The MC68HC908QY4 has an internal oscillator circuit
which can generate a clock of 12.8 MHz with no external
components needed. The auto wakeup module generates
a periodic interrupt during stop mode to wake the part up
without requiring an external signal. These features make
the MC68HC908QY4 MCU suited for wireless optical mouse
applications.
The features of the MC68HC908JB12 include a configu-
rable universal serial bus (USB), which makes this MCU
suited for personal computer human interface devices
(HID) applications, such as mice. The enhanced timer

function also allows it to capture and decode data easily,
especially for high data rate wireless HID applications.
This kit is connectable to a PC via the USB port. It is also
based on the 27 MHz RF technology, the data generated
from displacement detection/button status in the optical
mouse is encoded with a pre-defined serial type protocol
handled by firmware in the MCU. In the RF stage, the en-
coded data is used for FSK modulation. The captured data
from the RF receiver stage is decoded with a correspond-
ing packet format used for mouse applications. The final
data is sent to the host through the USB interface.
