Product details
Overview
XC17S40XLPD8C from AMD (formerly Xilinx) is a serial configuration PROM designed to store and load bitstreams into Spartan-XL FPGAs. It provides 4 Mbit capacity, operates at 5.0 V supply, supports 10 MHz read speed, and uses an 8-pin PDIP package. It is used in legacy industrial control systems requiring nonvolatile FPGA configuration storage.
For engineers reviewing the XC17S40XLPD8C datasheet, pinout, applications, or equivalent options, key selection factors include voltage compatibility with Spartan-XL devices, serial configuration interface timing, PDIP-8 mechanical fit, and end-of-life supply continuity for repair and replacement.
Technical Context
The XC17S40XLPD8C implements a synchronous serial interface compliant with Xilinx's proprietary configuration protocol for Spartan-XL family FPGAs. It features internal address auto-increment and supports both power-up and in-system reconfiguration modes.
It requires no external clock source during configuration loading and delivers data on the rising edge of the CCLK signal generated by the target FPGA. Its 5.0 V operation matches the core and I/O voltage requirements of Spartan-XL devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Capacity | 4 Mbit (512 K × 8) - stores full bitstream for Spartan-XL devices up to XC17S40 size |
| Supply Voltage | 5.0 V ±10% - matches Spartan-XL FPGA VCCIO and VCCINT rail requirements |
| Max Read Speed | 10 MHz - supports minimum CCLK frequency for reliable bitstream loading |
| Interface Type | Synchronous serial (DIN, DOUT, CCLK, CE#, RESET#) - direct connection to FPGA configuration pins |
| Package | 8-pin PDIP - through-hole mounting compatible with legacy PCBs and manual rework |
| Endurance | 10,000 write/erase cycles - sufficient for factory programming and limited field updates |
| Data Retention | 20 years at 25°C - ensures long-term reliability in unpowered storage |
Pinout & Package
XC17S40XLPD8C is housed in an 8-pin plastic dual in-line package (PDIP) with 0.3-inch body width and 0.1-inch pin pitch. Pin numbering follows standard PDIP convention, with Pin 1 marked by dot or notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (CE#) | Chip Enable | Active-low enable; must be low for read access and bitstream output |
| Pin 2 (DIN) | Data Input | Serial input for programming; not used during FPGA configuration mode |
| Pin 3 (DOUT) | Data Output | Serial output carrying configuration data to FPGA DIN pin |
| Pin 4 (GND) | Ground | Reference return path for all digital signals and power |
| Pin 5 (CCLK) | Configuration Clock | Input clock synchronized to FPGA CCLK; controls data timing |
| Pin 6 (VCC) | Power Supply | +5.0 V supply for internal logic and output drivers |
| Pin 7 (RESET#) | Reset Input | Active-low asynchronous reset; clears internal address counter |
| Pin 8 (NC) | No Connect | Internally unconnected; must remain floating or tied to GND per design guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Single 5.0 V supply operation | Eliminates need for dual-voltage regulation in Spartan-XL systems |
| Auto-increment addressing | Reduces FPGA control overhead during sequential bitstream reads |
| Hardware reset capability | Enables deterministic reinitialization without power cycle |
| Industrial temperature range support | Rated for –40°C to +85°C operation in embedded control environments |
| JEDEC-standard PDIP-8 footprint | Enables drop-in replacement and compatibility with existing wave-solder 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 |
|---|---|---|---|
| XCF04SVO20C | 4 Mbit, 3.3 V supply, VO20 package - incompatible voltage and package | Requires level-shifting and PCB redesign; intended for Virtex-II systems | Select only if migrating to 3.3 V FPGA platforms with compatible pinout |
| AT17LV040-10PU | 4 Mbit, 3.3 V/2.5 V dual-supply, PDIP-20 - different pin count and interface | Supports JTAG and master-serial modes; not pin-compatible with XC17S40XLPD8C | Consider for new designs needing flexible configuration interfaces and wider voltage support |
Compared with XC17S40XLPD8C, the XCF04SVO20C and AT17LV040-10PU require board-level changes due to voltage mismatch, pin count differences, and protocol divergence-making them alternatives rather than drop-in replacements for legacy Spartan-XL systems.

FAQ
Is XC17S40XLPD8C compatible with Spartan-II or Spartan-III FPGAs?
No. XC17S40XLPD8C is designed exclusively for Spartan-XL FPGAs. Spartan-II and later families use different configuration protocols, voltage levels, and bitstream formats. Using XC17S40XLPD8C with non-Spartan-XL devices will result in failed configuration or undefined behavior.
What programming tools support XC17S40XLPD8C?
XC17S40XLPD8C is programmable using Xilinx Parallel Cable III, Xilinx Impact software (v14.7 and earlier), and third-party PROM programmers that support Xilinx 1700-series serial PROMs with PDIP-8 socket adapters. Programming requires the .bit file generated for the target Spartan-XL device.
Does XC17S40XLPD8C support in-system programming (ISP)?
Yes, XC17S40XLPD8C supports in-system programming via its DIN pin when CE# and RESET# are asserted in the correct sequence. However, ISP requires external control logic or a microcontroller to manage the programming waveform - it is not autonomous like JTAG-based PROMs.
Can XC17S40XLPD8C be used with 3.3 V Spartan-XL variants?
No. XC17S40XLPD8C is specified for 5.0 V operation only. Spartan-XL devices with 3.3 V I/O support still require 5.0 V for configuration PROM interface compatibility. Interfacing XC17S40XLPD8C with a 3.3 V-only system risks overvoltage damage to downstream receivers.
What is the maximum operating temperature rating for XC17S40XLPD8C?
XC17S40XLPD8C is rated for operation from –40°C to +85°C. This industrial temperature range is validated per Xilinx specification DS029 and applies to the PDIP-8 package variant XC17S40XLPD8C under continuous 5.0 V supply and ≤10 MHz CCLK conditions.
