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.
■ Industry Standard (SmartMedia) Page Management for Wear
Leveling Algorithm, Bad Block Handling, and Physical to
Logical management
■ Supports 8-bit NAND Flash Interfaces
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 allow the NX2LP to be connected to up to
eight single or four dual device NAND Flash chips.
■ Supports 30 ns, 50 ns, and 100 ns NAND Flash Timing
■ Complies with USB Mass Storage Class Specification rev 1.0
Certain NX2LP features are configurable, enabling the NX2LP to
meet the needs of different design requirements.
■ CY7C68024 Complies with USB 2.0 Specification for
Bus-Powered Devices (TID# 40460274)
