ST STM32F334x4 32位CortexR－M4 MCU开发方案

ST公司的STM32F334x4/6/8系列MCU是基于高性能ARM 32位CortexR-M4 RISC核,工作频率高达72MHz,并嵌入了浮点单元(FPU),同时集成了高达64KB闪存和12KB SRAM的嵌入存储器,以及连接到两条APB总线的各种增强I/O和外设.本文介绍了STM32F334x4/6/8主要特性,框图和时钟树, STM32F334 Discovery板主要特性,框图,电路图,PCB元件布局图和材料清单.

The STM32F334x4/6/8 family is based on the high-performance ARM 32-bit CortexR-M4 RISC core operating at a frequency of up to 72 MHz, and embedding a floating point unit (FPU). The STM32F334x4/6/8 family incorporates high-speed embedded memories (up to 64 Kbytes of Flash memory, up to 12 Kbytes of SRAM), and an extensive range of enhanced I/Os and peripherals connected to two APB buses.

The STM32F334x4/6/8 devices offer a High resolution timer,two fast 12-bit ADCs (5 Msps), up to three ultra-fast comparators, an operational amplifier, three DAC channels, a lowpower RTC, one high-resolution timer, 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.
