概要

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.

The set of included peripherals changes with the device chosen.
