Thanks to EEWORLD's return event, the HPM6750EVK2 is a very powerful development board.
1. The packaging is a bit old. It should be that some boss was too busy and did not finish the trial. The box has been tossed around many times, which shows that the trial was done very carefully.
2. The packaging inside should also be original, with sponge protection, and the board is also very new:
3. Comes with two Type to USB data cables, one is male and the other is female.
4. Front of the development board:
4. Back:
The overall workmanship and materials are very good.
5. Since I couldn't find a suitable 5V plug, I used type to power it, and the RGB light on the board showed a breathing light effect.

[Development board introduction]
The HPM6700/6400 series MCU is a high-performance real-time RISC-V microcontroller from Shanghai Pioneer Semiconductor Technology Co., Ltd., which provides great computing power, efficient control capabilities and rich multimedia functions for industrial automation and edge computing applications.
performance
- The RISC-V core supports double-precision floating-point operations and powerful DSP extensions, with a main frequency of up to 816 MHz.
- 32KB of cache (I/D Cache) and up to 512KB of zero-wait instruction and data local memory (ILM/DLM), plus 1MB of built-in SRAM, greatly avoid the performance loss caused by low-speed external memory.
External storage
- 2 serial bus controllers, support NOR Flash / HyperFlash / PSRAM / HyperRAM, support NOR Flash online encryption execution, and provide highly scalable and compatible program space.
- SDRAM controller, supports 16/32-bit SDRAM/LPSDR at 166MHz.
- 2 SD/eMMC controllers can be used to connect WiFi modules and mass storage at the same time.
multimedia
- LCD display controller supporting up to 1366×768 60 fps display.
- Graphics accelerator, supports hardware acceleration such as graphics scaling, overlay, and rotation.
- JPEG hardware codec.
- Binocular camera improves AI image recognition capabilities.
- Four 8-channel full-duplex I2S and one digital audio output.
- Multi-channel voice and digital microphone interfaces facilitate high-performance speech recognition applications.
Rich peripherals
- Multiple communication interfaces: 2 Gigabit real-time Ethernet, support IEEE1588, 2 high-speed USB with built-in PHY, up to 4 CAN/CAN-FD and abundant UART, SPI, I2C and other peripherals.
- 4 groups of 32 PWMs with a precision of 2.5ns.
- 3 12-bit high-speed ADCs 5MSPS, 1 16-bit high-precision ADC 2MSPS, 4 analog comparators, up to 28 analog input channels.
- Up to 36 32-bit timers, 5 watchdogs and RTC.
Safety
- Integrated AES-128/256, SHA-1/256 acceleration engine and hardware key manager. Supports firmware software signature authentication, encrypted boot and encrypted execution to prevent illegal code replacement, tampering or copying.
- Security management based on the chip lifecycle and detection of multiple attacks further protects sensitive information.
- Built-in Boot ROM, can download and upgrade the firmware securely via USB or UART.
Power Systems
- It integrates a high-efficiency DCDC converter and LDO, supports single-power supply for the system, and can dynamically adjust the output voltage to achieve performance-power balance, taking into account the flexibility, ease of use and efficiency of the power supply.
- Multi-power domain design flexibly supports various low-power modes.
【Development method】
First, the most distinctive one is openharmony development, with warehouses:
The second is liteos, which is a lightweight operating system
The third is the RT-Thread operating system, RTT has been adapted to the development board.
Fourth, use Segger Embedded Studio for bare metal development.
In short, this is a very powerful development board, and I will work hard to learn how to use it well.
