Microchip MCP2221A-I/ML, USB Controller, 12Mbps, I2C, UART, 16-Pin QFN

The MCP2221 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 MCP2221 also has four GP pins providing miscellaneous functionalities (GPIO, USBCFG, SSPND, Clock Output, ADC, DAC, interrupt detector).Universal Serial Bus (USB) Supports full-speed USB (12 Mb/s) Implements USB protocol composite device: Communication Device Class (CDC) for Communications and configuration Human Interface Device (HID) for I2C™, chip control and configuration 128-byte Buffer to handle data throughput at any UART baud rate: 64-byte Transmit 64-byte Receive Human Interface Device (HID) for both I2C™ communication and control. 64 byte buffer to handle data throughput at any I2C™ baud rate Fully configurable VID and PID assignments, and string descriptors Bus-powered or self-powered USB 2.0 Compliant
