1) NOTICE: LCD Display luminosity typically 1000 cd/m2, with touchpanel the
luminosity is 900 cd/m2
2) NOTICE: Frame rate depends on required performance in final application, this
value describes more of the HW capability.
3) NOTICE: Operating temperature can affect the display response time, especially in
a cold environment. This shall be considered in application development.
4.8. Internal features & diagnostics
4.8.1. Acceleration sensor
There is an internal 3-axis acceleration sensor with an acceleration range of ± 8 g max
and sample rate of 10 Hz. This sensor can be used for example tilt sensing purposes by
the application.
4.8.2. Supply supervision & voltage measurement
Pro Display has internal monitoring for a module’s internal power supplies. This is
implemented with a dedicated microcontroller that supervises a module’s internal
voltages.
It handles internal supplies for the start-up and shut-down procedures during boot-up
and shutdown. Power failure mode is applied in such cases where some of the internal
supplies are out of range.
4.8.3. Real time clock
This product has a real time clock (RTC) with back-up supply. The RTC is able to
maintain time settings for several days. The accuracy of the RTC is better than 25
seconds / day over full operating temperature range.
Back-up supply for the RTC is a maintenance-free power source.
The RTC has a programmable alarm interrupt output for waking the product up from
sleep. The interruption can be either an alarm or a specific time.
4.8.4. EEPROM
Pro Display comes with 32kB EEPROM memory. This memory is primarily intended for
device production information and is available only in read-only form for the application.
