MCP2221-I/ST Product Details

The MCP2221-I/ST is an USB-to-UART Serial Converter 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. It has four GP pins for miscellaneous functionalities (including GPIO, USBCFG, SSPND, Clock Output, ADC, DAC and interrupt detector). It enumerates as a composite USB device after Power-on Reset (POR). The device enumerates as both a Human Interface Device (HID) for I²C, GPIO control and as CDC for the USB-UART converter. The bus-matrix module is the heart of the MCP2221. All other modules are tied together and controlled via the bus-matrix module. This module manages the data transfers between the USB and the UART, the I²C Master module, as well as the command requests generated by the USB host controller and commands for controlling the function of the UART, GPIO, ADC, DAC and Clock Output.
