17.7. Hysteresis FILTER
Parameter
FHYST
Value
0 … 255
Note
1 LSB = 0.044 deg
The FHYST parameter is a hysteresis filter. The output value of the IC is not updated when the digital step
is smaller than the programmed FHYST parameter value. The output value is modified when the
increment is bigger than the hysteresis. The hysteresis filter reduces the resolution to a level compatible
with the internal noise of the IC. The hysteresis must be programmed to a value close to the noise level.
17.8. EMC Filter on SCI Pins
The EEPROM parameter PINFILTER selects the level of filtering on the serial protocol input pins.
SCI clock frequency
2MHz
1MHz
500kHz

17.9. Identification & FREE bytes
Parameter
USERID
FREE
Value
0..(2³¹-1)
0…(2³⁹-1)
Unit
Identification number: 32 bits freely useable by Customer for traceability purpose.
The FREE bytes can also be used for identification or any other purposes.
17.10. Lock
The calibration parameters of the MLX90363 are locked.
To unlock the write, one must follow the write procedure described in section 14.17.
