Microchip's ?AT30TSE758A 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 AT30TSE758A combines precision temperature monitoring, nonvolatile (NVM) registers, and 8Kb of Serial EEPROM. 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 integrated Serial EEPROM is a drop in replacement for a standalone Serial EEPROM saving board space and reducing BOM costs. The Serial EEPROM can be used to store system configuration and vital product data.
The AT30TSE758A is factory calibrated and requires no external components to help provide a cost effective solution. 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. The AT30TSE758A is based on the industry standard "LM75-type" compatible temperature sensor and is a precision temperature monitoring device designed for use in a variety of applications. 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.
