16 Package

The TSYS01 is a single device Temperature Sensing

System (TSYS). 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 I

C 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 I

C interface.

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.

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).

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.
