RTC Wake Up Timer
The Wake Up Timer is more like an alarm, which wakes up and power on your
system at a pre-defined time for specific application. It can be set to wake up
everyday or on specific date within a month. The date/time accurate is second.
High Efficient Synchronous Switching Regulator
Most of the current switching designs are Asynchronous mode, which from the
technical point of view, still consumes very high power as well as heat. AX5T
implements high efficient synchronous switching design that the temperature of
MOS FET is less than 36 degree C compared with 57 degree Schottky diode of
Asynchronous design.
3V Over Current Protection Circuit
The Over Current Protection was very popular implemented on the Baby AT or
ATX +5V/+12V switching power supply. But unfortunately, the new generation
CPU and chipset use 3.3V or 2.8V voltage that have regulator to transfer 5V to
3.3V/2.8V, and make 5V over current protection useless. AX5T with switching
regulator onboard support 3.3V (Vcpuio, chipset, PBSRAM, SDRAM) and 2.8V
(CPU Vcore) over current protection, in conjunction with 5V/12V power supply
provide the full line over current protection.
CPU Thermal Protection
When CPU temperature is higher than 55 degree C, the CPU speed will
automatically slow down and there will be warning from BIOS and also ADM
(Advanced Desktop Manager, similar as Intel LDCM), if ADM is installed.
CPU Fan Monitoring
AX5T implements a fan monitoring function to prevent CPU overheat. The
system will report and alarm CPU fan malfunction either though BIOS or utility
software such as ADM (Advanced Desktop Manager).
System Voltage Monitoring
Further more, AX5T implements a voltage monitoring system, As you turn on
your system, this smart design will continue to monitor your system working
voltage. If any of the system voltage is over the component's standard. There
will be alarm through speaker or ADM (Advanced Desktop Manager) for a
warning to user.
FCC DoC certificate
AX5T is the first few boards to pass FCC DoC test. The radiation is very low, you
can use any kind of housing.
