    Application Note Temperature Sensor IC 1. TSic 206/203/201/306/316/303/301 The TSic series of temperature sensor ICs are specifically designed as a low-power solution for temperature mea- surement in building automation, medical/pharma tech- nologies, industrial and mobile applications. The TSic pro- vides a simple temperature measurement and achieves outstanding accuracy combined with long term stability.

    The TSic has a high precision bandgap reference with a PTAT (proportional-to-absolute-temperature) output, a low-po- wer and high-precision ADC and an on-chip DSP core with an EEPROM for the precisely calibrated output signal. The IST AG TSic sensor is fully tested and calibrated to ensure the guaranteed accuracy. Output Examples Temperature Range: -10 °C to +60 °C...
  • Page 6 5.2 Temperature Transmission Packet from a TSic The TSic transmits 1-byte packets. These packets consist of a start bit, 8 data bits, and a parity bit. The nominal baud rate is 8 kHz (125 µsec bit window). The signal is normally high. When a transmission occurs, the start bit occurs first followed by the data bits (MSB first, LSB last).
  • Page 7 4 different settings: 250 Hz, 10 Hz, 1 Hz, and 0.1 Hz. This is done during calibration of the sensor on IST AG side. The standard update rate is 10 Hz (TSic 206, TSic 306, TSic 506) or 1 Hz (TSic 716). For other update rates please contact IST AG.
  • Page 8 5.7 Solutions if Real Time System Cannot Tolerate the TSic Interrupting the µController Some real time systems cannot tolerate the TSic interrupting the µController. The µController must initiate the tempe- rature read. This can be accomplished by using another pin of the µController to supply V to the TSic.
