Transmitter input of the LS CAN interface
This 5.0 V pin is a 3% low drop voltage regulator dedicated to the microcontroller supply.
Receiver output of the LS CAN interface
This is an Input/Output pin.
This output is asserted LOW when an enabled interrupt condition occurs.
These device ground pins are internally connected to the package lead frame to provide
a 33389-to-PCB thermal path.
This pin is the tri-state output from the shift register.
This pin is for the input of serial instruction data.
This pin clocks the internal shift registers.
This pin communicates with the system MCU and enables SPI communication.
Input interfaces to external circuitry. Levels at these pins can be read by SPI and input
can be used as programmable wake-up input in Sleep or Stop mode.
This pin does not connect.
Pin for the connection of the bus termination to CANH
CAN low input/output
CAN high input/output
This 5.0 V pin is a low drop voltage regulator dedicated to the peripherals supply.
Pin for the connection of the bus termination to CANL
This pin is voltage supply from the battery.
This pin is a 10 Ω switch to V
