Microchip Technology AT30TSE758A Digital Temperature Sensors

Microchip Technology AT30TSE758A Digital Temperature Sensors are complete and precise temperature monitoring devices. These temperature sensors use flexible and user-programmable internal registers to configure sensor performance and response to high and low-temperature conditions. The temperature monitoring devices contain non-volatile registers to retain the configuration and temperature limit settings. The AT30TSE758A temperature sensors have a 2-wire I²C and System Management Bus (SMBus) compatible serial interface in a single and compact package. These digital sensors feature 2Kb, 4Kb, or 8Kb serial EEPROM that can store vital user system configuration and preference data. Typical applications include extended temperature measurements in various communication, computer, consumer, environmental, industrial, and instrumentation.
