Biscotti Step Counter
A Collaboration Between Future Electronics and STMicroelectronics
Biscotti is a step counter demonstration board designed by Future Electronics in partnership with ST Micro. It features ST Micro’s Ultra-low-power Arm Cortex-M0+ MCU (STM32L031G6U6) with 32-Kbytes of Flash memory and a 3-axis ultra-low-power MEMS accelerometer (ST Micro’s LIS2DS12) that detects step movement.
The Biscotti step counter is powered by a CR2450 with ST Micro’s L6920DB synchronous step up converter and LD39020 low quiescent current LDO. If no movement for 15 second, the device will go into sleep mode.
