iC-MB4 Overview
iC-MB4 is a single-chip BiSS/SSI interface master controller featuring an 8-bit bus interface to industrial standard microcontroller. Alternatively an SPI interface enables serial munication between iC-MB4 and the connected microcontroller. The BiSS devices including one or several sensors are connected to the clock line MA and the data return line SL via point-topoint connection (Figure 1).
iC-MB4 Key Features
- Bidirectional BiSS munication with up to 8 slaves
- Supports SSI protocol for unidirectional data transmission
- Synchronous sensor data acquisition with cyclic transfer at data
- Configurable interface with TTL, CMOS, RS422 or LVDS
- Slave register operations during cyclic data transfers
- Automatic pensation of line delays and conversion times
- Data lengths of up to 64 bit for sensor data
- Data verification by CRC polynomials of up to 16 bits per slave
- Separate memory banks enable free controller access during
- 64 bytes memory for bidirectional register munication
iC-MB4 Applications
