AMD XC1701LPDG8I

Overview

XC1701LPDG8I from AMD is a serial PROM memory device used for configuring Xilinx FPGA devices, featuring 1 Mbit capacity, 5V supply voltage, and industrial temperature range (–40°C to +85°C); it supports serial configuration interface and is commonly deployed in embedded reconfigurable logic systems.

For engineers reviewing the XC1701LPDG8I datasheet, pinout, applications, or equivalent options, key selection criteria include configuration interface compatibility, VCC tolerance, data retention lifetime, programming voltage requirements, and industrial-grade thermal performance.

Technical Context

This device implements a one-time programmable (OTP) serial PROM architecture optimized for Xilinx 4000-series FPGA configuration. It uses CMOS technology with a standard SPI-compatible 3-wire serial interface (CLK, DATA, CE) and requires no external programming hardware beyond a compatible programmer.

Configuration data is loaded synchronously on the rising edge of CLK while CE is low; the device supports boundary-scan test access via dedicated pins and includes internal power-on reset circuitry to ensure reliable initialization during FPGA power-up sequences.

Key Specifications

Pinout & Package

XC1701LPDG8I is housed in an 8-pin plastic DIP (PDIP) package with 0.3-inch body width and through-hole mounting.

Applications

Equivalent & Alternatives

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

Compared with XC1701LPDG8I, XCF01SVO20C enables reconfiguration but demands level-shifting and alters power domain design, while XC1701LDV8I offers identical electrical behavior in a surface-mount form-neither is pin-compatible, and both require layout changes.

Availability

XC1701LPDG8I is available at Aetrix Electronics and suitable for industrial PLCs, legacy telecom infrastructure, test instrumentation, and avionics subsystems requiring stable component supply across extended production lifecycles.

Supply support for XC1701LPDG8I 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 XC1700 family.

The XC1700 series was originally designed by Xilinx to provide reliable, low-cost, one-time programmable configuration memory for its 4000-series FPGAs in industrial and aerospace applications.

FAQ

What is the programming method for XC1701LPDG8I?

The XC1701LPDG8I is programmed once using a dedicated PROM programmer applying 12.5 V to the VPP pin. Programming occurs serially via the CLK and DATA lines under CE control. No in-system programming capability exists-XC1701LPDG8I must be programmed before soldering into the target board.

Is XC1701LPDG8I compatible with Xilinx Virtex or Spartan FPGAs?

No, XC1701LPDG8I is specifically designed for Xilinx 4000-series FPGAs (XC4000E/XC4000XL). It lacks the timing, voltage, and protocol support required by Virtex or Spartan families, which use different configuration architectures and bitstream formats.

Does XC1701LPDG8I support JTAG boundary-scan configuration?

No, XC1701LPDG8I uses a proprietary 3-wire serial interface (CLK, DATA, CE) and does not implement IEEE 1149.1 JTAG. Some variants in the XC1700 family include JTAG-capable pins, but XC1701LPDG8I is not one of them.

Can XC1701LPDG8I be replaced with a modern flash-based PROM like XCFxx?

XC1701LPDG8I cannot be directly replaced with XCFxx devices without hardware modification. XCFxx parts operate at 3.3 V, use JTAG or master-serial mode, and require different power sequencing-XC1701LPDG8I's 5 V, 3-wire interface is electrically and logically incompatible.

What is the maximum clock frequency supported during XC1701LPDG8I configuration?

XC1701LPDG8I supports a maximum configuration clock frequency of 5 MHz, derived from its 200 ns access time specification. This aligns with the startup timing requirements of XC4000-series FPGAs and ensures reliable bitstream loading without setup/hold violations.
