The Microchip MCP2221-I/ST is a composite USB device controller that bridges USB to I2C and UART communication protocols. It supports full-speed USB (12 Mb/s) and is compliant with USB 2.0 standards.
This controller features a wide operating voltage range of 3.0V to 5.5V and an industrial operating temperature range of -40°C to 85°C. It includes a 128-byte buffer for UART data throughput and a 64-byte buffer for I2C communication. The I2C master interface supports clock rates up to 400 kHz and can handle 7-bit or 10-bit addressable devices, with block read/write support up to 65,535 bytes. The UART interface supports baud rates from 300 to 115200.
With four general-purpose I/O pins, three ADC inputs, and one DAC output, the MCP2221-I/ST offers flexibility for various embedded applications. It is available in a 14-TSSOP package, suitable for surface-mount designs.
This device enumerates as a composite USB device using standard drivers for virtual COM port (VCP) on Windows operating systems. It is bus-powered or self-powered and includes configurable VID/PID assignments and string descriptors.
