Shenzhen Meiyuxin Technology Co., Ltd. [recycling electronic inventory waste materials] STM32H742BGT6 ARM microcontroller - MCU High-performance & DSP DP-FPU, Arm Cortex-M7 MCU quality assurance Brand new original! ! !

Product Description:

The STM32H742BGT6 device is based on the high-performance Arm® Cortex®-M7 32-bit RISC core running at up to 480 MHz. The Cortex® -M7 core has a floating point unit (FPU) supporting Arm® double precision (IEEE 754 compliant) and single precision data processing instructions and data types. The STM32H742BGT6 devices support a full set of DSP instructions and a Memory Protection Unit (MPU) to enhance application security.

STM32H742BGT6 devices integrate high-speed embedded memory with up to 2 MB of dual-bank Flash and up to 1 MB of RAM (including 192 KB of TCM RAM, up to 864 KB of user SRAM and 4 KB of backup SRAM), as well as a wide range of enhanced Type I/O and connected peripherals to APB bus, AHB bus, 2x32-bit multi-AHB bus matrix and multi-layer AXI interconnect support internal and external memory access.

All STM32H742BGT6 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, and a true random number generator (RNG). The device supports four digital filters for an external sigma-delta modulator (DFSDM). They also have standard and advanced communication interfaces.

• Standard peripherals

– Four I2C

– Four USARTs, four UARTs and one LPUART

– Six SPIs, three I2S in half-duplex mode. For audio-grade precision, the I2S peripheral 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) slave

– Two SDMMC interfaces

– One USB OTG Full Speed and one USB OTG High Speed interface with Full Speed capability (with ULPI)

– One FDCAN plus one TT-FDCAN interface

– Ethernet interface

– Chrom-ART Accelerator

– HDMI-CEC

• Advanced peripherals include

– Flexible Memory Control (FMC) interface

– One Quad-SPI flash interface

– Camera interface for CMOS sensors

– One LCD-TFT display controller (only for STM32H743xI/G)

– JPEG hardware compressor/decompressor (only for STM32H743xI/G)

The STM32H742BGT6 devices operate from a 1.62 to 3.6 V supply at temperatures from –40 to +85 °C. The supply voltage can be reduced to 1.62 V using an external power supply monitor (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 to enable the embedded supply voltage detector. All packages provide USB dedicated power inputs (OTG_FS and OTG_HS) except LQFP100 which allows for larger power options. A comprehensive set of power-saving modes allows the design of low-power applications.

The STM32H742BGT6 devices are available in 8 packages ranging from 100 pins to 240 pins/balls. The set of included peripherals varies with the device selected. These features make the STM32H742BGT6 microcontroller suitable for 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
