The highly integrated SH controller family is Freescale’s first low-pin-count S08 with 40 MHz internal clock source (ICS). It includes an additional ganged output that can use one bit to toggle multiple pins, which allows for higher current drive. The family also features strong analog capabilities, a complete set of serial modules, a temperature sensor and robust memory options ideal for general-purpose consumer and industrial applications in the 2.7V to 5.5V range.
