XC3S50-4PQ208I

The Xilinx XC3S50-4PQ208I is a Field Programmable Gate Array (FPGA) belonging to the Spartan-3 series. This device offers 1728 logic elements and 192 logic array blocks, providing a capacity of up to 50,000 gates. It includes 73,728 bits of on-chip RAM and supports 124 I/O pins, making it suitable for entry-level to moderate FPGA applications.

Designed for efficient power usage, the XC3S50-4PQ208I operates at a low voltage range of 1.14V to 1.26V. It is built to function reliably across an industrial temperature range, from -40°C to +100°C (junction temperature).

The FPGA is housed in a 208-pin BFQFP (Plastic Quad Flat Package) with a body size of 28x28 mm, designed for surface mounting on PCBs. Its structure consists of programmable logic blocks and interconnects, along with configurable I/O blocks and built-in memory cells.

This component is suitable for applications such as industrial control, embedded system design, digital signal processing, communication equipment, and consumer electronics where flexible logic and moderate gate count are required. Due to its obsolete status, it is best suited for legacy designs or where long-term supply is not a primary concern.
