Product details
Overview
XC17128EPD8C from AMD is a 128K-bit serial PROM configured for Xilinx FPGA configuration, operating at 5V supply voltage with 150 ns access time and industrial temperature range (–40°C to +85°C), used in embedded reconfiguration of Spartan and Virtex family FPGAs.
For engineers reviewing the XC17128EPD8C datasheet, pinout, applications, or equivalent options, key selection criteria include VCC compatibility, read access timing, serial interface protocol, and JEDEC-standard SOIC-8 package footprint.
Technical Context
This device implements a synchronous serial interface compliant with Xilinx configuration protocol, supporting master serial mode for FPGA bitstream loading. It uses NMOS technology with TTL-compatible inputs and outputs, and includes internal address counter for sequential read operation.
XC17128EPD8C features no internal write logic - it is factory-programmed and read-only. Data retention exceeds 20 years at 85°C, and it supports single-supply 5V operation without external level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 128 Kbit (16 K × 8) - provides full configuration bitstream storage for mid-complexity Xilinx FPGAs like XC4000E/XC4000X series. |
| Supply Voltage | 5.0 V ±10% - compatible with legacy 5V FPGA configuration power rails and eliminates need for voltage translators. |
| Access Time | 150 ns max - ensures reliable timing margin for FPGA configuration clock rates up to 6.67 MHz. |
| Operating Temp | –40°C to +85°C - qualified for industrial-grade embedded systems requiring extended thermal stability. |
| Package | SOIC-8 (300 mil) - JEDEC MS-012 standard footprint, compatible with automated PCB assembly and legacy board layouts. |
| Interface | Serial synchronous (CLK/DATA) - matches Xilinx Master Serial configuration mode, requiring only two FPGA I/O pins. |
Pinout & Package
XC17128EPD8C is housed in an 8-pin plastic small-outline integrated circuit (SOIC-8) package with 300-mil body width and standard gull-wing lead form.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | Address Input | Not connected internally; pin is no-connect per datasheet - must be left unconnected or tied to GND. |
| CLK | Serial Clock Input | Edge-triggered input synchronizing data output; driven by FPGA configuration controller. |
| DOUT | Data Output | CMOS-level serial data stream delivering configuration bits LSB-first to FPGA DIN pin. |
| VCC | Power Supply | +5V supply pin; requires local 0.1 µF ceramic decoupling capacitor near the package. |
| GND | Ground Reference | System ground return path; must be low-impedance connection shared with FPGA configuration circuitry. |
| CE | Chip Enable Input | Active-low enable; held low during configuration; high state disables output and reduces standby current. |
| OE | Output Enable Input | Active-low control; must be low to enable DOUT driver; tied low permanently in most designs. |
| NC | No Connect | Pin 1 is not bonded; must remain unconnected - no pull-up/down or routing required. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-programmed memory | Eliminates field programming risk and ensures bitstream integrity across production batches. |
| TTL-compatible I/O | Direct interface with 5V FPGA configuration pins without level-shifting components or design overhead. |
| Single 5V supply | Reduces BOM count and simplifies power architecture versus multi-voltage PROM solutions. |
| Industrial temperature rating | Enables deployment in harsh environments such as factory automation controllers and outdoor telecom equipment. |
| JEDEC SOIC-8 footprint | Supports drop-in replacement of legacy configuration PROMs and leverages existing PCB tooling and assembly processes. |

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 | 1 Mbit capacity, 3.3V supply, VQFP-20 package - higher density but incompatible voltage and footprint. | Targets newer 3.3V Xilinx FPGAs (Spartan-3, Virtex-II); not suitable for legacy 5V systems. | Select only when migrating to 3.3V FPGA families and redesigning PCB layout. |
| AT17LV010-10PU | 1 Mbit, 3.3V/2.5V dual-supply, PDIP-20 package - wider voltage range but larger package and different pinout. | Used in mixed-voltage prototyping boards; lacks industrial temp rating and SOIC-8 compatibility. | Prefer for lab validation; avoid for volume industrial deployments requiring SOIC-8 footprint and –40°C operation. |
Compared with XCF01SVO20C and AT17LV010-10PU, XC17128EPD8C offers guaranteed 5V operation, SOIC-8 mechanical compatibility, and industrial temperature support - making it the only option for maintaining legacy FPGA configuration infrastructure without PCB revision.

FAQ
Is XC17128EPD8C still in production or considered obsolete?
XC17128EPD8C is listed as active and available through authorized distributors and Aetrix Electronics. While newer FPGA families use different configuration schemes, this part remains supported for legacy system maintenance and repair. No obsolescence notice has been issued by AMD/Xilinx for XC17128EPD8C.
Can XC17128EPD8C be reprogrammed in-system?
No, XC17128EPD8C is a one-time-programmable (OTP) PROM manufactured with factory-programmed data. It contains no internal write circuitry or erase capability. Reprogramming requires physical replacement with a newly programmed unit. XC17128EPD8C is strictly read-only during operation.
What FPGA families are explicitly supported by XC17128EPD8C?
XC17128EPD8C is documented for use with Xilinx XC4000E, XC4000EX, XC4000XL, and Spartan-XL FPGA families. Its timing and interface match the Master Serial configuration mode specified in Xilinx Application Note XAPP058 for those devices.
Does XC17128EPD8C require external pull-up resistors on any pins?
No external pull-ups are required. CE and OE are active-low inputs and must be held low during configuration; they are typically hard-wired to GND. CLK and DOUT have no pull requirements per the datasheet. XC17128EPD8C drives all outputs actively and does not rely on external termination.
How is data integrity verified during XC17128EPD8C read operations?
Data integrity relies on manufacturing test and long-term retention qualification - XC17128EPD8C has no built-in CRC, parity, or error-checking circuitry. Verification occurs externally via FPGA configuration controller logic that monitors INIT_B and DONE signals and retries on failure. XC17128EPD8C itself performs no internal validation.
