STM32F042 in STM32 Family
The STM32F042 sub-family from STMicroelectronics belongs to the STM32 mainstream Arm Cortex-M0 line, providing a cost-effective 32-bit MCU solution with integrated USB 2.0 crystal-less capability. Running at 48 MHz, these microcontrollers bridge the gap between 8-bit or 16-bit performance and more expensive 32-bit alternatives. They are specifically designed for applications requiring high-speed connectivity and standard peripherals in a compact footprint without the overhead of external timing components.
Variants in This Sub-Family
| Part Number | Difference | Stock |
|---|---|---|
| STM32F042C6T6 (STMicroelectronics) | 48-pin · LQFP | 912 |
Variants within the STM32F042 sub-family differ primarily by package size and memory density. Pin counts range from 20-pin TSSOP to 48-pin LQFP, influencing the number of available GPIOs and peripheral multiplexing options. Flash memory is offered at 16 KB or 32 KB, while all members maintain the 6 KB SRAM. Certain variants like the STM32F042F6 and G6 focus on extremely small footprints for compact integration.
