Shenzhen Meiyuxin Technology Co., Ltd. [distributing microcontrollers] STM32H757BIT6 ARM microcontroller - MCU High-perf DSP DP-FPU Arm Cortex-M7 + Cortex-M4 2MBytes Quality assurance New original! ! !

Product Description:

The STM32H757BIT6 device is based on the high-performance Arm® Cortex®-M7 and Cortex®-M4 32-bit RISC cores. The Cortex®-M7 core runs at up to 480 MHz, while the Cortex®-M4 core runs at up to 240 MHz. Both cores feature a floating point unit (FPU) supporting Arm® single and double precision (Cortex®-M7 core) operations and conversions (IEEE754 compliant), including a full set of DSP instructions and a memory protection unit (MPU) to enhance applications security.

The STM32H757BIT6 devices contain high-speed embedded memory with dual banks of 2 MB of RAM, up to 1 Mbyte of RAM (including 192 KB of TCM RAM, up to 864 KB of user SRAM and 4 KB of backup SRAM), and a wide range of connections to Enhanced I/O and Peripheral Bus Matrix for APB bus, AHB bus, 2x32-bit multi-AHB and multilayer AXI interconnect access to support internal and external memory.

All STM32H757BIT6 devices provide three ADCs, two DACs, two ultra-low-power comparators, one low-power RTC, one high-resolution timer, twelve general-purpose 16-bit timers, two motor PWM timers control, five low-power timers, a true random number generator (RNG), and a cryptographic acceleration cell. These devices support four digital filters (DFSDM) for the external sigma-delta modulator. They also have standard and advanced communication interfaces

• Standard peripherals

– Four I2C

– DSI host interface.

The STM32H757BIT6 devices operate from a –40 to +85 °C temperature range with a 1.62 to 3.6 V supply. The supply voltage can be reduced to a 1.62 V monitor by using an external power supply (see Section 3.5.2: Power supply monitor) and connecting the PDR_ON pin to VSS. Otherwise the supply voltage must remain above 1.71 V, the embedded power supply enables the voltage detector.

All packages of the STM32H757BIT6 provide USB dedicated power inputs (OTG_FS and OTG_HS) to allow greater power selection. A comprehensive set of power-saving modes allows the design of low-power applications. The STM32H757BIT6 devices are available in 5 packages ranging from 156 pins to 240 pins/ball. The set of included peripherals varies with the device selected. These features make the STM32H757BIT6 microcontroller suitable for a wide range of applications:

• Motor drive and application control

• medical equipment

• Industrial applications: PLCs, inverters, circuit breakers

• Printers and scanners

• Alarm system, video intercom and HVAC

• Home audio equipment

• Mobile applications, Internet of Things

• Wearables: smart watches
