description stm32f103xf, stm32f103xg 12/45 doc id 17144 rev 2 2.3 overview 2.3.1 arm ? cortex?-m3 core with embedded flash and sram the arm cortex?-m3 processor is the latest generation of arm processors for embedded systems. it has been developed to provide a low-cost platform that meets the needs of mcu implementation, with a reduced pin count and low-power consumption, while delivering outstanding computational performance and an advanced system response to interrupts. the arm cortex?-m3 32-bit risc processor features exceptional code-efficiency, delivering the high-performance expected from an arm core in the memory size usually associated with 8- and 16-bit devices. with its embedded arm core, stm32f103xf and stm32f103xg performance line family is compatible with all arm tools and software. figure 1 shows the general block diagram of the device family. 2.3.2 memory protection unit the memory protection unit (mpu) is used to separate the processing of tasks from the data protection. the mpu can manage up to 8 protection areas that can all be further divided up into 8 subareas. the protection area sizes are between 32 bytes and the whole 4 gigabytes of addressable memory. the memory protection unit is especially helpful for applications where some critical or certified code has to be protected against the misbehavior of other tasks. it is usually managed by an rtos (real-time operating system). if a program accesses a memory location that is prohibited by the mpu, the rtos can detect it and take action. in an rtos environment, the kernel can dynamically upd ate the mpu area setting, based on the process to be executed. the mpu is optional and can be bypassed for applications that do not need it. 2.3.3 embedded flash memory 768 kbytes to 1 mbyte of embedded flash are available for storing programs and data. the flash memory is organized as two banks. t he first bank has a size of 512 kbytes. the second bank is either 256 or 512 kbytes depending on the device. this gives the device the capability of writing to one bank while executing code from the other bank (read-while-write capability). 2.3.4 crc (cyclic redundanc y check) calculation unit the crc (cyclic redundancy check) calculation unit is used to get a crc code from a 32-bit data word and a fixed generator polynomial. among other applications, crc-based techniques are used to verify data transmission or storage integrity. in the scope of the en/iec 60335-1 standard, they offer a means of verifying the flash memory integrity. the crc ca lculation unit helps co mpute a signature of the software during runtime, to be compared with a reference signature generated at link- time and stored at a given memory location.
stm32f103xf, stm32f103xg description doc id 17144 rev 2 13/45 2.3.5 embedded sram 96 kbytes of embedded sram accessed (read/write) at cpu clock speed with 0 wait states. 2.3.6 fsmc (flexible static memory controller) the fsmc is embedded in the stm32f103xf and stm32f103xg performance line family. it has four chip select outputs supporting the following modes: pc card/compact flash, sram, psram, nor and nand. functionality overview: the three fsmc interrupt lines are ored in order to be connected to the nvic write fifo code execution from external memory except for nand flash and pc card the targeted frequency, f clk , is hclk/2, so external access is at 36 mhz when hclk is at 72 mhz and external access is at 24 mhz when hclk is at 48 mhz 2.3.7 lcd parallel interface the fsmc can be configured to interface seamlessly with most graphic lcd controllers. it supports the intel 8080 and motorola 6800 modes, and is flexible enough to adapt to specific lcd interfaces. this lcd parallel interface capability makes it easy to build cost- effective graphic applications using lcd modules with embedded controllers or high- performance solutions using external controllers with dedicated acceleration. 2.3.8 nested vectored interrupt controller (nvic) the stm32f103xf and stm32f103xg performance line embeds a nested vectored interrupt controller able to handle up to 60 maskable interrupt channels (not including the 16 interrupt lines of cortex?-m3) and 16 priority levels. closely coupled nvic gives low latency interrupt processing interrupt entry vector table address passed directly to the core closely coupled nvic core interface allows early processing of interrupts processing of late arriving higher priority interrupts support for tail-chaining processor state automatically saved interrupt entry restored on interrupt exit with no instruction overhead this hardware block provides flexible interrupt management features with minimal interrupt latency. 2.3.9 external interrupt /event controller (exti) the external interrupt/event controller consists of 19 edge detector lines used to generate interrupt/event requests. each line can be independently configured to select the trigger event (rising edge, falling edge, both) and can be masked independently. a pending register maintains the status of the interrupt requests. the exti can detect an external line with a pulse width shorter than the internal apb2 cloc k period. up to 112 gp ios can be connected to the 16 external interrupt lines.
