Product details
Overview
XC1701LPCG20I from AMD is a configuration PROM for Spartan and Virtex FPGAs, providing 1-Mbit serial EEPROM storage in a 20-pin PLCC package with 5V operation, 100 kHz clock frequency, and industrial temperature range (–40°C to +85°C); used to store bitstream configuration data during FPGA power-up.
For engineers reviewing the XC1701LPCG20I datasheet, pinout, applications, or equivalent options, key selection factors include serial interface compatibility with Xilinx FPGA configuration modes, industrial-grade reliability, 5V VCC tolerance, and PLCC-20 footprint suitability for legacy PCB layouts.
Technical Context
The XC1701LPCG20I implements a synchronous serial interface compliant with Xilinx's SelectMAP and Master Serial configuration protocols, supporting both active-high and active-low chip select logic. It uses internal address auto-increment and supports read-only sequential access for FPGA bitstream loading.
Designed exclusively for FPGA configuration memory, it lacks write-enable protection during normal operation and relies on external hardware reset sequencing to ensure deterministic initialization timing with Spartan-II and Virtex-E families.

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCF01SVO20C | 1 Mbit, 3.3V-only supply, VO20 package (20-pin TSSOP) | Requires level-shifting or redesign for 5V systems; smaller footprint | Select when migrating to 3.3V FPGA platforms and board space is constrained |
| AT17LV010-10JU | 1 Mbit, 3.3V/2.5V dual-supply, PLCC-20, 10 MHz clock | Higher speed but incompatible voltage domain; no 5V support | Choose only if system already uses 3.3V configuration bus and faster load time is critical |
Compared with XC1701LPCG20I, XCF01SVO20C demands voltage translation in legacy 5V designs, while AT17LV010-10JU offers faster clocking but eliminates 5V interoperability-making XC1701LPCG20I the sole direct-fit solution for unmodified industrial 5V FPGA carrier boards.

FAQ
Is XC1701LPCG20I compatible with Spartan-3 FPGAs?
No, XC1701LPCG20I is not compatible with Spartan-3 FPGAs. It is designed for Spartan-II and Virtex-E families only. Spartan-3 requires different configuration protocol timing and voltage levels. Using XC1701LPCG20I with Spartan-3 may result in failed configuration or unpredictable behavior. Always verify FPGA family compatibility in the official Xilinx configuration guide before integration.
What is the maximum configuration clock frequency supported by XC1701LPCG20I?
The maximum configuration clock frequency supported by XC1701LPCG20I is 100 kHz. This limit ensures reliable data sampling and internal address increment timing across the full industrial temperature range (–40°C to +85°C) and 5V supply tolerance. Exceeding this frequency risks bitstream read errors and FPGA configuration failure.
Does XC1701LPCG20I support in-system programming (ISP)?
No, XC1701LPCG20I does not support in-system programming. It is a one-time programmable (OTP) or factory-programmed device with read-only serial access during FPGA configuration. Programming must be performed off-line using dedicated PROM programmers prior to board assembly. No write command set or erase functionality is implemented.
Can XC1701LPCG20I be used in place of XC1701LPCG20C?
Yes, XC1701LPCG20I can replace XC1701LPCG20C in most designs. The 'I' suffix denotes industrial temperature grade (–40°C to +85°C), while 'C' indicates commercial grade (0°C to +70°C). All electrical specifications, pinout, and timing are identical. The XC1701LPCG20I provides extended thermal margin for harsher environments without any circuit modification.
What is the data retention specification for XC1701LPCG20I?
XC1701LPCG20I guarantees minimum data retention of 20 years at +85°C and indefinite retention at lower temperatures. This specification applies to factory-programmed devices stored and operated within rated voltage and temperature limits. Data integrity is maintained without refresh cycles due to nonvolatile EEPROM cell architecture.
