Features SensorPath Bus 4 hardware programmable addresses Temperature Sensing 0.25 °C resolution 127.75 °C maximum temperature reading 8-lead MSOP package Description The LM95010 is a digital output temperature sensor that has single-wire interface compatible with National Semiconductor's SensorPath interface. It uses a [Delta]Vbe analog temperature sensing technique that generates a differential voltage that is proportional to temperature. This voltage is digitized using a Sigma-Delta analog-to-digital converter. The LM95010 is part of a hardware monitor system, comprised of two parts: the PC System Health Controller (Master), such as a Super I/O, and up to seven slaves of which four can be LM95010s. Using SensorPath, the LM95010 will be controlled by the master and report to the master its own die temperature. SensorPath data is pulse width encoded, thereby allowing the LM95010 to be easily connected to many general purpose micro-controllers. Key Specification Temperature Sensor Accuracy ±2 °C (max) Temperature Range -20 °C to +125 °C Power Supply Voltage +3.0V to +3.6V Power Supply Current 0.5 mA (typ) Conversion Time 14 ms to 1456 ms Applications Microprocessor based equipment (Motherboards, Base-stations, Routers, ATMs, Point of Sale, ...)

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
