AMD XC17S200APDG8I

Overview

XC17S200APDG8I from AMD (formerly Xilinx) is a serial configuration PROM designed to store and load configuration bitstreams for Spartan-2 FPGAs. It provides 200 kbit of OTP memory, supports 3.3 V operation, and features a 5 MHz serial interface with industrial temperature range (–40°C to +85°C). It is used in FPGA-based industrial control logic systems requiring nonvolatile, single-chip configuration storage.

For engineers reviewing the XC17S200APDG8I datasheet, pinout, applications, or equivalent options, key selection criteria include OTP memory size, 3.3 V supply compatibility, serial clock frequency limit, industrial temperature rating, and FPGA configuration protocol alignment with Spartan-2 devices.

Technical Context

This PROM implements a synchronous serial interface compliant with Xilinx Spartan-2 FPGA configuration requirements. It uses CMOS OTP technology and requires no external programming voltage - programming is performed via standard 3.3 V I/O signals using the Xilinx BitGen tool and compatible programmers.

The device operates exclusively in master serial mode, delivering configuration data on the DIN line to the FPGA's INIT pin during power-up or PROG_B assertion. Timing parameters including tSU (data setup), tH (data hold), and tCYC (clock cycle) are specified at 5 MHz maximum clock rate and –40°C to +85°C ambient.

Compared with XC17S200APDG8I, XC17S200AIPD8 sacrifices industrial temperature tolerance for lower cost, while XC17S100APDG8I reduces memory capacity by 50% but retains full thermal compliance - both require explicit bitstream size and ambient validation before substitution.

Availability

XC17S200APDG8I is available at Aetrix Electronics and suitable for industrial PLCs, motor drive control units, and automated test equipment requiring stable component supply across extended product lifecycles.

Supply support for XC17S200APDG8I 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, inheriting its FPGA and configuration PROM portfolio. Xilinx originally developed these PROMs specifically for seamless integration with its Spartan family FPGAs.

The XC17SxxxA series was engineered to provide robust, single-chip configuration solutions for Spartan-2 FPGA deployments in harsh industrial settings - prioritizing reliability, simplicity, and protocol fidelity over programmability flexibility.

FAQ

What is the programming method supported by XC17S200APDG8I?

XC17S200APDG8I supports in-system programming via JTAG boundary-scan or dedicated PROM programmers such as the Xilinx Parallel Cable III. Programming occurs at 3.3 V with no external high-voltage supply needed. The XC17S200APDG8I is one-time programmable - once written, the bitstream cannot be erased or rewritten, ensuring configuration integrity in deployed systems.

Does XC17S200APDG8I support hot-swapping or dynamic reconfiguration?

No, XC17S200APDG8I does not support hot-swapping or dynamic reconfiguration. It is a static, one-time programmable device intended solely for power-on FPGA configuration loading. The XC17S200APDG8I lacks runtime reprogramming capability and must be pre-programmed before installation. Dynamic partial reconfiguration requires external microcontroller-based loaders or newer FPGA-integrated configuration schemes.

Can XC17S200APDG8I be used with Spartan-3 or later Xilinx FPGAs?

No, XC17S200APDG8I is not compatible with Spartan-3 or later FPGAs. Its timing, command set, and bitstream format are specific to Spartan-2 devices. Using XC17S200APDG8I with Spartan-3 or Virtex families will result in failed configuration. The XC17S200APDG8I must be paired only with Spartan-2 FPGAs such as XC2S50 through XC2S200.

What is the role of the PROG pin on XC17S200APDG8I?

The PROG pin on XC17S200APDG8I initiates in-system programming when driven high. It resets internal address counters and enables the DIN input path. During normal operation, PROG must remain low. The XC17S200APDG8I requires a clean, slew-rate-controlled PROG signal to prevent spurious programming - typical designs use RC filtering or FPGA GPIO with debouncing logic before driving this pin.

Is external pull-up required on the DOUT pin of XC17S200APDG8I?

Yes, XC17S200APDG8I features an open-drain DOUT output that requires an external 4.7 kΩ pull-up resistor to 3.3 V. Without this pull-up, the FPGA's DIN input will float during configuration, causing unpredictable startup behavior or configuration failure. This requirement is explicitly defined in the XC17S200APDG8I datasheet and applies regardless of PCB layout or trace length.
