STM32MP1 introduction

The STM32MP1’s flexible architecture is ideal for Linux and real-time applications.
Its mainlined:

  • OpenSTLinux Distribution 
  • STM32Cube ecosystem drastically reduce development time.
  • Purchase Discovery kits or Evaluation boards for STM32MP1 microprocessors. 
  • Download the free STM32CubeMP1 embedded software package containing the HAL, LL (low-layer) APIs, and middleware. Then install ST’s STM32CubeMX graphical software configuration tool (free) that supports pinout configuration, code generation and a power consumption calculator. Start with one of the many examples provided or build your own project.
  • STM32MP1 users can now choose from several IDEs from leading vendors and enjoy free license

The first group of STM32MP1 microprocessor series comes with dual Arm® Cortex®-A7 and Cortex®-M4 Cores

A general-purpose microprocessor portfolio enabling easy development for a broad range of applications, the STM32MP1 series is based on a heterogeneous single or dual Arm Cortex-A7 and Cortex-M4 cores architecture, strengthening its ability to support multiple and flexible applications, achieving the best performance and power figures at any time.
The Cortex-A7 core provides access to open-source operating systems (Linux/Android) while the Cortex-M4 core leverages the STM32 MCU ecosystem.


.

The STM32MP1 comes with many benefits including a rich development ecosystem:

  • Mainlined open-source Linux distribution with Android support available via partners   
  • STM32Cube firmware and embedded software libraries for Cortex-M4 core
  • An optional 3D graphics processing unit (GPU) provides for advanced HMI development   
  • Rich set of digital and analog peripherals
  • Advanced security features    
  • Optimized bill of materials (BOM) thanks to: High integration, packages compatible with low-cost PCB technologies (down to 4-layer plated-through hole (PTH) PCBs) and dedicated Power Management IC (PMIC)
  • Advanced tools from ST and Partners
  • Best-in-class local and online support
  • An extensive third-party ecosystem is available to help developers thanks to the ST Partner Program.
  • Rolling 10-year longevity commitment renewed every year

Flexible architecture

The single or dual Cortex-A7 cores are dedicated to open-source operating systems while the Cortex-M4 core is dedicated to real-time and low-power tasks.

  • Dual Cortex®A7 cores running at 650 MHz
    • 32-Kbyte L1 Instruction cache
    • 32-Kbyte L1 Data cache
    • 256-Kbyte Level 2 cache
  • Cortex®M4 core running at 209 MHz
    • a single-precision floating point unit (FPU)
    • a full set of digital signal processor (DSP) instructions
    • memory protection unit for enhanced application security

The Cortex-M4 core benefits from an embedded SRAM (448 Kbytes) to run purely deterministic code.
For instance, a customer currently using an STM32 MCU based on STM32Cube firmware, could transparently fully re-use his code on the Cortex-M4 core’s 448 Kbytes of SRAM, and add the Linux application (for instance an HMI) running on the Cortex-A7 core(s).

To meet a broad range of applications requirements, most peripherals can be allocated to either the Cortex-A7 or Cortex-M4 cores.

Power efficiency

  • Dynamic efficiency: the Cortex-A7 and Cortex-M4 cores can be run or stopped independently to achieve the best power efficiency for each processing and real-time application requirement.
  • Low-power modes: Multiple low-power modes are available including:
    • Standby mode: Down to 36 µW.
    • VBAT mode: Down to 4.5 µW. In this mode, it is possible to keep track of time using the real-time clock while keeping the system secure thanks to the tamper detect feature.

.

The STM32MP1 series is available in 3 different lines which are pin-to-pin compatible:

  • STM32MP157: Dual Cortex-A7 cores @ 650 MHz, Cortex-M4 core @ 209 MHz, 3D GPU, DSI display interface and CAN FD
  • STM32MP153: Dual Cortex-A7 cores @ 650 MHz, Cortex-M4 core @ 209 MHz and CAN FD
  • STM32MP151: Single Cortex-A7 core @ 650 MHz, Cortex-M4 core @ 209 MHz

Each line comes with a security option (cryptography & secure boot)

STPMIC1                                           

STPMIC1 – power supply for STM32MP1 and in general for MPU

The STPMIC1 is a fully integrated power management IC designed for products based on high integrated application processor designs requiring low power and high efficiency.
The device integrates advanced low power features controlled by a host processor via I²C and IO interface.

The STPMIC1 regulators are designed to supply power to the application processor as well as to the external system peripherals such as: DDR, Flash memories and other system devices.
The boost converter can power up to 3 USB ports (two 500 mA host USB and one 100 mA USB OTG).
Its advanced bypass architecture allows the smooth regulation of VBUS for USB ports from a battery as well as low-cost consumer 5 V AC-DC adapters.
4 buck SMPS are optimized to provide an excellent transient response and an output voltage precision for a wide range of operating conditions, high full range efficiency (η up to 90%) by implementing a low power mode with a smooth transition from PFM to PWM and also an advanced PWM synchronization technique with an integrated PLL for a better noise (EMI performance).
