In pin description table, added to function column:
“requires pull-up resistor” for SMDATA and SMCLK
pins
Identified 5V tolerant pins. Added the following
application note below table: “For the 5V tolerant
pins that have a pull-up resistor (SMCLK,
SMDATA, THERM, and ALERT), the voltage
difference between VDD and the pull-up voltage
must never exceed 3.6V.”
Updated voltage limits for 5V tolerant pins with
pull-up resistors.
Added the following note below table: “For the 5V
tolerant pins that have a pull-up resistor (SMCLK,
SMDATA, THERM, and ALERT), the pull-up
voltage must not exceed 3.6V when the device is
unpowered.”
Added leakage current.
“Preliminary” removed from table title
