High-performance foundation line, Arm Cortex-M4 core with DSP and FPU, 512 Kbytes of Flash memory, 180 MHz CPU, ART Accelerator, Dual QSPI USB OTG HS/FS, seventeen TIMs, three ADCs and twenty communication interfaces The STM32F446xC/E devices are 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 STM32F446xC/E devices incorporate 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. All devices offer 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. https://elecena.pl/product/25746076/stm32f446ret6-cortex-m4-microcontroller-512-128kb-lqfp-64 2024-04-24 https://elecena.pl/product/25746076/stm32f446ret6-cortex-m4-microcontroller-512-128kb-lqfp-64 2024-07-13 https://elecena.pl/product/25746076/stm32f446ret6-cortex-m4-microcontroller-512-128kb-lqfp-64 2025-02-07 https://elecena.pl/product/25746076/stm32f446ret6-cortex-m4-microcontroller-512-128kb-lqfp-64 2025-10-10 https://elecena.pl/product/25746076/stm32f446ret6-cortex-m4-microcontroller-512-128kb-lqfp-64 2026-01-10
