![]() ![]() STM32 microcontroller in LQFP144 package.The only difference between those two is that NUCLEO-H755ZI-Q includes an including aĬryptographic Accelerator (Crypto/Hash processor).įeatures and board specifications copied from NUCLEO-H745ZI-Q or NUCLEO-H755ZI-Q development boards have STMicro STM32H745ZI and STM32H755ZI MCU respectively which both are dual-core variants which feature one ARM Cortex-M7 core running at 480MHz and one ARM Cortex-M4 core running at 240MHz, 1MB RAM, 2MB flash memory, as well as Ethernet PHY interface so that model covers most variations. There are many STM32 Nucleo-144 development boards and evaluation boards model variants available from STMicroelectronics today, however, for this STM32H7 (STM32 H7) series I read that it is suggested to first look at either NUCLEO-H745ZI-Q or NUCLEO-H755ZI-Q development board as the reference model of STM32 Nucleo-144 model with STM32H7 MCU (SoC). Most of the STM32 Nucleo-144 development boards with a powerful STM32H7 MCU only goes for around $27 to $29 US-dollars. Nucleo144) boards get the "144" their name from its header ("ST Zio connector") having 144-pins. All MCUs in the STM32H7 series also features an integrated JPEG codec accelerator (JPEG image decoder and encoder).Īll "Nucleo-144" (a.k.a. There are many variants though most are clocked at 480MHz or 550MHz for the Cortex-M7 MCU core, with some dual-core models also feature a 240MHz Cortex-M4 MCU core as well, plus practically all variants also include embedded flash storage on-chip as well as featuring Ethernet PHY interfaces for wired networking (meaning integrated 10/100Mbps Ethernet with RJ-45 port). STM32H7 is a low-cost 32-Bit MCU series based on single-core ARM Cortex-M7 or dual-core combining Cortex-M7 and Cortex-M4. STMicroelectronics now has relatively inexpensive development boards and evaluation board with very fast STM32 H7 series SoCs. Up to 0.5 Mbytes of on-chip Flash offers increased cycle life, up to 100,000 read/write cycles to ensure reliable storage of user data.Requesting HAL support for STMicroelectronics STM32 Nucleo-144 boards based on newer STMicro STM32H7 Cortex-M7 MCU.New ST ART Accelerator: working both on internal and external Flash (8 Kbytes of instruction cache).Ensures enhanced application responsiveness:.Targeting PSA and SESIP (Security Evaluation Standard for IoT Platforms) assurance level 3.Internal monitoring, which can erase secret data in the event of perturbation attacks, helps meet the PCI Security Standards Council (PCI SSC) requirements for Point Of Sales (POS) applications.
