The AT30TS750 device combines 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 AT30TS750's internal registers, which is readable at any time through the device's serial interface. The AT30TS750 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. 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 AT30TS750 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 AT30TS750 is factory-calibrated and requires no external components to measure temperature. With it’s flexibility and high-degree of accuracy, the AT30TS750 is ideal for extended temperature measurements in a wide variety of communication, computer, consumer, environmental, industrial, and instrumentation applications. Atmel AT30TS750 [DATASHEET] Pin Descriptions and Pinouts Table Pin Description Symbol Name and Function Asserted State Type Serial Clock This pin is used to provide a clock to the device and is used to control the flow of data to and from the device. Command and input data present on the SDA pin is always latched in on the rising edge of SCL, while output data on the SDA pin is always clocked out on the falling edge of SCL. The SCL pin must either be forced high when the serial bus is idle or pulled-high using an external pull-up resistor. Input Serial Data The SDA pin is an open-drain bidirectional input/output pin used to serially transfer data to and from the device. The SDA pin must be pulled-high using an external pull-up resistor and may be wire-ANDed with any number of other open-drain or open-collector pins from other devices on the same bus. Input/Output ALERT Alert The ALERT pin is an open-drain output pin used to indicate when the temperature goes beyond the user-programmed temperature limits. The ALERT pin can be operated in one of two different modes Interrupt or Comparator mode as defined by the CMP/INT bit in the Configuration Register. The ALERT pin defaults to an active-low output upon device power-up or reset but can be reconfigured as an active-high output by setting the POL bit in the Configuration Register. This pin can be wire-ANDed together with ALERT pins from other devices on the same bus. When wire-ANDing pins together, the ALERT pin should be configured as an active-low output so that when a single ALERT pin on the common alert bus goes active, the entire common alert bus will go low and the host controller will be properly notified since other ALERT pins that may be in the inactive-high state will not mask the true alert signal. In an SMBus environment, the SMBus host can respond by sending an SMBus ARA Alert Response Address command to determine which device on the SMBus generated the alert signal. The ALERT pin must be pulled-high using an external pull-up resistor even when it is not used. Care must also be taken to prevent this pin from being shorted directly to ground without a resistor at any time whether during testing or normal operation.
