AMD XC1701PD8I

Overview

XC1701PD8I from AMD is a configuration PROM for Xilinx FPGA devices, providing serial bitstream storage with 1 Mbit capacity, 5 V supply voltage, and industrial temperature range (–40°C to +85°C); used in embedded reconfigurable systems requiring nonvolatile, single-supply configuration memory.

For engineers reviewing the XC1701PD8I datasheet, pinout, applications, or equivalent options, key selection criteria include serial interface compatibility with Xilinx Virtex and Spartan families, 5 V read/write voltage tolerance, and industrial-grade reliability for field-deployed logic systems.

Technical Context

This PROM operates in master serial mode to configure Xilinx FPGAs during power-up, supporting standard Xilinx SelectMAP and serial configuration protocols. It uses CMOS EEPROM technology with internal charge-pump circuitry enabling 5 V-only programming without external high-voltage supplies.

Timing is synchronized to the FPGA's CCLK signal during configuration; access time is 150 ns max at 5 V, and write cycle time is 10 ms typical per byte. The device includes built-in write protection via software and hardware (WP pin) controls.

Key Specifications

Pinout & Package

XC1701PD8I is housed in an 8-pin plastic DIP (PDIP-8) package with 0.3-inch body width and through-hole mounting. Pin functions are electrically and mechanically compatible with industry-standard serial PROM footprints for Xilinx configuration interfaces.

The XC1701PD8I belongs to the Xilinx XC1700 series of serial configuration PROMs, designed specifically to provide reliable, single-supply bitstream storage for Virtex and Spartan family FPGAs in industrial and embedded applications.

FAQ

What is the primary function of the XC1701PD8I in an FPGA-based system?

The XC1701PD8I serves as a serial configuration PROM that stores and delivers the bitstream to Xilinx Spartan-II and Virtex FPGAs during power-up. It operates in master serial mode, synchronizing with the FPGA's CCLK signal. Its 1 Mbit capacity supports full configuration images for these target devices, and it is essential for deterministic, repeatable FPGA initialization without external programming hardware.

Does the XC1701PD8I require a high-voltage supply for programming?

No, the XC1701PD8I does not require an external high-voltage supply. It integrates an internal charge-pump circuit enabling full 5 V-only programming and erasing. This eliminates the need for 12 V or other auxiliary voltages, simplifying system-level power design and making it suitable for field-programmable applications where only a 5 V rail is available.

Is the XC1701PD8I compatible with modern Xilinx FPGA families like Spartan-6 or Artix-7?

No, the XC1701PD8I is not compatible with Spartan-6, Artix-7, or newer Xilinx FPGA families. It is specifically designed for legacy Xilinx devices including Spartan-II, Virtex, and XC9500 CPLDs. These newer families use different configuration protocols (e.g., SelectMAP with wider buses or JTAG-based fallback), and the XC1701PD8I lacks the required signaling or timing support.

What package type and mounting style does the XC1701PD8I use?

The XC1701PD8I uses an 8-pin plastic dual in-line package (PDIP-8) with 0.3-inch body width and through-hole leads. This package supports manual soldering, socket-based prototyping, and field replacement. Its pinout aligns with industry-standard serial PROM footprints used in Xilinx reference designs for Spartan-II and Virtex configuration interfaces.

How is write protection implemented on the XC1701PD8I?

The XC1701PD8I implements write protection via both hardware and software methods. The WP# (Write Protect) pin, when pulled low, physically disables all write and erase operations regardless of command sequence. Additionally, software write protection can be enabled by setting internal lock bits, which persist across power cycles until explicitly cleared using the correct unlock sequence and voltage conditions.
