1.5 Pinouts and Packaging

MCF51EM256 Series Configurations

1.5.1 Pinout: 80-Pin LQFP

Pins not available on the 80-pin LQFP are automatically disabled for reduced current consumption. No

user interaction is needed. Software access to the functions on these pins will be ignored

Figure 2 shows the pinout of the 80-pin LQFP.
