+Introduction
|
|
+------------
|
|
+
|
|
+The STM32MP131/STM32MP133/STM32MP135 are Cortex-A MPU aimed at various applications.
|
|
+They feature:
|
|
+
|
|
+- One Cortex-A7 application core
|
|
+- Standard memories interface support
|
|
+- Standard connectivity, widely inherited from the STM32 MCU family
|
|
+- Comprehensive security support
|
|
+
|
|
+More details:
|
|
+
|
|
+- Cortex-A7 core running up to @900MHz
|
|
+- FMC controller to connect SDRAM, NOR and NAND memories
|
|
+- QSPI
|
|
+- SD/MMC/SDIO support
|
|
+- 2*Ethernet controller
|
|
+- CAN
|
|
+- ADC/DAC
|
|
+- USB EHCI/OHCI controllers
|
|
+- USB OTG
|
|
+- I2C, SPI, CAN busses support
|
|
+- Several general purpose timers
|
|
+- Serial Audio interface
|
|
+- LCD controller
|
|
+- DCMIPP
|
|
+- SPDIFRX
|
|
+- DFSDM
