ST公司的TM32F303x6/8系列是基于ARM®Cortex®-M4 RISC核的32位MCU,工作频率高达72MHz,嵌入了浮点单元(FPU),高速嵌入存储器包括高达64KB闪存,12KB SRAM以及各种增强I/O和连接两个APB总线的外设. 此外还集成了2个ADC,3个DAC,3个比较器和一个运放.主要用在BLDC/PMSM马达控制,无人机,遥控汽车和船舶等.本文介绍了TM32F303系统主要特性,功能框图和时钟树,以及评估板STEVAL-ESC001V1主要特性,系统架构图,电路图和电路图.
The STM32F303x6/8 family incorporates the high-performance ARM® Cortex®-M4 32-bit RISC core operating at up to 72 MHz frequency embedding a floating point unit (FPU), high-speed embedded memories (up to 64 Kbytes of Flash memory, 12 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses.
The STM32F303x6/8 microcontrollers offer up to two fast 12-bit ADCs (5 Msps), up to three ultra-fast comparators, an operational amplifier, three DAC channels, a low-power RTC, one general-purpose, 32-bit timer, one timer dedicated to motor control, and four general-purpose, 16-bit timers. They also feature standard and advanced communication interfaces: one I2C, one SPI, up to three USARTs and one CAN.
The STM32F303x6/8 family operates in the –40 to +85 ℃ and –40 to +105 ℃ temperature ranges from a 2.0 to 3.6 V power supply. A comprehensive set of power-saving m
