PIN FUNCTIONS CANSDAL (Pin 1):
Low Level CAN Bus Line. Carries the
EN/MODE (Pin 7):
MODE/Shutdown pin. Tie above 2.5V I2C data bus. to select master mode, float pin to select slave mode, or
CANSDAH (Pin 2):
High Level CAN Bus Line. Carries the pull this pin to ground for low-power shutdown mode. I2C data bus.
VCC (Pin 8):
Low Dropout Regulator Output and Device
CANSCLH (Pin 4):
High Level CAN Bus Line. Carries the Power Supply Input. Bypass this pin with a 2.2µF or I2C clock bus. greater capacitor to ground. Any bypass capacitors must be located as close to the pin as possible.
CANSCLL (Pin 5):
Low Level CAN Bus Line. Carries the I2C clock bus.
SCL (Pin 9):
Clock Input or Output Pin for the I2C Serial Port. When EN/MODE is 2.5V or above, the SCL pin is
GND (Pin 3 and Exposed Pad):
Ground. Solder the an input for the master clock. When EN/MODE is float- exposed pad and pin directly to the ground plane. ing, the SCL pin is an output for data received on the
V
CANSCLH/L pins.
IN (Pin 6):
Input Voltage Supply. This pin is the power supply input to the LDO. It must be locally bypassed with
SDA (Pin 10):
Data Input and Output Pin for the I2C a 1µF filter capacitor to GND as close to the pin as possi- Serial Port. ble. If the LDO function is unused, tie VIN to VCC.
