Product details
Overview
XC17S20PD8C from AMD is a serial PROM configuration memory device for Spartan-2 FPGAs, providing 2 Mbit storage capacity in an 8-pin DIP package with 5 V supply voltage and 15 ns access time. It stores FPGA bitstreams and supports master serial configuration mode.
For engineers reviewing the XC17S20PD8C datasheet, pinout, applications, or equivalent options, key selection criteria include voltage compatibility with Spartan-2 I/O banks, read timing alignment with FPGA configuration clocks, and through-hole mounting suitability for legacy prototyping and industrial control boards.
Technical Context
This device implements a synchronous serial interface compatible with Xilinx Spartan-2 FPGA configuration controllers, using a single data line (DATA) and clock (CLK) for bitstream loading. It operates exclusively at 5 V and requires no external address decoding logic.
Configuration data is accessed sequentially starting from address 0x00000; the device lacks write capability after initial programming and provides no status registers or erase-cycle indicators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 2 Mbit (262,144 × 8) - holds full bitstream for Spartan-2 XC2S20 and smaller devices |
| Supply Voltage | 5.0 V ± 10% - matches Spartan-2 core and I/O bank voltage requirements |
| Access Time | 15 ns - meets minimum CLK-to-DATA setup timing for Spartan-2 master serial mode |
| Package | 8-pin plastic DIP (0.300" width) - supports through-hole PCB assembly and socket-based reprogramming |
| Interface | Serial synchronous (CLK + DATA) - eliminates parallel bus routing and reduces FPGA pin count usage |
| Programming Method | One-time programmable (OTP) via standard PROM programmer - no in-system reprogrammability |
Pinout & Package
8-pin plastic dual in-line package (DIP), 0.300" body width, 0.100" pin pitch, through-hole mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply | 5 V input for internal logic and output drivers; must be decoupled near device |
| GND | Ground reference | Common return path for all signals and power; connects to system ground plane |
| DATA | Serial data output | Active-high, open-drain output delivering configuration bits LSB-first to FPGA DIN pin |
| CLK | Configuration clock input | Accepts 0–25 MHz square wave from FPGA; rising edge triggers DATA output |
| CE# | Chip enable (active low) | Must be held low during configuration; high disables DATA output and reduces standby current |
| PGM# | Program enable (active low) | Used only during programming; tied high during normal operation |
| NC | No connect | Pin 7 is unconnected internally; must remain floating or grounded per layout guidelines |
| NC | No connect | Pin 8 is unconnected internally; no external connection required |
Key Features
| Feature | Design Value |
|---|---|
| Master serial interface support | Directly interfaces with Spartan-2 FPGA CONFIG_MODE = 0 without level shifters or glue logic |
| 5 V-only operation | Eliminates need for dual-supply design or voltage translation when used with 5 V Spartan-2 systems |
| 15 ns access time | Enables reliable configuration at up to 25 MHz clock rate, matching Spartan-2 maximum spec |
| Through-hole DIP packaging | Allows manual rework, socket-based field updates, and compatibility with legacy test fixtures |
| OTP architecture | Prevents accidental overwrite during power cycling or system reset, ensuring bitstream integrity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCF02SVO20C | 2 Mbit, 3.3 V supply, 15 ns access, 20-pin TSSOP - requires voltage translation for 5 V Spartan-2 systems | Designed for Spartan-3 and later; lacks native 5 V I/O compatibility | Select only if migrating to 3.3 V FPGA platforms or adding level-shifting circuitry |
| AT17LV002-10JU | 2 Mbit, 3.3 V/2.5 V dual-supply, 10 ns access, 20-pin SOIC - supports faster clock rates but incompatible voltage domain | Targeted at Virtex-II and CoolRunner-II; no guaranteed timing match with Spartan-2 master serial controller | Use only after verifying CLK-to-DATA timing margin with actual FPGA silicon at target frequency |
Compared with XC17S20PD8C, XCF02SVO20C and AT17LV002-10JU offer higher speed or newer process nodes but require board-level voltage adaptation and lack guaranteed timing alignment with Spartan-2 configuration controllers - making XC17S20PD8C the only drop-in replacement for legacy 5 V systems.

FAQ
Is XC17S20PD8C compatible with Spartan-3 FPGAs?
No, XC17S20PD8C is not compatible with Spartan-3 FPGAs. It is specifically designed for Spartan-2 devices and uses a master serial protocol timing profile validated only for XC2S15, XC2S20, XC2S30, and XC2S50. Spartan-3 requires XCFxx series PROMs with different command sets and voltage thresholds.
What is the maximum clock frequency supported by XC17S20PD8C during configuration?
XC17S20PD8C supports configuration clock frequencies up to 25 MHz, based on its 15 ns access time and Spartan-2 FPGA timing specifications. Operation above this frequency risks DATA setup violations and incomplete bitstream loading, which may result in FPGA configuration failure or undefined logic states.
Can XC17S20PD8C be reprogrammed in-circuit?
No, XC17S20PD8C cannot be reprogrammed in-circuit. It is a one-time programmable (OTP) device requiring external PROM programming equipment. The PGM# pin is used only during factory programming; no in-system programming interface or erase functionality exists in XC17S20PD8C.
Does XC17S20PD8C require external pull-up resistors on DATA or CLK lines?
XC17S20PD8C requires a 4.7 kΩ pull-up resistor on the DATA line to ensure valid high-level signaling when the output is in high-impedance state. The CLK line does not require a pull-up; it is driven actively by the FPGA's configuration controller and must meet TTL-compatible voltage thresholds.
What is the operating temperature range for XC17S20PD8C?
XC17S20PD8C is rated for commercial temperature operation from 0 °C to +70 °C. It is not specified for extended or industrial temperature ranges; use in environments exceeding 70 °C requires derating analysis and thermal validation of timing margins and data retention.
