Motorola’s first ARM-based DragonBall was the DragonBall MX1, announced on June 12, 2001. It paired ARM’s ARM920T processor core with Motorola’s DragonBall approach to integrating handheld-system functions, and was specified to run at up to 200 MHz. A second chip announced alongside it, DragonBall Super VZ, kept a Motorola 68000-derived core and ran at 66 MHz.
What was Motorola’s first ARM-based DragonBall?
The DragonBall MX1 was the first product in Motorola’s DragonBall family to use an ARM processor core. Motorola announced it on June 12, 2001, identifying the core as ARM920T and specifying a maximum clock rate of 200 MHz. EE Times reported the launch details.
The announcement fulfilled a roadmap Motorola had presented in 2000: bring ARM-based products into the DragonBall line during 2001 while carrying forward familiar peripheral sets and interface structures. The aim was to change the processor architecture without abandoning the family’s focus on integrated handheld systems. Contemporary roadmap coverage described that strategy.
How the MX1 differed from the Super VZ
Motorola announced the MX1 and Super VZ together, but they served different performance tiers and did not share the same CPU architecture. EE Times reported the launch clock rates and product positioning as follows.

| Chip | CPU architecture | Reported clock rate | Positioning |
|---|---|---|---|
| DragonBall MX1 | ARM920T | Up to 200 MHz | Higher-end handhelds and wireless products |
| DragonBall Super VZ | Motorola 68000-derived core | 66 MHz | Lower-end handheld applications |
The figures are the maximum or operating clock rates reported for the chips at the June 2001 launch, not a direct benchmark comparison. Clock speed alone does not establish how quickly different architectures or complete devices perform.
Why Motorola moved DragonBall from 68K to ARM
Earlier DragonBall processors descended from Motorola’s 68K family. The original MC68328 was a low-power, 68EC000-based integrated processor for portable organizers, combining processing with functions such as LCD control and PCMCIA support. Motorola later said the M68328, code-named DragonBall, had been introduced in May 1995 and was used in U.S. Robotics’ Pilot organizer. Motorola’s MC68328 reference manual and NXP’s archived product brief document the earlier chip’s lineage and capabilities; Motorola’s 1996 announcement gives the product history.

By 2001, the handheld market was changing. ARM offered Motorola a route to higher clock rates and a growing embedded and mobile software ecosystem, while the DragonBall name and integrated peripheral approach remained useful to device makers. Contemporary reporting also placed the move in the context of competition from Intel’s ARM-based XScale in the Palm market; Motorola had shipped more than 11 million DragonBall-family units by that time. EE Times covered the competitive pressure and shipment figure.
Motorola executive Eric Svensson summarized the architectural shift at the launch: “What’s really new is that we’re introducing the ARM core into the DragonBall family.” The statement was reported by EE Times.

What devices and software the MX1 was intended to support
The MX1 was aimed at higher-end handhelds and wireless devices, including Palm OS handheld computers, 2.5G and 3G mobile products, smartphones, information appliances, and web browsers or tablets. Its system-on-chip integration—including Bluetooth-capable functionality—was intended to reduce power use, board space, and overall system cost. Those were design goals and target markets, not guarantees that every device using the chip would include Bluetooth or achieve a particular saving. EE Times’ launch report describes the MX1’s positioning and capabilities.
The broader DragonBall family was associated with Palm OS, Windows CE/Pocket PC, Linux, and Symbian EPOC. In a later announcement dated September 18, 2002, Microsoft said Motorola’s ARM-based DragonBall platform application-development system supported Windows CE 3.0, with Windows CE .NET support expected by the end of that year. That announcement documents platform-development support; it does not establish that every MX1 device shipped with either Windows CE version. Microsoft’s announcement provides the dated qualification.

How the MX1 compares with the original DragonBall
The MX1 was more than a faster clocked version of the original MC68328: it marked a change from a 68K-derived processor to ARM. The older chip was designed for low-power portable organizers and combined a 16 MHz-class processor with LCD, PCMCIA, serial, and other portable-system functions. The MX1 moved the family toward higher-end connected handhelds, with an ARM920T core specified up to 200 MHz and wireless-oriented integration. The comparison describes distinct product generations; clock figures do not by themselves quantify real-world device performance.
