AP1625

The AP1625 is designed as the Inter-Integrated Circuit bus that has been developed by Philips. It allows integrated circuits to communicate directly with each other via a simple bi-directional 2-wire bus. The two bus lines are serial clock line (SCL), and serial data line (SDA). Nowadays, the I2C-bus becomes a standard bus system which is used in consumer electronics, telecommunications, and industrial electronics.

Each information of the AP1625 put on the SDA line must be 8-bit long. The data is transferred serially with the most significant bit first, and followed by an acknowledge bit. The 9th clock pulse of the acknowledge bit is generated by the master. The transmitting device has to release the SDA line (HIGH or in the high impedance state) during this clock pulse while the device that needs to acknowledge has to pull down the SDA line during this clock pulse.
