Overview
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.

The I2C (Inter-Integrated Circuit) Bus invented in 1980 by Philips Semiconductors (NXP Semiconductors today) was a massive step forward in simplifying communications in embedded systems. It is a simple two-wire interface for synchronous, multi-master/multi-slave, single ended serial communication. Fast forward 45 years to today and it is still widely used for attaching low speed peripheral Integrated Circuits (ICs), processors and microcontrollers. But silicon today has changed...
Early in my career selling chips for Motorola Semiconductor, the ability to spin derivative microcontroller chips for a customer’s specific requirement was relatively straightforward. If the volume looked reasonable, we would tape-out a new chip with a few added features because mask costs and wafers were relatively inexpensive at the larger process nodes. The customer won by getting an MCU tailored to their specific need, and Motorola won by gaining a more committed customer plus another SKU that could be sold to other customers – boosting ROI. With the migration to higher cost FinFET nodes, those times are long gone as the economics no longer work.

Imagine a camera subsystem that responds in microseconds, consumes less power, and offers a more straightforward route to time-to-market. For SoC architects and IP integration teams, that vision is increasingly possible with MIPI Camera Control Interface (CCI) over I3C.
