The TSYS01 provides factory calibrated temperature information. It includes a temperature sensing chip and a 24-bit ΔΣ-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. 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. 1 Analog tot Digital Conversion 2 Serial Peripheral Interface 3 Inter-Integrated Circuit 4 Quad Flat No-leads SENSOR SOLUTIONS ///TSYS01-FAMILY 09/2017 Page 1

TSYS01-FAMILY Digital Temperature Sensor INTERFACE DESCRIPTION PROTOCOL SELECTION PS pin input level has to be defined in dependence to protocol selection.  PS = 0 activates SPI.  PS = 1 activates I2C. I2C INTERFACE 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. I2C ADDRESS SELECTION The I2C address can be selected by CSB pin.  CSB=1 the address is 1110110x.  CSB=0 the address is 1110111x. Therefore, two TSYS01 can be interfaced on the same I2C bus. SPI INTERFACE 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 CS is pulled to low and ends when CS is pulled to high. SCLK is controlled by the SPI master and idles low (SCLK low on CS transitions, mode 0). A mode where the clock alternatively idles high is also supported (mode 3). COMMANDS The commands are the same for SPI and I2C interface. There are four commands:  Reset  Read PROM (calibration parameters)  Start ADC Temperature conversion  Read ADC Temperature result Command Hex Value Reset 0x1E Start ADC Temperature Conversion 0x48 Read ADC Temperature Result 0x00 PROM Read Address 0 0xA0 PROM Read Address 1 (Coefficient k4) 0xA2 PROM Read Address 2 (Coefficient k3) 0xA4 PROM Read Address 3 (Coefficient k2) 0xA6 PROM Read Address 4 (Coefficient k1) 0xA8 PROM Read Address 5 (Coefficient k0) 0xAA PROM Read Address 6 (SN23...8) 0xAC PROM Read Address 7 (SN7...0 and Checksum) 0xAE SENSOR SOLUTIONS /// TSYS01-FAMILY 09/2017 Page 5

TSYS01-FAMILY Digital Temperature Sensor RESET SEQUENCE The Reset sequence has to be sent once after power-on. It also can be used to reset the device ROM from an unknown condition. SPI I2C PROM READ SEQUENCE 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). SPI I2C SENSOR SOLUTIONS /// TSYS01-FAMILY 09/2017 Page 6

TSYS01-FAMILY Digital Temperature Sensor CONVERSION SEQUENCE 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 SPI The last clock will start the conversion which TSYS01 indicates by pulling SDO low. SDO goes high when conversion is completed. I2C 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. READ ADC RESULT After the conversion command the ADC result is read using ADC read command. Repeated ADC read commands, or command executed without prior conversion will return all 0 as result.
