STM32H725/735

The STM32H725/735 lines contain the Arm^® Cortex^®-M7 core (with double-precision floating point unit) running up to 550 MHz with optional extended ambient temperature range up to 125 °C (*).

Performance

• 550 MHz f_CPU/, 2778 CoreMark /1177 DMIPS executing from Flash memory, with 0-wait states thanks to its L1 cache
• L1 cache (32 Kbytes of I-cache +32 Kbytes of D-cache) boosting execution performance from external memories

Security

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 @V_DD = 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 V_BAT 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

Embedded peripherals

• Up to 35 communication interfaces including FD-CAN, USB 2.0 high-speed/full-speed, Ethernet MAC, camera interface
• Easily extendable memory range using the flexible memory controller with a 24-bit parallel interface, or the Dual Octo-SPI serial Flash memory interface
• Analog: 12-bit DACs, fast 16-bit and 12-bit ADCs
• Multiple 16- and 32-bit timers 
•  

The STM32H725/735 MCU line provides 512 Kbytes to 1 Mbyte Flash memory, 564 Kbytes of SRAM with the following architecture:

• 128 Kbytes of data TCM RAM for critical real time data
• 432 Kbytes of system RAM (up to 256 Kbytes can remap on instruction TCM RAM for critical real time instructions)
• 4 Kbytes of backup SRAM (available in the lowest-power modes)

The STM32H725/735 MCU lines are available in 100- to 176-pin packages in BGA and LQFP profiles, as well as a VFQFN68 and WLCSP115 packages.
