Functional description 3.1. ARM® Cortex®-M3 core The 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.  32-bit ARM® Cortex®-M3 processor core  Up to 72 MHz operation frequency  Single-cycle multiplication and hardware divider  Integrated Nested Vectored Interrupt Controller (NVIC)  24-bit SysTick timer The Cortex®-M3 processor is based on the ARMv7 architecture and supports both Thumb and Thumb-2 instruction sets. Some system peripherals listed below are also provided by Cortex®-M3:  Internal Bus Matrix connected with ICode bus, DCode bus, system bus, Private Peripheral Bus (PPB) and debug accesses (AHB-AP) 3.2.  Nested Vectored Interrupt Controller (NVIC)  Flash Patch and Breakpoint (FPB)  Data Watchpoint and Trace (DWT)  Instrument Trace Macrocell (ITM)  Serial Wire JTAG Debug Port (SWJ-DP)  Trace Port Interface Unit (TPIU) On-chip memory  Up to 64 Kbytes of Flash memory  Up to 8 Kbytes of SRAM with hardware parity checking The ARM® Cortex®-M3 processor is structured in Harvard architecture which can use separate buses to fetch instructions and load/store data. 64 Kbytes of inner Flash and 8 Kbytes 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 2-2. GD32F150xx memory map shows the memory map of the GD32F150xx 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 32 MHz crystal oscillator  Internal 40 KHz RC calibrated oscillator and external 32.768 KHz crystal oscillator 33 GD32F150xx Datasheet  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 voltage detector (LVD) The Clock Control Unit (CCU) provides a range of oscillator and clock functions. These include speed internal RC oscillator and external crystal oscillator, high speed and low speed two types. Several prescalers allow the frequency configuration of the AHB and two APB domains. The maximum frequency of the AHB and two APB domains is 72 MHz. See Figure 2-6. GD32F150xx clock tree for details on the clock tree. GD32F1x0 Reset Control includes the control of three kinds of reset: power reset, system reset and backup domain reset. A system reset resets the processor core and peripheral IP components with the exception of the SW-DP controller and the Backup domain. Power-on reset (POR) and power-down reset (PDR) are always active, and ensures proper operation starting from 2.6 V and down to 1.8V. The device remains in reset mode when VDD is below a specified threshold. The embedded low voltage detector (LVD) monitors the power supply, compares it to the voltage threshold and generates an interrupt as a wake up message for leading the MCU into security. Power supply schemes:  VDD range: 2.6 to 3.6 V, external power supply for I/Os and the internal regulator. Provided externally through VDD pins.  VSSA, VDDA range: 2.6 to 3.6 V, external analog power supplies for ADC, reset blocks, RCs and PLL. VDDA and VSSA must be connected to VDD and VSS, respectively.  VBAT range: 1.8 to 3.6 V, power supply for RTC, external clock 32 KHz oscillator and backup registers (through power switch) when VDD is not present. 3.4. Boot modes At 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 SRAM In default condition, boot from main Flash memory is selected. The boot loader is located in the internal boot ROM memory (system memory). It is used to reprogram the Flash memory by using USART0 (PA9 and PA10) or USART1 (PA2 and PA3, PA14 and PA15). 3.5. Power saving modes The MCU supports three kinds of power saving modes to achieve even lower power consumption. They are sleep mode, deep-sleep mode, and standby mode. These operating modes reduce the power consumption and allow the application to achieve the best balance 34 GD32F150xx Datasheet between the CPU operating time, speed and power consumption.  Sleep mode In sleep mode, only the clock of CPU core is off. All peripherals continue to operate and any interrupt/event can wake up the system.  Deep-sleep mode In deep-sleep mode, all clocks in the 1.2V domain are off, and all of the high speed crystal oscillator (IRC8M, HXTAL) and PLL are disabled. Only the contents of SRAM and registers are retained. Any interrupt or wakeup event from EXTI lines can wake up the system from the deep-sleep mode including the 16 external lines, the RTC alarm, the LVD output, the CMP0&1 output, the USBD wakeup, the RTC tamper and Timestamp, the USART0 wakeup and the CEC wakeup. When exiting the deep-sleep mode, the IRC8M is selected as the system clock.  Standby mode In standby mode, the whole 1.2V domain is power off, the LDO is shut down, and all of IRC8M, HXTAL and PLL are disabled. The contents of SRAM and registers (except Backup 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 the rising edge on WKUP pin. 3.6. Analog to digital converter (ADC)  12-bit SAR ADC engine with up to 1 MSPS conversion rate  Conversion range: VSSA to VDDA (2.6 to 3.6 V)  Temperature sensor One 12-bit 1 μs multi-channel ADC is integrated in the device. It is a total of up to 16 multiplexed external channels and 3 internal channels for temperature sensor, voltage reference, VBAT voltage measurement. The conversion range is between 2.6 V < VDDA < 3.6 V. An analog watchdog block can be used to detect the channels, which are required to remain within a specific threshold window. A configurable channel management block of analog inputs also can be used to perform conversions in single, continuous, scan or discontinuous mode to support more advanced usages. The ADC can be triggered from the events generated by the general timers (TIMERx=1,2,14) and the advanced timer (TIMER0) with internal connection. The temperature sensor can be used to generate a voltage that varies linearly with temperature. It is internally connected to the ADC_IN16 input channel which is used to convert the sensor output voltage into a digital value. Each device is factory-calibrated to improve the accuracy and the calibration data are stored in the system memory area. 3.7. Digital to analog converter (DAC)  12-bit DAC converter of independent output channel 35 GD32F150xx Datasheet  8-bit or 12-bit mode in conjunction with the DMA controller The 12-bit buffered DAC channel is used to generate variable analog outputs. The DAC is designed with integrated resistor strings structure. The DAC channels can be triggered by the timer update outputs or EXTI with DMA support. The maximum output value of the DAC is VREF+. 