It carries 128 KB of Flash, 32 KB of SRAM, and 2 KB of EEPROM — enough memory for moderate control loops and data logging without external storage.
80 MHz Cortex-M4F with FPU — what it buys the design
The 80 MHz core with single-precision FPU handles real-time sensor fusion, PID loops, and digital filtering without a separate DSP or coprocessor. The 22-channel 12-bit ADC can sample multiple analog inputs in sequence — useful for a multi-axis servo drive or a data-acquisition front end that would otherwise need an external multiplexer.
CAN 2.0 and USB OTG are on-chip, so this part can act as a CAN-to-USB gateway or a motor controller talking to a host over USB. The QEI block reads incremental encoder A/B signals directly — no external quadrature decoder needed.
The manufacturer lists this part as Active, though some distribution channels flag end-of-life indicators. For BOM freeze and long-term supply planning, confirm current availability at quote time.
