48 MHz Cortex-M0 with USB and CAN on a single chip
It belongs to the STM32F0 series, targeting cost-sensitive industrial and consumer applications that still need a rich peripheral set — USB, CAN, multiple I²C and SPI buses, plus a 12-bit ADC and DAC.
64 KB Flash — what it buys the firmware team
64 KB of Flash is the mid-density option in the STM32F072 line. It holds a USB device stack plus a CANopen node with room for a modest application layer. If your firmware needs a full RTOS, graphics framebuffer, or over-the-air update staging area, you will want to step up to the 128 KB or 256 KB variants in the same family. The 16 KB RAM is enough for a couple of USB buffers and a small heap; watch the stack depth if you enable both CAN and USB simultaneously.
Industrial temperature and exposed-pad package
For production programs that need a second-source hedge, the pin-compatible STM32F072C8U6 (same silicon, commercial temperature range 0 to 70 °C) is a drop-in for indoor-only builds; for full industrial range, this U7 grade is the one to qualify.
