1.10 Structure and functioning
1.10.1 Processor
The device is based on a dual-core x86-compatible 32-bit Vortex86DX3 processor with low power
consumption, made using 45nm technology. The operating frequency of the processor is 800 MHz.
The detailed information on the processor, as well as the current versions of drivers and system
software can be found on the manufacturer's website at:
1.10.2 Supervisor, Watchdog, Reset
The device includes a power supply supervisor (a microchip that monitors the power supply
voltage of the device), as well as 2 watchdog timers integrated into the CPU (WDT0, WDT1). The
supervisor generates a hardware reset signal when the "3.3V" power supply voltage drops below
3.08 V.
The watchdog timer can be used to avoid software freeze-ups. The WDT0 and WDT1 watchdog
timers are triggered in the absence of software confirmations for 30.5
μs ... 512 sec. The internal
watchdog timer is started in the SYSTEM BIOS SETUP. It is possible to configure the actuation of
the internal watchdog timer with or without generation of a hardware reset signal.
The device is reset when the power is turned on, by software, as well as by pressing the "RESET"
button.
1.10.3 RAM
The device uses dynamic DDR3 SDRAM with a total size of 2 GB and operating at a frequency of
667 MHz as a system memory. The memory module cannot be expanded.
1.10.4 Non-volatile RAM
The
device has 8 KB of integrated non-volatile RAM made by FRAM technology and does not
require battery power. The SPI interface of the processor is used to access the non-volatile
memory.
