Features Core: ARM 32-bit Cortex™-M3 CPU 72 MHz, 90 DMIPS with 1.25 DMIPS/MHz Single-cycle multiplication and hardware division Memories 32-to-512 Kbytes of Flash memory 6-to-64 Kbytes of SRAM Low power Sleep, Stop and Standby modes VBAT supply for RTC and backup registers Up to 9 communication interfaces Up to 3 USARTs (ISO 7816 interface, LIN, IrDA capability, modem control) Up to 2 SPIs (18 Mbit/s) CAN, I2C interfaces USB 2.0 full speed interface STM32 소개 3

STM32 key benefits Leading-edge architecture with Cortex-M3 core Harvard architecture 1.25 DMIPS/MHz and 0.19 mW/MHz Thumb-2 instruction set brings 32-bit performance with 16-bit code density Single cycle multiply and hardware division Embedded, fast interrupt controller is now inside the core allowing: Excellent real-time behavior Low latency down to six CPU cycles inter-interrupt Six CPU cycles wake-up time from low-power mode Up to 35% faster and up to 45% less code than ARM7TDMI® STM32 소개 4

Cortex-M3 interrupt versus ARM7TDMI STM32 소개 6

Outstanding power efficiency High performance does not mean high power consumption –Current consumption as low as 27 72MHz The STM32 has three different low-power modes Sleep mode (Cortex-M3 core stopped, peripherals kept running) Stop mode (all clocks are stopped) Standby mode (1.8v domain powered-off) Auto-wakeup (AWU) from low-power mode The RTC can be used to wakeup the MCU from low-power mode STM32 소개 7

High level of integration Built-in supervisor reduces need for external components: Power-on reset, low-voltage detect, brown-out detect, watchdog timer with independent clock One main crystal drives entire system: Inexpensive 4-16 MHz crystal drives CPU, USB and all peripherals Embedded PLL generates multiple frequencies Optional 32 kHz crystal for RTC Embedded factory trimmed 8 MHz RC oscillator can be used as main clock Only 7 external passive components required for base system on LQFP100 package STM32 소개 8
