Cryptographic acceleration
The STM32F415xx and STM32F417xx devices embed a cryptographic accelerator. This
cryptographic accelerator provides a set of hardware acceleration for the advanced
cryptographic algorithms usually needed to provide confidentiality, authentication, data
integrity and non repudiation when exchanging messages with a peer.
●
●
The cryptographic accelerator supports DMA request generation.
Random number generator (RNG)
All STM32F415xx and STM32F417xx products embed an RNG that delivers 32-bit random
numbers generated by an integrated analog circuit.
General-purpose input/outputs (GPIOs)
Each of the GPIO pins can be configured by software as output (push-pull or open-drain,
with or without pull-up or pull-down), as input (floating, with or without pull-up or pull-down)
or as peripheral alternate function. Most of the GPIO pins are shared with digital or analog
alternate functions. All GPIOs are high-current-capable and have speed selection to better
manage internal noise, power consumption and electromagnetic emission.
The I/O configuration can be locked if needed by following a specific sequence in order to
avoid spurious writing to the I/Os registers.
Fast I/O handling allowing maximum I/O toggling up to 84 MHz.
Analog-to-digital converters (ADCs)
Three 12-bit analog-to-digital converters are embedded and each ADC shares up to 16
external channels, performing conversions in the single-shot or scan mode. In scan mode,
automatic conversion is performed on a selected group of analog inputs.
Additional logic functions embedded in the ADC interface allow:

It also provides a true random number generator that deliver 32-bit random numbers
produced by an integrated analog circuit.
