STM32F Introduction

STM32F is a 32-bit microcontroller, which is composed of an ARM Cortex-M3 core and features a high-speed USB 2.0 device. The STM32F provides the essential resources to support applications running in real time. STM32F also offers a large number of integrated peripherals, signal conditioning blocks, and external memory interfaces which allow adding value to your application.

The STM32F family is based on an advanced architecture with higher performance and integration levels than previous STM32 generations. It offers unmatched compactness, low power consumption, and high energy efficiency compared with any other similar devices in the market today.

The term “microcontroller” refers to an integrated circuit (IC) that combines both a CPU and RAM into one package. The CPU can be programmed to perform specific tasks, like controlling a motor or reading sensor data from an accelerometer. This makes it possible for a single chip to replace several discrete components, such as an MCU, memory chip, and other ASICs in an electronic device.

STMicroelectronics offers a number of development kits for their MCUs, including development boards with support for USB programming interfaces and external peripherals such as displays and buttons. These kits are ideal for prototyping applications before designing your own custom circuit board using these chipsets in your final product.

STM32F: Features, Usage, & Advantages

STM32F is a series of ultra-low-power microcontrollers based on the 32-bit ARM Cortex-M3 RISC core operating at a frequency of up to 100 MHz. It features a high level of integration, on-chip Flash memory instructions, an extensive range of enhanced peripherals, and an extensive range of application possibilities.

1. Features of STM32F:

• Uses ARM Cortex-M4F core

• It can be used for stand-alone applications or as a DSP extension to another microcontroller (for example, ARM Cortex-M3)

• On-chip debug interface with dedicated on-chip power supply

• Extensive range of on-chip peripherals: up to 4x UARTs, 3x I2Cs, 4x SPIs, 2x I2Ss/SPDIFs, 1x CAN controller, etc.

• Supports dynamic voltage scaling and low power modes down to 1.8V core voltage

• Up to 256 kB flash internal memory (STM32F0/1 series) or up to 512 kB flash internal memory (STM32F2 series).

2. Usage of STM32F:

In most cases, STM32F microcontrollers are used in embedded systems where low power consumption is necessary. Some examples include motor control systems, medical devices, industrial automation systems, and consumer electronics devices.

Also, they are often used in portable devices such as smartphones and tablets because they have low power consumption combined with decent performance capabilities.

3. Advantages of STM32F:

• Ultra-low power consumption: STM32F0 is optimized for ultra-low power consumption (1 μA/MHz) which allows developers to develop applications that can run for years on a single battery or coin cell.

• Ultra-fast execution: STM32F features an ARM® Cortex®-M0 core running at 24 MHz with a hardware floating point unit (FPU). It offers up to 15 times faster performance than standard 8051-based microcontrollers.

• High code density: High code density of up to 30% compared with standard 8051-based microcontrollers thanks to the Thumb®-2 instruction set and the compact architecture (18 Kbytes Flash memory).

• High integration: The STM32F includes a large number of peripherals on the chip such as timers, comparators, analog converters, and communication interfaces (SPI/USART/I²C/CAN) allowing customers to save time in designing their applications.

STM32F Discovery – How to Get Started?

The STM32F board is an ideal development platform for STM32 microcontrollers. It offers a wide range of features and peripherals that make it easy to get started with any STM32 microcontroller product. The board also supports a wide range of third-party expansion boards that can be used to extend the functionality of the device.

The board includes the new STM32 microcontroller with integrated Flash memory, SRAM, and EEPROM. The device features a high-performance RISC CPU with up to 256 Kbytes of Flash memory, 20 Kbytes of static RAM, and 8 Kbytes of EEPROM in an LQFP64 package.

The STM32F board has two I/O connectors with two rows each, and all the interfaces are broken out on these connectors. The first row features UART, SPI, and I2C interfaces, while the second row has USB OTG, CAN, SDIO and an external crystal oscillator connector.

The STM32F board comes with a preinstalled software development environment based on ARM’s Keil MDK-ARM toolset, which allows you to develop applications using C language or assembly language directly within the IDE environment or using Code Composer Studio (CCS) IDE software package.

STM32F – Audio Codec Demonstration

The STM32F Series microcontrollers (MCUs) are 32-bit Flash MCUs based on the ARM Cortex-M0+ core. They offer all the advantages of the STM32 family, including an extensive range of device choices, a high level of integration, and a large number of peripheral functions, with an optimized combination of features for real-time applications at an attractive price.

The STM32F is a low-cost and high-performance MCU with 64 Kbytes Flash memory, 20 Kbytes SRAM, and up to 40 MHz frequency. It is pin compatible with other F103 series devices such as the EASYIEE SPC5604PF1VLL6, but it has been designed specifically for audio applications thanks to its built-in DAC and three ADCs that allow to process of audio signals in full duplex mode. The device integrates a timer/counter (TC) which can be used as PWM output to drive up to 16 timers or 32 PWM channels.

In this example, we will demonstrate how to use the DAC peripheral by creating a simple audio codec demonstration board based on two STM32F MCUs running at 8 MHz internal clock frequency that can be configured as master or slave mode depending

Go Make Things With STM32F

Welcome to the STM32F family. It’s a great time to be an engineer, but it’s also a challenging time. The STM32F microcontroller family is the premier choice of engineers and developers who are making things happen.

The new series includes devices with a performance ranging from 30 DMIPS/240 CoreMark to over 3200 DMIPS/16500 CoreMark, the widest range of performance of any microcontroller family. The STM32 family includes the most memorable peripherals ever available on an ARM Cortex-M device.

In the past, they might have used other microcontrollers because those were the only tools available. Now, they choose STM32 because it provides the best combination of performance, features, and ease of use.

STM32F is an easy-to-use platform for embedded applications that need high performance, real-time capabilities, analog/digital conversion peripherals, connectivity, and security features.

The STM32F makes it easy to design products based on your needs: from smart energy management to wireless sensors; from industrial automation systems to consumer products; from mobile devices to automotive applications… you name it!

Using the STM32F to Setup a Serial Connection

The STM32F can be used to set up a serial connection. This is done by using the USART module. These MCUs integrate high-performance, real-time capabilities and peripheral sets that meet the requirements of applications that are both times critical and require a high level of integration. They also provide an extensive range of configurable analog peripherals that significantly expand their application field.

The STM32F has a built-in UART (serial port) and an RS232 level shifter, which makes it easy to set up RS232 communication. The STM32F also includes an onboard LED that can be used as a debugging tool.

To connect the STM32F103 to your PC via serial, follow these steps:

  • 1. Connect the TX pin of the UART to RDX on the PC using some serially-coupled wire. You can use any length of wire you want, as long as it isn’t too long. If you’re using a breadboard, make sure you ground the unused wires so they don’t interfere with other parts of your circuit.
  • 2. Connect the RX pin of your UART chip to TXD on your PC using a serially-coupled wire. Again, if you’re using a breadboard, make sure you ground unused wires so they don’t interfere with other parts of your circuit.
  • 3. Connect GND on your chip to GND on your PC (or vice versa). This is necessary for the proper operation of both devices but does not have any effect on signal integrity or speed.

Conclusion

STM32F is a series of ultra-low-power microcontrollers based on the 32-bit ARM Cortex®-M4 core. They integrate high-performance, analog, digital and serial interfaces, and peripherals to support application development in the areas of motor control, audio/video networking, industrial automation, and medical equipment.
