New Crusoe Pictures
Wondering what the underside of the Crusoe die looks like? Take a peak at the
underbelly of the TM5400, and TM3120 silicon dies shown below. These tiny little
processors have a bright future ahead of them... if they can handle it.
|The TM5400 is shown here measuring ~9.4mm X 8.4mm.
Slightly difficult to make out are the 474 balls (small black dots) which
enable its connections.|
|The TM3120 here, measures ~10.25mm X 8mm. Again
the small black dots are the balls used to enable its
Transmeta's Crusoe chips are packaged via Ball Grid Array (BGA) for
size considerations. The flexibility this packaging method allows processors to
be attached to the surface of the PCB with out soldering pins sticking out on
the other side. Standard PC processors like PPGA-370, do not need to consider
space limitations, whereas mobile processors must constrain to them.
Portability and decreased size go hand in hand for mobile processors.
| Compared to a
regular BGA chipset the TM5400 is close in size. Note the four holes
around the Crusoe processor (left).|
|Many people have speculated that the four holes are for a
heatsink attachment. With the Crusoe running at an average of 1 watt this
seems an unlikely necessity, at first. It appears they are intended
for the attachment of FormFactors' MicroSpring socket (and for a thermal
management device as well). FormFactor has recently inked a deal to provide
Transmeta with a socket for the Crusoe line of
This rig was used during the Crusoe Launch to illustrate how the
processor would be incorporated in final form, and what components would be
included with it. Titled "Crusoe Reference Designs". Notice again, the Crusoe
processor is about he same size as a standard BGA chipset.
In the final form, we can see two TM based laptops running typical windows 9X
applications. Not sure which processor is running in each laptop, but by the
laptop's size I would assume it is the TM5400.
|To put the size of the die into a more
understandable relationship, consider the potential computing power in the
TM5400, with that of a push pin.|
|The TM3120, which is designed especially is to work on
so-called Web Pads running mobile-linux is only slightly larger
then its sister processor.|
