ST公司的STM32F102xx是高性能ARM Cortex™-M3 32位RISC内核的USB接入MCU,工作频率48MHz,具有高速嵌入式存储器(闪存64KB或128KB以及10KB或16KB SRAM),以及各种外设和连接两个APB总线的I/O.器件提供标准的通信接口(两个I2C,两个SPI,一个USB和三个USART)以及一个12位ADC和三个通用的16位计时器.主要用在应用控制和用户接口,医疗和手持设备,PC外设,游戏机和GPS平台,以及工业应用如PLC,逆变器,打印机和扫描仪,告警系统,视频互连和HVAC.本文介绍了STM32F102xx主要特性,应用,方框图以及STEVAL-MKI109V1/V2 eMotion演示板框图,电路图,材料清单和PCB元件布局图.
The STM32F102xx medium-density USB access line incorporates the high-performance ARM Cortex™-M3 32-bit RISC core operating at a 48 MHz frequency, high-speed embedded memories (Flash memory of 64 or 128 Kbytes and SRAM of 10 or 16 Kbytes), and an extensive range of enhanced peripherals and I/Os connected to two APB buses. All devices offer standard communication interfaces (two I2Cs, two SPIs, one USB and three USARTs), one 12-bit ADC and three general-purpose 16-bit timers.
The STM32F102xx family operates in the –40 to +85 °C temperature range, from a 2.0 to 3.6 V power supply. A comprehensive set of power-saving mode allows the design of low-power applications.
The STM32F102xx medium-density USB access line is delivered in the LQFP48 7 × 7 mm and LQFP64 10 × 10 mm packages.
The STM32F102xx medium-density USB access line microcontrollers are suitable for a wide range of applications.
