MICROCHIP AT30TSE758A-XM8M-T

The AT30TSE752A/754A/758A are a complete, precise temperature monitoring device designed for use in a variety of applications that require the measuring of local temperatures as an integral part of the system's function and/or reliability. The AT30TSE752A/754A/758A devices combine a high- precision digital temperature sensor, programmable high and low temperature alarms, and a 2- wire I²C and SMBus (System Management Bus) compatible serial interface into a single, compact package. The temperature sensor can measure temperatures over the full - 55℃ to +125℃ temperature range and has a typical accuracy as precise as ±0.5℃ from 0℃ to +85℃. The result of the digitized temperature measurements are stored in one of the AT30TSE752A/754A/758A's internal registers, which is readable at any time through the device's serial interface. The AT30TSE752A/754A/758A utilizes flexible, user - programmable internal registers to configure the temperature sensor's performance and response to high and low temperature conditions. The device also contains a set of Nonvolatile Registers to retain the configuration and temperature limit settings even after the device has been power cycled, thereby eliminating the need for the de
