5 ARM Cortex-M4F core. It is part of STMicroelectronics
7 ultra-low power series. The STM32L4x5 chip runs at up to 80 MHz and
8 integrates 128 KiB of SRAM and up to 1MiB of Flash. The B-L475E-IOT01A board
15 Currently B-L475E-IOT01A machines support the following devices:
17 - Cortex-M4F based STM32L4x5 SoC
18 - STM32L4x5 EXTI (Extended interrupts and events controller)
19 - STM32L4x5 SYSCFG (System configuration controller)
