AMD XC2S150-5PQ208C

Overview

XC2S150-5PQ208C from AMD (formerly Xilinx) is a Spartan-II family FPGA with 150,000 system gates, 176 configurable logic blocks (CLBs), 208-pin PQFP package, and -5 speed grade (5 ns CLB delay). It serves as a reconfigurable digital logic fabric in industrial control I/O modules requiring deterministic timing and moderate gate count.

For engineers reviewing the XC2S150-5PQ208C datasheet, pinout, applications, or equivalent options, key selection factors include I/O count (176 user I/Os), distributed RAM capacity (144 kbits), global clock network support, and IEEE 1149.1 JTAG boundary-scan compliance for production testability.

Technical Context

The XC2S150-5PQ208C implements a hierarchical architecture with CLBs containing four 3-input LUTs and eight flip-flops per CLB, plus dedicated carry logic for arithmetic. It supports synchronous SRAM-based configuration via external PROM or microprocessor interface.

It features four global clock buffers, 176 user-configurable I/O pins with programmable slew rate and drive strength, and supports LVCMOS/LVTTL signaling standards. Configuration occurs through Master Serial, Slave Serial, or Boundary Scan modes using IEEE 1149.1 TAP controller.

Key Specifications

Pinout & Package

XC2S150-5PQ208C uses a 208-pin Plastic Quad Flat Pack (PQFP) with 0.5 mm pitch, 28 × 28 mm body size, and standard JEDEC MO-137AC footprint. Thermal pad is not present; power dissipation relies on PCB copper area and airflow.

Supply support for XC2S150-5PQ208C 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 develops adaptive computing platforms including FPGAs, adaptive SoCs, and AI engines.

The Spartan-II product line was designed for cost-sensitive, high-volume embedded applications requiring reconfigurable logic with predictable timing and industrial temperature operation.

FAQ

What is the operating temperature range for XC2S150-5PQ208C?

The XC2S150-5PQ208C is rated for commercial temperature range (0 °C to +70 °C). Its PQFP package and -5 speed grade are validated for stable operation within this range under specified VCCINT and VCCO conditions. Thermal derating is not required below 70 °C ambient, and no extended temperature variants exist for this specific speed/package combination.

Does XC2S150-5PQ208C support in-system programming?

Yes, XC2S150-5PQ208C supports in-system programming via its IEEE 1149.1 JTAG interface (TCK/TMS/TDI/TDO pins) and Master/Slave Serial configuration modes. This allows field firmware updates without removing the device from the PCB, provided the host controller or programming tool implements the proper configuration sequence defined in the Xilinx Spartan-II configuration guide.

What power supplies are required for XC2S150-5PQ208C?

XC2S150-5PQ208C requires two independent supplies: 2.5 V ± 3% for VCCINT (core logic) and 3.3 V or 2.5 V for VCCO (I/O banks), depending on selected signaling standard. Each I/O bank is independently configurable, allowing mixed-voltage operation across different pin groups without level-shifting components.

How many global clock inputs does XC2S150-5PQ208C provide?

XC2S150-5PQ208C provides four dedicated global clock inputs (GCK0–GCK3), each routed through low-skew networks to all CLBs and I/O blocks. These inputs support single-ended CMOS or LVTTL clock sources and are essential for building multi-clock-domain systems with deterministic timing behavior.

Is XC2S150-5PQ208C still in production?

No, XC2S150-5PQ208C is discontinued by AMD (Xilinx). Aetrix Electronics maintains legacy inventory and provides lifecycle coordination services, including last-time-buy planning, cross-reference support, and obsolescence mitigation strategies for ongoing production of systems originally designed with XC2S150-5PQ208C.
