Product details

72 MHz Cortex-M3 with 64 KB Flash — the workhorse MCU for motor control and USB-connected designs

The 48-LQFP package (7x7 mm) is hand-solderable and widely supported by breakout boards and the STM32Cube ecosystem, so firmware bring-up is straightforward with SWD debug.

Memory sizing and peripheral fit for the BOM line

64 KB Flash and 20 KB SRAM handle moderate firmware images and data buffers — enough for a CANopen stack with a few hundred bytes of runtime variables, or a USB HID class with a 1 KB report descriptor. The 37 GPIOs are enough to drive a 16x2 character LCD plus a rotary encoder and a few sensors without an external port expander. CANbus and USB share the same bus, so a single part can bridge a CAN network to a USB host for data logging or firmware updates.

Frequently asked questions

What is the difference between STM32F103C8T6 and STM32F103C8T6TR?

The STM32F103C8T6 and STM32F103C8T6TR are the same silicon in the same 48-LQFP package. The TR suffix indicates Tape & Reel packaging for automated assembly; the base part number (without TR) typically ships in Tray or Tube. All electrical specifications — 72 MHz core, 64 KB Flash, 20 KB SRAM, 37 I/O — are identical.
