High Performance Arm Cortex-M33 with TrustZone MCU, 250 MHz, 1 MB flash, 304 KB RAM, crypto, Ethernet, FDCAN, I3C, FMC, PLAY

概要

The STM32H553xx devices are high-performance microcontrollers of the STM32H5 series, based on the high-performance Arm^® Cortex^®-M33 32-bit RISC core. They operate at a frequency of up to 250 MHz.

The Cortex^®-M33 core features a single-precision floating-point unit (FPU), which supports all the Arm^® single-precision data-processing instructions and all the data types. This core implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) that enhances the application security.

The devices embed high-speed memories (1 Mbyte of dual bank flash memory and 304 Kbytes of SRAM), a flexible external memory controller (FMC) for devices with packages of 100 pins and more, one OCTOSPI memory interface (at least one Quad-SPI available on all packages), and an extensive range of enhanced I/Os and peripherals connected to three APB buses, three AHB buses, and a 32-bit multi-AHB bus matrix.

The devices offer security foundation compliant with the trusted-based security architecture (TBSA) requirements from Arm^®. They embed the necessary security features to implement a secure boot, secure data storage and secure firmware update. Besides these capabilities, the devices incorporate a secure firmware installation that allows the customer to secure the provisioning of the code during its production. A flexible life cycle is managed thanks to multiple levels of protection and secure debug authentication. Firmware hardware isolation is supported thanks to securable peripherals, memories, and I/Os, and to privilege configuration of peripherals and memories.

The devices feature several protection mechanisms for embedded flash memory and SRAM: readout protection, write protection, secure, and hide protection areas.

Dedicated peripherals reinforce security: a fast AES coprocessor, a secure AES coprocessor with DPA resistance and hardware unique key that can be shared by hardware with fast AES, a public key accelerator (PKA), DPA resistant an on-the-fly decryption engine for Octo-SPI external memories, an HASH hardware accelerator, and a true random number generator.

The devices offer active tamper detection and protection against transient and environmental perturbation attacks, thanks to several internal monitoring, generating secret data erase in case of attack. This helps to fit the PCI requirements for point of sales applications.

The devices offer three fast 12-bit ADCs, two DAC channels, an internal voltage reference buffer, two comparators, a low-power RTC, two 32-bit general-purpose timers, two 16-bit PWM timers dedicated to motor control, four 16-bit general-purpose timers, two 16-bit basic timers, and two 16-bit low-power timers.

The devices also feature standard and advanced communication interfaces, namely: three I²Cs, two I3Cs, four SPIs, four USARTs, four UARTs and one low-power UART, one SDMMC, two FDCANs, one USB full-speed, one USB Type-C^®/USB power delivery controller, one programmable logic array (PLAY).

The devices operate in the -40 to +85°C, -40 to +105°C, and, with exposed pad package, -40 to 125°C temperature ranges, with a 1.71 to 3.6 V power supply.

A comprehensive set of power-saving modes enables the design of low-power applications.

Independent power supplies are supported: an analog independent supply input for ADC, DACs, a 3.3 V dedicated supply input for USB, and a dedicated supply input for some GPIOs and SDMMC. A VBAT input is available to connect a backup battery, to preserve the RTC functionality, and to backup 32 32-bit registers and a 2-Kbyte SRAM.

The devices offer eight packages, from 48 to 144 pins.
