MCP2221A - UART Protocol Converter

Datasheet Summary

Description

The MCP2221A 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.

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.
448-Byte Buffer to Handle Data Throughput at Any Supported UART Baud Rate: - 64-byte transmit - 384-byte receive.
Human Interface Device (HID) for Both I2C Communication and Control: 64-byte buffer to handle data throughput.
