Product details

Entry-level Cortex-M0 with 48 MHz ceiling

The 128 KB Flash (128K x 8) is enough for a moderate application stack: a bare-metal control loop, a lightweight RTOS kernel, or a USB HID class driver. The 16 KB RAM (16K x 8) is the tighter constraint — it limits buffering for USB bulk transfers and leaves modest headroom for a small heap. If your design needs more than a few kilobytes of dynamic data, budget carefully or look at the STM32F0 family's larger-RAM variants.

Internal oscillator and POR simplify power-on sequence.
