ME32F103 Series
The mainline Cortex-M3 workhorse — 72 MHz performance with rich peripherals.
Series Overview
The ME32F103 series delivers a full-featured ARM Cortex-M3 core at up to 72 MHz with 128 KB Flash and 16 KB RAM, packaged in familiar LQFP-48 (and larger) footprints. It is the right choice when your firmware outgrows value-class cores — more performance headroom, more peripherals, and room for communication stacks and richer applications.
