Shenzhen Meiyuxin Technology Co., Ltd. [distributing ST products] sells STM32F446RET6 ARM microcontroller - MCU High-performance foundation line, Arm Cortex-M4 quality assurance brand new original! ! !

Product Description:

The STM32F446RET6 device is based on a high-performance Arm® Cortex®-M4 32-bit RISC core running at up to 180 MHz. The Cortex-M4 core has floating-point unit (FPU) single-precision data processing instructions and data types that support all Arm® single-precision. It also implements a full set of DSP instructions as well as a memory protection unit (MPU) for enhanced application security.

STM32F446RET6 devices integrate high-speed embedded memory (flash up to 512 KB, up to 128 KB of SRAM), up to 4 KB of backup SRAM, and extensive enhanced I/O and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix. All devices provide three 12-bit ADCs, two DACs, a low-power RTC, twelve general-purpose 16-bit timers including two PWM timers for motor control, and two general-purpose 32-bit timers. They also have standard and advanced communication interfaces.

 Up to four I2C

 Four SPI, Three I2S Full Simplex: 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 USARTs plus two UARTs

 One Full-Speed USB OTG and one Full-Speed Capable USB OTG Hi-Speed (with ULPI), both with dedicated power rails allowing them to be used throughout the system power range

 Two CANs

 Two SAI serial audio interfaces: for audio-like precision, the SAI can be clocked by a dedicated internal audio PLL

 SDIO/MMC interface

 Camera interface

 HDMI-CEC

 SPDIF Receiver (SPDIFRx)

 Quad SPI

The STM32F446RET6 advanced peripherals include an SDIO, a Flexible Memory Control (FMC) interface, a camera interface for CMOS sensors.

The STM32F446RET6 devices operate from a 1.7 to 3.6 V supply over a temperature range of –40 to +105 °C. When using an external power supply, the supply voltage can be reduced to a 1.7 V supervisor (see Section 3.16.2: Internal reset shutdown). A comprehensive set of power-saving modes enables the design of low-power applications.

The STM32F446RET6 device is available in six packages with pin counts ranging from 64 to 144. The set of peripherals included varies with the device selected. These features make the STM32F446xC/E microcontrollers suitable for a wide range of applications, namely motor drives and controls, medical equipment, industrial (PLCs, inverters, circuit breakers), printers and scanners, alarm systems, video intercoms and HVAC, and Home audio equipment.
