Introduction
The EZ-USB NX2LP
(
NX2LP
)
implements a USB 2.0 NAND
Flash controller. This controller adheres to the
Mass Storage
Class Bulk-Only Transport Specification
. The USB port of the
NX2LP is connected to a host computer directly or via the
downstream port of a USB hub. Host software issues
commands and data to the NX2LP and receives status and
data from the NX2LP using standard USB protocol.
The NX2LP supports industry leading 8-bit NAND Flash inter-
faces and both common NAND page sizes of 512 and 2k
bytes. Eight chip enable pins allowthe NX2LP to be connected
to up to eight single- or four dual-device NAND Flash chips.
Certain NX2LP features are configurable, enabling the NX2LP
to meet the needs of different designs’ requirements.
