TSYS03 Digital Temperature Sensors Product Description The TSYS03* is a miniature digital temperature sensor that provides factory calibrated highly accurate temperature data. The device contains a durable temperature sensor element, A/D converter, and microcontroller to manage data communications via an I 2C interface. TSYS03 is available in a TDFN8 or a XDFN6 package to easily adapt to the space available on a PC board. These packages are very small and have low thermal mass which provides a quick response to temperature changes. The operating and measurement temperature range is -40 to +125°C with a resolution of ±0.01°C. Features  High Accuracy ±0.5°C @ Temp.: 0°C … +60°C  Adjustment of high accuracy temperature range on request Operating and sleep currents are extremely low making this sensor ideal for mobile and battery power applications.  I2C Interface up to 1MHz  Programmable I²C Address  Small IC-Package TDFN8 2.5mm x 2.5mm and XDFN6 1.5mm X 1.5mm  Low Supply Current < 5 μA (standby < 0.3 μA)  Operating Temperature Range: -40°C … +125°C Applications  Consumer goods and appliances  HVAC and weather stations  Industrial Control and food monitoring  Vehicle battery monitoring  Medical probes and patient monitoring *Temperature System Sensor SENSOR SOLUTIONS /// DATASHEET TSYS03 11/2019 Page 1 TSYS03 Digital Temperature Sensors Absolute Maximum Ratings Absolute maximum ratings are limiting values of permitted operation and should never be exceeded under the worst possible conditions either initially or consequently. If exceeded by even the smallest amount, instantaneous catastrophic failure can occur. And even if the device continues to operate satisfactorily, its life may be considerably shortened.

Each command consists of two bytes: the address byte and command byte. I2C Address The standard I2C address is 0x40 (0b0100000x). Every sensor will respond to this address. But the sensor can also react to a second, alternative I2C address. It is possible to do a one-time subsequent writing of an alternative static I2C address. This leads to a wrong memory CRC but the sensor is still functional. The alternative address could be written to the sensor already during production. There won’t be a wrong CRC at the end in this case. It is also possible to write an alternative I2C address to the sensor during operation. This address is temporally and is overwritten during a software reset or a hardware restart. Further information on writing the alternative I2C address are given in the Application Note. SENSOR SOLUTIONS /// DATASHEET TSYS03 11/2019 Page 4 TSYS03 Digital Temperature Sensors Commands There are four commands:     Reset Read Serial Number Start Conversion Read ADC Command Hex Reset 0x1E Read Serial Number 0x0A Start Conversion 0x46 Read ADC 0x00 Reset Sequence The reset of TSYS03 can be sent at any time. When SDA line is blocked by an undefined state the only way to get the TSYS03 to work is to send a power on reset or several SCL cycles. This is not needed when the last command was not a conversion. Start Conversion A conversion must be started and conducted before the ADC result can be read. Reading ADC Result The temperature reprinting ADC result is read including CRC checksum. SENSOR SOLUTIONS /// DATASHEET TSYS03 11/2019 Page 5 TSYS03 Digital Temperature Sensors Read Serial Number The serial number is written to non-volatile memory along with other values during production. It represents the chip position on the production wafer. CRC byte The CRC byte can be used to check for bad data. It is determined over the entire data using polynomial 0x31.

Especially line coupled disturbances like surge, burst, HF etc. cannot be removed by the module due to the small board area and low price feature. There is no protection circuit against reverse polarity or over voltage implemented. The module will be designed using capacitors for blocking and ground plane areas in order to prevent wireless coupled disturbances as good as possible.
