SERIAL COMMUNICATION FORMAT

The following diagram shows the TT1628/TT1668 serial communication format. The DIO Pin is an N-channel,

open-drain output pin; therefore, it is highly recommended that an external pull-up resistor (1KΩ to 10KΩ) must be

connected to DIO.

RECEPTION (DATA/COMMAND WRITE)

TRANSMISSION (DATA READ)

Where: twait (waiting time) ≥ 1µs

It must be noted that when the data is read, the waiting time (twait) between the rise of the eighth clock that has set

the command and the falling of the first clock that has read the data is greater or equal to 1µs.
