The STEVAL-CBP006V1 UniPower 
demonstration board is designed to provide a 
ready-to-use platform for power supply 
management and user-interface control 
developed around the STM8S MCU. The board 
can manage various wakeup sources, and 
perform power supply switching of the rest of the 
application during standby. The board also 
features an ST capacitive touch-sensing software 
library capable of turning any 8-bit STM8 
microcontroller into a capacitive touch-sensing 
controller.

         

The UniPower demonstration board is 
preprogrammed with demonstration firmware to 
manage most of the system’s hardware 
resources, such as digital and analog I/Os, LEDs 
and mechanical buttons. Touch-sensing functions 
can thus be easily combined with traditional MCU 
capabilities by selecting appropriate modules 
from the UniPower MCU firmware library. The 
UniPower demonstration board allows designers 
who are familiar with the use of standard 
microcontrollers to perform extensive application 
standby power management and create higher-
end look-and-feel human interfaces by replacing 
conventional electromechanical switches with 
capacitive touchkeys. The application cost can be 
reduced by choosing a smaller MCU from the 
STM8S portfolio. The board is delivered with a 
SWIM interface, allowing adaptation of the 
firmware to application requirements. This 
simplifies the concept of the UniPower MCU 
firmware library, and makes the evaluation of the 
key features for end-applications easy. Maturity, 
robustness, flexibility and performance make this 
solution simple to implement and quick to market. 
It can be integrated into various types of 
consumer application, such as set-top boxes, 
digital TVs and home appliances. For further 
details about the touch-sensing software library, 
please refer to the STM8 touch-sensing firmware 
documentation.
