BiSS INTERFACE MASTER
preliminary
Rev B2, Page 1/40
FEATURES
• Bidirectional BiSS communication with up to 8 slaves
• Supports SSI protocol for unidirectional data transmission
• Synchronous sensor data acquisition with cyclic transfer at data
rates of up to 10 Mbit/s
• Configurable interface with TTL, CMOS, RS422 or LVDS
• Slave register operations during cyclic data transfers
• Automatic compensation of line delays and conversion times
• Data lengths of up to 64 bit for sensor data,
configurable for each slave
• Data verification by CRC polynomials of up to 16 bits per slave
• Separate memory banks enable free controller access during
BiSS sensor data transfers
• 64 bytes memory for bidirectional slave register communication
• Parallel interface with 8 bit data/address bus services Intel and
Motorola devices with combined data and address bus
• Serial controller communication by SPITM-compatible mode
• Single 3 V to 5 V supply, industrial temperature range
APPLICATIONS
• Bidirectional communication in
multi sensor systems
• Linear and rotary encoders
• Motor feedback systems
• PLC systems
• Drives
