Product type
STM32 microcontrollers are a family of 32-bit microcontrollers based on the ARM Cortex-M architecture. They are designed to provide a balance of performance, power efficiency, and ease of use, making them suitable for a wide range of embedded applications. These microcontrollers are typically made from silicon and incorporate various peripherals and interfaces to facilitate connectivity and control in electronic devices.
| Core architecture | ARM Cortex-M |
| Operating voltage | 1.8V to 3.6V |
| Flash memory size | Up to 2MB |
| RAM size | Up to 512KB |
| Clock frequency | Up to 400 MHz |
| GPIO pins | Up to 168 |
| Communication interfaces | I2C, SPI, UART, CAN, USB |
When selecting an STM32 microcontroller, consider the specific application requirements such as processing power, memory capacity, and peripheral support. It is important to specify the desired operating voltage, flash and RAM sizes, as well as communication interfaces needed for your project. Additionally, inquire about any necessary certifications or environmental ratings if the product will be used in specialized industries.
