Serial communications

The STTS2002 has a simple 2-wire SMBus/I2C-compatible digital serial interface which

allows the user to access both the 2 Kb serial EEPROM and the data in the temperature

register at any time. It communicates via the serial interface with a master controller which

operates at speeds of up to 400 kHz. It also gives the user easy access to all of the

STTS2002 registers in order to customize device operation.

2.1

Device type identifier (DTI) code

The JEDEC temperature sensor and EEPROM each have their own unique I2C address,

which ensures that there are no compatibility or data translation issues. This is due to the

fact that each of the devices have their own 4-bit DTI code, while the remaining three bits

are configurable. This enables the EEPROM and thermal sensors to provide their own

individual data via their unique addresses and still not interfere with each other’s operation

in any way. The DTI codes are:

● '0011' for the TS, and

● '1010' for addressing the EEPROM memory array, and

● ‘0110’ to access the software write protection settings of the EEPROM.
