XC3S50A-4VQG100I

XC3S50A-4VQG100I Spartan-3A FPGA IC 68 55296 1584 100-TQFP

The XC3S50A-4VQG100I is a high-performance field-programmable gate array (FPGA) from Xilinx, belonging to the Spartan-3A family, designed for cost-effective, low-power embedded and industrial applications. It features 50,000 system gates, 1,728 logic cells, and integrated 9KB of block RAM (including 2KB distributed RAM), supporting flexible logic configuration and high-speed data processing. Built on 90nm CMOS technology, it offers excellent performance-to-cost ratio, with a 4ns typical clock-to-output delay and 200MHz maximum operating frequency. Equipped with 36 I/O pins, 2 dedicated DLLs (Delay-Locked Loops) for clock management, and support for SPI and I2C communication protocols, it is ideal for implementing custom logic circuits.

Operating at a 1.2V core supply voltage and 1.2V-3.3V I/O supply voltage, the XC3S50A-4VQG100I operates reliably across -40°C to 85°C industrial temperature range. It has a typical power consumption of 120mW (active mode) and 10μW (standby mode), optimizing energy efficiency for battery-powered and low-power designs. The FPGA chip supports 3.3V LVTTL/LVCMOS I/O standards, with a maximum I/O current of 24mA per pin, ensuring compatibility with most microcontrollers and peripheral devices.
