The STM32F446xC\/E devices are based on the high-performance Arm\u00ae<\/sup>\u00a0Cortex\u00ae<\/sup>-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\u00ae<\/sup>\u00a0single-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.<\/p>\n

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.<\/p>\n

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.<\/p>\n

They also feature standard and advanced communication interfaces.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
