ARM® Cortex®-M4 core

The ARM® Cortex®-M4 processor is a high performance embedded processor with DSP instructions which allow efficient signal processing and complex algorithm execution. It brings an efficient, easy-to-use blend of control and signal processing capabilities to meet the digital signal control markets demand. The processor is highly configurable enabling a wide range of implementations from those requiring floating point operations, memory protection and powerful trace technology to cost sensitive devices requiring minimal area, while delivering outstanding computational performance and an advanced system response to interrupts.
32-bit ARM® Cortex®-M4 processor core
Up to 168 MHz operation frequency
Single-cycle multiplication and hardware divider
Floating Point Unit (FPU)
Integrated DSP instructions
Integrated Nested Vectored Interrupt Controller (NVIC)
24-bit SysTick timer

The Cortex®-M4 processor is based on the ARMv7-M architecture and supports both Thumb and Thumb-2 instruction sets. Some system peripherals listed below are also provided by Cortex®-M4:
Internal Bus Matrix connected with ICode bus, DCode bus, system bus, Private Peripheral Bus (PPB) and debug accesses (AHB-AP)
Nested Vectored Interrupt Controller (NVIC)
Flash Patch and Breakpoint (FPB)
Data Watchpoint and Trace (DWT)
Instrument Trace Macrocell (ITM)
Memory Protection Unit (MPU)
Serial Wire JTAG Debug Port (SWJ-DP)
Trace Port Interface Unit (TPIU)


On-chip memory

Up to 3072 Kbytes of Flash memory, including code Flash and data Flash
512B of OTP (one-time programmable) memory
192 KB of SRAM

The ARM® Cortex®-M4 processor is structured in Harvard architecture which can use separate buses to fetch instructions and load/store data. 3072 Kbytes of inner Flash at most, which includes code Flash and data Flash is available for storing programs and data, and

accessed (R/W) at CPU clock speed with zero wait states. Up to 192 Kbytes of inner SRAM is composed of SRAM0 (112KB) and SRAM1 (16KB) that can be accessed at same time, and including 64 KB of TCM (tightly-coupled memory) data RAM that can be accessed only by the data bus of the Cortex®-M4 core. The additional 4KB of backup SRAM (BKP SRAM) is implemented in the backup domain, which can keep its content even when the VDD power supply is down. The Figure of GD32F407xx memory map shows the memory map of the GD32F407xx series of devices, including Flash, SRAM, peripheral, and other pre-defined regions.

Clock, reset and supply management

Internal 16 MHz factory-trimmed RC and external 4 to 32 MHz crystal oscillator
Internal 48 MHz RC oscillator
Internal 32 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 voltage detector (LVD)
The Clock Control Unit (CCU) provides a range of oscillator and clock functions. These include 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 two AHB domains are 168 MHz. The maximum frequency of the two APB domains including APB1 is 42 MHz and APB2 is 84 MHz. See Figure 6 for details on the clock tree.
The Reset Control Unit (RCU) controls three kinds of reset: system reset resets the processor core and peripheral IP components. Power-on reset (POR) and power-down reset (PDR) are always active, and ensures proper operation starting from 2.4 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 warning 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.

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

The boot loader is located in the internal 30KB of information blocks for the boot ROM memory (system memory). It is used to reprogram the Flash memory by using USART0, USART2, and USB Device FS in device mode. It also can be used to transfer and update the Flash memory code, the data and the vector table sections. In default condition, boot from bank 0 of Flash memory is selected. It also supports to boot from bank 2 of Flash memory by setting a bit in option bytes.

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 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 (IRC16M, 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 23 external lines, the RTC alarm, the LVD output, and USB wakeup. When exiting the Deep-sleep mode, the IRC16M 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 IRC16M, 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, the FWDG reset, and the rising edge on WKUP pin.

Analog to digital converter (ADC)

12-bit SAR ADC's conversion rate is up to 2.6MSPS
12-bit, 10-bit, 8-bit or 6-bit configurable resolution
Hardware oversampling ratio adjustable from 2 to 256x improves resolution to 16-bit
Input voltage range: VSSA to VDDA (2.6 to 3.6 V)
Temperature sensor

Up to three 12-bit 2.6MSPS multi-channel ADCs are integrated in the device. It has a total of 19 multiplexed channels: 16 external channels, 1 channel for internal temperature sensor (VSENSE), 1 channel for internal reference voltage (VREFINT) and 1 channel for external battery power supply (VBAT). The input voltage range is between 2.6 V and 3.6 V. An on-chip hardware oversampling scheme improves performance while off-loading the related computational burden from the CPU. 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 can be used to perform conversions in single, continuous, scan or discontinuous mode to support more advanced use.
The ADC can be triggered from the events generated by the general-purpose level 0 timers (TMx) and the advanced-control timers (TM0 and TM7) 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 in a digital value.

