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.
