Descriptions
The HP206C employs a MEMS pressure sensor with an I2C
interface to provide accurate Temperature, Pressure or Altitude
data. The sensor Pressure and Temperature outputs are digitized
by a high resolution 24-bit ADC. The Altitude value is calculated
by a specific patented algorithm according to the pressure and
temperature data. Data compensation is integrated internally to
save the effort of the external host MCU system. Easy
command-based data acquisition interface and programmable
interrupt control is available. Typical active supply current is 5.3
uA per measurement-second while the ADC output is filtered and
decimated by 256. Pressure output can be resolved with output in
fractions of a Pascal, and Altitude can be resolved in 0.01 meter.
The HP206C is offered in a 6.8 mm x 6.2 mm x 0.635(+0.2) mm
package and specified for operation from -40°C to 85°C.
Primary version. Do not guarantee all parameters.

5. Control Registers
The control registers allow the user to set the threshold 
values for various event detections, configure the 
interrupt setting, and enable/disable the data 
compensation. It is recommended for the user to set 
these registers to the desired values before performing 
the conversions or any other commandbased 
operations. The following is a table of all the control 
registers. 
 
 
 
 
 
 
The registers from 0x00 to 0x0A are designed for the 
user to setup the parameters (offset and thresholds) for 
pressure (or altitude) and temperature event 
detections. The registers from 0x0B to 0x0D are used for 
interrupt controls. The register of 0x0E is dedicated for 
switching on/off the sensor output compensation 
function inside the device.
