The 49 GPIOs, 12-channel 12-bit ADC, and internal oscillator reduce external component count.
The 80 MHz core with single-precision FPU handles motor-control FOC calculations, sensor fusion orientation math, or protocol parsing without a separate DSP or co-processor.
No official successor or second-source alternate is documented in the available records. For a BOM freeze, verify the date code window and consider securing a last-time-buy lot if production runs extend beyond the typical LTB notice period.
Package and integration
Housed in a 64-LQFP package with a 10x10 mm body, it fits standard four-layer PCB layouts. The 49 GPIOs are accessible on all four sides; route the USB DP/DM pair with controlled impedance and keep the CAN transceiver close to the MCU to minimize stub length.
