STEVAL-IAS003V1

STEVAL-IAS003V1 counter demonstration board is intended as an example for applications where a directly driven LCD with the associated programmable functionality is needed. The application is focused on low power consumption, so the STM8L101xx MCU is used, and software is written to optimally use the low power modes available. This results in an average current consumption for the entire application of below 1.5uA, including direct LCD drive, implemented by software. Very low consumption is achieved by keeping the microcontroller in the active halt low power mode for most of the time. From this mode, the STM8L101xx is awakened regularly by the auto wake up timer.

• 1.6uA consumption at 18Hz refresh rate
• 3 digit LCD glass driven by software
• 2 buttons
• CR1220 battery operated
• Minimum external components
• Low cost PCB
