AMD XC17128ELVO8C

Overview

XC17128ELVO8C from AMD is a 128-kbit serial PROM configured for Xilinx FPGA configuration, operating at 5 V with 8-pin SOIC package and 10 MHz max clock frequency, used in industrial FPGA boot loading systems.

For engineers reviewing the XC17128ELVO8C datasheet, pinout, applications, or equivalent options, key considerations include voltage compatibility with Xilinx 3.3V/5V I/O banks, serial configuration interface timing, PROM endurance (10,000 write cycles), and industrial temperature range support.

Technical Context

This PROM implements a synchronous serial interface compatible with Xilinx Virtex and Spartan families, supporting master serial mode only. It uses CMOS technology with TTL-compatible inputs and open-drain outputs for data output control.

Configuration data is stored in non-volatile EEPROM cells. The device requires external power-up sequencing to ensure reliable FPGA initialization, and supports active-low chip select and data output enable controls.

Key Specifications

Pinout & Package

8-pin SOIC (Small Outline Integrated Circuit) package, 150 mil width, JEDEC MS-012AC compliant, surface-mountable with standard reflow profile.

XC17128ELVO8C is available at Aetrix Electronics and suitable for industrial PLCs, automated test equipment, and legacy telecom modules requiring stable component supply and long-term obsolescence management.

Supply support for XC17128ELVO8C 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 (Advanced Micro Devices) is a U.S.-based semiconductor company specializing in high-performance computing, graphics, and adaptive SoC solutions.

The XC1700 family was developed by AMD specifically for Xilinx FPGA configuration, targeting industrial and communications systems requiring reliable, low-cost serial PROMs.

FAQ

What is the maximum configuration clock frequency supported by XC17128ELVO8C?

The XC17128ELVO8C supports a maximum serial clock frequency of 10 MHz. This value is specified under standard operating conditions (5 V, 25°C) and defines the upper timing boundary for reliable data transfer during FPGA configuration. Exceeding this frequency may result in bit errors or incomplete loading. The XC17128ELVO8C datasheet confirms this limit applies to both read and programming operations.

Is XC17128ELVO8C compatible with Xilinx Spartan-3 FPGAs?

No, XC17128ELVO8C is not compatible with Xilinx Spartan-3 FPGAs. It was designed for Xilinx 4000E/XL and early Virtex families, which use 5 V-tolerant configuration interfaces. Spartan-3 requires 3.3 V configuration PROMs like XCFxx series, and its bitstream format and command protocol differ. Using XC17128ELVO8C with Spartan-3 will result in failed initialization.

Does XC17128ELVO8C require an external pull-up resistor on the data output pin?

Yes, XC17128ELVO8C requires an external pull-up resistor on pin 5 (D0), as it features an open-drain output structure. A 4.7 kΩ resistor to VCC is recommended per Xilinx Application Note XAPP119. Without this resistor, the D0 line cannot assert a valid logic-high level, causing configuration failure or indeterminate FPGA behavior during boot.

What is the write endurance specification for XC17128ELVO8C?

The XC17128ELVO8C has a write endurance rating of 10,000 program/erase cycles per memory location. This reflects the guaranteed number of times a given address can be rewritten before potential data retention failure. Field updates should be limited to this threshold; for systems requiring frequent reconfiguration, alternative non-volatile storage or external configuration controllers should be considered.

Can XC17128ELVO8C operate outside the industrial temperature range?

No, XC17128ELVO8C is characterized and qualified only for operation between –40°C and +85°C. Operation outside this range is not guaranteed and may cause timing violations, increased bit error rates, or permanent data corruption. The device does not meet commercial (0°C to +70°C) or extended temperature grades; its qualification aligns strictly with industrial environmental standards.
