AT30TSE752A/754A/758A [DATASHEET]

Atmel-8854G-DTS-AT30TSE752A-754A-758A-Datasheet_102014

Description

The Atmel

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 I

C 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 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 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 AT30TSE752A/754A/758A contain a 2Kb, 4Kb, or 8Kb 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 I

C 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 AT30TSE752A/754A/758A 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 AT30TSE752A/754A/758A are factory-calibrated and requires no external components to measure temperature.

With its flexibility and high-degree of accuracy, the AT30TSE752A/754A/758A are ideal for extended temperature

measurements in a wide variety of communication, computer, consumer, environmental, industrial, and instrumentation

applications.
