【正文】 3xx microcontroller with an embedded ARM core, so can be patible with all ARM tools and software. 4 2. Embedded Flash memory and RAM memory: builtup to 512KB embedded Flash, can be used to store programs and data. Up to 64KB of embedded SRAM can read and write to the clock speed of the CPU (not wait state). 3. A variable static memory (FSMC): FSMC embedded in STM32F103xC, STM32F103xD, STM32F103xE, with four chip select support four modes: Flash, RAM, PSRAM, NOR and NAND. After OR after three FSMC interrupt lines connected to the NVIC. No read / write FIFO PCCARD outside, the code is executed from the external memory, and does not support the Boot took target frequency equal to SYSCLK / 2 Therefore, when the system clock is 72MHz, external access, according to 36MHz. 4. Nested vector interrupt controller (NVIC): can handle 43 maskable interrupt channels (not including the 16 interrupt lines of CortexM3), provides 16 interrupt priority. Tightly coupled NVIC lower interrupt processing delay directly passed to the kernel interrupt entry vector table address, tightly coupled the NVIC kernel interface, allows interrupts to be anticipated, after the higherpriority interrupt handling support tail chain, automatically save the state of the processor, interrupt entry automatically resume when the interrupt exit, no instruction intervention. 5. The external interrupt / event controller (EXTI): External interrupt / event controller for 19 to generate an interrupt / event request edge detector lines. Each line can be individually configured to select the trigger event (rising edge, falling edge, or both), can also be individually shielded, a pending register to maintain the state of the interrupt request. When the external line appear longer than internal APB2 clock cycle pulse, EXTI is able to detect. Up to 112 GPIO connected to the 16 external interrupt lines. 6. Clock and start: start or system clock selection, but reset when the internal 8MHz crystal was selected as the CPU clock. Can select one of 416MHz external clock, and will be monitored to determine whether successful. During this period, the controller is disabled and the software interrupt management subsequently also be prohibited. At the same time, if there is a need (for example, encountered an indirect use of crystal failed), PLL clock interrupt management fully available. Multiple preparator can be used to configure the AHB frequency, including highspeed APB (PB2) and lowspeed APB (APB1), highspeed APB highest frequency of 72MHz, lowspeed APB highest frequency of 36MHz. 7. Boot mode: startup, Boot pin is used to select one of three kinds Boot Options kinds: Import from user Flash memory from the system import, import from SRAM. The Boot import program is located in the system memory for Flash Memory Programming by USART1 re. 8. Power supply program: VDD voltage range of , VDD pin provides an external power supply through, for I / O and internal regulator. VSSA and VDDA, voltage range of , external analog voltage input for the ADC reset module, RC and PLL VDD range (ADC is limited to )。 Cortex ?
