STEVAL-IHT005V1, Full 3.3V ACS/Triac Control Demonstration Board based on STM32 MCUs

STEVAL-IHT005V1, Demonstration Board is designed for the home appliance market, with a focus on the demonstration of a robust solution with 3.3V supplied 32-bit MCU. Targeted applications are mid-end and high-end washing machines, dishwashers and dryers with different kinds of ACS/Triacs. The demonstration board is based on the recently introduced 48-pin, 32-bit STM32F100C4T6B MCU running at 24 MHz (RC user-trimmable internal RC clock), featuring 16 Kbytes of Flash memory, 12-bit A/D converter, 5 timers, communication interfaces, and 4 Kbytes of SRAM. The power supply circuitry is based on the VIPer16L, an offline converter with an 800 V avalanche rugged power section, operating at 60 kHz. The power supply provides negative 6V in buck-boost topology
