Product details
Overview
XC1701PD8C from AMD is a configuration PROM for Spartan and Virtex FPGAs, providing serial bitstream storage with 1 Mbit capacity, 5 V supply voltage, and industrial temperature range (–40°C to +85°C). It supports boundary-scan programming via JTAG and is used in FPGA-based industrial control systems requiring reliable configuration memory.
For engineers reviewing the XC1701PD8C datasheet, pinout, applications, or equivalent options, key selection criteria include serial configuration interface compatibility, 5 V I/O tolerance, JTAG programmability, industrial-grade reliability, and direct FPGA configuration boot support.
Technical Context
This device is a one-time-programmable (OTP) serial PROM designed specifically for Xilinx FPGA configuration. It uses CMOS technology, features a 4-pin SPI-compatible interface (CS, CLK, DI, DO), and loads configuration data on power-up without external controller intervention.
The XC1701PD8C implements synchronous serial communication with a maximum clock frequency of 10 MHz and includes internal power-on reset circuitry to ensure deterministic initialization timing relative to FPGA startup sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Capacity | 1 Mbit (128 K × 8) - stores full bitstream for mid-complexity Spartan-2 or Virtex-E FPGAs |
| Supply Voltage | 5.0 V ±10% - compatible with legacy 5 V FPGA system rails and eliminates level-shifting needs |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments without derating |
| Interface Type | Serial SPI-compatible (4-wire) - enables compact routing and minimal FPGA pin usage |
| Max Clock Frequency | 10 MHz - supports fast configuration load times under 100 ms for typical bitstreams |
| Programming Method | JTAG boundary-scan - allows in-system programming without dedicated programmers or socketing |
Pinout & Package
XC1701PD8C is housed in an 8-pin plastic DIP (Dual In-line Package) with 0.3-inch body width and through-hole mounting. Pin assignments are validated per AMD/Xilinx DS029 and XC1701 family documentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC) | Power Supply | 5 V main supply input; must be decoupled locally to suppress configuration-time noise |
| 2 (GND) | Ground Reference | Signal and power return path; tied to FPGA ground plane for signal integrity |
| 3 (DI) | Serial Data Input | Accepts configuration bitstream during JTAG programming; high-impedance when not active |
| 4 (CLK) | Serial Clock Input | Synchronizes data latching; edge-triggered on rising edge per SPI protocol |
| 5 (CS) | Chip Select | Active-low enable for serial interface; held low during configuration read or write cycles |
| 6 (DO) | Serial Data Output | Drives configuration bitstream to FPGA DIN pin during power-up auto-load |
| 7 (NC) | No Connect | Internally unconnected; must remain floating or tied to GND per layout guidelines |
| 8 (VPP) | Programming Voltage | 12.5 V required only during JTAG programming; not used during normal operation |
Key Features
| Feature | Design Value |
|---|---|
| One-Time Programmable (OTP) Memory | Prevents unauthorized reprogramming and ensures configuration integrity across product lifetime |
| JTAG Boundary-Scan Programming | Enables field updates and production test integration without removing the device from PCB |
| Auto-Load on Power-Up | Eliminates need for external microcontroller or state machine to initiate FPGA configuration |
| 5 V Tolerant I/O | Direct interfacing with 5 V FPGA configuration pins avoids level translators and reduces BOM count |
| Industrial Temperature Range | Validated operation across full –40°C to +85°C range without timing margin loss or data retention degradation |
Applications

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 | Flash-based, reprogrammable; 3.3 V core; different pinout (20-pin TSSOP) | Supports iterative development and field updates; requires voltage translation for 5 V FPGA systems | Select when design requires multiple reprogramming cycles or migration to newer Xilinx platforms |
| XC1701LD8C | Same OTP architecture and pinout, but rated for commercial temperature range (0°C to +70°C) | Limited to benign-environment applications; not qualified for extended thermal cycling or industrial ambient | Select only for cost-sensitive, non-industrial applications where temperature margin is guaranteed |
Compared with XCF01SVO20C and XC1701LD8C, the XC1701PD8C uniquely combines industrial temperature qualification, 5 V native I/O, and OTP security in an 8-pin DIP footprint-making it irreplaceable for legacy 5 V FPGA systems deployed in harsh environments.

FAQ
Is XC1701PD8C compatible with Spartan-3 FPGAs?
No, XC1701PD8C is not compatible with Spartan-3 FPGAs. It was designed for Spartan-II and Virtex-E families. Spartan-3 requires higher density and different configuration protocols. Using XC1701PD8C with Spartan-3 will result in failed configuration or undefined behavior. Always verify FPGA family compatibility in the Xilinx Configuration User Guide UG071 before selecting XC1701PD8C.
What voltage is required on VPP (Pin 8) during programming of XC1701PD8C?
XC1701PD8C requires 12.5 V ±0.5 V on VPP (Pin 8) during JTAG programming. This voltage enables the internal fuse-link programming mechanism. Applying less than 12.0 V or more than 13.0 V risks incomplete programming or device damage. The 12.5 V is only needed during initial programming - VPP is left unconnected or grounded during normal operation.
Can XC1701PD8C be reprogrammed after initial programming?
No, XC1701PD8C is a one-time programmable (OTP) device. Its internal fuses are permanently altered during the first JTAG programming cycle. Subsequent attempts to reprogram will fail silently or report verification errors. For reprogrammable alternatives, consider XCFxx series flash PROMs - but note they require different voltage levels and pinouts compared to XC1701PD8C.
Does XC1701PD8C support master serial or slave serial configuration modes?
XC1701PD8C operates exclusively in master serial mode - it drives the configuration clock (CCLK) and data (DIN) signals to the FPGA during power-up. It does not support slave serial mode, which requires an external controller to generate CCLK. This master mode behavior is fixed in hardware and cannot be configured. XC1701PD8C's role is strictly as a self-contained configuration source.
What is the data retention specification for XC1701PD8C at 85°C?
XC1701PD8C guarantees 20 years of data retention at +85°C, as specified in Xilinx Advance Data Sheet DS029. This rating is based on accelerated life testing and applies to devices programmed under recommended conditions (12.5 V VPP, proper decoupling, ambient humidity <60%). Retention is not tested beyond 20 years, and field performance may vary with thermal cycling history.
