Main differences between GD32MCU and STM32

?1. Kernel difference? 2. Main frequency difference? 3. Power supply difference? 4. Flash difference? 5. Power consumption difference? 6. USART difference? 7. ADC difference? 8. Resource difference

1. Kernel

GD32 uses the second-generation M3 core, and STM32 mainly uses the first-generation M3 core. There are many unrepairable bugs in the second-generation version of GD. The core used by GD is only 752419. ?

2. Main frequency

2.1 Using HSE: The main frequency of GD can run to 108M, while the main frequency of ST is only 72M

2.2 Using HIS: GD's main frequency can run to 108M, while ST's main frequency can't exceed 64M. For example: screen refresh, square root operation, motor control, etc. have high requirements for MCU speed, but when you want to reduce costs, GD is A very good choice. Using internal and external crystals, the way to configure the 108M clock can be downloaded by visiting 21ic or by visiting Weiyun to download related shared files: 21ic: http://bbs.21ic.com/icview-570529-1-1.html

3. Power supply

3.1 External power supply? The external power supply range of GD32 is 2.6~3.6V? The external power supply range of STM32 is 2~3.6VGD. The power supply range is relatively narrower than that of STM32.

3.2 Core voltage? GD32 core voltage is 1.2V? STM32 core voltage is 1.8V The core voltage of GD is lower than that of STM32, so the GD chip runs with lower power consumption when running. ?

4. Flash differences

4.1 Flash execution speed? The program execution in GD32 Flash is 0 wait cycles. ?Program execution speed in STM32 Flash. ST system frequency does not access flash wait time relationship: 0 wait period, when 0

4.2 Erasing time: Since GD's Flash is its own proprietary technology and ST's Flash is provided by a third party, there are some differences between GD's Flash and ST's Flash. The erasing time of GD is longer. For example: GD32F103/101 series Flash 128KB and below models, the typical value of Page Erase is 100ms, and the actual measurement is about 60ms. The typical value of Page Erase for corresponding ST products is 20~40ms, see product datasheet.

4.3 Flash encryption: ST's Flash has two layers of encryption mechanism, one is UID, and the other is read protection, but GD's Flash has a reorganization algorithm inside, physical addresses are continuous, but logical addresses are not. This can be used to prevent hard cracking. ?

5. Power consumption

STM32 power consumption table GD32 power consumption table It can be seen from the table below that under the same main frequency, the running power consumption of GD is smaller than that of STM32, but under the same settings, GD's shutdown mode, standby mode, sleep mode It is still higher than STM32. ?

6. USAR

There are two differences between TUSART GD and STM32:

1. When GD continuously sends data, there will be a Bit Idle between every two bytes.

2. The serial port of GD has only 1/2 stop bit modes when sending. STM32 has four stop bit modes of 0.5/1/1.5/2. These two differences of USART have basically no effect on communication, but the communication time will be longer. ?

7. ADC Differences

The input impedance of the GD and the setting of the sampling time are different from those of the ST. The input impedance of the GD sampling with the same configuration is relatively small.

8. FSMC

STM32 only has FSMC for large capacity (256K and above) above 100Pin. GD32 has FSMC for all 100Pin or above.

NS5300/NS5304 — HDMI RX interface chip, support HDMI to LVDS function, this is an independent application. It also supports the HDMI to parallel interface function. The HDMI 4K2K video signal can be sent to AVT Tx or AVT-4KTx or FPGA through the parallel interface, which is convenient for users who use FPGA for subsequent processing. At present, there is no other chip on the market that can convert the HDMI 4K2K serial signal to a parallel interface. This we are the only one in the world now.

NS5320 — HDMI transparent transmission chip, supports PS2 (keyboard and mouse interface), GPIO (general purpose signal transparent transmission), UART (serial port transparent transmission), IR (infrared remote control transparent transmission), I2C, ARC, CEC, DDC functions and transparent transmission Among them, ARC/CEC/DDC is the abbreviation of HDMI audio return/remote control two-way control/display data communication. They are all HDMI control and return functions except video and audio. That is to say, we support long-distance transmission of HDMI video, audio, and all HDMI control and return functions. Transmission can be via the AVT link or via a separate line. The NS5320 can be used alone or in conjunction with AVT.

NS5301/NS5305 — HDMI TX, used with NS5300/NS5304 — HDMI RX, can transmit 4K2K 60Hz video and audio over long distance through AVT or AVT-4K. NS5301/NS5305 and NS5300/NS5304 also integrate the same function of NS5320 transparent transmission chip, which means that our own HDMI interface chip integrates most of the functions of NS5320. If customers use our HDMI interface chip in the product, most In this case, it is no longer necessary to use the independent NS5320 HDMI control pass-through chip.

NS5311 is an independent BT656 to LVDS chip. This chip can directly light up the LCD screen using the LVDS interface from the BT656 interface output by AVT RX, AHD/TVI/CVI Rx. This chip supports two channels of LVDS, and a 1920X400 high-definition screen requires two channels of LVDS. The low-end screen of 1280x400 only needs one LVDS. That is to say, NS5311 can light up high-end 1920X400 high-definition screen using two-way LVDS.
