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
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.
- 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

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).
* Input voltage range from 2.8 V to 5.5 V * 4 adjustable general purpose LDOs * 1 LDO for DDR3 termination (sink-source), bypass mode for low power DDR or as general purpose LDO * 1 LDO for USB PHY supply with automatic power source detection * 1 reference voltage LDO for DDR memory * 4 adjustable adaptive constant on-time (COT) buck SMPS converters * 5.2 V / 1.1 A boost SMPS with bypass mode for 5 V input or battery input * 1 power switch 500 mA USB OTG compliant * 1 power switch 500 mA/1000 mA general purpose * User programmable non-volatile memory (NVM), enabling scalability to support a wide range of applications * I²C and digital IO control interface * WFQFN 44L (5x6x0.8)
