Technical Datasheet: 
STM32F405/415 Microcontrollers, STMicroelectronics
The STMicroelectronics ARM Cortex STM32 F405/415 ranges of microcontrollers are for embedded applications. The high performance STM32 F4 series 32-bit Flash MCU offers floating point unit (FPU) and digital signal processing (DSP) with industry standard core architecture.
ST’s 32-bit ARM® Cortex™ M4 core operates on the 168 MHz range with integrated peripherals including ADCs, DACs, timers and a crypto/hash processor (STM32F415 only) which provides hardware acceleration for AES 128, 192, 256, Triple DES, and hash (MD5, SHA-1). ST’s ART accelerator and the dynamic power scaling enable low current consumption in run mode.
