DI2CSB

DI2CSB bridge to APB, AHB, and AXI bus, provides an interface between a passive target device e.g. memory, LCD display, pressure sensors, etc., and the I2C bus. It can work as:

• a slave receiver or
• transmitter

depending on a working mode determined by the master device. A very simple interface, composed of reading, 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. Read, write, burst read, burst write and repeated start transmissions are automatically recognized by the core. The solution incorporates all features required by the I2C specification. The DI2CSB supports the following transmission modes:

• Standard,
• Fast,
• Fast Plus, 
• High Speed.

The DI2CS is a technology-independent design and can be implemented in various process technologies.
