Some system peripherals listed below are also provided byCortex™-M3:⏹Internal Bus Matrix connected with I-Code bus, D-Code bus, System bus, PrivatePeripheral Bus (PPB) and debug accesses.⏹Nested Vectored Interrupt Controller (NVIC).⏹Flash Patch and Breakpoint (FPB).⏹Data Watchpoint and Trace (DWT).⏹Instrumentation Trace Macrocell (ITM).⏹Embedded Trace Macrocell (ETM).⏹Serial Wire JTAG Debug Port (SWJ-DP).⏹Trace Port Interface Unit (TPIU).⏹Memory Protection Unit (MPU).3.2. On-chip memory⏹Up to 3072 Kbytes of Flash memory⏹Up to 96 Kbytes of SRAMThe ARM®Cortex™-M3 processor is structured in Harvard architecture which can useseparate buses to fetch instructions and load/store data. 3072 Kbytes of inner Flash and 96Kbytes of inner SRAM at most is available for storing programs and data, both accessed (R/W)at CPU clock speed with zero wait states.The Table 2-4. GD32F103xx memory mapshows the memory map of the GD32F103xx series of devices, including code, SRAM,peripheral, and other pre-defined regions.3.3. Clock, reset and supply management⏹Internal 8 MHz factory-trimmed RC and external 4 to 16 MHz crystal oscillator⏹Internal 40 KHz RC calibrated oscillator and external 32.768 KHz crystal oscillator⏹Integrated system clock PLL⏹ 2.6 to 3.6 V application supply and I/Os⏹Supply Supervisor: POR (Power On Reset), PDR (Power Down Reset), and low voltagedetector (LVD)The Clock Control unit provides a range of frequencies and clock functions. These include anInternal 8M RC oscillator (IRC8M), a High Speed crystal oscillator (HXTAL), a Low SpeedInternal 40K RC oscillator (IRC40K), a Low Speed crystal oscillator (LXTAL), a Phase LockLoop (PLL), a HXTAL clock monitor, clock prescalers, clock multiplexers and clock gatingcircuitry. The frequency of AHB, APB2 and the APB1 domains can be configured by eachprescaler. The maximum frequency of the AHB, APB2 and APB1 domains is 108 MHz/108MHz/54 MHz. See Figure 2-8. GD32F103xx clock tree for details.GD32F10x Reset Control includes the control of three kinds of reset: power reset, systemreset and backup domain reset.The system reset resets the processor core and peripheralIP components except for the SW-DP controller and the Backup domain.Power-on reset(POR) and power-down reset (PDR) are always active, and ensures proper operation startingfrom/down to 2.6 V. The device remains in reset mode when V DD is below a specifiedthreshold. The embedded low voltage detector (LVD) monitors the power supply, comparesit to the voltage threshold and generates an interrupt as a warning message for leading theMCU into security.Power supply schemes:⏹V DD range: 2.6 to 3.6 V, external power supply for I/Os and the internal regulator.Provided externally through V DD pins.⏹V SSA, V DDA range: 2.6 to 3.6 V, external analog power supplies for ADC, reset blocks,RCs and PLL. V DDA and V SSA must be connected to V DD and V SS, respectively.⏹V BAT range: 1.8 to 3.6 V, power supply for RTC, external clock 32 KHz oscillator andbackup registers (through power switch) when V DD is not present.3.4. Boot modesAt startup, boot pins are used to select one of three boot options:⏹Boot from main flash memory (default)⏹Boot from system memory⏹Boot from on-chip SRAMThe boot loader is located in the internal boot ROM memory (system memory). It is used toreprogram the Flash memory by using USART0 (PA9 and PA10), if devices areGD32F103xF/G/I/K, USART1 (PA2 and PA3) is also available for boot functions. It also can453.5. Power saving modesThe MCU supports three kinds of power saving modes to achieve even lower powerconsumption. They are sleep mode, deep-sleep mode, and standby mode.These operatingmodes reduce the power consumption and allow the application to achieve the best balancebetween the CPU operating time, speed and power consumption.⏹Sleep modeIn sleep mode, only clock of Cortex™-M3 is off. All peripherals continue to operate andany interrupt/event can wake up the system.⏹Deep-sleep modeIn deep-sleep mode, all clocks in the 1.2V domain are off, and all of IRC8M, HXTAL andPLLs are disabled. Only the contents of SRAM and registers are retained. Any interruptor wakeup event from EXTI lines can wake up the system from the deep-sleep modeincluding the 16 external lines, the RTC alarm, the LVD output, USB Wakeup and EthernetWakeup. When exiting the deep-sleep mode, the IRC8M is selected as the system clock.