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 0.5mA/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
