Note:
Serial communications
The STTS424E02 has a simple 2-wire SMBus™/I
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 STTS424E02 registers in order to customize device operation.
Device type identifier (DTI) code
The JEDEC temperature sensor and EEPROM each have their own unique I
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 others’ operation
in any way. The DTI codes are:
●

●
The EEPROM in the STTS424E02 package has its WC pin internally tied to the V
(Ground) pad inside the package while the A0, A1, and A2 pins in the logic diagram (see
Figure 1 on page
'0011' for the TS, and
'1010' for addressing the EEPROM memory array, and
‘0110’ to access the software write protection settings of the EEPROM.
8) correspond to the chip enable pins E0, E1 and E2 of EEPROM.
