This MPU range is intended to provide compute and graphics support combined with power-efficient real-time control. The solution combines STM32MP1 technology with Nanya’s 4Gbit 16-bit DDR3L SDRAM and Toshiba’s 4GByte eMMC.
The STM32MP1 range has a heterogeneous architecture that combines up to two Arm Cortex-A7 and a Cortex-M4 core, providing fast processing and real-time tasks on a single chip, with high power efficiency. The STM32MP1 embeds a 3D GPU for HMI displays.
The STM32MP157C-EV1 evaluation board and two discovery kits (STM32MP157A-DK1 and STM32MP157C-DK2) are also available from Rutronik. The firmware package, STM32CubeMX facilitates software and hardware configuration of both the Cortex-A7 and Cortex-M4 cores. It handles C-code generation for the M4 core, DDR SDRAM interface configuration, and tuning tool. It can also generate Linux Device trees.
