The COP8SAC7 microcontroller can be used to cost-effectively provide a solution for a
laptop keyboard. With only a few passive components, the device can accomplish the
complete keyboard scan function. The same principles can be applied to all types of
keyboards (i.e. desktop keyboards) or data input devices. With low power consumption
being the most important design criteria, the device offers the power saving Multi-Input
Wakeup mode.
