The I2C is a two-wire, bi-directional serial bus, which provides a simple and efficient method of short distance data transmission between many devices. The DI2CSB provides an interface between a passive target device e.g. memory, LCD display, pressure sensors etc. and an I2C bus. It can work as a slave receiver or as a transmitter - depending on the working mode, determined by the master device. A very simple interface, composed with read, write and data signals, allows easy connection to target devices. The core does not require any programming and is ready to work after power up/reset. The read, write, burst read, burst write and repeated start transmissions are automatically recognized by the core. The core incorporates all features required by the I2C specification. The DI2CSB supports the following transmission modes: Standard, Fast and High Speed.
The DI2CS is a technology independent design which can be implemented in a variety of process technologies.
