HP Prime (DVT Prototype) Hardware Details



#7

Hi,

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.

They include:

  1. Touch Color Display 3.5" diagonal with a resolution of 320x240px
  2. Processor (U101): Samsung S3C2416XH-40 - ARM9 clocked at 400 MHz maximum.
  3. RAM Memory (U200): Hynix H5MS2562NFR - 32 MB
  4. Flash Memory (U201): Samsung K9F2G08U0C-SCB0 - 256 MB
  5. 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.

Let’s now look at the details ;)

Processor :

  1. Architecture : ARM (ARM9 ; 32 bit)
  2. Core : ARM926EJ-S
  3. Manufacturer : Samsung
  4. Reference : S3C2416
  5. Specs : 16KB I-cache; 16KB D-cache/MMU
  6. Frequency : 2 Modes : 266 MHz and 400 MHz
  7. Note : Features 2D Acceleration
  8. Official "Product Brief" (PDF)


RAM Memory :

  1. Type : DDR SDRAM
  2. Manufacturer : Hynix
  3. Reference : H5MS2562NFR E3M
  4. Capacity : 32 MB (256Mb (x16 device) = 4M x 4Bank x 16 I/O)
  5. Manufacturer Official Page
  6. Datasheet (Closest JFR model)


Flash Memory :

  1. Type : Flash NAND
  2. Manufacturer : Samsung
  3. Reference : K9F2G08U0C SCB0
  4. Capacity : 256 MB (2 Gb)
  5. Datasheet


Screen :

  1. Type : TFT
  2. Manufacturer : ?
  3. Reference : ?
  4. Dimensions : 3.5" (8,9 cm)
  5. Resolution : 320×240 px
  6. Pixel density : 114 ppi
  7. Color : Yes , 16-bit;
  8. Other : Capacitive multi-touch layer


Battery :

  1. Type : Rechargeable Battery
  2. Technology: Lithium-Ion
  3. Manufacturer : WiseWod Tehnology Co.
  4. Reference : 484461AR
  5. IEC 61960 Number : 1ICP6/51/63
  6. Dimensions : 4.8 * 43.8 * 61 mm
  7. Nominal voltage : 3.7 V
  8. Max. capacity : 1500 mAh
  9. Energy: 5.55 Wh
  10. Impedance : <= 60 mOhm


    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

    I see two pads that say BUZZ100 with [+] [-], I think we can connect a Buzzer -))

    and two pads that say UART_RX/TX (RS232?)

    Great for the buzzer and the UART.

    But before trying anything with UART, we'll need the ground... could anybody find it?

    Well, maybe BAT- or BUZZ- could work... idk :x

    #11

    It is almost a certainty that the negative side of the lithium polymer cell is the system ground.

    The serial rx and tx signals will most likely be CMOS logic levels, not TIA/EIA-232, so a level shifter will be required.

    #12

    Indeed, a buzzer could be there, but I'm not sure to see the point if it's not controllable anyway (even with Native code... ?)

    However, we'll see for RS232 ... :)

    Great for the buzzer !
    On HP calcs with a buzzer, there is a BEEP( command.
