The M601, M1601, and M1820 series are high-precision digital-analog mixed-signal temperature sensor chips offering up to 0.1 accuracy without user calibration. Utilizing CMOS semiconductor PN junction temperature and bandgap voltage characteristics, these chips provide fast, low-power, and long-lasting temperature sensing with a wide operating range of -70C to +150C. Featuring a 16-bit ADC with 0.004C resolution, each chip has a unique 64-bit ID for factory calibration and automatic compensation. The single-bus protocol simplifies system integration, requiring only one GPIO port for communication and enabling cost-effective, scalable sensor networks with support for up to 100 nodes over 100-500 meters. Integrated non-volatile E2PROM stores ID, alarm thresholds, calibration values, and user-defined information. The M601 series also includes an ALERT pin for hardware alarm indication.
