M340 Group
The M340 Group of microcontrollers are ideal for digital video camera, digital still camera and camera lens control
applications. They incorporate analog circuits required for optical image stabilization, autofocus and auto-exposure control.
The high-performance ARM CortexTM-M3 core provides high-speed computation functionality. Additionally, a high-resolution
programmable phase generator (PPG) enables smooth and quiet motor operation.
