Product Overview
The M601B, M1601B, and M1820B series are digital-analog mixed-signal temperature sensor chips from Mysentech. These chips offer high measurement accuracy up to 0.5C without requiring user calibration. Leveraging CMOS semiconductor PN junction temperature and bandgap voltage characteristics, they provide high precision, good consistency, fast temperature sensing, low power consumption, flexible programmable configuration, and long lifespan. With a built-in 16-bit ADC, they achieve a resolution of 0.004C and operate across an ultra-wide temperature range of -70C to +150C. Each chip features a unique 64-bit ID serial number, factory tested and calibrated. The single-bus digital interface simplifies system integration, requiring only one GPIO port for communication with a host microcontroller. This enables cost-effective, distributed sensing networks supporting up to 100 nodes over distances of 100 to 500 meters. Integrated non-volatile E2PROM stores chip ID, alarm thresholds, calibration coefficients, and user-defined information. The M601B model includes an ALERT pin for hardware alarm indication.
