Product Introduction

Digital temperature sensor chip - M601B, M1601B, M1820BSeries isDigitalAnalog mixed-signal temperature sensor chip,relativelyMaximum temperature measurement accuracy of 0°CIn the range up to 50°C ±0.5°C, no user calibration required.The temperature sensing principle of the temperature chip is based on the relationship between CMOS semiconductor PN junction temperature andThe characteristic relationship of bandgap voltage, after small-signal amplification, analog-to-digital conversion,Digital calibration and compensation, then digital bus output, with high accuracy, goodGood consistency, fast temperature measurement, low power consumption, flexible programmable configuration, longLong lifespan, etc.

The temperature chip has a built-in 16-bit ADC with a resolution of 0.004°C andUltra-wide operating range from -70°C to +150°C. The chip has a unique 64-Unique ID serial number, 100% tested and calibrated before leaving the factory, withCalibration coefficient fitting based on temperature error characteristics, with internal self-Automatic compensation calculation. To simplify system application, the chip's ID searchSearch, temperature data memory access, function configuration, etc., are all based on digital singleBus protocol commands, the host microprocessor only needs one GPIOPort for read and write access. The single-bus communication interface sharesA single data bus to achieve low-cost multi-node sensor acquisition and networkingThis solution has long transmission distance, supports many nodes, and facilitates spatial distributionDistributed sensor networking.relativelySupports up to 100 nodes, 100 to 500Meter-long temperature measurement node serial networking.

Built-in non-volatile E2PROM storage unit for saving chipID number, high and low temperature alarm thresholds, temperature calibration correction values, and userUser-defined information, such as sensor node number, location information, etc.M601B also has an ALERT alarm indication pin for user expansionHardware alarm applications.
