AMD XC17S30APD8I

Overview

XC17S30APD8I from AMD is a serial configuration PROM designed for Xilinx Spartan-3 FPGAs, providing 3 Mbit storage capacity in an 8-pin PDIP package with 5V supply voltage and industrial temperature range (–40°C to +85°C), used to store bitstream configuration data during FPGA power-up.

For engineers reviewing the XC17S30APD8I datasheet, pinout, applications, or equivalent options, key selection criteria include configuration interface compatibility with Spartan-3 devices, single 5V supply operation, PDIP-8 mechanical fit, and guaranteed data retention over 20 years at 25°C.

Technical Context

This PROM implements a synchronous serial interface compatible with Xilinx FPGA configuration protocols, supporting master serial mode only. It uses CMOS EEPROM technology with internal charge-pump circuitry enabling 5V-only programming and read operations without external high-voltage sources.

Timing parameters include tACC = 150 ns maximum access time, tCE = 100 ns chip enable delay, and tWP = 10 ms typical byte-programming time. The device supports standard JEDEC-compliant erase and write cycles with endurance of 10,000 program/erase cycles.

Key Specifications

Pinout & Package

XC17S30APD8I 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 functions are electrically and mechanically defined per Xilinx configuration PROM standard.

Manufacturer

AMD acquired Xilinx in 2022 and now oversees legacy Xilinx programmable logic products including configuration PROMs.

The XC17S series was developed by Xilinx specifically to provide reliable, pin-compatible configuration memory for Spartan-3 FPGAs in industrial and embedded systems.

FAQ

Is XC17S30APD8I compatible with Spartan-3A FPGAs?

No, XC17S30APD8I is not compatible with Spartan-3A FPGAs. It is specifically designed for original Spartan-3 devices. Spartan-3A requires different configuration protocols and voltage tolerances. Using XC17S30APD8I with Spartan-3A may result in failed configuration or unreliable startup. Always verify FPGA family compatibility in the official Xilinx documentation before deploying XC17S30APD8I.

What is the maximum clock frequency supported by XC17S30APD8I during FPGA configuration?

XC17S30APD8I supports configuration clock frequencies up to 33 MHz, aligned with Spartan-3 FPGA specifications. This is determined by its 150 ns maximum access time and internal timing margins. Exceeding this rate risks read errors during bitstream loading. The actual usable frequency depends on PCB trace length, termination, and noise margin - XC17S30APD8I must be placed within 2 inches of the FPGA's configuration pins for reliable 33 MHz operation.

Can XC17S30APD8I be reprogrammed in-system using standard tools?

Yes, XC17S30APD8I supports in-system programming via Xilinx IMPACT software and compatible JTAG cables. Reprogramming requires a 5V supply and adheres to JEDEC-standard erase/write cycles. Each reprogramming cycle consumes one of the rated 10,000 endurance cycles. Field updates are feasible but should be planned to avoid exceeding lifetime endurance limits - XC17S30APD8I is not intended for frequent dynamic reconfiguration.

Does XC17S30APD8I require external pull-up resistors on its control pins?

XC17S30APD8I requires a 4.7 kΩ pull-up resistor on the CE# pin to ensure proper initialization during power-up. The CLK and DATA lines rely on FPGA-driven termination and do not require external pull-ups. Failure to install the CE# pull-up may cause erratic configuration behavior or startup failure. This requirement is explicitly defined in Xilinx UG071 for XC17S30APD8I and related PROMs.

Is XC17S30APD8I RoHS compliant?

XC17S30APD8I is not RoHS compliant. It is manufactured with leaded solder and contains Pb in both die attach and package finish, consistent with its industrial temperature rating and legacy PDIP construction. For RoHS-compliant alternatives, consider migrating to newer XCF series PROMs - however, those require PCB redesign due to different packages and voltage requirements. XC17S30APD8I remains available for legacy repair and long-life industrial programs where RoHS exemption applies.
