STM32H735 MCUs include the following additional security features:
Crypto/hash hardware acceleration
Secure Firmware Install (SFI) embedded security services to authenticate and protect your software Ips while performing initial programming
Secure Boot Secure Firmware Update (SBSFU)
Power efficiency
Multi-power domain architecture enables different power domains to be set in low-power mode to optimize the power efficiency
Embedded SMPS to scale down the supply voltage. It can also be used to supply external circuitry and can also be combined with the LDO for specific use cases
USB regulator to supply the embedded physical layer (PHY)
147 μ/MHz typical @VDD = 3.3 V and 25 °C in Run mode (peripherals off)
3.5 μA typical in Standby mode (low-power mode)
1.45 *μA typical in VBAT mode without RTC, with 4 Kbytes backup (low-power mode)
Graphics
LCD-TFT controller interface with dual-layer support
Chrom-ART Accelerator™ enhances graphical content creation while saving core processing power, thus freeing up the MCU for other application needs
