ST STM8S103F2 8位MCU马达驱动方案ST公司的STM8S103F2/x3是集成了8KB闪存程序存储器和数据EEPROM,内核工作频率16MHz,具有哈佛架构和3级流水线和扩展指令集,工作电压2.95 到5.5 V,主要用在真空吸尘器,食物处理机和电动工具.本文介绍了STM8S103F2/x3主要特性,框图,评估板STEVAL-IHM029V2主要特性,框图,电路图,材料清单和PCB设计文件图.The STM8S103F2/x3 access line 8-bit microcontrollers offer 8 Kbytes Flash program memory, plus integrated true data EEPROM. The STM8S microcontroller family reference manual (RM0016) refers to devices in this family as low-density. They provide the following benefits: performance, robustness, and reduced system cost.Device performance and robustness are ensured by advanced core and peripherals made in a state-of-the art technology, a 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 an integrated true data EEPROM for up to 300 k write/erase cycles and a high system integration level with internal clock oscillators, watchdog and brown-out reset.STM8S103F2主要特性:Core 16 MHz advanced STM8 core with Harvard architecture and 3-stage pipeline Extended instruction setMemories Program memory: 8 Kbytes Flash; data retention 20 years at 55 after 10 kcyclesData memory: 640 bytes true data EEPROM; endurance 300 kcyclesRAM: 1 KbytesClock, reset and supply management 2.95 to 5.5 V operating voltage Flexible clock control, 4 master clock sources Low power crystal resonator oscillator External clock input Internal, user-trimmable 16 MHz RC Internal low-power 128 kHz RC Clock security system with clock monitor Power management: Low-power modes (wait, active-halt, halt) Switch-off peripheral clocks individually Permanently active, low consumption power-on and power-down resetInterrupt management Nested interrupt controller with 32 interrupts Up to 27 external interrupts on 6 vectorsTimersAdvanced control timer: 16-bit, 4 CAPCOM channels, 3 complementary outputs, dead-time insertion and flexible synchronization16-bit general purpose timer, with 3 CAPCOM channels (IC, OC or PWM) 8-bit basic timer with 8-bit prescalerAuto wake-up timer Window watchdog and independent watchdog timersCommunication interfaces SPI interface up to 8 Mbit/s UART with clock output for synchronous operation, SmartCard, IrDA, LIN master mode I2C interface up to 400 kbit/sAnalog to digital converter (ADC) 10-bit, 1 LSB ADC with up to 5 multiplexed channels, scan mode and analog watchdog I/OsUp to 28 I/Os on a 32-pin package including 21 high sink outputs Highly robust I/O design, immune against current injectionUnique ID 96-bit unique key for each device图1.STM8S103F2/x3框图评估板STEVAL-IHM029V2The STEVAL-IHM029V2 is a low-cost universal motor control evaluation board designed for the home appliance market, with particular focus on vacuum cleaners, food processors and power tools. This system features the 20-pin, 8-bit STM8S103F2 microcontroller running at 16 MHz (user-trimmable internal RC clock), featuring 4 KB of Flash memory, a 10-bit A/D converter, 8/16 bit timers, communication interfaces and 640 bytes of E2PROM. The power supply circuitry features the VIPer16L, an off-line converter with an 800 V avalanche-rugged power section, operating at 60 kHz.The STEVAL-IHM029V2 especially targets vacuum cleaner applications with power up to 900 W and fulfills the requirements of the 2009/125/EC EU directive, applicable starting in September 2017, thanks to the T1235T, a 12 A 800 V high performance Triac. The motor control is based on phase-angle.In order to limit in-rush current and possible current peaks, the evaluation board features a soft-start routine and a smooth power change function. The board passed the pre-compliance tests for EMC directives IEC 61000-4-4 (burst up to 8 kV) and IEC 61000-4-5 (surge up to 2 kV). In standby mode, the STEVAL-IHM029V2 has an overall power consumption below 300 mW.图2.评估板STEVAL-IHM029V2外形图评估板STEVAL-IHM029V2主要特性:Input voltage range: 90-265 VAC, 50/60 Hz12 VDC / 5 VDC auxiliary power supply based on the VIPer16L in buck converter topologyTotal power consumption below 300 mW in standby modeMaximum output power: 1500 W20-pin, 8-bit STM8S103F2 MCU as main controllerEmploys zero-voltage switching (ZVS) to synchronize MCU events with the voltage mainsMotor driven by T1235T Triac in phase-angle control5 power levels and standby mode selectable by potentiometer5 LEDs to display the power level of the board“RUN” LED to indicate the board is functioningStandard in-circuit programming connectorIEC 61000-4-4 pre-compliance test passed (burst up to 8 kV)IEC 61000-4-5 pre-compliance test passed (surge up to 2 kV)RoHS compliantThe STEVAL-IHM029V2 universal motor control evaluation board is mainly targeted at thedomestic appliance market, including: Vacuum cleaners the new 2009/125/EC directive requires decre
