Description
The Si7013 I2C Humidity and 2-Zone Temperature Sensor is a monolithic CMOS
IC integrating humidity and temperature sensor elements, an analog-to-digital
converter, signal processing, calibration data, and an I2C Interface. The patented
use of industry-standard, low-K polymeric dielectrics for sensing humidity enables
the construction of low-power, monolithic CMOS Sensor ICs with low drift and
hysteresis, and excellent long term stability.
The humidity and temperature sensors are factory-calibrated and the calibration
data is stored in the on-chip non-volatile memory. This ensures that the sensors
are fully interchangeable, with no recalibration or software changes required.
An auxiliary sensor input with power management can be tied directly to an
external thermistor network or other voltage-output sensor. On-board logic
performs calibration/linearization of the external input using user-programmable
coefficients. The least-significant bit of the Si7013's I2C address is programmable,
allowing two devices to share the same bus.
The Si7013 is available in a 3x3 mm DFN package and is reflow solderable. The
optional factory-installed cover offers a low profile, convenient means of
protecting the sensor during assembly (e.g., reflow soldering) and throughout the
life of the product, excluding liquids (hydrophobic/oleophobic) and particulates.
The Si7013 offers an accurate, low-power, factory-calibrated digital solution ideal
for measuring humidity, dew-point, and temperature, in applications ranging from
HVAC/R and asset tracking to industrial and consumer platforms.

Notes:
1. All values are referenced to VIL and/or VIH.
2. Depending on the conversion command, the Si7013 may hold the master during the conversion (clock stretch). At
above 300 kHz SCL, the Si7013 may hold the master briefly for user register and device ID transactions. At the highest
I2C speed of 400 kHz the stretching will be <50 μs.
3. Pulses up to and including 50 ns will be suppressed.
