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

Product Overview The MCP2221-I/P is an USB 2.0 to UART/I²C™ Protocol Converter with GPIO enables USB connectivity in applications that have an UART and I²C interfaces. The device reduces external components by integrating the USB termination resistors and the oscillator needed for USB operation. The MCP2221 also has four GP-pins providing miscellaneous functionalities (GPIO, USBCFG, SSPND, clock output, ADC, DAC, interrupt detector). The MCP2221 enumerates as a composite USB device after POR. The device enumerates as both a human interface device (HID) for I²C, GPIO control and as CDC for the USB-to-UART converter. Supports full-speed USB (12Mbps) Implements USB protocol composite device 128-byte buffer to handle data throughput at any UART baud rate Human interface device (HID) for both I²C™ communication and control USB 2.0 compliant Human interface device (HID) for both I²C™ communication and control I²C/SMBus terminal Communications device class (CDC) for the USB-to-UART option Device runs as an I²C master Data to write/read on the I²C bus is conveyed by the USB interface Four general-purpose input/output pins All GP pins can be assigned to other functionalities UART activity LED outputs (UTX and URX) SSPND output pin USBCFG output pin (indicates when the enumeration has completed) Three ADC inputs One DAC with two possible output options 12MHz or other configurable values clock reference output External interrupt edge detection Applications Industrial, Communications & Networking Product Information Bridge Type: USB to I2C, SMBUS, UART Supply Voltage Min: 3V Supply Voltage Max: 5.5V Interface Case Style: DIP No. of Pins: 14Pins Operating Temperature Min: -40°C Operating Temperature Max: 85°C Product Range: - Automotive Qualification Standard: - MSL: -
