MCU 32-Bit STM32F ARM Cortex M4 RISC 256KB Flash 3.3V 49-Pin WLCSP T/R

The STM32F411xC/xE devices are based on the high-performance ARM Cortex -M4 32-bit RISC core operating at a frequency of up to 100 MHz. Its Cortex -M4 core features a Floating point unit (FPU) single precision which supports 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) which enhances application security.The STM32F411xC/xE belongs to the STM32 Dynamic Efficiency product line (with products combining power efficiency, performance and integration) while adding a new innovative feature called Batch Acquisition Mode (BAM) allowing to save even more power consumption during data batching.The STM32F411xC/xE incorporate high-speed embedded memories (up to 512 Kbytes of Flash memory, 128 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB bus and a 32-bit multi-AHB bus matrix.All devices offer one 12-bit ADC, a low-power RTC, six general-purpose 16-bit timers including one PWM timer for motor control, two general-purpose 32-bit timers. They also feature standard and advanced communication interfaces.
