Alcatel Web Touch One – design information

System information

During writing the documentation there was no entire phone available for the author but only CPU board, LCD with touchpad and backlight power supply. That is reason why some information are incomplete, especially about signals provided from externals boards.

CPU board is populated with:

•

PowerPC processor running on 66MHz (XPC823ZT66A),

•

32MB of SDRAM configured in two 32-bit banks,

•

2MB of flash memory configured in 32-bit,

•

8MB of NAND flash memory,

•

33.6kbit/s Rockwell modem,

• analogue parts used mainly for voice processing.

LCD is tied with CPU board through 22-pin connector; touch panel located on LCD joins with CPU board by 4-pin connector. For board programming JTAG/BDM connector may be used. Detailed connector description is provided in chapter “programming the board”. Below pictures shows both sides of the CPU board. All chips were numbered to provide easy reference in documentation.
