48 MHz Cortex-M0+ with 64 KB Flash — what the memory budget means for the BOM
If your application needs over-the-air update staging, the 8 KB SRAM limits buffering — plan for page-wise Flash writes rather than full-image double-buffering.
The 105°C ceiling gives headroom above the typical 85°C industrial limit, useful when the PCB sits near a power supply or in a sealed enclosure.
There is no EOL notice or last-time-buy schedule, so it remains a safe selection for new production builds and long-life designs.
