8.2.1.1 UJA106x with PCA9703, standby
8.2.1 SBC wake port extension with cyclic biasing
System Basis Chips (SBC) offer many functions needed for in-vehicle networking
solutions. Some of the features built into SBC are:

Transceivers (HS-CAN, LIN 2.0)
Scalable voltage regulators
Watchdog timers; wake-up function
Fail-safe function
PCA9703 fits to SBC UJA106x and UJA107x family
PCA9703 can be powered by V1 of SBC
Extends the SBC with 16 additional wake inputs
μC can be set to stop-mode during standby to save ECU standby current. SBC with
GPI periodically monitors the wake inputs
– Cyclic bias via V3
– Very low system current consumption even with clamped switches
– Interrupt enable control via V2
