Miscellaneous

Real Time Clock (RTC) 

The MightyBoard 821 contains a Real Time Clock (RTC). The CMOS RAM is backed up with a Lithium 

Battery. If the battery is not present, the BIOS has a battery-free boot option to complete the boot process. 

External Battery (BT1)

An external battery input connection is provided through the battery connector (BT1) for an external battery. 

The external battery is used to power the Real Time Clock. Ampro provides a small Lithium Battery, taped 
to the Super I/O (U5) with adhesive tape, and connected to the external battery connection (BT1). This small 

external Lithium battery serves as an on-board battery. 

Temperature Monitoring 

The Super I/O chip (W83627HF) performs the temperature monitoring function. The inputs to the Super 

I/O chip come from the thermal diode in the Intel Celeron M or Pentium M CPU and a single thermistor 
(RT2) on the underside of the MightyBoard near pin 4 of the Infrared (IrDA) connector (J7). 

User GPIO Signals (J8)

The MightyBoard 821 provides ten GPIO pins, including power and ground, for custom use, and the signals 

are routed to the J8 connector. Enable and initialize values are set in the BIOS. An example of how to use the 
GPIO pins resides in the Miscellaneous Source Code Examples on the MightyBoard 821 Support Software 

DVD.

The example program can be built by using the 

make.bat

 file. This produces a 16-bit DOS executable 

application, 

gpio.exe

, which can be run on the MightyBoard 821 to demonstrate the use of GPIO pins. For 

more information about the GPIO pin operation, refer to the Programming Manual for the Super I/O 

(W83627HF) controller at: 

http://www.nuvoton-usa.com/products/winbond_products/pdfs/PCIC/W83627HF_HGb.pdf

Note:

The shaded area denotes power or ground. 

NOTE

The MightyBoard 821 requires a heatsink with a fan for both CPU versions (Intel 
Celeron M or Pentium M) and the Memory Hub (Northbridge).
