Microchip USB Controller MCP2221A-I/ST 1-Channel 12 Mbps 5.5V UART I2C 3V 14-Pin TSSOP

Microchip MCP2221A-I/ST is a versatile USB controller designed to bridge USB connections with UART and I2C interface protocols. It supports a single channel with a maximum data rate of 12 Mbps under USB 2.0 full-speed compliance, making it suitable for a wide range of embedded and industrial applications.

The device operates at a supply voltage from 3 V up to 5.5 V and comes in a compact 14-pin TSSOP surface mount package with a height of 1.05 mm and a length of 5 mm. Its integration of USB termination resistors and an internal oscillator streamlines system design and minimizes external components.

Featuring both UART and I2C communication protocols, the MCP2221A-I/ST includes a 128-byte buffer (split evenly between transmit and receive buffers) to handle data throughput efficiently at any baud rate. Furthermore, it provides four general-purpose pins configurable for GPIO, USB configuration, suspend mode, clock output, ADC, DAC, and interrupt detection functionalities, enhancing its flexibility in hardware control and USB chip configuration.

This USB controller supports full-speed USB 2.0 and implements a USB protocol composite device allowing Communication Device Class (CDC) for communications and configuration, plus Human Interface Device (HID) for I2C communication and device control.

The MCP2221A-I/ST is rated for operation within industrial temperature ranges (-40°C to 85°C), complemented by AEC-Q100 automotive standard compliance, enhancing its reliability in automotive and industrial environments. It draws a supply current of approximately 25 mA and is made in the United States.

Suitable for applications in electronics, automation, embedded systems, manufacturing, and laboratory equipment, this device enables efficient USB connectivity while reducing design complexity.
