The S12C is part of Freescale's 48/52/80 pin flash-based MCU family, giving you the power and flexibility of the 16-bit core for a wide range general-purpose industrial and automotive network applications. An on-chip bandgap-based voltage regulator (Vreg) generates the internal digital supply voltage (VDD) for a 2.97 V to 5.5 V external supply range. The inclusion of a phase-lock look (PLL) circuit allows power consumption and performance to be adjusted. A total of 50 I/O port pins and two input pins are available in the 80-pin package version. Up to 12 I/O port bits are available with wake-up capability from stop or wait mode.
