I2C_SCL 46
3.6.2

Signal Description

Both SDA and SCL are bidirectional lines, connected to a positive supply via a pull-up resistor
respectively. When the bus is free, both lines are high.

Design Guide

For SIM5215&SIM5216, the data on the I2C bus can be transferred at rates up to 400kbps. The number of
peripheral devices connected to the bus is solely dependent on the bus capacitance limit of 400pF. Note
that PCB traces length and bending are in users' control to minimize load capacitance.
：
Note I2C_SDA and I2C _SCL have been pulled up with two 2.2kR resistors to 2.6V level in module. So there is no need
to pull them up in users' application circuit.
