Shenzhen Meiyuxin Technology Co., Ltd. [distributing IoT chips] sells STM32H730VBH6 ARM microcontroller - MCU High-performance & DSP DP-FPU, Arm Cortex-M7 MCU quality assurance! ! !

Product Description:

The STM32H730VBH6 device is based on a high-performance Arm® Cortex®-M7 32-bit RISC core running at up to 550 MHz. The Cortex® -M7 core has a floating-point unit (FPU) that supports Arm® double-precision (IEEE 754 compliant) and single-precision data processing instructions and data types. The Cortex-M7 core includes 32 KB instruction cache and 32 KB data cache. STM32H730xB devices support a full set of DSP instructions and a Memory Protection Unit (MPU) to enhance application security.

STM32H730VBH6 devices contain high-speed embedded memory Flash with 128 KB, up to 564 KB RAM (including 192 KB available in ITCM and AXI, plus 64 KB ITCM, plus 128 KB AXI, 128 KB DTCM, 48 KB AHB and 4 KB backup RAM), and a wide range of enhanced I/O and peripherals connected to the APB bus, AHB bus, 2x32-bit multi-AHB bus matrix and multilayer AXI interconnect supporting internal and external memory access. To increase application robustness, all memories have error code correction (one error correction, two error detection).

STM32H730VBH6 These devices embed peripherals that allow acceleration of math/arithmetic functions (CORDIC coprocessor for trigonometric functions and FMAC unit for filter functions). All devices provide three ADCs, two DACs, two operational amplifiers, two ultra-low-power comparators, a low-power RTC, four general-purpose 32-bit timers, twelve general-purpose 16-bit timers, including Two PWM timers for motor control, five low-power timers, a true random timer number generator (RNG), crypto acceleration unit and HASH processor. These devices support four digital filters for an external sigma-delta modulator (DFSDM). They also have standard and advanced communication interfaces.

• Standard peripherals

– Five I2C

– Five USARTs, five UARTs, and one LPUART

– Six SPIs, four I2S in half-duplex mode. For audio-grade precision, the I2S peripheral can be clocked by a dedicated internal audio PLL or an external clock to allow synchronization (note that the five USARTs also provide SPI slave capability).

– Two SAI serial audio interfaces

– One SPDIFRX interface with four inputs

– One SWPMI (Single Wire Protocol Master Interface)

– Management data input/output (MDIO) slave

– Two SDMMC interfaces

– USB OTG high-speed interface with full-speed capability (with ULPI)

– Two FDCAN plus one TT-FDCAN interface

– Ethernet interface

– Chrom-ART Accelerator

– HDMI-CEC advanced peripherals include

– Flexible Memory Control (FMC) interface

– Two Octo-SPI memory interfaces with On-The-Fly Decryption (OTFDEC)

– Camera interface for CMOS sensors

– LCD-TFT display controller

The STM32H730VBH6 devices operate from a 1.62 to 3.6 V supply in an ambient temperature range of –40 to +85 °C. The supply voltage can be reduced to 1.62 V by using an external power 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. A dedicated power input for USB provides more power options. A comprehensive set of power-saving modes allows the design of low-power applications.

The STM32H730VBH6 devices are available in various packages from 100 to 176 pins/ball. The set of included peripherals varies with the device selected. These features make the STM32H730xB microcontrollers 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
