years.
Nand FLASH is a startup device, when startup the main chip S3C6410 automatically copy
the former 8K bites code in Nand Flash to the chip’s internal Stepping Stone room for
running. After initialization configuration, the chip jumps to start address of Kernel to run
the OS. Below picture shows the schematic drawing of Nand Flash:
3.2. DDR RAM
The IDEA6410 adopts two Samsung K4X51163PC 64M Bytes Mobile DDR RAM with
266MHz. They are small BGA package in order to save the room of the board, also is to
use same length circuit line on the PCB for guaranteeing the board running with high
speed and stably.
3.3. Nor Flash
IDEA6410 adopts ARM AM29LV160DB Nor Flash, the chip S3C6410 maximum supports
27 pieces address singals A0-A26, in which A20-A26 is reused with DDR data signals
D20-D26. As IDEA6410 adopted 32bit DDR RAM, there are only 19 pieces line A1-A19 for
NOR Flash use. Nor Flash addressing range is 1M Bytes.
Nor Flash can be configured as startup device, it adopts 16-bit SROM startup mode.
Below picture shows the schematic drawing of NOR Flash:
