其他系列 25MHz 64K@x8bit 4KB
Overview
The MC9S12E is a 112/80-pin, cost-effective, general-purpose MCU family, using the important on-chip features needed for your automotive designs.
The MC9S12E has full 16-bit data paths throughout.
The inclusion of a phase-lock look PLL circuit allows power consumption and performance to be adjusted to suit operational requirements.
An on-chip bandgap-based voltage regulator Vreg generates the internal digital supply voltage of 2.5 V VDD from a 3.15–5.5 V external supply range.
