Introduction
For cost sensitive applications, the NAND Flash controller allows the use of low-cost NAND Flash
devices to be used as primary or secondary non-volatile storage. The on-chip error correction code (ECC)
and parity checking circuitry of the NAND Flash controller frees the CPU for other tasks. WLAN,
Bluetooth and expansion options are provided through PCMCIA/CF, USB, and MMC/SD host controllers.
The device is packaged in a 289-pin MAPBGA.

Conventions
This document uses the following conventions:
OVERBAR is used to indicate a signal that is active when pulled low: for example, RESET.
Logic level one is a voltage that corresponds to Boolean true (1) state.
Logic level zero is a voltage that corresponds to Boolean false (0) state.
To set a bit or bits means to establish logic level one.
To clear a bit or bits means to establish logic level zero.
