    Description

    STMicroelectronics STM32F446RCT6TR Microcontroller

     

    STMicroelectronics STM32F446RCT6TR Product Overview

    The STM32F446RCT6TR is a high-performance 32-bit ARM Cortex-M4 microcontroller from STMicroelectronics' STM32F4 series, featuring a floating-point unit (FPU) and DSP instructions for efficient signal processing. Housed in a 64-pin LQFP package, it is designed for industrial, motor control, and consumer applications requiring high computational power, advanced connectivity, and real-time responsiveness.

    Operating at up to 180 MHz, the Cortex-M4 core delivers 225 DMIPS performance. The device features 256 KB of flash memory, 128 KB of SRAM, and a flexible memory controller for external static memories. Integrated peripherals include three 12-bit ADCs (up to 2.4 Msps), two DACs, up to 18 timers, and a rich set of communication interfaces: four I²C, four SPI (with I²S), three USART, two UART, two CAN 2.0B, one USB 2.0 OTG (full-speed/high-speed), and one SDIO. Supply voltage is 1.7 V to 3.6 V. Operating temperature range is -40 °C to +85 °C. Mass is approximately 0.5 g.

    STMicroelectronics STM32F446RCT6TR Key Advantages

    The STM32F446RCT6TR employs the ARM Cortex-M4 core with FPU and DSP extensions, delivering 180 MHz performance and 225 DMIPS for computationally intensive tasks. The 256 KB flash and 128 KB SRAM provide ample memory for complex firmware with real-time OS and digital signal processing algorithms. The three 12-bit ADCs with 2.4 Msps conversion rate support high-speed data acquisition for motor current sensing and power monitoring, while the two DACs enable analog control signal generation. The extensive timer suite, including two 32-bit timers and two motor-control timers, makes this device ideal for precision PWM generation and position/speed feedback loops. The rich connectivity options — USB OTG (HS/FS), two CAN 2.0B, SDIO, and multiple USART/SPI/I²C interfaces — enable seamless communication with sensors, actuators, displays, and external storage. The FSMC allows expansion with external SRAM, SDRAM, or NOR/NAND flash for data-intensive applications. The 1.7 V to 3.6 V wide supply range supports battery-operated and low-voltage designs. The -40 °C to +85 °C temperature range ensures reliable operation in industrial environments.
