|HP Prime (DVT Prototype) Hardware Details |
Message #1 Posted by Adrien Bertrand on 9 Aug 2013, 9:53 a.m.
Here are some details about the HP Prime hardware, for those who are interested :)
Unlike the fx-CP400 which gave us a hard time (easy when you know the trick... ;) ), the HP Prime opens quite "easily" and reveals us its hardware:
We notice the references which were already at the back of our prototype: EA656MB for the motherboard and EA656KB for the keyboard and power board.
- Touch Color Display 3.5" diagonal with a resolution of 320x240px
- Processor (U101): Samsung S3C2416XH-40 - ARM9 clocked at 400 MHz maximum.
- RAM Memory (U200): Hynix H5MS2562NFR - 32 MB
- Flash Memory (U201): Samsung K9F2G08U0C-SCB0 - 256 MB
- Battery: Li-Ion 3.7V, 1500 mAh (5.55Wh)
In short, a fairly standard and simple architecture around three main distinct chips: RAM/ROM CPU.
Letís now look at the details ;)

In short, only documented and standard chips instead of proprietary ones or hidden in an ASIC, which is a nice change from the TI-Nspire or even more from the fx-CP400 :)
This calculator is positioning itself as a potential competitor to the TI-Nspire CX, as we wrote in our hands-on review (Omni topic) and the hardware confirms this idea, despite a slight weakness in the RAM amount.
In fact, some people already think of a Prime emulator on the Nspire and a Nspire one on the Prime, given the similar architecture! (But first, the machine will have to be open to native development ;) )
You can also compare the technical specs of the CX and the Prime with our comparator :

Oh and BTW, we have started a wiki about HP Calcs, the Prime was the starting event behind its creation, so it's more going to be oriented about it for a few days, but you are obviously welcome to contribute : http://tiplanet.org/hpwiki/index.php?title=HP_Prime