Digital to analog converter (DAC)

Two 12-bit DAC converter of independent output channel
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 DACs are 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+.

3.8DMA

16 channels DMA controller and each channel are configurable (8 for DMA0 and 8 for DMA1)
Support independent 8, 16, 32-bit memory and peripheral transfer

uA级别智能门锁低功耗雷达模块让门锁更加智能省电节约功耗

发布时间： : 2022-02--18
uA级别智能门锁低功耗雷达模块让门锁更加智能省电节约功耗，指纹门锁并不是什么新鲜事，我相信每个人都很熟悉。随着近年来智能家居的逐步普及，指纹门锁也进入了成千上万的家庭。今天的功耗雷达模块指纹门锁不仅消除了繁琐的钥匙，而且还提供了各种智能功能，uA级别智能门锁低功耗雷达模块用在智能门锁上，可以实现门锁的智能感应屏幕，使电池寿命延长3-5倍，如与其他智能家居连接，成为智能场景的开关。所以今天的指纹门锁更被称为智能门锁。 今天，让我们来谈谈功耗雷达模块智能门锁的安全性。希望能让更多想知道智能门锁的朋友认识下。 指纹识别是智能门锁的核心 指纹识别技术在我们的智能手机上随处可见。从以前的实体指纹识别到屏幕下的指纹识别，可以说指纹识别技术已经相当成熟。指纹识别可以说是整个uA级低功耗雷达模块智能门锁的核心。 目前主要有三种常见的指纹识别方法，即光学指纹识别、半导体指纹识别和超声指纹识别。 光学指纹识别 让我们先谈谈光学指纹识别的原理实际上是光的反射。我们都知道指纹本身是不均匀的。当光照射到我们的指纹上时，它会反射，光接收器可以通过接收反射的光来绘制我们的指纹。就像激光雷达测绘一样。 光学指纹识别通常出现在打卡机上，手机上的屏幕指纹识别技术也使用光学指纹识别。今天的光学指纹识别已经达到了非常快的识别速度。 然而，光学指纹识别有一个缺点，即硬件上的活体识别无法实现，容易被指模破解。通常，活体识别是通过软件算法进行的。如果算法处理不当，很容易翻车。 此外，光学指纹识别也容易受到液体的影响，湿手解锁的成功率也会下降。 超声指纹识别 超声指纹识别也被称为射频指纹识别，其原理与光学类型相似，但超声波使用声波反射，实际上是声纳的缩小版本。因为使用声波，不要担心水折射会降低识别率，所以超声指纹识别可以湿手解锁。然而，超声指纹识别在防破解方面与光学类型一样，不能实现硬件，可以被指模破解，活体识别仍然依赖于算法。 半导体指纹识别 半导体指纹识别主要采用电容、电场（即我们所说的电感）、温度和压力原理来实现指纹图像的收集。当用户将手指放在前面时，皮肤形成电容阵列的极板，电容阵列的背面是绝缘极板。由于不同区域指纹的脊柱与谷物之间的距离也不同，因此每个单元的电容量随之变化，从而获得指纹图像。半导体指纹识别具有价格低、体积小、识别率高的优点，因此大多数uA级低功耗雷达模块智能门锁都采用了这种方案。半导体指纹识别的另一个功能是活体识别。传统的硅胶指模无法破解。 当然，这并不意味着半导体可以百分识别活体。所谓的半导体指纹识别活体检测不使用指纹活体体征。本质上，它取决于皮肤的材料特性，这意味着虽然传统的硅胶指模无法破解。 一般来说，无论哪种指纹识别，都有可能被破解，只是说破解的水平。然而，今天的指纹识别，无论是硬件生活识别还是算法生活识别，都相对成熟，很难破解。毕竟，都可以通过支付级别的认证，大大保证安全。 目前，市场上大多数智能门锁仍将保留钥匙孔。除了指纹解锁外，用户还可以用传统钥匙开门。留下钥匙孔的主要目的是在指纹识别故障或智能门锁耗尽时仍有开门的方法。但由于有钥匙孔，它表明它可以通过技术手段解锁。 目前市场上的锁等级可分为A、B、C三个等级，这三个等级主要是通过防暴开锁和防技术开锁的程度来区分的。A级锁要求技术解锁时间不少于1分钟，B级锁要求不少于5分钟。