description stm32f103xf, stm32f103xg 14/45 doc id 17144 rev 2 2.3.10 clocks and startup system clock selection is performed on startup, however the internal rc 8 mhz oscillator is selected as default cpu clock on reset. an ex ternal 4-16 mhz clock can be selected, in which case it is monitored for failure. if failure is detected, the system automatically switches back to the internal rc oscillato r. a software interrupt is genera ted if enabled. similarly, full interrupt management of the pll clock entry is available when necessary (for example with failure of an indirectly used external oscillator). several prescalers allow the configuration of the ahb frequency, the high speed apb (apb2) and the low speed apb (apb1) domains. the maximum frequency of the ahb and the high speed apb domains is 72 mhz. the maximum allowed frequency of the low speed apb domain is 36 mhz. see figure 2 for details on the clock tree. 2.3.11 boot modes at startup, boot pins are used to select one of three boot options: boot from user flash: you have an option to boot from any of two memory banks. by default, boot from flash memory bank 1 is selected. you can choose to boot from flash memory bank 2 by setting a bit in the option bytes. boot from system memory boot from embedded sram the boot loader is located in system memory. it is used to reprogram the flash memory by using usart1. 2.3.12 power supply schemes v dd = 2.0 to 3.6 v: external power supply for i/os and the internal regulator. provided externally through v dd pins. v ssa , v dda = 2.0 to 3.6 v: external analog power supplies for adc, reset blocks, rcs and pll (minimum voltage to be applied to v dda is 2.4 v when the adc is used). v dda and v ssa must be connected to v dd and v ss , respectively. v bat = 1.8 to 3.6 v: power supply for rtc, external clock 32 khz oscillator and backup registers (through power switch) when v dd is not present. 2.3.13 power supply supervisor the device has an integrated power-on reset (por)/power-down reset (pdr) circuitry. it is always active, and ensures proper operation starting from/down to 2 v. the device remains in reset mode when v dd is below a specified threshold, v por/pdr , without the need for an external reset circuit. the device features an embedded programmable voltage detector (pvd) that monitors the v dd /v dda power supply and compares it to the v pvd threshold. an interrupt can be generated when v dd /v dda drops below the v pvd threshold and/or when v dd /v dda is higher than the v pvd threshold. the interrupt service routine can then generate a warning message and/or put the mcu into a safe state. the pvd is enabled by software.
stm32f103xf, stm32f103xg description doc id 17144 rev 2 15/45 2.3.14 voltage regulator the regulator has three operation modes: main (mr), low power (lpr) and power down. mr is used in the nominal regulation mode (run) lpr is used in the stop modes. power down is used in standby mode: the regulator output is in high impedance: the kernel circuitry is powered down, inducing ze ro consumption (but the contents of the registers and sram are lost) this regulator is always enabled after reset. it is disabled in standby mode. 2.3.15 low-power modes the stm32f103xf and stm32f103xg performance line supports three low-power modes to achieve the best compromise between low power consumption, short startup time and available wakeup sources: sleep mode in sleep mode, only the cpu is stopped. all peripherals continue to operate and can wake up the cpu when an interrupt/event occurs. stop mode stop mode achieves the lowest power consumption while retaining the content of sram and registers. all clocks in the 1.8 v domain are stopped, the pll, the hsi rc and the hse crystal oscillators are disabled. the voltage regulator can also be put either in normal or in low-power mode. the device can be woken up from stop mode by any of the exti line. the exti line source can be one of the 16 external lines, the pvd output, the rtc alarm or the usb wakeup. standby mode the standby mode is used to achieve the lowest power consumption. the internal voltage regulator is switched off so that the entire 1.8 v domain is powered off. the pll, the hsi rc and the hse crystal oscillators are also switched off. after entering standby mode, sram and register contents are lost except for registers in the backup domain and standby circuitry. the device exits standby mode when an external reset (nrst pin), an iwdg reset, a rising edge on the wkup pin, or an rtc alarm occurs. note: the rtc, the iwdg, and the corresponding clock sources are not stopped by entering stop or standby mode. 2.3.16 dma the flexible 12-channel general-purpose dmas (7 channels for dma1 and 5 channels for dma2) are able to manage memory-to-memory, peripheral-to-memory and memory-to- peripheral transfers. the two dma controllers support circular buffer management, removing the need for user code intervention when the controller reaches the end of the buffer. each channel is connected to dedicated hardware dma requests, with support for software trigger on each channel. configuration is made by software and transfer sizes between source and destination are independent.
