STMicro unveils STM32MP2 Arm Cortex-A35/M33 MPU family starting with STM32MP25

STMicro has introduced its second generation of its STM32 MPUs (microprocessors) with the STM32MP2 moving to a 64-bit Arm architecture with Edge AI acceleration, multimedia features, graphics processing, and digital connectivity targeting industrial and IoT edge applications.

The new family follows the STM32MP1 Arm Cortex-A7/M4 series introduced in 2019, and the first member of the family is the STM32MP25 with up to two 1.5 GHz Cortex-A35 cores coupled with an Arm Cortex-M33 real-time core clocked at 400 MHz, a 3D GPU, and a 1.35 TOPS NPU for AI acceleration.

  • Networking
    • Up to 3x Gigabit Ethernet ports (with 2-port switch)
    • Time-Sensitive Networking (TSN)
  • Peripherals – PCIe Gen2, USB 3.0, 3x CAN-FD
  • Security
    • SESIP Level 3 certification
    • Arm TrustZone on Cortex-A and Cortex-M cores
    • Hardware encryption
    • Secure Provisioning Ecosystem
  • Temperature Range – -40 to +125°C
  • Package – Several to be announced including a 0.8mm-pitch chip-scale package (TFBGA)
  • 100% operating time for 10 years
  • 10-year longevity program

STM32MP25 development board software development tools

On the software side, developers will be able to leverage the existing STM32MPU ecosystem with the OpenSTLinux distribution that includes the X-Linux-AI framework (X-Linux-AI) and an STM32MPU distribution for Android that will benefit from the Vulkan API for 3D graphics acceleration., Software tools including the STM32Cube development tools and STM32Cube firmware will run bare metal or RTOS on the Cortex-M33 embedded core. The STM32MP25F-EV1 STM32MP25 evaluation board and an STM32MP25 discovery kit will be available in 2024.

STMicro is now sampling STM32MP25 devices to select OEM customers, and providing them with development boards, but volume production of chips and boards is only scheduled to begin in H1 2024, so this is an early announcement with limited public information and virtually no documentation. The new STM32MP2 MPU family was unveiled at the STM32 Summit event in Shenzhen, China on May 12-13. A few more details can be found in the press release and the product page.
