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.

Pin	Dir	Comment
B0P10	IN	Acceleretor INT line
B0P11	IN	Power button (active low)
B0P12	OUT	Unknown use
B0P14	IN	Select button (active low)
B0P{30,31}		I2C lines
B1P{00-17}	lcd_d{0-17}
B1P18	lcd_reset
B1P19	lcd_rs
B1P20	lcd_wr
B1P21	lcd_cs
B1P22	lcd_dotclk	unused?
B1P23	lcd_enable
B1P24	lcd_vsync	unused?
