XC3S400-4TQG144I Xilinx (AMD) Spartan-3 FPGA, 144-LQFP
XC3S400-4TQG144I is a cost-effective, high-performance SRAM-based FPGA from Xilinx (AMD) Spartan-3 family, built on 90nm process technology with 400K system gates, 8064 logic cells, and 294,912 bits of embedded RAM. It is housed in a 144-LQFP (TQFP-144, 20×20mm) surface-mount package, delivering 97 user I/Os and operating at a core voltage of 1.14V–1.26V, with an industrial temperature range of -40°C to +100°C (TJ). This device features four digital clock managers (DCMs) for clock synthesis and skew control, along with support for up to 622+ Mb/s I/O data rates and 18 single-ended/8 differential I/O standards including LVDS and RSDS.
Spartan-3 FPGA Features and Applications
This FPGA integrates a rich set of resources: 896 configurable logic blocks (CLBs), 1,872 Kbit block RAM, 520 Kbit distributed RAM, and dedicated 18×18 multipliers for DSP-intensive tasks. It supports DDR/DDR2 SDRAM interfaces up to 333 Mb/s and includes JTAG boundary scan (IEEE 1149.1/1532) for testing and configuration. The SelectIO™ interface provides digital control impedance termination, while eight global clock lines ensure high-speed, low-skew clock distribution. It is fully compatible with Xilinx ISE/WebPACK tools and supports embedded cores like MicroBlaze™ and PicoBlaze™ for system-on-chip (SoC) designs.
It is widely used in cost-sensitive, medium-complexity applications such as industrial motor controllers, automotive infotainment systems, consumer electronics, and communication protocol bridges. It also serves as a core component in medical devices, test equipment, and legacy embedded systems requiring reliable, reconfigurable logic with moderate I/O count and DSP capabilities.
