The 16-bit CPUXV2 core runs at 25 MHz, delivering a deterministic instruction cycle that suits real-time control loops and sensor fusion algorithms.
The 48-VFQFN package with exposed pad (7x7 mm) requires careful thermal pad stencil design and a via array under the paddle for heat dissipation in continuous operation.
Both share the same silicon and functional specs. The die and footprint are identical.
