产品简介：I2C (Inter-Integrated Circuit) Controller is a two-wire, bi-directional serial bus that provides simple and efficient method of data transmission over a short distance between many devices. Avalon compliant I2C Controller provides an interface between Nios II processor and I2C device. It can work as Master/Slave transmitter or Master/Slave receiver depending on working mode determined by Nios II processor. The I2C Controller IP core incorporates all features required by the latest I2C specification including clock synchronization, arbitration, multi-master systems and Fast-speed transmission mode.
It is provided as Altera SOPC Builder ready component and integrates easily into any SOPC Builder generated system.
