Slave Device (without automatic address)

[ansh11]

I am asking this question just for study purposes. Most i2c devices automatically increment the register address like DS1307. Is there any i2c device in which this doesn't happen? I can't find type of i2c device on google

It's not a matter of "type of i2c device". It rather depends on the implemented register map and how it can be accessed effectively. RTC and memory devices have continuous register files, they can be best accessed by auto increment. Respectively they are designed with this feature.

Temperature sensor LM75 has in contrast 4 different registers without auto-increment, also many ADC devices are designed similarly.

Thanks FvM
Can you name more devices I want to read the datasheet for further knowledge?

TI ADS1113. You can identify it yourself by considering which devices take advantage from auto-increment and which can be more effectively accessed by keeping the selected address.
