Shenzhen Meiyuxin Technology Co., Ltd. [Distribution MCU] STM32H7A3ZIT6Q ARM Microcontroller - MCU Quality Assurance Brand new and original! ! !


Product Description:

STM32H7A3ZIT6Q devices are based on the high-performance Arm® Cortex®-M7 32-bit RISC core running at up to 280 MHz. The Cortex® -M7 core features an Arm® double precision floating point unit (FPU) (IEEE 754 compliant) and single precision data processing instructions and data types. STM32H7A3xI/G devices support a full set of DSP instructions and a Memory Protection Unit (MPU) to enhance application security.


STM32H7A3ZIT6Q devices contain high-speed embedded memory, dual-bank Flash up to 2 MB, about 1.4 MB of RAM (including 192 KB of TCM RAM, 1.18 MB of user SRAM and 4 KB of backup SRAM), and extensive enhanced I/O O and peripherals are connected to four APB buses, three AHB buses, a 32-bit multi-AHB bus matrix, and a multilayer AXI interconnect that supports internal and external memory access.


All devices provide two ADCs, two DACs (one dual and one single), two ultra-low-power comparators, a low-power RTC, twelve general-purpose 16-bit timers, two PWM timers, three low-power timers, and a true random number generator (RNG). The devices support nine digital filters (DFSDM) for the external sigma delta modulator. They also have standard and advanced communication interfaces.

• Standard peripherals

– Four I2C

– Five USARTs, five UARTs, and one LPUART

– Six SPIs, four I2S in full-duplex mode. For audio-grade accuracy, the I2S peripheral can be clocked by a dedicated internal audio PLL or an external clock for synchronization.

– Two SAI serial audio interfaces, one with PDM

– One SPDIFRX interface

– One Single Wire Protocol Master Interface (SWPMI)

– A 16-bit Parallel Synchronous Slave Interface (PSSI) shares the same interface as the digital camera)

– Management Data Input/Output (MDIO) slave

– Two SDMMC interfaces (one of which can be powered by a supply voltage separate from that of all other I/Os)

– Hi-Speed USB OTG with full speed capability (with ULPI)

– One FDCAN plus one TT-CAN interface

– Chrom-ART Accelerator

– HDMI-CEC

• Advanced peripherals include

– Flexible Memory Control (FMC) interface

– Two octo-SPI memory interfaces

– Digital camera interface for CMOS sensors (DCMI)

– Graphics Memory Management Unit (GFXMMU)

– LCD-TFT Display Controller (LTDC)

– JPEG hardware compressor/decompressor

The STM32H7A3ZIT6Q devices operate in an ambient temperature range of –40 to +85 °C with a 1.62 to 3.6 V supply. The supply voltage can be reduced to 1.62 V by 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 be kept above 1.71 V with the embedded supply voltage detector enabled. The USB OTG_HS/FS interface can be fed by the integrated USB regulator or via a separate supply.


A dedicated power input is available for one of the SDMMC interfaces for packages with more than 100 pins. It allows operation from a different voltage level than all other I/Os. A comprehensive set of power-saving modes allows the design of low-power applications. CPU and domain status can be directly monitored on some GPIOs configured as alternate functions.


The STM32H7A3ZIT6Q devices are available in various packages ranging from 64 pins to 225 pins/ball. The included peripherals for this group vary with the selected device. These features make the STM32H7A3xI/G 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
