The STM32F3x8 are mixed signal MCUs with ARM® Cortex®-M4 core (DSP, FPU) running at 72 MHz.
The devices are equipped with:
- Fast and Ultra fast comparators (<30 ns)
- Op-Amp with programmable gain (PGA)
- 12-bit DACs
- Ultra Fast 12-bit ADCs with 5 MSPS per channel (operating down to 1.8V)
- 16-bit sigma-delta ADCs, up to 21 single or 11 differential channels, and seven programmable gains per channel
- Fast 144 MHz motor control timers (resolution < 7 ns)
- CAN 2.0B communication interfaces
The STM32F3x8 devices operate at 1.8 V +/-8% to be supplied by an external voltage regulator
They are particularly suited for equipment operating at low voltage like consumer and gaming applications or sensor hubs, allowing further savings in system power consumption. The 1.8V operating voltage allows for direct interfacing with 1.8V application processors, while maximum dynamic on analog input can be reached with an optional analog supply.
Memory ranges from 32- to 256-Kbyte and packages from 32- to 100-pin.

As part of our embedded online event, we had the pleasure of filming with Reinhard Keil, a Senior Director of Embedded Tools at ARM.
This video is about the STM32L5, our recently announced ultra-low power microcontroller bringing a new security dimension. The STM32L5 is now in full production and all its ecosystem is available including hardware kits, software tools, firmware and all documentations of course. This is our first STM32 based on Cortex-M33 and its Trustzone and using specific ST security implementation - watch the video to find out more!
The STM32L5 is based on Arm® Cortex-M33 and TrustZone® technology combined with STMicroelectronics security implementation. On your STM32L562E-DK discovery board, TrustZone is disabled (factory setting) and you can develop as on any other STM32 device. This video shows how to enable TrustZone on STM32L562E-DK discovery using STM32CubeProgrammer and create, compile and debug or run a new project with STM32CubeIDE. It also shows how to open an example project delivered in STM32CubeL5 MCU Package, modify, compile and debug or run it. For further information, you can refer to AN5394 and AN5424 application notes.
