AMD XC2S150-5FG256C

Overview

XC2S150-5FG256C from AMD (formerly Xilinx) is a Spartan-II family FPGA with 150,000 system gates, 1728 logic cells, and a 5 ns maximum input-to-output delay. It features 224 I/O pins in a 256-pin Fine-Pitch Ball Grid Array (FBGA) package and operates at 3.3 V supply voltage. It is used in industrial control logic, digital signal preprocessing, and reconfigurable peripheral interface design.

For engineers reviewing the XC2S150-5FG256C datasheet, pinout, applications, or equivalent options, key selection considerations include logic density, I/O count, speed grade (-5), FBGA256 thermal and routing constraints, and legacy Spartan-II configuration compatibility.

Technical Context

The XC2S150-5FG256C implements configurable logic blocks (CLBs) with four-input LUTs and flip-flops, distributed RAM, and dedicated carry logic for arithmetic functions. It supports SelectI/O standards including LVTTL, LVCMOS, and PCI-compatible signaling on its 224 user I/Os.

Configuration is performed via serial mode using an external PROM or parallel slave mode with a microprocessor. The device includes internal global clock buffers and DLL-based clock management for timing control across the array.

Key Specifications

Pinout & Package

Compared with XC2S150-6FG256C and XC2S100-5FG256C, the XC2S150-5FG256C balances performance, density, and cost for mid-complexity reconfigurable logic-offering full 150K-gate capacity at the standard -5 timing margin without over-spec'ing speed or under-utilizing resources.

Availability

XC2S150-5FG256C is available at Aetrix Electronics and suitable for industrial motion control, digital video interface bridging, and legacy bus extension requiring stable component supply throughout long-life production cycles.

Supply support for XC2S150-5FG256C 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 now oversees the Spartan, Virtex, and Artix FPGA families. Xilinx originally developed the Spartan-II series for cost-sensitive, high-volume logic replacement applications.

The XC2S150-5FG256C belongs to the Spartan-II product line, designed specifically for migration from PALs/CPLDs and ASIC prototyping in industrial and communications equipment where logic density, I/O flexibility, and predictable timing are critical.

FAQ

What is the maximum operating frequency supported by the XC2S150-5FG256C?

The XC2S150-5FG256C has a -5 speed grade specifying a maximum input-to-output delay of 5 ns. This enables reliable operation at system clock frequencies up to 125 MHz for synchronous logic paths. Actual achievable frequency depends on design topology, placement, and routing; timing analysis must be performed using Xilinx ISE tools with the XC2S150-5FG256C device model.

Does the XC2S150-5FG256C support JTAG boundary-scan testing?

Yes, the XC2S150-5FG256C fully complies with IEEE 1149.1 and supports JTAG boundary-scan for board-level testing and in-system programming. Pins TDI, TDO, TMS, and TCK are dedicated for this function, and the XC2S150-5FG256C implements mandatory instruction register and boundary-scan register logic per the standard.

Can the XC2S150-5FG256C be configured using a microprocessor?

Yes, the XC2S150-5FG256C supports parallel slave mode configuration, allowing a host microprocessor to load the configuration bitstream directly via its 8-bit or 16-bit data bus. This requires asserting PROGRAM_B and monitoring DONE, with configuration data written to the XC2S150-5FG256C's data pins under control of the processor's GPIO or memory-mapped interface.

What I/O standards are supported by the XC2S150-5FG256C?

The XC2S150-5FG256C supports LVTTL, LVCMOS (3.3 V and 2.5 V), and PCI-compliant signaling across its 224 user I/Os. Each I/O bank is independently configurable for voltage level and drive strength, but all pins in a given bank must share the same VCCO supply voltage. Differential signaling (e.g., LVDS) is supported only on specific pin pairs.

Is the XC2S150-5FG256C still in active production?

The XC2S150-5FG256C is a mature Spartan-II device discontinued by Xilinx in 2008. AMD maintains legacy support and Aetrix Electronics sources it through authorized channels with traceable, date-code-controlled inventory. Long-term availability is managed via lifecycle coordination, not active wafer fabrication.
