Motorola DragonBall

Motorola/Freescale Semiconductor's DragonBall is Microprocessor design based on the famous 68000 core, but implemented as an all-in-one low-power solution for handheld computer use. It was designed by Motorola based in Hong Kong.

The DragonBall's only major design win was in earlier versions of the Palm Computing platform; from Palm OS 5 on it has been superceded by Arm-based XScale processors from Intel. The processor is also used in the AlphaSmart line of portable word processors. One such example is the Dana, and Dana Wireless.

The processor is capable of speeds of up to 16.67 MHz and can run up to 2.7 MIPS (million instructions per second), for the base and EZ model. It was extended to 37 MHz, 3.5 MIPS for the VZ model, and 66 MHz, 10.8 MIPS for Super VZ.

It is a 16-bit processor with 32-bit internal and external address bus (24-bit external address bus for EZ and VZ variants). It has many built-in functions, like a color and grayscale display controller, PC speaker sound, is able to directly access DRAM, Flash ROM, and mask ROM, and has built-in support for touch screens.

It is an all-in-one computer on a chip; before the dragonballEZ, Palm handhelds had twice as many ICs (integrated circuits).
