AMD XC2S150-5FGG456I

Overview

XC2S150-5FGG456I from AMD (formerly Xilinx) is a Spartan-II family FPGA with 150,000 system gates, 1728 CLBs, 160 I/O pins, and a 5 ns maximum input-to-output delay. It implements synchronous digital logic in embedded control, industrial interface, and communication protocol bridging applications.

For engineers reviewing the XC2S150-5FGG456I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count, CLB density, speed grade (-5), and FGG456 package compatibility with PCB layout constraints and thermal requirements.

Technical Context

The XC2S150-5FGG456I uses a configurable logic block (CLB) architecture with four-input LUTs and flip-flops per slice, supporting synchronous design with global clock routing and dedicated carry chains. It supports IEEE 1149.1 JTAG boundary-scan testing and in-system configuration via serial PROM or microprocessor interface.

It operates at 3.3 V core and I/O supply, with LVCMOS/LVTTL-compatible I/O standards and programmable slew rate and drive strength per bank. Configuration is SRAM-based and requires external nonvolatile memory for power-up initialization.

Key Specifications

Pinout & Package

XC2S150-5FGG456I is housed in a 456-ball fine-pitch BGA (FGG456) package with 27 × 27 mm body size, 1.0 mm ball pitch, and standard JEDEC MO-251AC footprint. Thermal pad on underside requires solder paste stencil design per Xilinx S001-2 guidelines.

Manufacturer

AMD acquired Xilinx in 2022 and maintains legacy Spartan product support, including documentation, configuration tools, and qualified sources for industrial and aerospace applications.

The Spartan-II family, including XC2S150-5FGG456I, was designed for cost-sensitive, high-volume embedded logic replacement - targeting industrial control, test equipment, and communications infrastructure where gate density and I/O flexibility outweigh advanced features like DSP slices or high-speed transceivers.

FAQ

What is the maximum operating frequency supported by the XC2S150-5FGG456I?

The XC2S150-5FGG456I has a -5 speed grade, guaranteeing a maximum input-to-output delay of 5 ns for critical paths. This supports system clock frequencies up to 125 MHz in well-constrained designs with proper placement and routing. Actual achievable frequency depends on logic depth, I/O timing, and clock network usage - verified per design through Xilinx ISE timing analysis.

Does the XC2S150-5FGG456I require external configuration memory?

Yes, the XC2S150-5FGG456I uses SRAM-based configuration and requires external nonvolatile memory (e.g., XCF02S or compatible serial PROM) to store the bitstream. On power-up, the FPGA loads configuration data automatically via master serial mode unless configured otherwise through mode pins.

Can the XC2S150-5FGG456I operate with mixed I/O voltages?

Yes, the XC2S150-5FGG456I supports four independent I/O banks, each configurable for 3.3 V or 2.5 V VCCO. This enables direct interfacing with devices operating at different logic levels - for example, connecting a 3.3 V microcontroller to a 2.5 V ADC - provided each bank's VCCO and IOSTANDARD are set consistently.

Is the XC2S150-5FGG456I pin-compatible with other Spartan-II devices in the FGG456 package?

No - while multiple Spartan-II devices use the FGG456 package (e.g., XC2S100, XC2S200), pinouts differ significantly due to varying CLB counts, RAM block locations, and dedicated resource assignments. The XC2S150-5FGG456I has a unique pin map defined in Xilinx DS001 v2.5 and is not interchangeable without PCB redesign.

What development tools support the XC2S150-5FGG456I?

The XC2S150-5FGG456I is fully supported by Xilinx ISE Design Suite 14.7, including synthesis, place-and-route, and bitstream generation. Programming is performed via iMPACT or third-party JTAG adapters. AMD continues to host legacy documentation and software downloads for Spartan-II devices under the Xilinx archive portal.
