    Some details about the iPhone hardware are now trickling out.

    Via MacWorld (http://www.macworld.co.uk/news/index.cfm?RSS&NewsID=18437):

    The CPU used incorporates an ARM1176JZF CPU running at 620MHz:

    Power consumption: 0.280W at full speed, with aggressive power saving features via "Intelligent Energy Manager" that can save 25% - 50% of the power. i.e., it is possible that in certain modes of operation the CPU is only using 0.140W.

    I bet that the extended iPhone battery life since the initial reports was partially due to implementation of IEM.

    It's a shame that there is no Java support on the iPhone, given that the CPU supports Java, and that so many mobile applications are written in it.

    It appears that the CPU is fabbed by Samsung as part of a SOC (System On Chip) that incorporates hardware to aid with media playback (H.264, etc) and probably a decent mobile graphics core for the interface effects (although the ARM CPU also has vector floating point that is meant to aid in this task). 128MB of RAM is also included within the package.

    Please post your other iPhone hardware information here.

    Nice diagrams showing the part numbers of all the parts, for easy hardware identification.

    Here's a couple ...

    Infineon PMB8876

    S-GOLD2, part of Infineon’s S-GOLD baseband family, combines EDGE modem technology with the multimedia functions for mobile phone applications.

    S-GOLD2, part of Infineon’s S-GOLD baseband family, combines EDGE modem technology with the multimedia functions for mobile phone applications. The S-GOLD2 implements an ARM926 CPU and supports high-resolution display interface, dedicated camera interface, hardware support for MPEG4 encoding, Java hardware accelerator, and a number of connectivity peripherals including Bluetooth, FM Radio, WLAN, A-GPS and other modules.

    Part Number: PMB8876

    Sky77340

    Power Amplifier Module for Quad-Band GSM / EDGE

    SKY77340 PAM is designed in a compact form factor for quad-band cellular handsets comprising GSM850/900, DCS1800, PCS1900, supporting GMSK and linear EDGE modulation, and Class 12 GPRS multi-slot operation.
    Two separate HBT PA blocks supporting the GSM850/900 band and the DCS1800/PCS1900 band are fabricated onto InGaP die. Inputs and outputs are impedance-matched to 50 ohms, and a custom CMOS IC provides the internal MFC function and interface circuitry. The InGaP die, the silicon die, and the passive components are mounted on a multi-layer laminate substrate and the assembly is encapsulated with plastic overmold.



    So from that, we know the iPhone has at least two ARM CPUs, the ARM11 in the main Samsung SoC, and the ARM9 in the Infineon EDGE chip. I guess the latter chip also handles the on-board camera. I'm already suspecting that there might be a lot of duplication of capabilities in the hardware the iPhone supports.
