2-deg-accurate I2C temperature sensor IC is under 1-mm-square
With a combination of tiny package and excellent temperature measurement accuracy, the chip has an I2C/SMBus-compatible serial interface that accepts standard write byte, read byte, send byte, and receive byte commands to read the temperature data and configure the behaviour of the sensor. Bus timeout resets the interface if the clock is low for more than 30 msec (nominal). PEC helps to avoid communication errors when used with a master that supports this feature.
In its 4-bump, wafer-level package (WLP) it operates over the -20°C to +150°C temperature range.
