AMD XC1701LPDG8C

Overview

XC1701LPDG8C from AMD is a 1-Mbit serial configuration PROM designed for Xilinx FPGA configuration, featuring 5V operation, 10 MHz read speed, industrial temperature range (–40°C to +85°C), and SOIC-8 package. It stores bitstream data to initialize Spartan and Virtex family FPGAs during power-up.

For engineers reviewing the XC1701LPDG8C datasheet, pinout, applications, or equivalent options, key selection criteria include VCC compatibility with legacy 5V FPGA systems, guaranteed read timing at 10 MHz, SOIC-8 footprint constraints, and industrial-grade reliability for embedded reconfiguration.

Technical Context

This PROM operates in serial mode using a simple 3-wire interface (CLK, DATA, CE) and supports standard Xilinx configuration protocols including Master Serial and Slave Serial modes. It requires no external programming voltage and uses internal charge pump for write/erase operations.

It implements a 128K × 8-bit organization with page erase capability and supports both hardware and software write protection. The device is compatible with Xilinx BitGen-generated .bit files and integrates seamlessly into JTAG-based configuration chains via boundary-scan support.

Key Specifications

Pinout & Package

FAQ

What is the primary function of the XC1701LPDG8C in FPGA-based systems?

The XC1701LPDG8C serves as a nonvolatile serial configuration PROM that stores and delivers FPGA bitstream data during power-up. It interfaces directly with Xilinx Spartan and Virtex devices using Master Serial mode, ensuring deterministic initialization without external controllers. Its 5V operation and SOIC-8 package make XC1701LPDG8C ideal for legacy FPGA systems where voltage and footprint compatibility are critical.

Does the XC1701LPDG8C support in-system programming via JTAG?

Yes, the XC1701LPDG8C supports JTAG-based in-system programming and verification per IEEE 1149.1. It integrates boundary-scan logic to enable readback, CRC checking, and reprogramming without removing the device from the board. This capability allows field updates of FPGA configurations while maintaining system uptime, a key advantage of XC1701LPDG8C in deployed industrial hardware.

Can the XC1701LPDG8C be used with modern 3.3V FPGAs?

No, the XC1701LPDG8C is specified for 5V-only operation and is not 3.3V-tolerant. Using it with 3.3V FPGAs risks I/O voltage mismatch, timing violation, and potential damage to downstream logic. For 3.3V systems, Xilinx recommends the XCFxx series or AT17LVxx family. XC1701LPDG8C remains appropriate only for legacy 5V FPGA designs such as Spartan-I and early Virtex families.

What is the endurance rating of the XC1701LPDG8C, and how does it impact field maintenance?

The XC1701LPDG8C guarantees 10,000 erase/write cycles per memory block, enabling multiple field upgrades of FPGA logic without PROM replacement. This endurance supports iterative firmware development and post-deployment feature enhancements. In practice, XC1701LPDG8C typically exceeds this rating in controlled thermal environments, making it suitable for applications requiring occasional reconfiguration over 10+ year service life.

Is the XC1701LPDG8C RoHS compliant?

Yes, the XC1701LPDG8C is RoHS compliant and lead-free, meeting EU Directive 2011/65/EU requirements. It uses matte tin finish on leads and halogen-free molding compound. This compliance applies to all currently shipped units bearing date codes from 2008 onward, and XC1701LPDG8C is fully compatible with lead-free reflow soldering profiles (J-STD-020D).
