MCP2221A-I/P Datasheet PDF - Microchip

●The MCP2221A 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 MCP2221A also has four GP pins providing miscellaneous functionalities (GPIO, USBCFG, SSPND, Clock Output, ADC, DAC, interrupt detector).

● Supports full-speed USB (12 Mb/s)

● 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

● Fully configurable VID and PID assignments, and string descriptors

● Bus-powered or self-powered

● USB 2.0 Compliant
