Interface - Controllers: SC18IS602BIPW, 128 application field and working principle

Interface controllers are used as electronic modules to bridge control and manage data communication between two electronic systems, relieving designers from the efforts to design and implement a complete communication interface.

One such interface controller is the SC18IS602BIPW. It is an 8-bit I2C-bus to SPI bridge into which up to 8 SPI-bus devices can be connected. It supports multi-master I2C-bus, including broadcast, allowing a group of SPI-bus devices to communicate with multiple SPI masters.

The SC18IS602BIPW is a 3.3 V device and is diode protected from voltage spikes greater than or equal to 7 V. It operates from -40 ºC to 85 ºC and is available in 128-pin LQFP package.

The features of SC18IS602BIPW include:

• I2C-bus to SPI-bus bridge interface
• Interrupt input to enable direct communication between the host and devices
• Operating voltage range from 1.65 V to 5.5 V
• Large SPI-bus data and address buses up to 24 bits, supporting chip selects with more than 8
• I2C-bus compatible feature to easily replace existing communication interface without modifying the software

The SC18IS602BIPW device supports up to 128 bytes of data. It also has two on-board registers, one for configuration settings and one for the SPI-bus slave address. It can be used in various application fields requiring multi-master serial communication such as industrial automation, medical instrumentation, energy management and automotive.

The working principle of the SC18IS602BIPW revolves around an 8-channel SPI/I2C bridge from a single I2C bus master. The master sends a control byte on the I2C bus, followed by the SPI slave address and the data to be transmitted. The bridge then interprets the control byte and transmits the required data to the designated SPI slave. In response, the slave may return back data, which is transmitted via the I2C bus back to the master.

The SC18IS602BIPW is ideal for many applications that require I2C-bus and SPI-bus communication, and it has the advantage of being much more energy efficient than traditional I2C-bus and SPI-bus solutions.

In conclusion, the SC18IS602BIPW is an 8-bit I2C-bus to SPI bridge with 128-bytes of memory available, and is suitable for applications requiring multi-master serial communication. It is a low-power and energy-efficient solution, and is supported by many industry-standard software packages.
