STM32F405 User Reference Manual Guide

●The STM32F405xx family of microcontrollers is based on the high-performance ARM Cortex-M4 32-bit RISC core operating at a frequency of up to 168 MHz They incorporate high-speed embedded memories (Flash memory up to 1 Mbyte, up to 192 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, three 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 a true random number generator (RNG). They also feature standard and advanced communication interfaces.
