Microchip's AT30TS750A temperature sensor requires a single 1.7V to 5.5V supply. To reduce current consumption and save power, the device features a shutdown mode which turns off all internal circuitry except for the internal power-on reset and serial interface circuits. In addition, the device features a power saving one-shot mode that allows the device to make a temperature measurement and update the temperature register and then return to shutdown mode. As a result, it can achieve a very low Operating Current of 150µA. The AT30TS750A combines precision temperature monitoring and nonvolatile (NVM) registers. The value-added NVM registers allow user configuration settings to be permanently retained across power cycles to simplify the system design, reduce processor startup code, and improve system reliability. The device is factory calibrated and requires no external components to help provide a cost effective solution. The device combines a highly accurate digital temperature sensor with programmable high and low temperature alarms, user-selectable resolution up to 12 bits, and an I²C/SMBus compatible serial interface available in compact packages. The temperature sensor is capable of measuring and converting temperatures from -55ºC to +125ºC to a digital word and provides a typical accuracy of ±0.5ºC over the operating temperature range of 0ºC to +85ºC. The AT30TS750A is pin and software compatible with industry standard "LM75-type" and is a precision temperature monitoring device designed for use in a variety of applications.