3.8. DMA  7 channel DMA controller  Peripherals supported: Timers, ADC, SPIs, I2Cs, USARTs, DAC and I2S The flexible general-purpose DMA controllers provide a hardware method of transferring data between peripherals and/or memory without intervention from the CPU, thereby freeing up bandwidth 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 channel requests are determined by software configuration and hardware channel number. Transfer size of source and destination are independent and configurable. 3.9. General-purpose inputs/outputs (GPIOs)  Up to 55 fast GPIOs, all mappable on 16 external interrupt lines  Analog input/output configurable  Alternate function input/output configurable There are up to 55 general purpose I/O pins (GPIO) in GD32F150xx, named PA0 ~ PA15 and PB0 ~ PB15, PC0 ~ PC15, PD2, PF0, PF1, PF4-PF7 to implement logic input/output functions. Each of the GPIO ports has related control and configuration registers to satisfy the requirements of specific applications. The external interrupts on the GPIO pins of the device have related control and configuration registers in the Interrupt/event controller (EXTI). The GPIO ports are pin-shared with other alternative functions (AFs) to obtain maximum flexibility on the package pins. Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as input (with or without pull-up or pull-down) or as peripheral alternate function. Most of the GPIO pins are shared with digital or analog alternate functions. All GPIOs are high-current capable except for analog inputs. 3.10. Timers and PWM generation  One 16-bit advanced timer (TIMER0), one 32-bit general timer (TIMER1), five 16-bit general timers (TIMER2, TIMER13 ~ TIMER16), and one 16-bit basic timer (TIMER5)  Up to 4 independent channels of PWM, output compare or input capture for each general timer and external trigger input 36 GD32F150xx Datasheet  16-bit, motor control PWM advanced timer with programmable dead-time generation for output 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) can be used as a three-phase PWM multiplexed on 6 channels. It has complementary PWM outputs with programmable dead-time generation. It can also be used as a complete general timer. The 4 independent channels can be used for input capture, compare match output, generation of PWM waveform (edge-aligned and center-aligned Mode) and single pulse mode output. If configured as a general 16-bit timer, it has the same functions as the TIMERx timer. It can be synchronized with external signals or to interconnect with other general timers together which have the same architecture and features. The general timer can be used for a variety of purposes including general time, input signal pulse width measurement or output waveform generation such as a single pulse generation or PWM output, up to 4 independent channels for input capture/output compare. TIMER1 is based on a 32-bit auto-reload up/downcounter and a 16-bit prescaler. TIMER2 is based on a 16-bit auto-reload up/downcounter and a 16-bit prescaler. TIMER13 ~ TIMER16 is based on a 16-bit auto-reload upcounter and a 16-bit prescaler. The general timer also supports an encoder interface with two inputs using quadrature decoder. The basic timer, known as TIMER5, is mainly used for DAC trigger generation. They can also be used as a simple 16-bit time base. The GD32F150xx have two watchdog peripherals, free watchdog timer and window watchdog timer. They offer a combination of high safety level, flexibility of use and timing accuracy. The free watchdog timer includes a 12-bit down-counting counter and a 8-bit prescaler, It is clocked from an independent 40 KHz internal RC and as it operates independently of the main clock, it can operate in stop and standby modes. It can be used either as a watchdog to reset the device when a problem occurs, or as a free-running timer for application timeout management. The window watchdog timer is based on a 7-bit down counter that can be set as free-running. It can be used as a watchdog to reset the device when a problem occurs. It is clocked from the main clock. It has an early wake up interrupt capability and the counter can be frozen in debug mode. The SysTick timer is dedicated for OS, but could also be used as a standard down counter. The features are shown below:  A 24-bit down counter  Auto reload capability  Maskable system interrupt generation when the counter reaches 0  Programmable clock source 37 GD32F150xx Datasheet 3.11. Real time clock (RTC)  Independent binary-coded decimal (BCD) format timer/counter with five 32-bit backup registers  Calendar with subsecond, seconds, minutes, hours, week day, date, year and month automatically correction  Alarm function with wake up from deep-sleep and standby mode capability  On-the-fly correction for synchronization with master clock. Digital calibration with 1 ppm resolution for compensation of quartz crystal inaccuracy The real time clock is an independent timer which provides a set of continuously running counters in backup registers to provide a real calendar function, and provides an alarm interrupt or an expected interrupt. It is not reset by a system or power reset, or when the device wake up from standby mode. A 20-bit prescaler is used for the time base clock and is by default configured to generate a time base of 1 second from a clock at 32.768 KHz from external crystal oscillator. 