Overview

Use the I2C Designer tool to quickly resolve conflicts in addressing, voltage level and frequency in I2C based designs. Enter master and slave inputs to automatically generate an I2C tree or easily build a custom solution. This tool will help designers save time and comply with the I2C standard with guidance on debugging a missing acknowledgment, selecting the pullup resistors and meeting the maximum capacitance load of an I2C bus. 
Features
  • GUI-based web application
  • Exportable designs
