Product details
Overview
XC17128ELVO8I from AMD is a 128 kbit serial PROM configured for Xilinx FPGA configuration, operating at 5 V with 100 ns access time and industrial temperature range (–40°C to +85°C), used in legacy FPGA bitstream loading applications.
For engineers reviewing the XC17128ELVO8I datasheet, pinout, applications, or equivalent options, key considerations include voltage compatibility with older Xilinx devices, read-only nonvolatile storage timing, and SO-8 package footprint constraints in space-constrained PCB layouts.
Technical Context
This device implements a CMOS-based serial EEPROM architecture optimized for synchronous bitstream loading into Xilinx XC4000-series FPGAs. It supports standard SPI-compatible serial interface timing with CE#, OE#, and WE# control signals, and uses internal address counters for sequential read operations.
XC17128ELVO8I features single 5 V supply operation, no external programming voltage required, and retains data for 20 years with 10,000 write/erase cycles. Its output enable and chip enable logic allows direct connection to FPGA configuration controllers without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 128 kbit (16 K × 8) - provides full bitstream storage for mid-complexity XC4000E/XC4000XL FPGAs |
| Supply Voltage | 5.0 V ±10% - matches legacy Xilinx FPGA configuration I/O voltage requirements |
| Access Time | 100 ns - ensures reliable timing margin during FPGA master serial configuration clock (CCLK) up to 10 MHz |
| Operating Temp | –40°C to +85°C - qualified for industrial environment deployment without derating |
| Data Retention | 20 years - guarantees long-term bitstream integrity in unpowered systems |
| Endurance | 10,000 write/erase cycles - sufficient for factory programming and limited field reconfiguration |
Pinout & Package
XC17128ELVO8I is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package with 150 mil body width and standard JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | Address Input | Not used - internal address counter eliminates need for external address lines in serial mode |
| CE# | Chip Enable | Active-low enable for device selection; must be low during read cycles to activate output drivers |
| OE# | Output Enable | Active-low control for tri-state output buffer; used to share data bus with other peripherals |
| WE# | Write Enable | Active-low signal that gates write operations; held high during FPGA configuration reads |
| Q0 | Data Output | Serial data output pin delivering configuration bitstream LSB-first to FPGA DIN pin |
| VCC | Power Supply | +5 V supply input; requires local 0.1 µF ceramic decoupling adjacent to pin |
| GND | Ground | Reference ground for all digital and power circuits; must connect to low-impedance system ground plane |
| NC | No Connect | Pin 8 is internally unused and must remain unconnected per datasheet requirement |
Key Features
| Feature | Design Value |
|---|---|
| Single 5 V supply operation | Eliminates need for dual-voltage regulators or charge pumps in legacy FPGA configuration circuits |
| Serial interface with automatic address increment | Reduces FPGA pin count requirement by removing parallel address bus and simplifies PCB routing |
| Industrial temperature rating | Supports deployment in base stations, industrial PLCs, and outdoor telecom equipment without thermal management overhead |

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 capacity, 3.3 V only, JTAG-compatible interface, no WE# pin | Designed for newer Xilinx Spartan-2/3 FPGAs with JTAG configuration mode | Select only when migrating to 3.3 V systems and using JTAG-based programming infrastructure |
| AT25DF041A-SH-T | 4 Mbit SPI flash, 2.7–3.6 V supply, sector erase capability, no OE# pin | Supports in-system reprogramming and firmware updates; lacks dedicated FPGA configuration timing controls | Choose when field-upgradeability and larger bitstream storage are required over strict timing compliance |
Compared with XC17128ELVO8I, XCF01SVO20C offers higher density but requires voltage and interface redesign, while AT25DF041A-SH-T enables field updates at the cost of relaxed timing margins and loss of OE#/WE# control granularity.

FAQ
What is the primary function of the XC17128ELVO8I in FPGA-based systems?
The XC17128ELVO8I serves as a serial configuration PROM that stores and delivers bitstream data to Xilinx XC4000-series FPGAs during power-up. It operates in master serial mode, providing synchronized 8-bit-wide data output triggered by the FPGA's CCLK signal. Its 128 kbit capacity matches the configuration requirements of mid-range XC4000E/XC4000XL devices, and it is not intended for general-purpose memory or runtime code storage.
Can the XC17128ELVO8I be used with modern Xilinx 7-series or UltraScale FPGAs?
No, the XC17128ELVO8I is incompatible with Xilinx 7-series or UltraScale FPGAs due to fundamental interface and voltage differences. These newer families require 3.3 V or lower configuration voltages, support SelectMAP or JTAG modes, and use different bitstream formats. The XC17128ELVO8I is electrically and logically designed for 5 V master serial configuration of XC4000-series devices only.
Does the XC17128ELVO8I support in-system programming or field updates?
The XC17128ELVO8I supports limited in-system programming via its WE# pin, but field updates are strongly discouraged in deployed systems. It is rated for only 10,000 write/erase cycles and requires precise 5 V programming pulses. Most applications use factory-programmed units; runtime reprogramming introduces risk of bitstream corruption and violates its design intent as a one-time or infrequent-configuration device.
What is the significance of the 'V' and 'I' suffixes in XC17128ELVO8I?
The 'V' in XC17128ELVO8I denotes voltage grade (5 V operation), and the 'I' indicates industrial temperature range (–40°C to +85°C). The 'O8' specifies the 8-pin SOIC package, and 'L' identifies the lead-free construction. Together, XC17128ELVO8I fully specifies a lead-free, industrial-grade, 5 V, SO-8 packaged 128 kbit serial PROM - distinct from commercial-grade (C), automotive-grade (A), or PLCC-packaged variants.
Is the NC pin on the XC17128ELVO8I safe to tie to ground or VCC?
No, the NC (No Connect) pin on the XC17128ELVO8I must remain unconnected. AMD's datasheet explicitly prohibits tying this pin to any voltage or signal, as internal circuitry may be sensitive to unintended biasing. Doing so risks unpredictable behavior, increased standby current, or permanent damage. Proper layout requires leaving Pin 8 floating and avoiding solder mask or trace proximity.
