The iC-MBE is a compact BiSS/SSI interface master featuring an on-chip RS-422 transceiver and a 20 Mbit/s SPI suitable to implement BiSS/SSI master functionality into any device or platform. Up to eight sensors or actuators can be connected. Two physical BiSS/SSI channels enable single-ended communication via internal CMOS and TTL transceivers. Alternatively, one differential BiSS/SSI interface with on-chip RS-422 transceiver can be enabled. iC-MBE is designed for a supply voltage of 3.3 V to 5.0 V and comes in a space-saving QFN16-3x3 mm² package.

Features:

• Bidirectional BiSS communication with up to 8 slaves
• Supports SSI protocol for unidirectional data transmission
• Isochronous sensor data acquisition with data rates of up to 10 Mbit/s

• >one differential channel with RS-422 transceivers
• Slave register accesses during cyclic data transfers
• Automatic line delay compensation
• Configurable data lengths of up to 64 bit for each sensor
• CRC verification with up to 16 bits per slave
• Two memory banks for free controller access during BiSS sensor data transfers
• 64 bytes memory for bidirectional register access

The iC-Gi22 dual-channel inductive sensor IC with sin/cos and interpolated SSI data output is used for magnetic off-axis position sensing using a simple metal target. The device enables absolute angle detection over the entire mechanical revolution by sampling two separate channels (master plus slave). The demodulated receiver signals feed the external processor, i.e. a suitable nterpolation device such as the iC-MNF, iC-TW29, iC-NQE, and an MCU with ADCs, to determine the position with higher resolution.

Features:

• Adjustable transmitter with coil driver (2-5 MHz, up to 20 mA)
• Two independent receiver channels with demodulation and line driver (1 Vdiff @ 100 Ω)
• High level output with selectable center voltage
• Adjustable coarse (x1...10) and fine gain (x1...20)
• Precision offset correction (via 11 bits up to 200 mV)
• Automatic gain control (per channel)
• Sin/cos interpolation with 8-bit resolution (1 channel)
• Angle output via SSI with error and warning
• I2C multi-master for self-configuration from external EEPROM
• I2C slave interface to the system (MCU)
• Operation monitoring with alarm masking: signal loss, I/O short circuit, RAM CRC
• Signal frequency up to 50 kHz (allows for 90000 rpm minimum)
• Power supply from 3.3 V to 5 V, approx. 15 mA
• Space-saving 32-pin QFN with 5x5 mm
