The STM8S003F3/K3 value line 8-bit microcontrollers offer 8 Kbytes of Flash program memory, plus integrated true data EEPROM. They are referred to as low-density devices in the STM8S microcontroller family reference manual (RM0016).
TheSTM8S003F3/K3 value line devices provide the following benefits: performance, robustness and reduced system cost.
Device performance and robustness are ensured by true data EEPROM supporting up to 100000 write/erase cycles, advanced core and peripherals made in a state-of-the-art technology at 16 MHz clock frequency, robust I/Os, independent watchdogs with separate clock source, and a clock security system.
The system cost is reduced thanks to a high system integration level with internal clock oscillators, watchdog, and brown-out reset.

风扇速度遥控板STEVAL-IHM037V1
The remote fan speed controller is a single channel TRIAC based solution meant to replacethe existing fan speed controllers and provide the IR remote control feature. It is designed tofit easily inside an enclosure with the dimensions of a single-switch module.A non-isolated capacitive power supply is used to power the microcontroller and the IR sensor. The TSOP38438 IR sensor is used to demodulate the 38 kHz IR signal from the IRtransmitter and decoded by the STM8S003 value line microcontroller to perform the variouscontrol functions. IR communication is based on the RC5 protocol standard. A TRIAC isused as the control element to regulate the power going into the fan by varying its firingangle for different speed settings. The speed settings can be changed by using the onboardtactile switches or by using the IR remote controller.
The STM8S003F3 value line 8-bit microcontroller, with its internal data EEPROM, hardwaretimers and external interrupts on GPIOs, makes an efficient implementation of theapplication possible while keeping the size, cost and external component count to aminimum.
