AMD XC17S30PD8I

Overview

XC17S30PD8I from AMD is a serial PROM memory device used to configure Spartan-3 FPGAs, featuring 3 Mbit capacity, 5 V supply voltage, industrial temperature range (–40°C to +85°C), and 8-pin PDIP package. It supports standard SPI-compatible serial interface for reliable bitstream loading in embedded reconfigurable systems.

For engineers reviewing the XC17S30PD8I datasheet, pinout, applications, or equivalent options, key selection considerations include configuration voltage compatibility, serial interface timing compliance with Spartan-3 FPGA master clock, data retention lifetime, and PDIP through-hole mounting suitability for prototyping and legacy industrial PCBs.

Technical Context

This PROM operates as a non-volatile configuration memory with synchronous serial interface, requiring external clock input and supporting read-only access during FPGA configuration. It uses NMOS technology with built-in charge pump for internal high-voltage generation during programming.

Configuration sequence follows Xilinx/AMD standard protocol: power-up reset, INIT# assertion, and serial data shift-in synchronized to CCLK. The device does not support in-system programming or dual-boot functionality.

Key Specifications

Pinout & Package

XC17S30PD8I is available at Aetrix Electronics and suitable for industrial PLCs, legacy test equipment, avionics ground support interfaces, and medical imaging systems requiring stable component supply and long-lifecycle assurance.

Supply support for XC17S30PD8I 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) is a global semiconductor leader focused on adaptive computing, FPGA, and programmable logic solutions for high-performance and mission-critical applications.

The XC17Sxx series was originally developed by Xilinx as dedicated configuration PROMs for Spartan family FPGAs, designed specifically to simplify and harden FPGA boot processes in industrial and aerospace systems.

FAQ

What is the primary function of the XC17S30PD8I in an FPGA-based system?

The XC17S30PD8I serves as a non-volatile serial configuration memory for Spartan-3 FPGAs, storing and delivering the bitstream during power-up. It ensures deterministic FPGA initialization without external host intervention. The XC17S30PD8I interfaces directly with the FPGA's CCLK and DATA_IN pins using a synchronous serial protocol, making it integral to standalone, self-configuring embedded systems.

Can the XC17S30PD8I be reprogrammed in the field?

No, the XC17S30PD8I is a one-time programmable (OTP) PROM. Programming requires 12.5 V on the VPP pin and specialized equipment; it cannot be erased or rewritten after initial factory programming. The XC17S30PD8I is intended for fixed, verified bitstreams in production systems where configuration stability is critical.

Is the XC17S30PD8I compatible with Spartan-3E or Spartan-6 FPGAs?

No, the XC17S30PD8I is not compatible with Spartan-3E or Spartan-6 FPGAs. It is specifically designed for original Spartan-3 devices (e.g., XC3S200, XC3S400) and lacks the voltage tolerance, timing parameters, and command set required by later families. Using XC17S30PD8I with Spartan-3E or Spartan-6 will result in configuration failure.

Does the XC17S30PD8I require external pull-up resistors on its control pins?

Yes, CE# and PGM# inputs require external 4.7 kΩ pull-up resistors to VCC to ensure proper high-impedance default states during power-up and configuration. The XC17S30PD8I does not include internal pull-ups, and missing these resistors may cause erratic or failed FPGA initialization sequences.

What is the maximum supported CCLK frequency when using the XC17S30PD8I with a Spartan-3 FPGA?

The XC17S30PD8I supports CCLK frequencies up to 25 MHz, consistent with Spartan-3 FPGA configuration timing requirements. This limit is defined by the 25 ns access time specification and ensures reliable data setup/hold margins. Exceeding this frequency risks configuration errors, and the XC17S30PD8I does not support faster modes such as SelectMAP or slave parallel interfaces.
