MCP2221-I/P

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
