MICROCHIP MCP2221T-I/SL

The MCP2221A 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 MCP2221A has four GP pins for miscellaneous functionalities (including GPIO, USBCFG, SSPND, Clock Output, ADC, DAC and interrupt detector).
