TSic series high precision temperature sensor
TSic; series of high-precision temperature sensors
The Tsic product range consists of integrated chips and calibrated temperature sensors. Internally, a signal converter for analog or digital signal output is integrated. It provides measurement accuracy from + 0.5 C to very low + 0.1 degrees C, and has (0.1 degrees C) to as high as (0.034 degrees C, 0.004 C) signal resolution to optimize temperature control. Using Tsic measurements is very simple, and it not only provides excellent accuracy, but also has long time stability. Because of its low power consumption (typically 30 A), it is also ideal for data recorders, digital thermometers, and temperature monitoring and measurement applications.
has the following advantages: high accuracy, precision can reach + 0.1 ~ C, measurement range from -50 to 150 DEG C, the measuring range is to maintain a high accuracy;
Tsic has a high price, IC has been calibrated test, users do not need to calibrate, have longer stability;
Tsic single bus output, simple interface, users can according to their own requirements for flexible application; the
Tsic series includes the standard 0 ~ 1V
analog output voltage and 11bit digital signal output mode, the user can choose according to their own needs;
Tsic using DSP technology, signal output rate can reach 0.1s output each time; the working current of the
Tsic is very low, low power consumption that is suitable for mobile devices;
wide operating voltage (3.0-5.5V), can work in a variety of power system, which makes the system design more flexible;
The TSic series temperature sensor IC is a low power specific design for automatic temperature sensing, measurement, industrial, medical / medical, and mobile applications in buildings.
TSic uses a high-precision reference source in proportion to absolute temperature (PTAT), integrates low-power, precision ADC and on-chip
DSP cores, and has an electrically erasable memory to accurately correct the output temperature signals.
TSic series temperature sensors are all tested and corrected, and the absolute accuracy of measurement can be obtained at the time of delivery. No further correction is required. Measuring temperature using TSic is very simple, and it can achieve outstanding accuracy and long term stability.
has an accuracy of + 0.1 DEG in the range of 40 C.

TSic protocol for ZACwire communication
ZACwire is a single line bidirectional communication protocol. Bit encoding is similar to the clock signal embedded in the data signal in the Manchester code (the falling edge of the signal is generated in fixed cycles). Thus, the protocol is insensitive to differences in baud rates between two IC communications.
In the end user application, the TSic transmits temperature information, and another IC (usually MCU) reads through the ZACwire
TSic temperature transfer package
TSic sends packets of 1 bytes in length. The package consists of 1 start bit, 8 data bits and a parity bit
A. The baud rate is 8kHz (125us interface). The signal is usually high when the transmission begins and the start signal is tight
Then there is the data bit (first, then low), and the end of the packet is the parity check bit.
TSic provides 11 bit resolution temperature data, and 11 bit data cannot be passed in a single package. One comes from TSic
The complete temperature transfer data package consists of 2 packages. The first package contains high 3 bit temperature information, and the second package contains low 8 bit temperature information. In the first packet transmission terminal and packet transmission between the second began to have a width of 1/2 bits (Bit Window) signal with high signal (stop).
