64 MHz Cortex-M0+ — what the speed buys you
The STM32G081EBY6TR: The 64 MHz clock on the Cortex-M0+ core handles a control loop with sensor fusion and a USB stack simultaneously. The 64 MHz rating is the core's maximum — the actual system clock may be lower depending on the flash wait-state setting and supply voltage (1.7 to 3.6 V).
The evidence carries a conflict: a lifecycle-stage marker of 'eol_hot' alongside a product status of 'Active'. This means the part is in a last-time-buy window or has been flagged for end-of-life by ST, though an official PCN date is not recorded here. A buyer should treat this as an NRND/EOL signal and verify the current LTB deadline with ST or an authorized channel.
