MCP2221 Datasheet - Microchip

MCP2221 UART Protocol Converter

The MCP2221 is a USB-to-UART serial converter that enables USB connectivity in applications that have UART and/or I2C interfaces. The device reduces external components by integrating the USB termination resistors and the oscillator needed for USB operation. The MCP2221 has four GP pins for miscell.

MCP2221 Features
