AMD XC17S150APD8I

Overview

XC17S150APD8I from AMD (formerly Xilinx) is a serial PROM device designed to configure Spartan-3 FPGAs. It provides 150 kbit of configuration memory, operates at 3.3 V supply voltage, supports serial configuration interface, and features industrial temperature range (–40°C to +85°C). It is used in embedded control systems requiring reliable FPGA reconfiguration.

For engineers reviewing the XC17S150APD8I datasheet, pinout, applications, or equivalent options, key selection factors include configuration bitstream capacity, VCC tolerance, serial interface timing compliance with Spartan-3 startup requirements, and industrial-grade reliability for field-deployed logic systems.

Technical Context

The XC17S150APD8I implements a synchronous serial interface compatible with Xilinx Spartan-3 FPGA configuration protocols. It uses CMOS EEPROM technology with built-in charge pump for programming, and supports both master and slave serial configuration modes.

It requires no external high-voltage programming supply and retains configuration data for 20 years with 10,000 write/erase cycles. The device is accessed via dedicated CONFIG_IN and CONFIG_OUT pins aligned to Spartan-3's INIT_B and CCLK timing constraints.

Key Specifications

Pinout & Package

Compared with XCF01SVO20C and XC17S150AIPD8, the XC17S150APD8I uniquely satisfies legacy Spartan-3 industrial deployments requiring 3.3 V operation, PDIP-8 footprint, and –40°C to +85°C qualification - no other single-package alternative meets all three constraints.

Availability

XC17S150APD8I is available at Aetrix Electronics and suitable for industrial motor control, programmable logic controllers (PLCs), and telecom line card applications requiring stable component supply across extended product lifecycles.

Supply support for XC17S150APD8I includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

AMD acquired Xilinx in 2022 and maintains legacy configuration PROM product lines for backward compatibility and long-life support.

The XC17S family was developed specifically to provide standardized, low-cost, serial configuration memory for Spartan-series FPGAs in cost-sensitive industrial and communications applications.

FAQ

What is the primary function of the XC17S150APD8I in a Spartan-3 FPGA system?

The XC17S150APD8I serves as the nonvolatile configuration memory for Spartan-3 FPGAs, storing the bitstream that defines the FPGA's logic functionality at power-up. It loads this data synchronously via the FPGA's configuration interface, enabling autonomous startup without host processor intervention. The XC17S150APD8I ensures deterministic initialization and eliminates the need for external configuration controllers in standalone FPGA applications.

Can the XC17S150APD8I be reprogrammed in-system, and what are the voltage requirements?

Yes, the XC17S150APD8I supports in-system programming using standard 3.3 V supply - no external high-voltage generator is needed due to its integrated charge pump. Reprogramming is performed through the DIN pin under CCLK control, with WRITE_B held low. The XC17S150APD8I tolerates 3.3 V ±10%, and operation outside this range may cause configuration corruption or write failure.

Is the XC17S150APD8I pin-compatible with other members of the XC17S family?

Yes, all XC17SxxxAPD8I variants (e.g., XC17S100APD8I, XC17S200APD8I) share identical PDIP-8 pinout and interface signaling. Differences are limited to memory size and internal array organization; the XC17S150APD8I can replace smaller variants without layout changes, provided the bitstream fits within its 150 kbit capacity.

Does the XC17S150APD8I support daisy-chain configuration with multiple FPGAs?

No, the XC17S150APD8I does not support native daisy-chaining. It is designed for point-to-point configuration of a single Spartan-3 FPGA. For multi-FPGA systems, each device requires its own XC17S150APD8I or a centralized configuration controller; the XC17S150APD8I lacks the DOUT-to-DIN pass-through logic required for serial chaining.

What is the significance of the 'I' suffix in XC17S150APD8I?

The 'I' suffix in XC17S150APD8I denotes industrial temperature grade (–40°C to +85°C), distinguishing it from commercial-grade versions like XC17S150APD8C (0°C to +70°C). This rating certifies the XC17S150APD8I for use in harsh environments such as factory floors, outdoor base stations, and transportation systems where thermal stability is critical.
