Product Information

Back to top
iC-MCB is a BiSS slave bridging iC to implement BiSS slave functionality into any sensor technology and platform. A wide range of combinations can be covered with the iC-MCB on direct component access and via microcontroller host software solution support.

BiSS sensor implementations are possible. A downgrading configuration to SSI sensor operation is also possible.

Full BiSS C protocol functionality including Single Cycle Data (SCD) for sensors (SCDS) and Control communication for commands and register access. Real time critical effort for protocol response is handled by the iC-MCB directly and relieves the microcontroller host.

Typical applications use a device host microcontroller for providing data and coordinating control communications content. The host microcontroller configures and controls the iC-MCB via SPI interface. The iC-MCB can also be operated without any device sided microcontroller, just by BiSS device configuration boot sequence and self-sustaining operation.

iC-MCB can access and controls various sensors directly by an own SPI master interface.

The device operates in a wide supply range of 3 V .. 5.5 V and permits a single device supply. It is capable for the extended temperature range of -40° C to +125° C.

The integrated RS422 transceiver for the physical layer of the field interface (PHY) enables for BiSS point-to-point encoder applications. The maximum BiSS clock rate is 10 MHz.

The integrated I/O crossbar and an additional RS422 transceiver PHY enables BiSS bus structure applications. With the integrated I/O crossbar the BiSS bus structure position can be defined by configuration.

The BiSS diagnosis byte is supported with the I/O crossbar e.g. for U V W commutation signal transfer.

Symmetry Electronics is an authorized iC-Haus distributor.
