MCP2221A-I/P - USB 2.0 to I^2C/UART Protocol Converter with GPIO
The MCP2221A is a USB-to-UART/I2C serial converter which enables USB connectivity
in applications that have a UART and I2C interfaces. The device reduces external
components by integrating the USB termination resistors and the oscillator needed
for USB operation. The MCP2221A also has four GP pins providing miscellaneous
functionalities (GPIO, USBCFG, SSPND, Clock Output, ADC, DAC, interrupt detector).
