15.4. Filter
Parameter
FILTER
Value
0, 1, 2
The MLX90367 features a filter that is enabled when FILTER = 1 or 2.
The filter is of type “moving average”. It averages the two most recent internal angle values in case
FILTER=1 and the four most recent internal angle values in case FILTER=1
When the filter is enabled, the SENT data holds the average of the two or 4 most recent internal angles.
We recommend to enable the filter, in order to benefit from a noise reduction of 30% compared to the
case FILTER = 0. Given that two angle values are computed per each SENT frame, the latency increases
in this case only marginally.
Filter = 0 corresponds to no filtering, and may be selected to optimize the latency (by about 10%),
whenever the latter is system-critical (e.g. stability of a close-loop system).
15.5. Diagnostic Features
Refer to Application_note_Diagnostic_Behavior_90367 for EE_CRC_Enable function description and for
Diagnostic features which can be enabled at user.
It is recommended to enable the diagnostic features for safety critical applications.
15.6. EEPROM endurance
Although the EEPROM is used for Calibration Data Storage (similarly to an OTPROM), the MLX90367
embedded EEPROM is qualified to guarantee an endurance of minimum 1000 write cycles at 125˚C for
(engineering/calibration purpose).
