− | It looks like FIC is going to develop another device for OpenMoko quite soon, with the (code)name <b>HXD8</b>. On May 26th (GMT) Sean [http://lists.openmoko.org/pipermail/community/2007-May/005407.html confirmed] the existence of the device, said hardware support was almost done and cleverly told us to wait anxiously.

| + | [[Category:Hardware]] |
− | From the information found in the [https://svn.openmoko.org/trunk/doc/hardware/HXD8v011/ hardware documentation] and [https://svn.openmoko.org/trunk/src/target/kernel/patches/ kernel patches] parts of the subversion repositories, the following specifications can be predicted.

− | ===Processor===
| + | |
− | According to https://svn.openmoko.org/trunk/src/target/kernel/patches/s3c2440-nand-disable-hwecc.patch the HXD8 will feature an [http://www.samsung.com/Products/Semiconductor/common/product_list.aspx?family_cd=MSC0102 S3C2440], capable of running up to 400MHz. The features are the same as the [http://www.samsung.com/products/semiconductor/MobileSoC/ApplicationProcessor/ARM9Series/S3C2410/S3C2410.htm S3C2410] plus a camera interface.

− | ===Flash===
| + | |
− | According to a currently available hardware patch, the device supports 1 NAND Flash device of up to 4G. (uncertain about what kind of G that is. Could be 4Gb (which makes about 0,5GB), could be 4GB).
| + | |
− | | + | |
− | Some other patch implies that there is the possibility of connecting 3 NAND Flash chips.

− | | + | |
− | ===RAM===
| + | |
− | 128MB Random Access Memory, of which 2MB is used as a Framebuffer. https://svn.openmoko.org/trunk/src/target/u-boot/patches/uboot-hxd8.patch

− | ===LCD Module (LCM)===
| + | |
− | The HXD8 features a 480x272 pixel LCD (which is a widescreen (16:9) ratio) with PWM-controlled backlight.
| + | |
− | | + | |
− | ===Camera===
| + | |
− | The Omnivision OM7670 Camerachip Image Sensor, is a low-voltage, low-power CMOS camera chip, capable of operating at 30fps on VGA resolution.

− | ===Light Sensor===
| + | |
− | The HXD8 features a light sensor by TAOS Inc. (Texas Advanced Optoelectronic Solutions). It's either a [http://www.taosinc.com/product_detail.asp?cateid=4&proid=59 TLS2560] or a [http://www.taosinc.com/product_detail.asp?cateid=4&proid=60 TLS2561]. This light sensor will be included to measure ambient illuminance to control the LCM backlight illumination, or for exposure control for the camera (depends on location of the chip).
