider XCFxx series PROMs with JTAG support.

Does XC17S10XLVO8I require external pull-up resistors on its control pins?

Yes. XC17S10XLVO8I requires a 4.7 kΩ pull-up resistor on the INIT pin and 10 kΩ pull-ups on CE and OE to ensure proper master serial mode operation. These resistors establish defined logic states during power-up and prevent floating inputs that could disrupt configuration sequencing.

What is the data retention specification for XC17S10XLVO8I?

XC17S10XLVO8I guarantees data retention of 20 years at +85°C and indefinite retention at lower temperatures per Xilinx specification. This applies to the factory-programmed bitstream and assumes proper handling, soldering, and operating conditions within rated voltage and temperature limits.
