How to Choose Microcontrollers Components

1Match core architecture (ARM Cortex-M0/M3/M4/M7) to your processing needs and power budget.
2Verify peripheral availability (ADC, UART, SPI, I2C, USB) against your system requirements before committing to a specific MCU family.
3Consider Flash/RAM capacity with room for future firmware growth -- upgrading MCU mid-production is costly.
