3.2 Real-Time Clock
The board includes a real-time clock connected to the processor as a system RTC.
The RTC has an accuracy of approximately 1.7 seconds/day (11 minutes/year) at
25°C.
For data retention during power off the RTC is backed up by a supercapacitor. The
supercapacitor gives an autonomy of up to 72 hours when fully loaded.
The real-time clock device is connected to the CPU via SMBus. Due to its reduced
current consumption, the life time of the battery or supercapacitor can be increased
considerably compared to the RTC integrated in the CPU.
3.3 Processor Core
The BC50R can be equipped with several dual-core AMD APUs (Accelerated
Processing Units). The default APU is the T48N (marked in gray in the following
table).
Table 2. Processor core options on BC50R
MEN provides a dedicated software driver for the RTC device in order to
set date and time as usual in Windows. For a detailed description of the
functionality of the driver and for downloading the software please refer
to the drivers' documentation on MEN’s
website .
