STM32F446RET6 Microcontroller: 180MHz,64-LQFP, Pinout and Features

The STM32F446RET6 is based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at a frequency of up to 180 MHz. The Cortex-M4 core features a floating-point unit (FPU) single precision supporting all Arm® single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) that enhances application security.

The STM32F446RET6 incorporates high-speed embedded memories (Flash memory up to 512 Kbytes, up to 128 Kbytes of SRAM), up to 4 Kbytes of backup SRAM, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, and a 32-bit multi-AHB bus matrix.

The STM32F446RET6 offers three 12-bit ADCs, two DACs, a low-power RTC, twelve general-purpose 16-bit timers including two PWM timers for motor control, two general-purpose 32-bit timers. It also features standard and advanced communication interfaces.

• Up to four I2Cs

• Four SPIs, three I2Ss full simplexes: to achieve audio class accuracy, the I2S peripherals can be clocked via a dedicated internal audio PLL or via an external clock to allow synchronization.

• Four USARTs plus two UARTs

• An USB OTG full-speed and a USB OTG high-speed with full-speed capability (with the ALPI), both with dedicated power rails allowing to use them throughout the whole power range.

• Two CANs

• Two SAIs serial audio interfaces: to achieve audio class accuracy, the SAIs can be clocked via a dedicated internal audio PLL.

• SDIO/MMC interface

• Camera interface

• HDMI-CEC

• SPDIF receiver (SPDIFRx)

• QuadSPI

Advanced peripherals include an SDIO, a flexible memory control (FMC) interface, a camera interface for CMOS sensors. Refer to Table 2 for the list of peripherals available on each part number.
