DI2CSB - I2C Bus Interface Slave (base version) Description:


I2C is a two-wire, bi-directional serial bus that provides a simple and efficient method of data transmission over a short distance 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 works as a slave receiver or transmitter depending on working mode determined by a master device. Very simple interface, composed with the read, write and data signals, allows easy connection to the target devices. The core doesn’t required 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 I2C specification. The DI2CSB supports the following transmission modes: Standard, Fast and High Speed.
DI2CSB is a technology independent design that can be implemented in a variety of process technologies.


■ Conforms to v.2.1 of the I2C specification
■ Slave operation
■ Master transmitter
■ Master receiver
■ Supports 3 transmission speed modes
■ Standard (up to 100 kb/s)
■ Fast (up to 400 kb/s)
■ High Speed (up to 3,4 Mb/s)
■ Allows operation from a wide range of input clock frequencies
■ Support for reads, writes, burst reads, burst writes, and repeated start
■ 7-bit addressing
■ No programming required
■ Simple interface allows easy connection to target device e.g. memory, LCD display, pressure sensors etc.
■ Fully synthesizable
■ Static synchronous design
■ Positive edge clocking and no internal tri-states
■ Scan test ready


■ Getting a sillicon proven IP
■ Rapid prototyping and time-to-market reduction
■ Design risk elimination
■ Development costs reduction
■ Full customization
■ Technological independence (VHDL and Verilog)
■ Global sales network
■ Professional service
