ST公司的STM32F103CBT7是一款常用的增强型系列微控制器,适用于很多场合:一般情况下,可用于电机驱动和应用控制、医疗和手持设备、PC游戏外设和GPS平台;在工业上,可用在可编程控制器(PLC)、变频器、扫描仪和打印机上;同时,也可以用在警报系统、视频对讲、暖气通风空调系统等等电子产品。本文首先介绍芯片的简介、特性及应用领域,并给出高效数字光伏DC-DC电源设计方案的设计原理图、元器件列表及PCB元件布局图。

The STM32F103xx medium-density performance line family incorporates the highperformance ARM Cortex™-M3 32-bit RISC core operating at a 72 MHz frequency, highspeed embedded memories (Flash memory up to 128 Kbytes and SRAM up to 20 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses. All devices offer two 12-bit ADCs, three general purpose 16-bit timers plus one PWM timer, as well as standard and advanced communication interfaces: up to two I2Cs and SPIs, three USARTs, an USB and a CAN.

The devices operate from a 2.0 to 3.6 V power supply. They are available in both the –40 to +85 ℃ temperature range and the –40 to +105 ℃ extended temperature range. A comprehensive set of power-saving mode allows the design of low-power applications.

The STM32F103xx medium-density performance line family includes devices in six different package types: from 36 pins to 100 pins. Depending on the device ch..
