... Summary USB-I2C is a single chip USB to synchronous serial I2C slave interface. It greatly simplifies the connection of personal computer to a microcontroller capable of communicating in I2C master mode. In addition to the standard 2 I2C control lines, 11 additional Virtual I/O lines have custom-defined functionality. USB-I2C uses the Human Interface Device (HID) USB profile ...

... If the device is capable of operating while not plugged into a USB port, a USB Power Sense input should be provided. detected on the V+ pin of the USB connector used to reduce power consumption by entering into a sleep mode when the USB is not present, and also to ensure that the USB engine correctly initializes when the device is plugged in ...

... Oscillator X1/C2/C3 may be replaced by a low-cost resonator, provided its frequency tolerance is greater than 0.25%. C1 and C6 should be placed close to the USB connector. C7 should be placed near the Vss and Vdd pins of the USB-I2C and is required only if it would be some distance from C6 filter capacitor for an internal regulator and is required ...
