Stm32f401vet6 lqfp-100 ARM microcontroller - MCU agent, lowest spot price

describe

Stm32f401xd / Xe equipment is based on high-performance arm ® Cortex ®- M4 32-bit RISC core, operating frequency up to 84mhz. Its cortex ®- M4 core has floating point unit (FPU) single precision and supports all arm single precision data processing instructions and data types. It also implements a complete set of DSP instructions and a memory protection unit (MPU), which improves the security of the application.

Stm32f401xd / Xe contains high-speed embedded memory (512 kilobyte flash memory, 96 kilobyte SRAM), as well as extensive enhanced I / O and peripherals connected to two APB buses, two AHB buses and a 32-bit multi AHB bus matrix.

All devices are provided with a 12 bit ADC, a low-power RTC and six general-purpose 16 bit timers, including a PWM timer for motor control and two general-purpose 32-bit timers. They also have standard and advanced communication interfaces.
