AMD XC17S30XLPDG8C

Overview

XC17S30XLPDG8C from AMD (formerly Xilinx) is a serial configuration PROM designed to store and load bitstream data for Spartan-XL FPGAs. It provides 3 Mbit storage capacity, supports 3.3 V single-supply operation, features programmable security bit, and operates across industrial temperature range (–40°C to +85°C). It is used in FPGA-based embedded control systems requiring nonvolatile configuration storage.

For engineers reviewing the XC17S30XLPDG8C datasheet, pinout, applications, or equivalent options, key selection criteria include serial interface compatibility with Spartan-XL devices, security bit enablement, industrial temperature rating, and PDIP-8 package footprint constraints.

Technical Context

The XC17S30XLPDG8C implements a synchronous serial interface compliant with Xilinx's proprietary configuration protocol for Spartan-XL family FPGAs. It uses CMOS technology with internal voltage regulation and includes a dedicated PROGRAM pin for reprogramming control and an INIT pin for FPGA initialization status feedback.

It supports both master and slave serial configuration modes, delivers guaranteed read access time of 25 ns, and integrates a hardware security bit that permanently disables further programming once set - preventing unauthorized bitstream modification or cloning.

Key Specifications

FAQ

What is the primary function of the XC17S30XLPDG8C in an FPGA system?

The XC17S30XLPDG8C serves as a nonvolatile configuration PROM that stores and delivers the bitstream to initialize Spartan-XL FPGAs at power-up. It operates in synchronous serial mode, driven by the FPGA's configuration clock, and supports automatic loading without external microcontroller intervention. The XC17S30XLPDG8C ensures deterministic startup and retains configuration data across power cycles.

Does the XC17S30XLPDG8C support reprogramming in-system?

Yes, the XC17S30XLPDG8C supports in-system programming via its PROGRAM pin, which initiates an erase-and-write cycle when pulsed low after power stabilization. Reprogramming requires a compatible Xilinx programming tool and adheres to voltage and timing specifications in the official datasheet. Once the security bit is set, the XC17S30XLPDG8C permanently disables further programming.

Can the XC17S30XLPDG8C be used with newer Xilinx FPGA families like Spartan-3 or Artix-7?

No, the XC17S30XLPDG8C is specifically designed for Spartan-XL FPGAs and is not compatible with Spartan-3, Spartan-6, or Artix-7 families due to differences in configuration protocol, voltage requirements, and bitstream format. Using it with non-Spartan-XL devices will result in failed initialization. The XC17S30XLPDG8C interface is proprietary and not backward- or forward-compatible across FPGA generations.

What does the NC pin on the XC17S30XLPDG8C signify, and how should it be handled?

The NC (No Connect) pin on the XC17S30XLPDG8C is internally unconnected and must not be bonded to any signal or power net. Per Xilinx design guidelines, it should remain electrically floating or be tied to ground through a high-value resistor (e.g., 10 MΩ) to prevent noise coupling. Improper handling of the NC pin may cause erratic behavior during configuration, especially in noisy industrial environments where the XC17S30XLPDG8C is commonly deployed.

How does the security bit on the XC17S30XLPDG8C function, and is it reversible?

The security bit on the XC17S30XLPDG8C is a one-time-programmable fuse that, once set, permanently disables all future programming operations including erase and write. It is activated by a specific voltage pulse sequence applied to the PROGRAM pin during programming. This feature prevents bitstream cloning or unauthorized firmware updates. The security bit cannot be cleared or reversed - the XC17S30XLPDG8C remains read-only after activation.
