MCP2221A-I/SL

The MCP2221A-I/SL from Microchip Technology is a highly integrated USB-to-UART and USB-to-I²C bridge IC. It utilizes a driverless HID architecture, simplifying embedded development and sensor debugging.

Key technical specifications include USB 2.0 Full-Speed compliance, UART speeds up to 460.8 kbps, and I²C master interface speeds up to 400 kHz. The device integrates General Purpose Input/Output (GPIO), a 10-bit Analog-to-Digital Converter (ADC), and a 5-bit Digital-to-Analog Converter (DAC). It operates over a supply voltage range of 3.0V to 5.5V and has a typical supply current of 13mA.

This bridge IC is housed in a 14-SOIC package and is designed for surface mount applications. The operating temperature range is -40°C to +85°C, making it suitable for industrial environments. Its driverless HID implementation eliminates the need for custom drivers, reducing development time and BOM costs.

Typical applications include I²C sensor debugging, MCU serial debugging, USB-to-I²C adapters, IoT prototyping, and production testing tools. The integrated multi-function I/O makes it a versatile component for various interface needs.
