Product details
Overview
XC17128EPD8I from AMD is a 128K-bit serial configuration PROM designed for Xilinx FPGA initialization, featuring 5V supply voltage, 150 ns access time, industrial temperature range (–40°C to +85°C), and PDIP-8 package. It stores bitstream data to configure Spartan, Virtex, and Artix FPGAs during power-up.
For engineers reviewing the XC17128EPD8I datasheet, pinout, applications, or equivalent options, key selection factors include VCC compatibility with legacy 5V FPGA systems, read timing compliance with Xilinx configuration controllers, and PDIP-8 footprint suitability for prototyping and repair scenarios.
Technical Context
This PROM operates in master serial mode, interfacing directly with Xilinx FPGAs via dedicated configuration pins (DIN, CCLK, INIT_B, PROGRAM_B). Its internal architecture supports sequential readout of stored bitstream without external address decoding.
It uses NMOS technology with TTL-compatible I/O, requires no external clock for read operation, and relies on FPGA-generated CCLK for synchronous data transfer during configuration. The device asserts INIT_B low upon power-up to signal readiness for programming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 128 Kbit (16 K × 8) - provides full bitstream storage for mid-complexity Xilinx FPGAs like XC3S200 or XC2VP4. |
| Supply Voltage | 5.0 V ±10% - matches legacy 5V FPGA configuration voltage rails; not compatible with 3.3V-only systems. |
| Access Time | 150 ns - ensures timing margin meets Xilinx Spartan-II/III master serial configuration requirements. |
| Operating Temp | –40°C to +85°C - qualified for industrial environments including factory automation and test equipment. |
| Package | PDIP-8 - through-hole mounting enables hand-soldering, board rework, and socket-based FPGA development. |
| Interface | Serial Master Mode - connects directly to FPGA configuration pins without external logic or level shifters. |
Pinout & Package
XC17128EPD8I is housed in an 8-pin plastic dual in-line package (PDIP) with 0.3-inch body width and standard 0.1-inch pin spacing. Pin functions are electrically and physically defined per Xilinx XCN001 and AMD XC1700 series documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power Supply | 5V main supply input; must be decoupled locally with 0.1 µF ceramic capacitor. |
| GND | Ground Reference | Signal and power ground return path; connected to system ground plane. |
| DIN | Serial Data Input | Configures PROM during programming; driven by FPGA or external programmer. |
| CCLK | Configuration Clock | Input clock from FPGA controlling synchronous serial readout timing. |
| INIT_B | Initialization Status | Open-drain output signaling PROM readiness or error during power-up or reconfiguration. |
| PROGRAM_B | Program Control | Active-low input initiating erase-and-program cycle when pulled low. |
| CE_B | Chip Enable | Active-low enable controlling read access; tied high for default FPGA configuration use. |
| OE_B | Output Enable | Active-low control for DIN/CCLK/INIT_B tri-state behavior; typically tied high. |
Key Features
| Feature | Design Value |
|---|---|
| Single 5V Supply Operation | Eliminates need for dual-voltage regulators in legacy FPGA designs using 5V configuration rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration PROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCF01SVO20C | 3.3V-only supply, 20-pin TSSOP, 1 Mbit capacity, JTAG-compatible interface. | Designed for newer Xilinx FPGAs with 3.3V configuration rails and boundary-scan programming support. | Select only if migrating to 3.3V systems and requiring larger bitstream storage or JTAG in-system programming. |
| AT17LV010-10JU | 3.3V/5V dual-supply capable, 1 Mbit, 44-pin PLCC, 10 ns access time. | Higher density and faster timing; PLCC package requires surface-mount assembly and reflow. | Choose when higher capacity or speed is required and PLCC footprint is acceptable for production design. |
Compared with XC17128EPD8I, XCF01SVO20C requires voltage redesign and lacks PDIP-8 serviceability, while AT17LV010-10JU offers greater density but sacrifices through-hole repairability and legacy 5V simplicity.

FAQ
Is XC17128EPD8I compatible with Xilinx Spartan-3 FPGAs?
Yes, XC17128EPD8I is fully compatible with Spartan-3 FPGAs in master serial configuration mode. Its 128 Kbit capacity supports bitstreams for devices up to XC3S200, and its 5V operation and 150 ns access time meet Xilinx's timing specifications for that family's configuration controller interface.
What is the programming method for XC17128EPD8I?
XC17128EPD8I is programmed via its DIN pin using a serial data stream synchronized to CCLK, typically initiated by pulling PROGRAM_B low. Programming requires a compatible PROM programmer such as the Xilinx Parallel Cable III or third-party tools supporting AMD XC17xx protocols.
Does XC17128EPD8I support JTAG configuration?
No, XC17128EPD8I does not support JTAG configuration. It operates exclusively in master serial mode using DIN, CCLK, INIT_B, and PROGRAM_B signals. JTAG programming is supported only by later XCFxxx-series PROMs, not the XC17xxx family including XC17128EPD8I.
Can XC17128EPD8I be used in a 3.3V system?
No, XC17128EPD8I requires a nominal 5V supply (4.5V–5.5V) and is not rated for 3.3V operation. Using it in a 3.3V system risks failure to initialize or unreliable readout; it is intended for legacy 5V FPGA configuration rails only.
What is the endurance and data retention of XC17128EPD8I?
XC17128EPD8I guarantees 10,000 program/erase cycles and 20-year data retention at +85°C, per AMD's published specifications for the XC1700 series. These values are measured under standard industrial operating conditions and apply to the XC17128EPD8I device specifically.
