General Description
The MCP2221 is a USB-to-UART serial converter that enables USB connectivity in applications that have UART and/or I2C interfaces.
The device reduces external components by integrating the USB termination resistors and the oscillator needed for USB operation.
Key Features
- Universal Serial Bus (USB).
- Supports Full-Speed USB (12 Mb/s).
- Implements USB Protocol Composite Device: - Communication Device Class (CDC) for USB-to-UART Conversion - Human Interface Device (HID) for I2C™ Device Control and Configuration.
- 128-byte Buffer to Handle Data Throughput at Any Supported 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.
