MCHPMCP2221AT-I/SL
Overview
The MCP2221AT-I/SL is a USB 2.0 to I2C/UART protocol converter that enables easy peripheral communication from a host computer. It integrates a 12 MHz internal oscillator and requires no external crystal, while also providing 4 GPIO pins and integrated ADC/DAC peripherals. This bridge is a complete solution for adding USB connectivity to legacy serial designs or interfacing PC-based software with I2C sensors.
Why Choose This Part
The device simplifies hardware design by eliminating the need for an external crystal and provides highly versatile I/O with 10-bit ADC and 5-bit DAC capabilities on the GPIO pins. Its wide 3.0V to 5.5V supply range and industrial temperature rating make it robust for both consumer and industrial environments.
