Product Summary

The MC9S12DT128BCFU is a 16-bit microcontroller unit. The MC9S12DT128BCFU has full 16-bit data paths throughout. However, the external bus can operate in an 8-bit narrow mode so single 8-bit wide memory can be interfaced for lower cost systems. The inclusion of a PLL circuit allows power consumption and performance to be adjusted to suit operational requirements.
