Microchip Technology's MCP2221A-I/SL: A Versatile USB-to-I2C/UART Protocol Converter

The MCP2221A-I/SL is a highly integrated USB-to-I2C/UART serial converter from Microchip Technology, which facilitates seamless communication between USB and I2C or UART interfaces. This compact and efficient IC is housed in a 14-pin SOIC package, making it an ideal solution for applications requiring simple USB connectivity to communicate with legacy serial devices or I2C-enabled components.

With the MCP2221A-I/SL, developers can easily implement USB in their designs without extensive knowledge of the USB protocol, thanks to its full-speed USB 2.0-compliant interface at 12 Mbps. The device supports USB suspend, resume, and remote wakeup operations, providing a power-efficient solution for modern, energy-conscious applications.

Key Features:

• USB-to-UART serial converter with full modem control and hardware flow control support.
• Integrated USB transceiver; no external resistors required.
• 256 bytes of user EEPROM, with write protection features for storing user data and configurations.
• Four GPIO pins that offer versatility for additional control and interfacing.
• Configurable clock output (between 1.5 MHz and 12 MHz) for driving a microcontroller or other logic.
• Supports I2C speeds up to 400 kHz and UART baud rates from 300 bps to 460.8 kbps.
• Comprehensive operating voltage range of 3.0V to 5.5V, catering to a variety of logic levels and power supplies.

The MCP2221A-I/SL also comes with an array of built-in features to ensure robust operation, such as over-current protection, thermal shutdown, and under-voltage lockout. These protections ensure reliable performance across diverse operating conditions.

Ideal for applications such as PC peripherals, battery chargers, and consumer electronics, the MCP2221A-I/SL is a versatile bridge between USB and serial communication protocols. Its ease of use, combined with Microchip's support and resources, makes it a go-to choice for designers looking to add USB connectivity to their embedded projects.
