The STM32F398VE is based on the high-performance ARM®Cortex®-M4 32-bit RISC core with FPU operating at a frequency of 72 MHz, and embedding a floating point unit (FPU), a memory protection unit (MPU) and an embedded trace macrocell (ETM). The family incorporates high-speed embedded memories (512 Kbyte of Flash memory, 80 Kbyte of SRAM), a flexible memory controller (FSMC) for static memories (SRAM, PSRAM, NOR and NAND), and an extensive range of enhanced I/Os and peripherals connected to an AHB and two APB buses.
The device offers four fast 12-bit ADCs (5 Msps), seven comparators, four operational amplifiers, two DAC channel, a low-power RTC, up to five general-purpose 16-bit timers, one general-purpose 32-bit timer, and three timers dedicated to motor control. They also feature standard and advanced communication interfaces: up to three I2Cs, up to four SPIs (two SPIs are with multiplexed full-duplex I2Ss), three USARTs, up to two UARTs and CAN. To achieve audio class accuracy, the I2S peripherals can be clocked via an external PLL.
The STM32F398VE operates in the -40 to +85°C and -40 to +105°C temperature ranges at 1.8 V ± 8% power supply. A comprehensive set of power-saving mode allows the design of low-power applications.
The STM32F398VE offers devices in LQFP100 package.

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.
