STM32F103C8T6

The STM32F103C8T6 is one of the most widely adopted ARM Cortex-M3 microcontrollers in industrial and consumer electronics. Its combination of 72MHz performance, rich peripheral set (USB, CAN, I²C, SPI), and competitive pricing makes it a go-to choice for motor control, handheld instruments, GPS trackers, and industrial PLC designs.

Selection Tip: If your design requires more than 64KB flash, consider upgrading to the pin-compatible STM32F103CBT6 (128KB) or STM32F103RET6 (512KB, 64-pin LQFP). For cost-sensitive projects that don’t need USB or CAN, the STM32F100C8T6 (Value Line) offers a lower-cost alternative within the same pin footprint.

Supply Note (2026): STM32F103C8T6 is mature and widely stocked. Lead times through Prudix IC are typically 2-4 weeks. No EOL notice has been issued by STMicroelectronics.
