    Has anybody got a photo of the inside of a CycloDS iEvolution Flash card I would be very interested to see what's inside

    Thank you for that, it looks like it has a CPU in it and I think it will be able to do a lot more than what they are admitting to, time will tell

    Away from you.
    How is there a CPU inside? You have no idea what you're talking about do you?

    Actel chip ? CPU.

    It's simple it has 24Mhz clock, not much use a high speed clock other than a CPU

    It the chip next to the micro SDHC socket I think it's a in house chip not off the shelf so will never know for sure but because of the high price it certainly could be

    It's not a CPU.

    And even if it was, how would you know it has a 24MHz clock?

    You can see the 24Mhz crystal in the first photo, have you got one to test? if you do you are one of the lucky ones, I really envy you if you do

    Whoops, thought you were talking about the massive black thing to the left of the mSD slot. My bad.

    Even so, a 24MHz CPU can't do shit.

    I think you are right I just had a look inside of an AceKard and it looks almost the same, if it hasn't got a CPU its overpriced to hell

    24mhz, the chip with that on it is an OSCILLATOR.

    what it does is, it creates a sinusodial wave with the frequency of 24.000mhz. This is important, to synchronize all chips on the PCB.

    It's kind of like a clock, where events are measured /timed / synchronized in oscillations.

    if one chip talks faster then the other one can read, the oscilator comes into play. Here, ever 10th swing or so, a bit of data can be send. Think about it as the governor (or the speed limit) of the highways on the PCB [​IMG]

    and there is no CPU on that PCB.
    the ACTEL chip is an field-programmable gate array (FPGA), which is more akin to integrated circuits then CPU's. It perfroms logic operations, and is conceptually different then a Central Processing Unit.

    The other large black chip (48 pins) is a most likely some flash memory chip. I can't read numbers on it, so i couldn't tell you. Yet, with 48 pins, i am certain that it's flash memory used for storing firmware / bootstrap.
    It appears that pin 3 on the chip is grounded. If i could read the number on the chip, i could tell you exactly what kind of memory it is, what mode it operates in, and what capacity it has.

    The MCU near the FPGA is a Silicon Labs T631 and the flash memory is a Samung K8D631UBM-YI07 (64M Bit (8M x8/4M x16) Dual Bank NOR Flash Memory). [​IMG]
    As stated on the iEvo metal box : FPGA + MCU and 8MB flash memory.
