Atmel AT30TSE752/754/758 [DATASHEET]
8751C–DTS–6/12
1. Description
The Atmel® AT30TSE752/754/758 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 AT30TSE752/754/758 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°C to +125°C temperature range and has a typical
accuracy as precise as ±0.5°C from 0°C to +85°C. The result of the digitized temperature measurements are stored in
one of the AT30TSE752/754/758's internal registers, which is readable at any time through the device's serial interface.
The AT30TSE752/754/758 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 device to be reconfigured after each Power-up operation. This additional flexibility permits
the device to run self-contained and not rely upon a host controller for device configuration.
In addition, the AT30TSE752/754/758 contain a 2-Kbit, 4-Kbit, or 8-Kbit Serial EEPROM that can be used to store vital
user system configuration and preference data. This additional feature permits the device to replace an existing
2-wire I2C Serial EEPROM in an application saving board space and component cost.
A dedicated alarm output activates if the temperature measurement exceeds the user-defined temperature and fault
count limits. To reduce current consumption and save power, the AT30TSE752/754/758 features a Shutdown mode that
turns off all internal circuitry except for the internal Power-On Reset (POR) and serial interface circuits. The device can
also be configured to power-up in the Shutdown mode to ensure that the device remains in a low-power state until the
user wishes to perform temperature measurements.
The AT30TSE752/754/758 are factory-calibrated and requires no external components to measure temperature. With
it’s flexibility and high-degree of accuracy, the AT30TSE752/754/758 are ideal for extended temperature measurements
in a wide variety of communication, computer, consumer, environmental, industrial, and instrumentation applications.

In addition, the AT30TSE752/754/758 contain a 2-Kbit, 4-Kbit, or 8-Kbit Serial EEPROM (respectively) that could be
used to store critical user system configuration and preference data. This additional feature permits the device to replace
