Description
STM32H750xB devices are based on the high-performance Arm® Cortex®-M7 32-bit RISC
core operating at up to 480 MHz. The Cortex® -M7 core features a floating point unit (FPU)
which supports Arm® double-precision (IEEE 754 compliant) and single-precision data
processing instructions and data types. STM32H750xB devices support a full set of DSP
instructions and a memory protection unit (MPU) to enhance application security.
STM32H750xB devices incorporate high-speed embedded memories with a Flash memory
of 128 Kbytes, up to 1 Mbyte of RAM (including 192 Kbytes of TCM RAM, up to 864 Kbytes
of user SRAM and 4 Kbytes of backup SRAM), as well as an extensive range of enhanced
I/Os and peripherals connected to APB buses, AHB buses, 2x32-bit multi-AHB bus matrix
and a multi layer AXI interconnect supporting internal and external memory access.
All the devices offer three ADCs, two DACs, two ultra-low power comparators, a low-power
RTC, a high-resolution timer, 12 general-purpose 16-bit timers, two PWM timers for motor
control, five low-power timers, a true random number generator (RNG), and a cryptographic
acceleration cell. The devices support four digital filters for external sigma-delta modulators
(DFSDM). They also feature standard and advanced communication interfaces.
Standard peripherals
– Four I2Cs
– Four USARTs, four UARTs and one LPUART
– Six SPIs, three I2Ss in Half-duplex mode. To achieve audio class accuracy, the
I2S peripherals can be clocked by a dedicated internal audio PLL or by an external
clock to allow synchronization.
– Four SAI serial audio interfaces
– One SPDIFRX interface
– One SWPMI (Single Wire Protocol Master Interface)
– Management Data Input/Output (MDIO) slaves
– Two SDMMC interfaces
– A USB OTG full-speed and a USB OTG high-speed interface with full-speed
capability (with the ULPI)
– One FDCAN plus one TT-FDCAN interface
– An Ethernet interface
– Chrom-ART Accelerator
– HDMI-CEC
Advanced peripherals including
– A flexible memory control (FMC) interface
– A Quad-SPI Flash memory interface
– A camera interface for CMOS sensors
– An LCD-TFT display controller
– A JPEG hardware compressor/decompressor
STM32H750xB devices operate in the –40 to +85 °C temperature range from a 1.62 to
3.6 V power supply. The supply voltage can drop down to 1.62 V by using an external power
supervisor (see Section 3.5.2: Power supply supervisor) and connecting the PDR_ON pin to
VSS. Otherwise the supply voltage must stay above 1.71 V with the embedded power
voltage detector enabled.
Dedicated supply inputs for USB (OTG_FS and OTG_HS) are available on all packages
except LQFP100 to allow a greater power supply choice.
A comprehensive set of power-saving modes allows the design of low-power applications.
STM32H750xB devices are offered in 3 packages ranging from 100 pins to 240 pins/balls.
The set of included peripherals changes with the device chosen.
These features make STM32H750xB microcontrollers suitable for a wide range of
applications:
Motor drive and application control
Medical equipment
Industrial applications: PLC, inverters, circuit breakers
Printers, and scanners
Alarm systems, video intercom, and HVAC
Home audio appliances
Mobile applications, Internet of Things
Wearable devices: smart watches