⏹Standby modeIn standby mode, the whole 1.2V domain is power off, the LDO is shut down, and all ofIRC8M, HXTAL and PLL are disabled.The contents of SRAM and registers (exceptBackup registers) are lost. There are four wakeup sources for the Standby mode,including the external reset from NRST pin, the RTC alarm, the FWDGT reset, and therising edge on WKUP pin.3.6. Analog to digital converter (ADC)⏹12-bit SAR ADC⏹Up to 1 MSPS for 12-bit resolution⏹Analog input signal voltage range: V SSA to V DDA (2.6 to 3.6 V)⏹Temperature sensorUp to three 12-bit multi-channel ADCs are integrated in the device. Each has a total of up to21 multiplexed external channels. An analog watchdog block can be used to detect thechannels, which are required to remain within a specific threshold window. A configurablechannel management block of analog inputs also can be used to perform conversions insingle, continuous, scan or discontinuous mode.The ADCs can be triggered from the events generated by the general level 0 timers (TIMERx)or the advanced timers (TIMER0 and TIMER7) with internal connection. The temperaturesensor generates a voltage that varies linearly with temperature. The analog supply voltageV DDA can vary from 2.6 V to 3.6 V. The output voltage of temperature sensor is internallyconnected to the ADC_IN16 input channel.3.7. Digital to analog converter (DAC)⏹Two 12-bit DACs with independent output channels⏹8-bit or 12-bit mode in conjunction with the DMA controllerThe two 12-bit buffered DACs are used to generate variable analog outputs. The DACchannels can be triggered by the timer or EXTI with DMA support.In dual DAC channeloperation, conversions could be done independently or simultaneously. The maximum outputvalue of the DAC is V REF+.3.8. DMA⏹7 channel DMA0 controller and 5 channel DMA1 controller⏹Peripherals supported: Timers, ADC, SPIs, I2Cs, USARTs, DAC, I2S and SDIOThe direct memory access (DMA) controllers provide a hardware method of transferring databetween peripherals and/or memory without intervention from the CPU, thereby freeing upbandwidth for other system functions. Three types of access method are supported:peripheral to memory, memory to peripheral, memory to memory.Each channel is connected to fixed hardware DMA requests. The priorities of DMA channelrequests are determined by software configuration and hardware channel number.Transfersize of source and destination are independent and configurable.3.9. General-purpose inputs/outputs (GPIOs)⏹Up to 112 fast GPIOs, all mappable on 16 external interrupt lines⏹Analog input/output configurable⏹Alternate function input/output configurableThere are up to 112 general purpose I/O pins (GPIO), named PA0 ~ PA15, PB0 ~ PB15, PC0~ PC15, PD0 ~ PD15, PE0 ~ PE15, PF0 ~ PF15 and PG0 ~ PG15 for the device to implementlogic input/output functions. Each GPIO port has related control and configuration registers tosatisfy the requirements of specific applications. The external interrupt on the GPIO pins ofthe device have related control and configuration registers in the Interrupt/event ControllerUnit (EXTI). The GPIO ports are pin-shared with other alternative functions (AFs) to obtainmaximum flexibility on the package pins. The GPIO pins can be used as alternative functionalpins by configuring the corresponding registers regardless of the AF input or output pins. Eachof the GPIO pins can be configured by software as output (push-pull or open-drain), input,peripheral alternate function or analog mode. Each GPIO pin can be configured as pull-up,pull-down or no pull-up/pull-down. All GPIOs are high-current capable except for analog mode.3.10. Timers and PWM generation⏹Up to two 16-bit advanced timer (TIMER0 & TIMER7), ten 16-bit general timers, and two16-bit basic timer (TIMER5 & TIMER6)⏹Up to 4 independent channels of PWM, output compare or input capture for each andexternal trigger input⏹16-bit, motor control PWM advanced timer with programmable dead-time generation foroutput match⏹Encoder interface controller with two inputs using quadrature decoder⏹24-bit SysTick timer down counter⏹ 2 watchdog timers (Free watchdog timer and window watchdog timer)The advanced timer (TIMER0 & TIMER7) can be seen as a three-phase PWM multiplexedon 6 channels. It has complementary PWM outputs with programmable dead-time generation.It can also be used as a complete general timer. The 6 independent channels can be usedfor。
