FT221XS-R Overview
It is a part of the 20-SSOP (0.154, 3.90mm Width) package. This packaging has a Tape & Reel (TR)-shape, making it convenient to carry around. A reliable operation requires a temperature that is regulated to -40°C~85°C. It should work as long as you use a 3.3V~5VV power source. Among other things, it contains 20 terminations. 5V is the supply voltage that enables high efficiency. To operate, 20 pins are required. There are a total of MICROPROCESSOR CIRCUIT GPIOs, uCs, and peripheral ICs in this gadget. 11mA is set as the gadget's supply current. A 5.5V-volt supply voltage is recommended for maximum efficiency. Copper is the main component of this electrical component, which is part of the USBmadeEZ-FIFO, FT-X, X-Chip series. Component 3/5V is set to power supply. Operating current is 13.1mA at its maximum.
