TSYS02D Digital Temperature Sensor High Accuracy Temperature Sensor 16 bit Resolution High Speed, low Response Time Low Power Consumption 2 I C Interface Small TDFN8 Package DESCRIPTION The TSYS02D is a single chip, temperature sensor. It provides factory calibrated data corresponding to the measured temperature. 2 The data is provided via I C interface. The temperature range is -40°C ... +125°C while the resolution is 0.01°C. 2 The TSYS02D can be interfaced to any microcontroller by an I C interface. The TDFN8 package provides smallest size and very fast time response.

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. 2 I C ADDRESS 2 The I C address is 0b1000000x. COMMANDS There are four commands: Reset Read PROM (serial number) Read ADC16 Temperature Data (with SCL hold) Read ADC16 Temperature Data (without SCL hold) Command Reset Read ADC16 Temperature Data (with SCL hold) Read ADC16 Temperature Data (without SCL hold) Read first 8 bytes of Serial Number Read last 6 bytes of Serial Number TSYS02D Rev 3 www.meas-spec.com 4/8 Hex Value 0x7E 0x E3 0x F3 0x FA0F 0x FCC9 2013-03 TSYS02D Digital Temperature Sensor RESET SEQUENCE The reset of TSYS02D can be sent at any time. When SDA line is blocked by an undefined state the only way to get the TSYS02D 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. CONVERSION AND ADC READ A conversion can be started by sending this command to TSYS02D. When the command is sent to the sensor it stays busy until conversion is done. All other commands except the reset command will not be executed during this time. When conversion is finished the data can be accessed by sending a Read command. If an acknowledge appears from the TSYS02D, you may then send 24 SCLK cycles to get all th result bits. Every 9 bit the system waits for acknowledge. If the acknowledge is not sent the data clocking out of the chip stops. Two types of conversion commands for temperature reading are possible. If the “hold” command is issued, the SCL is held low during conversion, indicating when the conversion is finished. If the “no hold” is issued, the SCL line is not controlled by the TSYS02D.

Part Name TSYS02D TSYS02P TSYS02S Description Digital Temperature Sensor, TDFN8, I2C Interface Digital Temperature Sensor, TDFN8, PWM Interface Digital Temperature Sensor, TDFN8, SDM Interface Order Number G-NIMO-003 G-NIMO-004 G-NIMO-005 EMC Due to the use of these modules for OEM application no CE declaration is done. 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.
