Introduction to STM32 Microcontroller

Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at Introduction to STM32 Microcontroller. This microcontroller is a new category of a microcontroller family it is a thirty-two-bit microcontroller also compatible with the ARM and Cortex M processor. Due to thirty-two bits compatibility, this module provides good performance, processing of digital signal and consumes less power and voltage. The modules used in most of the industries due to their compatibility with the cortex M0, M0+, M3, M4.

In today's post, we will have a look at its working, features, pinouts, applications and some other related parameters. So lets with the Introduction to STM32 Microcontroller.

Introduction to STM32 Microcontroller

• The STM32 is a type of microcontroller that offers the ARM Cortex-M thirty-two bits processor.
• This type of microcontroller is mostly used in different engineering projects.
•  This module has numerous series and parallel combinations for the connections so many other electronic devices can be linked with this module such as LCD display, a sensing module, electrical motors, etc.

• All modules of the STM32 are mounted with interior memory storage and random access memory (RAM).
• The price of some other STM family modules is higher. And STM series like STM32F0 and STM32F1 is consists of the twenty-four megahertz and sixteen pinouts.
• The STM32H7 modules use four hundred megahertz and have two forty pinouts at its casing.
• The sophisticated modules of STM series are used for FPU floating-point units applications where there is need of some special arrangements.

Pinout of STM32 Microcontroller

• Now we discuss the pinouts of STM32 with the detailed, that is described here with the detail.

Pin names	Pin Types:	Parameters
IOREF	It is power pinout.	At his pinout reference, 3,3 volts are applied.
RESET	It is power pinout.	This pinout is used to reset the controller.
+3.3 volts	It is power pinout.	At this pinout, 3.3 volts are applied as output that can also be used to give input to the microcontroller.
+5 volts	It is power pinout.	This pinout is only for five volts outputs.
GND	It is power pinout.	It is ground pinout.
A0-A1	Analog Pins and I2C	At this pinout, analogue voltage is found.
A4 and A5	Analog Pins and I2C	At this pinouts, I2C transmission of data is done A4 is SDA (Serial Data) pinout and A5 is SCL (Serial Clock) pinout.
D8-D15	Digital Pins and SPI	These are digital GPIO (General Purpose Input/Output) pins.
AVDD	Digital Pins and SPI	At this pinout, the analogue reference voltage is applied.
GND	Digital Pins and SPI	It is ground pinout.
D13, D12. D11 and D10	Digital Pins and SPI	These pinouts work as SCK (serial clock), MISO (master in slave out), MOSI (master out slave in) and CS pins respectively for SPI communication.
D0 to D7	Digital Pins and USART	These pinouts are Digital GPIO (General Purpose Input/Output) pins
D0 and D1	Digital Pins and USART	These pins act as Rx (receiver) and Tx (transmission) pins respectively for USART communication.
PC0, PC1, PC2, PC3, PC10, PC11, PC12, PC13, PC14, PC15	These are Port pinouts	All these are digital pinouts of port c of the module.
PD2	It is Port pinouts	It is the input and output pinout of Port D.
PA0, PA1, PA4, PA13, PA14, PA15	These are Port pinouts	All of these are input/output pinouts of Port A.
PB7, PB8 and PB9	These are Port pinouts	These are input/output pinouts of PORT B.
PH0 and PH1	These are Port pinouts	These are input/output pinouts of port H.
VBAT	It is power pinout.	This pinout used to provide power to the module form the battery.
+3.3 Volts	It is power pinout	This pinout provides 3.3 volts as output that can be used to power up the module.
+5V	It is power pinout	It is five volts output supply pinout.
VIN	It is power pinout	It is unregulated input power pinout.
RESET	It is power pinout	It used to Resets the microcontroller.
IOREF	It is power pinout	This is reference voltage pinout.
PC4, PC5, PC6, PC7, PC8, PC9	These are Port Pinouts	These are the input and output pinout of Port C.
PA2, PA3, PA4, PA6, PA7, PA10, PA11 and PA12	These are Port Pinouts	These are the Port A inputs and outputs pinouts.
PB1, PB2, PB3, PB4, PB5, PB6, PB8, PB9, PB10, PB12, PB14, PB15	These are Port Pinouts	These are the Port B inputs and output Pinouts.
U5V	It is power pinout	It is five volts power pinout.

It is a detailed tutorial on the STM32 I have explained each and everything related to this microcontroller. I tried my level best to describe this module in the simplest way, but still, if you have any question and query about this module please as in comments. Thanks for reading.  see you in the next tutorial. Have a nice day.
