8-bit Motor Control SF MCUs

S08SF

Roll over image to zoom in

The powerful 8-bit MC9S08SF4 MCU family is optimized to provide precise, quiet and safe control for simple motor control applications. An integrated, advanced set of features, including six timers and up to 18 general purpose input/output (GPIO) pins, provide highly accurate control and helps simplify overall system design. Enhanced protection circuit design and a wide operating temperature range (-40°C to +125°C) help systems run safely and reliably under variable conditions.
