STM32 Microcontroller
Introduction
Requirements based STM32 family is designed for high-performance, low-cost,
low-power embedded applications designed specifically for ARM Cortex-M3 core.
According to the performance into two different series: STM32F103 "Enhanced〞 series
and STM32F101 "Basic" series. Enhanced Series clock frequency of 72MHz, the highest
performance of similar products product; basic clock frequency of 36MHz, 16-bit
product prices get more than 16 products significantly enhance the performance and is
16 product users the best choice. Both series have built-in 32K to 128K of flash memory,
the difference is the maximum capacity of the SRAM and peripheral combinations. At
72MHz, executing from Flash, STM32 power consumption 36mA, are 32 products on
the market s lowest power, the equivalent of 0.5niA/MHz.
STM32F103 Performance Characteristics
1) Kernel. ARM32 bit CPU, the maximum operating frequency of 72MHz,
1.25DMIPS/MHz. Single-cycle multiply and hardware divide.
2) Memory. Integrated on-chip 32-512KB of Flash memory. 6-64KB SRAM memory.
3) Clock, reset, and power management. 2.0-3.6V power supply and I/O interface, the
drive voltage. POR, PDR and programmable voltage detector. 4-16MHz crystal.
Embedded factory tuned 8MHz RC oscillator circuit. 40 kHz internal RC oscillator
circuit. CPU clock for the PLL. With calibration for the RTC 32kHz crystal.
4) Low power consumption. Three kinds of low-power mode. Sleep, stop, standby
mode. For RTC and backup registers supply VBAT.
5) Debug mode. Serial debugging and JTAG interface.
6) Direct data storage. 12-channel direct data storage controller. Supported peripherals:
timers, ADC, DAC, SPI, IIC and USART.
7) Up to a maximum of 112 fast I / O ports. Depending on the modeL there are
26,37,51,80, and 112 I/O ports, all ports can be mapped to 16 external interrupt vectors.
In addition to the analog input, all of them can accept the input of 5V or less.
8) Up to a maximum of 11 timers. Four 16-bit timers, each with 4 IC / OC / PWM or
