📅 March 25, 2026⏱️ 8 min read🏷️ Tutorial
1. Determine Your Performance Requirements
The STM32 family is divided into several series based on performance:
- STM32F0 Series: Entry-level, ARM Cortex-M0, up to 48MHz
- STM32F1 Series: Classic series, Cortex-M3, up to 72MHz
- STM32F4 Series: High performance, Cortex-M4 with FPU, up to 180MHz
- STM32F7 Series: Very high performance, Cortex-M7, up to 216MHz
- STM32H7 Series: Ultimate performance, dual-core, up to 480MHz
- STM32L Series: Ultra-low power for battery applications
2. Memory Requirements
Flash memory ranges from 16KB to 2MB, RAM from 4KB to 1MB. Choose based on your code size and data needs.
3. Peripheral Requirements
Consider needed interfaces: USART, I2C, SPI, CAN, USB, Ethernet, ADC channels, timers, etc.
