DragonBall
Motorola’s DragonBall series of integrated processors have been widely adopted for hand-held
PDA system designs. The power management of these processors is one of the key factors in the
success of hand-held products. The MC68328 and MC68EZ328 are the currently available
DragonBall processors, and both contain the same power control module. This application note
describes the function of the power control unit in detail.

DragonBall Common Reference Platform
Figure 1 shows a common MC68EZ328-based PDA design. It includes a pen-input touch panel,
an LCD panel, a communications port (RS232 or IrDA), memory, a speaker or buzzer, and a pager
receiver.