3.12. Inter-integrated circuit (I2C)  Up to two I2Cs bus interfaces can support both master and slave mode with a frequency up to 400 KHz  Provide arbitration function, optional PEC (packet error checking) generation and checking  Supports 7-bit and 10-bit addressing mode and general call addressing mode The I2C interface is an internal circuit allowing communication with an external I2C interface which is an industry standard two line serial interface used for connection to external hardware. These two serial lines are known as a serial data line (SDA) and a serial clock line (SCL). The I2C module provides transfer rate of up to 100 KHz in standard mode and up to 400 KHz in fast mode. The I2C module also has an arbitration detect function to prevent the situation where more than one master attempts to transmit data to the I2C bus at the same time. A CRC-8 calculator is also provided in I2C interface to perform packet error checking for I2C data. 3.13. Serial peripheral interface (SPI)  Up to two SPIs interfaces with a frequency of up to 18 MHz  Support both master and slave mode  Hardware CRC calculation and transmit automatic CRC error checking The SPI interface uses 4 pins, among which are the serial data input and output lines (MISO & MOSI), the clock line (SCK) and the slave select line (NSS). Both SPIs can be served by the DMA controller. The SPI interface may be used for a variety of purposes, including 38 GD32F150xx Datasheet simplex synchronous transfers on two lines with a possible bidirectional data line or reliable communication using CRC checking. 3.14. Universal synchronous asynchronous receiver transmitter (USART)  Up to two USARTs with operating frequency up to 9 MHz  Supports both asynchronous and clocked synchronous serial communication modes  IrDA SIR encoder and decoder support  LIN break generation and detection  ISO 7816-3 compliant smart card interface The USART (USART0, USART1) are used to translate data between parallel and serial interfaces, provides a flexible full duplex data exchange using synchronous or asynchronous transfer. It is also commonly used for RS-232 standard communication. The USART includes a programmable baud rate generator which is capable of dividing the system clock to produce a dedicated clock for the USART transmitter and receiver. The USART also supports DMA function for high speed data communication. 3.15. Inter-IC sound (I2S)  One I2S bus Interfaces with sampling frequency from 8 KHz to 192 KHz, multiplexed with SPI0  Support either master or slave mode The Inter-IC sound (I2S) bus provides a standard communication interface for digital audio applications by 3-wire serial lines. GD32F150xx contain an I2S-bus interface that can be operated with 16/32 bit resolution in master mode or slave mode, pin multiplexed with SPI0. The audio sampling frequency from 8 KHz to 192 KHz is supported with less than 0.5% accuracy error. 3.16. HDMI CEC  Hardware support Consumer Electronics Control (CEC) protocol (HDMI standard rev1.4) The CEC protocol provides high-level control functions between the audiovisual products linked with HDMI cables. GD32F150xx contain a HDMI-CEC controller which has an Independent clock domain and can wake up the MCU from deep-sleep mode on data reception. 39 GD32F150xx Datasheet 3.17. Universal serial bus full-speed (USBD)  One full-speed USB Interface with frequency up to 12 Mbit/s  Internal main PLL for USB CLK compliantly The Universal Serial Bus (USB) is a 4-wire bus that supports communication between one or more devices. Full-speed peripheral is compliant with the USB 2.0 specification. The device controller enables 12 Mbit/s data exchange with a USB Host controller. Transaction formatting is performed by the hardware, including CRC generation and checking. The status of a completed USB transfer or error condition is indicated by status registers. An interrupt is also generated if enabled. The dedicated 48 MHz clock is generated from the internal main PLL (the clock source must use a HXTAL crystal oscillator) and the operating frequency divided from APB1 should be 12 MHz above. 3.18. Touch sensing interface (TSI)  Transfer sequence fully controlled by hardware  6 fully parallel groups implemented  18 IOs configurable for capacitive sensing Channel Pins and 6 for Sample Pins  Configurable transfer sequence frequency  Possible to implement the user specific transfer sequences  Sequence end and error flags / configurable interrupts  Spread spectrum function implemented Capacitive sensing technology can be used for the detection of a finger (or any conductive object) presence near an electrode. The capacitive variation of the electrode introduced by the finger can be measured by charging and detecting the voltage across the sampling capacitor. GD32F150xx contain a hardware touch sensing interface (TSI) and only requires few external components to operate. The sensing channels are distributed over 6 analog I/O groups including: Group0 (PA0 ~ PA3), Group1 (PA4 ~ PA7), Group2 (PC5, PB0 ~ PB2), Group3 (PA9 ~ PA12), Group4 (PB3, PB4, PB6, PB7) and Group5 (PB11 ~ PB14), 3.19.
