ST公司的STM32F101x6, STM32F101xB和STM32F101x8是中等密度接入线的高性能ARM Cortex™-M3 32位RISC内核处理器,工作频率为32MHz,具有高速存储器(闪存高达128KB,SRAM高达16KB).它还有连接于两个APB总线的各种增强外设和I/O.所`有的器件有标准的通信接口(两个I2C,两个SPI和多达三个USART),一个12位ADC和三个别通用16位计时器.本文介绍了STM32F101xx的主要性能,方框图,时钟树和供电方案,以及Keil 公司的MCBSTM32评估板的性能和电路图.
The STM32F101x6, STM32F101xB and STM32F101x8 Medium-density access line family incorporates the high-performance ARM Cortex™-M3 32-bit RISC core operating at a 36 MHz frequency, high-speed embedded memories (Flash memory up to 128 Kbytes and SRAM up to 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, and up to three USARTs), one 12-bit ADC and three general-purpose 16-bit timers.
The STM32F101xx Medium-density Access line 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 STM32F101xx Medium-density access line family includes devices in four different
packages ranging from 36 pins to 100 pins. Depending on the device chosen, different sets of peripherals are included, the description below gives an overview of the complete range of peripherals proposed in this family.
These features make the STM32F101xx Medium-density Access line microcontroller family suitable for a wide range of applications:
●Application control and user interface
●Medical and handheld equipment
●PC peripherals, gaming and GPS platforms
●Industrial applications: PLC, inverters, printers, and scanners
●Alarm systems, Video intercom, and HVAC
STM32F101xx 主要特性:
■Core: ARM 32-bit Cortex™-M3 CPU
36 MHz maximum frequency,1.25 DMIPS/MHz (Dhrystone 2.1) performance at 0 wait state memory access
Single-cycle multiplication and hardware division
■Memories
32 to 128 Kbytes of Flash memory
6 to 16 Kbytes of SRAM |
