1. Describe

The AT30TS74-MA8M-T is a complete, accurate temperature monitoring device designed for use in a variety of Applications that require local temperature measurement as an integral part of system functionality and/or reliability. The AT30TS74 device incorporates a high-accuracy digital temperature sensor, programmable High and low temperature alarms, and 2-wire I2C and SMBus (system management bus) compatible serial interface into a compact package. The temperature sensor can measure temperatures over the entire -55°C to +125°C temperature range and has -20°C to +100°C has a maximum accuracy of ±2.0°C. The result of the digitized temperature measurement is Stored in one of the AT30TS74 internal registers and can be read at any time via the device's serial interface. The AT30TS74 utilizes flexible, user-programmable internal registers to configure the temperature sensor Performance and response to high and low temperature conditions. A dedicated alarm output activates if Temperature measurement exceeds user-defined temperature and fault count limits. reduce current To consume and save power, the AT30TS74 has a shutdown mode that shuts down all internal circuits Except for the internal power-on reset (POR) and serial interface circuitry. The AT30TS74 is factory calibrated to measure temperature without external components.
