Microchip (MCP2221-I/P) Interface Bridges, USB to I2C, SMBUS, UART

Product OverviewThe MCP2221-I/P is an USB 2.0 to UART/I²C Protocol Converter with GPIO enablesUSB connectivity in applications that have an UART and I²C interfaces. Thedevice reduces external components by integrating the USB termination resistorsand the oscillator needed for USB operation. The MCP2221 also has four GP-pinsproviding miscellaneous functionalities (GPIO, USBCFG, SSPND, clock output, ADC,DAC, interrupt detector). The MCP2221 enumerates as a composite USB device afterPOR. The device enumerates as both a human interface device (HID) for I²C, GPIOcontrol and as CDC for the USB-to-UART converter.Supports full-speed USB (12Mbps)Implements USB protocol composite device128-byte buffer to handle data throughput at any UART baud rateHuman interface device (HID) for both I²C communication and controlUSB 2.0 compliantHuman interface device (HID) for both I²C communication and controlI²C/SMBus terminalCommunications device class (CDC) for the USB-to-UART optionDevice runs as an I²C masterData to write/read on the I²C bus is conveyed by the USB interfaceFour general-purpose input/output pinsAll GP pins can be assigned to other functionalitiesUART activity LED outputs (UTX and URX)SSPND output pinUSBCFG output pin (indicates when the enumeration has completed)Three ADC inputsOne DAC with two possible output options12MHz or other configurable values clock reference outputExternal interrupt edge detectionApplicationsIndustrial, Communications & NetworkingProduct InformationBridge Type: USB to I2C, SMBUS, UARTSupply Voltage Min: 3VSupply Voltage Max: 5.5VInterface Case Style: DIPNo. of Pins: 14PinsOperating Temperature Min: -40°COperating Temperature Max: 85°CProduct Range: -Automotive Qualification Standard: -MSL: -
