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 through 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 interfaces and both common NAND page sizes of 512 and 2k bytes. Eight chip enable pins allow the 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 design requirements.
