TSYS01-FAMILYDigital Temperature Sensors Features • High Accuracy • Adjustment of high accuracy temp. range on request • Operating Temperature Range: -40°C ... +125°C • High Accuracy Temperature Sensor The TSYS01 is a single device, versatile, new technology temperature sensor. The TSYS01 provides factory calibrated temperature information. It includes a temperature sensing chip and a 24-bit AI-ADC. The essence of the digital 24-bit temperature value and the internal calibration values lead to highly accurate temperature information accompanied by high measurement resolution. The TSYS01 can be interfaced to any microcontroller by an I2C or SPI interface. This microcontroller has to calculate the temperature result based on the ADC values and the calibration parameters. • Industrial Control • Replacement of Thermistors and NTCs • Heating / Cooling Systems The basic operating principle is: • Converting temperature into digital 16/24 bit ADC value • Providing calibration coefficients • Providing ADC value and calibration coefficients by SPI or I2C interface.

Digital Temperature Sensor 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.

Digital Temperature Sensor Interface description PROTOCOL SELECTION PS pin input level has to be defined in dependence to protocol selection. A I2C communication message starts with a start condition and it is ended by a stop condition. Each command consists of two bytes: the address byte and command byte. Therefore, two TSYS01 can be interfaced on the same I2C bus. The serial interface is a 4-wire SPI bus, operating as a slave. CS (chip select), SCLK (serial clock), SDI (serial data in), and SDO (serial data out) are used to interact with the SPI master. Communication with the chip starts when...

Digital Temperature Sensor The commands are the same for SPI and I2C interface. There are four commands: • Read PROM (calibration parameters) • Start ADC Temperature conversion • Read ADC Temperature result From Master From Slave S = Start Condition P = Stop Condition W = Write A = Acknowledge R = Read N = Not Acknowledage

Digital Temperature Sensor The PROM Read command consists of two parts. First command sets up the system into PROM read mode. The second part gets the data from the system. Below examples are sequences to read address 3 (command 0xA6). From Master S = Start Condition From Slave P = Stop Condition From Master From Slave S = Start Condition P = Stop Condition W = Write A = Acknowledge R = Read N = Not Acknowledage A conversion has to be started by sending this command. The sensor stays busy until conversion is done. When conversion is finished the data can be accessed by using ADC read command...

Digital Temperature Sensor When the command is sent the TSYS01 stays busy until the conversion is done. All other commands except the reset command will not be executed during this time. When the conversion is finished the data can be accessed by sending a ADC read command, when an acknowledge appears from TSYS01.
