Apple A4 Processor Revealed

January 27, 2010 Hardware, Site News — Miro

Word around the campfire is that Apple came out with a new device. Well, we just happened to be at the right place at the right time, and managed to sneek a peek at the new Apple A4 processor, which powers the new iPad.

From Apple’s official video we found the following markings: H8MBT00V0MTR-OEM; VTJK00782; 1SB009A 0940

The last four digits indicate the manufacture date. Apparently this particular chip came into existence in Week 40 of 2009, which happens to be end of September / early October. So it’s been around for awhile, that’s for sure.

The rest of the markings are harder to decode. We will be taking apart the iPad as soon as we can get our hands on it.

  2. Actually, that first string of characters is incorrectly typed.


    should read:


    BrightSideofNews is about to post an column detailing the architectural details of the A4 chip. Supposedly, it’s based on a dual-core, ARM design.

  6. It looks like a stacked package (like some TI OMAPs), with the logic (CPU+GPU+peripherals) on the bottom (the small green/gray slice just on top of the PCB) and a CSP DRAM chip on top (the bigger black slice with the markings on it).

    H8MBT00V0MTR does look like a Micron Mobile DDR part number.

    And btw, confirming the rumors, the A4 is just an ARM-based SoC.

  12. What is the source of this picture?

  13. From what i heard at the keynote, it runs at 1Ghz. The 3rd gen iPod Touch runs at 632Mhz, and after using a 3D application on mine for 5-10 minutes, it gets reasonably warm. That would lead most to think that a 1Ghz ARM chip would run pretty warm for just normal use.

  15. […] in mid January. In fact, these manufacture dates are after the week 40 manufacture time of the A4 processor in Apple’s photo of the iPad (granted, that photo was likely of a preproduction part).  HTC […]
