Creative Zen X-Fi2


Overview

This is the page for the Creative Zen X-Fi2 device.

Hardware

The Creative Zen X-Fi2 features a resistive touch screen with 3 hardware buttons: power, select and reset. The following chips can be found on the PCB:
  • STMP3780 (see SigmaTelSTMP3xxx), see the SansaFuzePlus page for more information (it's the same SoC, also called i.MX 233)
  • one or more Hynix
 H27UCG8UDMYR? flash chips (see Hynix part decoder)
  • one STFM1000 fm tuner chip, there is no available datasheet due to a patent but the freescale i.MX linux source code has a driver for it (search for stfm1000 linux on google). The product brief can be found on Freescale website
  • one Hynix
 H5M851620FA? 64Mb Mobile DDR (see Hynix part decoder)
  • the LCD controller seems to be (or be compatible with) the Renesas R61509 for which the datasheet is available here
  • a very hard to read chip marked 263 7x60, which is probably a Freescale MMA7660FC? 3-Axis Accelerometer, the datasheet can be found here

Variants

It seems from the OF analysis that there are two variants of the hardware. One would use raw NAND as internal storage and the other would use SD/eMMC. This is still to be confirmed.

Pins

Here is a list of all the pins used by the OF. Pins are of form BxPyy where x is the bank and yy the number within the bank. Direction only applies to GPIO.

Vendor-Specific SCSI

When plugged in UMS mode, the Creative Zen X-Fi2 support a number of vendor-specific SCSI commands used to identify and upgrade it. The following table summarizes those command. Some might apply to other devices of the Creative ZEN family.

The CDB (Command Data Block) always start with 0xC0 for read transfers and 0xC1 for write transfers. The second byte of the CDB is the actual command and the third byte is the type (when it applies).
