2-31TELCOM SEMICONDUCTOR, INC. PRELIMINARY INFORMATION TC12 GENERAL DESCRIPTION The TC12 is a monolithic temperature sensor that outputs a pulse waveform whose duty cycle varies in direct proportion to measured temperature. This output format is easily converted to binary data using logic or the counter/ timer circuit on-board the system microcontroller. Typical accuracy is ±1°C over the rated measurement range of – 40°C to +125°C. It operates from supply voltages as low as 2.7V. Unlike voltage output temperature sensors, the digital output of the TC12 offers superior immunity to system noise and does not require an A/D converter. Unlike two wire serial temperature sensors, the TC12 communicates over a single wire, and without complex serial protocol overhead.
