SOM – STM32MP157C

SOM - STM32MP157C is the SOM based on STM32MP157C, STM32MP157C is a dual-core arm-cortex-a7 core processor operating at 650Mhz, the processor is also integrated with the Arm cortex-m4 coprocessor, Arm cortex-m4 integrates FPU and MPU. Cortex-a7 mainly does things at the operating system level, Cortex-m handles things at the MCU level. It can reach the optimal state at any time, making it suitable for various application scenarios.

Hardware

Here are the hardware details for Seeed SoM - STM32MP157C:

  • 1.STM32MP157C: Development board main control chip(Dual architecture processor: Arm® Cortex®-A7 and Cortex®-M4 )

  • 2.MT41K256M16TW-107:P: 512M16bitRAM Memory Chip

  • 3.STPMIC1APQR: Power Management Chip

  • 4.EMMC04G-M627: 4GeMMC Memory

  • 5.LED: When the power supply is successful, the PWR will go on. When the system is running normally, the USER will keep flashing.

  • 6.70-PIN connector: You can find the function for each pin from the table below:
