STM32MP1 Microprocessor Series

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.

Value Proposition

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.
