STMicro microcontroller families

• https://www.st.com/en/microcontrollers-microprocessors/stm32f4-series.html

Processors from two families to investigate:

• STM32F427/437 – serial audio interface, more performance and lower static power consumption
  
• STM32F410 – New milestone in outstanding power efficiency (89 µA/MHz and 6 µA in Stop mode), true random number generator, low-power timer, and DAC.
  
• STM32F413/F423 – Extends STM32F412 features with higher RAM and Flash memory density and an enhanced peripheral set including 10 UARTs, 3 CANs, SAI interface, a low-power timer, 2 DACs, 2 DFSDM with up to 6 filters. The STM32F423 includes AES encryption.
