Other (usage precautions)
1. Precaution when turning-on the power
As shown in the figure below, start transfer of the I2C bus command after factoring in the power-on time (A), RST
operation time (B) and command transfer start time (C).
A: Power-on time
This is the time taken from power-on to when the *VDD11 operating voltage has reached the lowest level (0.99V)
and operation has stabilized. The power-on-time depends on the characteristics of the power ICs and other
components, so it must be checked separately.
With regard to *VDD33 and *VDD11, *VDD11 must be turned on after *VDD33 has turned on.
B: PDWN operation time
This is the time during which the “L” level must be applied continuously for a period of 10ms or more to the PDWN
pin after the lowest level (0.99V) of the *VDD11 operating supply voltage has been reached and operation has
stabilized.
C: RESET operation time
This is the time during which the “L” level must be applied continuously for a period of 10ms or more to the RESET
pin after the PDWN is released (“H” level).
D: Command transfer start time
At least an interval of 10ms is required from the time RESET pin is released (“H” level) to the start of command
transfer.
