STM32F405VGT6V Description

The high-performance ARM? Cortex?-M4 32-bit RISC processor used in the STM32F405VGT6V series operates at a frequency of up to 168 MHz. A floating point unit (FPU) single precision is a feature of the Cortex-M4 core that supports all ARM single-precision data-processing instructions and data formats. Additionally, it incorporates a memory protection unit (MPU) that improves program security together with the whole range of DSP instructions.

High-speed embedded memories (Flash memory up to 1 Mbyte, up to 192 Kbytes of SRAM), up to 4 Kbytes of backup SRAM, and a wide range of enhanced I/Os and peripherals are all included in the STM32F405VGT6V family. These peripherals are connected to two APB buses, three AHB buses, and a 32-bit multi-AHB bus matrix.

All of the devices feature two general-purpose 32-bit timers, three 12-bit ADCs, two DACs, a low-power RTC, twelve general-purpose 16-bit timers, and two PWM timers for motor control. an authentic random number generator (RNG). They also have both conventional and cutting-edge communication interfaces.
