Pin Definitions and Functions

Symbol

Function

1RO

Reset Input/Output; open drain output, integrated pull-up resistor; active low.

2CSN

SPI Chip Select Not Input; CSN is an active low input; serial communication is

enabled by pulling the CSN terminal low; CSN input should be set to low only when

CLK is low; CSN has an internal pull-up resistor and requires CMOS logic level

inputs.

3CLK

SPI Clock Input; clock input for shift register; CLK has an internal pull-down resistor

and requires CMOS logic level inputs.

4SDI

SPI Data Input; receives serial data from the control device; serial data transmitted

to SDI is a 16-bit control word with the Least Significant Bit (LSB) transferred first:

the input has a pull-down resistor and requires CMOS logic level inputs; SDI will

accept data on the falling edge of the CLK signal.

5SDO

SPI Data Output; this tri-state output transfers diagnostic data to the control device;

the output will remain tri-stated unless the device is selected by a low on Chip Select

Not (CSN).

6GND

Ground

7n.c.

Not connected

Power Supply Input; block to GND directly at the IC with ceramic capacitor. Ensure

to have no current flow from PIN8 to PIN9. PIN8 and PIN9 can be directly connected.

Power Supply Input; block to GND directly at the IC with ceramic capacitor. Ensure

Bus1

LIN Bus 1; Bus line for the LIN interface, according to ISO. 9141 and LIN

specification 2.1 as well as SAE J2602-2.

cc3 shunt

PNP Shunt; External PNP emitter voltage.

cc3 base

PNP Base; External PNP base voltage.

GND

Ground

cc3REF

External PNP Output Voltage

INT

Interrupt Output, configuration Input; used as wake-up flag from SBC Stop Mode

and indicating failures. Active low. Integrated pull up. During start-up used to set the

SBC configuration. External Pull-up sets config 1/3, no external Pull-up sets config

2/4.

cc1 µc

Voltage Regulator Output; 5 V supply; to stabilize block to GND with an external

capacitor.

cc2

Voltage Regulator Output; 5 V supply; to stabilize block to GND with an external

capacitor.

ccHSCAN

Supply Input; for the internal HS CAN cell.

CANH

CAN High Line; High in dominant state.

SPLIT

Termination Output; to support recessive voltage level of the bus lines.

CANL

CAN Low Line; Low in dominant state.

GND

Ground

TxDCAN

CAN Transmit Data Input; integrated pull-up resistor.

RxDCAN

CAN Receive Data Output

TxDLIN

LIN Transceiver Data input; according to ISO 9141 and LIN specification 2.1 as

well as SAE J2602-2. integrated pull-up resistor.
