Features and Overview

  • Industry standard Philips I2C bus compatible interface
  • Emulates common I2C EEPROM interface
  • Only two pins (SDA and SCL) required to interface to I2C bus
  • Standard data rate of 100/400 kbps
  • High level API requires minimal user programming
     

The EzI2Cs User Module implements an I2C register-based slave device. The I2C bus is an industry standard, two wire hardware interface developed by Philips®. The master initiates all communication on the I2C bus and supplies the clock for all slave devices. The EzI2Cs User Module supports the standard mode with speeds up to 400 kbps. No digital or analog PSoC blocks are consumed with this module. The EzI2Cs User Module is compatible with multiple devices on the same bus.
