• Some (not particularly useful) internal photos of the LifeDrive are available (PDF) from the FCC filing search. The LifeDrive's FCC ID is O3W830.

• These pictures are not of the final shipped version, note for example the 5 GB Seagate drive in the images.

• Small photo of a backless regular LifeDrive.

• German forum thread about replacing the microdrive with a flash card containing several images.

Specifications

• General Device Specification

• This device was produced by Palm

• Product page

• PDF

• CPU

• Intel 416mhz XScale PXA270 (rev 7)

• Product page for PXA27x Family

• Datasheet (PDF) for the PXA270

• ROM

• 4M-bit (512k) Macronix 29LV400BXBC-76 that contains bootloader

• RAM

• 32MB (256Mbit) Infineon Mobile-RAM HYB25L256160AC-7.5

• Datasheet (PDF)

• 4MB used as HDD cache by PalmOS

• Hard Disk

• Hitachi 4GB microdrive

• 64MB "program memory" partition acts like the RAM on the earlier Palms.

• 3.85GB data storage appears as an expansion card to Palm OS programs.

• Compact Flash connected directly to CPU.

• Intel: Connecting the Intel® PXA27x Processor Family to a Hard-Disk Drive via the VLIO Memory Interface (PDF)

• PalmOS seems to operate it in True-IDE mode. Not sure whether this is hard wired or if we can change it. We need to power cycle the HDD while holding OE non-grounded.

• Display

• Sharp LQ038J7DH53 320x480 transreflective TFT.

• Touchscreen

• Wolfson Microelectronics WM9712 AC'97 and Touchpanel codec

• Product page

• Datasheet (PDF)

• SD/SDIO/MMC

• Uses the PXA270's internal controller.

• Wi-fi (802.11b)

• SyChip 6061

• Brochure (PDF)

• Linux is listed as supported OS. Could it be a closed source driver?

• SyChip has been bought by muRata Mfg. Co. Ltd. on 13th of April 2006.

• There is a package in the ROM called 8305fw which appears to be for the Wi-fi. It contains the string "8305 fw 03-70-51A 2005/02/02/60232".

• SyChip WLAN6061EB is based on Marvell Libertas 88W8305 chipset

• Bluetooth

• BCM2035B1

• Product Brief (PDF)

• According to product brief, probably two GPIO pins BT_WAKE (out) and HOST_WAKE (in).

• Probably uses the PXA270's BTUART.

• Palm Multi Connector

• 18 pin connector as used in the Tungsten T5 and Treo 650

• Described in the Developer Guide (PDF)

• Serial pins (this is 3.3v logic, so don't directly wire to a PC serial port, you'll need to level shift):

• 5 DGND

• 7 TXD

• 8 RXD

• That's counting from the side with the power connector and counting pin 1 as the little rectangular cable shield hole.

• USB EZ-USB SX2(TM) High-Speed USB Interface Device

• CY7C68001 EZ-USB SX2 USB 2.0

• Product Page

• Datasheet REV.*B (PDF)

• Datasheet REV.*H (PDF)

• Errata (PDF)