即使是高级别的C级锁也只要求技术解锁时间不少于10分钟。 也就是说，现在市场上大多数门锁，无论是什么级别，在专业的解锁大师面前都糊，只不过是时间长短。 安全是重要的，是否安全增加了人们对uA级别低功耗雷达模块智能门锁安全的担忧。事实上，现在到处都是摄像头，强大的人脸识别，以及移动支付的出现，使家庭现金减少，所有这些都使得入室盗窃的成本急剧上升，近年来各省市的入室盗窃几乎呈悬崖状下降。 换句话说，无论锁有多安全，无论锁有多难打开，都可能比在门口安装摄像头更具威慑力。 因此，担心uA级别低功耗雷达模块智能门锁是否不安全可能意义不大。毕竟，家里的防盗锁可能不安全。我们应该更加关注门锁能给我们带来多少便利。 我们要考虑的是智能门锁的兼容性和通用性。毕竟，智能门锁近年来才流行起来。大多数人在后期将普通机械门锁升级为智能门锁。因此，智能门锁能否与原门兼容是非常重要的。如果不兼容，发现无法安装是一件非常麻烦的事情。 uA级别低功耗雷达模块智能门锁主要是为了避免带钥匙的麻烦。因此，智能门锁的便利性尤为重要。便利性主要体现在指纹的识别率上。手指受伤导致指纹磨损或老年人指纹较浅。智能门锁能否识别是非常重要的。 当然，如果指纹真的失效，是否有其他解锁方案，如密码解锁或NFC解锁。还需要注意密码解锁是否有虚假密码等防窥镜措施。 当然，智能门锁的耐久性也是一个需要特别注意的地方。uA级别低功耗雷达模块智能门锁主要依靠内部电池供电，这就要求智能门锁的耐久性尽可能好，否则经常充电或更换电池会非常麻烦。 智能门锁低功耗雷达模块：让门锁更加智能省电节约功耗 在当今信息化时代，智能门锁已经成为人们生活中不可或缺的一部分。对于门锁制造商来说，如何提高门锁的安全性、实用性和便利性，成为他们面对的重要课题。随着人们对门锁智能化的需求越来越高，门锁的能耗问题也成为了门锁制造商需要重视的问题。为此，越来越多的门锁制造商开始推出以低功耗为主题的系列产品。在这样的背景下，智能门锁低功耗雷达模块应运而生。 智能门锁低功耗雷达模块是一种新型技术，其采取雷达技术对门锁周围的物体进行探测，一旦发现门锁附近有人靠近，便会将门锁自动解锁，无需使用钥匙。同时，在保持智能控制的前提下，实现了门锁省电、节约功耗，延长门锁使用寿命。 在使用智能门锁低功耗雷达模块的门锁中，控制电路和自动解锁机制是关键的部件。控制电路采用先进的芯片技术，通过优秀的功耗控制以实现模块化管理。而自动解锁机制不仅可以通过微波信号控制实现门锁的无钥匙解锁，还能够在门锁未处理的情况下自动锁定，保障门锁的安全。 智能门锁低功耗雷达模块的主要特点是：低功耗、高灵敏度和高可靠性。该模块在进行人体检测时，可以远距离探测到距离为5-7米远处的人体信号，目标检测速度极快，而且对门锁周围的环境要求不高。同时，该模块采用了自适应自动补偿技术，能够根据不同环境的变化自动调整信号发射和接收参数，减小误检率。 在使用智能门锁低功耗雷达模块的门锁中，其功耗可以做到非常低，一组电池能够支持门锁持续使用几年左右。而且这样的智能门锁除了具有自动解锁的功能，还可与APP相互匹配，实现了远程操作的便捷性。 总的来说，智能门锁低功耗雷达模块的问世，解决了门锁安全性和省电节省方面的问题，是智能门锁材料不可或缺的一部分。作为门锁制造商，只有不断创新，利用这种新型技术，将会在行业中占据重要的地位。 除了上文所述的主要特点和优势，智能门锁低功耗雷达模块还具有以下几点： 1. 实时监测门锁周围环境变化，通过物体的距离体积和运动来确定是否有人靠近门锁，并控制门锁的开启或关闭，使得门锁更加智能化。 2. 可对门锁附件进行检测，如门挂、门应急照明灯以及紧急呼叫按钮等，并及时给出响应，确保门锁能够正常运作。这样，门锁在不受干扰的情况下，能够 保持安全通道。 3. 通过智能学习技术，能够自适应网站多种环境的变化，让智能门锁低功耗雷达模块更加准确和精细的控制门锁的开关，节约能耗并延长使用寿命。 4. 能够与其他智能电器相连，如智能家居系统、电视等，形成智能家居生态圈，更好地控制家庭访客进出，让生活更加方便。 综上所述，智能门锁低功耗雷达模块的出现，对提升门锁能耗管理和智能化有着重要作用。门锁制造商只有将这些新型技术运用到门锁产品中，才能更加贴合用户需求，满足消费市场的日益增长的智能化需求。
