Table 2.1, "EMC1402 Pin

Description"

In pin description table, added to function column:

“requires pull-up resistor” for SMDATA and SMCLK

pins

Table 2.1, "EMC1402 Pin

Description"

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.”

Table 3.1, "Absolute

Maximum Ratings"

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.”

Table 3.2, "Electrical

Specifications"

Added leakage current.
