OVERVIEW

• I2C is a two-wire, bi-directional serial bus that
  provides a simple and efficient method of data
  transmission over a short distance between many
  devices. It can work as a master transmitter or
  master receiver depending on working mode
  determined by microprocessor/microcontroller. The
  DI2CX cores incorporates all features required by
  the latest I2C specification including clock
  synchronization, arbitration, multi-master
  systems and High-speed transmission mode. They
  can work as a transmitter or receiver depending
  on working mode. Built-in timers allows operation
  from a wide range of the clk frequencies.

I2C Controllers

• DI2CM I2C Bus controller Master realize master
  communication between microprocessor /
  microcontroller and I2C Bus. Allow operations as
  I2C master transmitter and I2C Master receiver.
• DI2CS - I2C Bus controller Slave realize slave
  communication between microprocessor /
  microcontroller and I2C Bus. Allow operations as
  I2C Slave receiver and I2C Slave transmitter.
• DI2CSB I2C Bus controller Slave base version
  realize communication between I2C Bus and a
  passive devices like LCD drivers, memories etc.
