First Generation System
Physical dimensions:
* Dimensions: 193mm à 229mm à 64mm (as of 3/27/06âsubject to
change)
* Weight: Less than 1.5 KG (target onlyâsubject to change)
* Configuration: Convertible laptop with pivoting, reversible
display; dirt- and moisture-resistant system enclosure
Core electronics:
* CPU: AMD Geode [EMAIL PROTECTED]
* CPU clock speed: 400 Mhz
* Compatibility: X86/X87-compatible
* Chipset: AMD CS5536 South Bridge
* Graphics controller: Integrated with Geode CPU; unified memory
architecture
* Embedded controller: Based on ENE 3920
* DRAM memory: 128MB dynamic RAM
* Data rate: Dual â DDR266 â 133 Mhz
* BIOS: 512KB SPI-interface flash ROM; LinuxBIOS open-source BIOS
* Mass storage: 512MB SLC NAND flash
* Drives: No rotating media
Display:
* Liquid-crystal display: 7.5â Dual-mode TFT display
* Viewing area: 151.6 mm à 113.4 mm
* Resolution: 1200 (H) Ã 900 (V) resolution (200 dpi)
* Mono display: High-resolution, reflective monochrome mode
* Color display: Standard-resolution, quincunx-sampled, transmissive
color mode
* Special "DCON" chip, that enables deswizzling and anti-aliasing in
color mode, while enabling the display to remain live with the processor
suspended. Since we will always be running the frame buffer at 1200x900
resolution, the color resolution is lower, but exactly how this works
out in effective resolution is complex. Mary Lou Jepsen is planning a
document to explain the effective resolution, which is higher than if we
simply reduced the size of the frame buffer and used the red, green and
blue channels.
Integrated peripherals:
* Keyboard: 80 keys, 1.2mm stroke; sealed rubber-membrane key-switch
assembly
* Cursor-control keys: Dual five-key cursor-control pads; four
directional keys plus Enter
* Touchpad: Dual capacitance/resistive touchpad; supports
written-input mode; vendor to be selected June 10
* Audio: Analog Devices AD1888, AC97-compatible audio codec; stereo,
with dual internal speakers; monophonic, with internal microphone
* Wireless: Marvell 83W8388, 802.11b/g compatible; dual adjustable,
rotating coaxial antennas; supports diversity reception
* Status indicators: Power, battery, WiFi; visible lid open or
closed
External connectors:
* Power: 2-pin DC-input, 10 to 25 V, -23 to -10 V
* Line output: Standard 3.5mm 3-pin switched stereo audio jack
* Microphone: Standard 3.5mm 2-pin switched mono microphone jack;
selectable sensor-input mode
* Expansion: 3 Type-A USB-2.0 connectors
* Maximum power: 500 mA (total)
Battery:
* Pack type: 5 Cells, 6V series configuration
* Fully-enclosed âhardâ case; user removable
* Capacity: 22.8 Watt-hours
* Cell type: NiMH
* Pack protection: Integrated pack-type identification
* Integrated thermal sensor
* Integrated polyfuse current limiter
* Cycle life: Minimum 2,000 charge/discharge cycles (to 50% capacity
of new, IIRC).
BIOS/loader:
* LinuxBIOS is our intended BIOS for production units.
Environmental specifications:
* Temperature: somewhere in between typical laptop requirements and
Mil spec; exact values have not been settled
* Humidity: Similar attitude to temperature. When closed, the unit
should seal well enough that children walking to and from school need
not fear rainstorms or dust.
* Maximum altitude: -15m to 3048m (14.7 to 10.1 psia) (operating),
-15m to 12192m (14.7 to 4.4 psia) (non-operating
* Shock 125g, 2ms, half-sine (operating) 200g, 2ms, half-sine
(non-operating)
* Random vibration: 0.75g zero-to-peak, 10Hz to 500Hz, 0.25 oct/min
sweep rate (operating); 1.5g zero-to-peak, 10Hz to 500Hz, 0.5 oct/min
sweep rate (nonoperating)
* 2mm plastic walls (1.3mm is typical for most systems).
Regulatory requirements:
* The usual US and EU EMI/EMC requirements will be met.
* The laptop and all OLPC-supplied accessories will be fully UL and
is RoHS compliant.
