Default NAND Firmware Features
Because
Flash-based USB mass storage applications, a default
firmware image is included in the development kit with the
following features:
The default firmware image 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-Flex 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-Flex and receives status
and data from the NX2LP-Flex using standard USB protocol.
The default firmware image supports industry leading 8-bit
NAND Flash interfaces and both common NAND page sizes
of 512 and 2k bytes. Up to eight chip enable pins allow the
NX2LP-Flex to be connected to up to eight single- or four
dual-die NAND Flash chips.
Complete source code and documentation for the default
firmware image are included in the NX2LP-Flex development
kit to enable customization for meeting design requirements.
Additionally, compile options for the default firmware allow for
• High (480-Mbps) or full (12-Mbps) speed USB support
• Both common NAND page sizes supported
• 12 configurable general-purpose I/O (GPIO) pins
• Industry standard ECC NAND Flash correction
• Industry standard (SmartMedia) page management for
• 8-bit NAND Flash interface support
• Support for 30-ns, 50-ns, and 100-ns NAND Flash timing
• Complies with the USB Mass Storage Class Specification
— 512 bytes for up to 1 Gb capacity
— 2K bytes for up to 8 Gb capacity
— 2 dedicated chip enable (CE#) pins
— 6 configurable CE#/GPIO pins
— 4 dedicated GPIO pins

Overview
Cypress Semiconductor Corporation’s (Cypress’s) EZ-USB
NX2LP-Flex (CY7C68033/CY7C68034) is a firmware-based,
programmable
(CY7C68023/CY7C68024),
low-power USB 2.0 NAND Flash controller. By integrating the
USB 2.0 transceiver, serial interface engine (SIE), enhanced
8051 microcontroller, and a programmable peripheral
interface in a single chip, Cypress has created a very
cost-effective solution that enables feature-rich NAND
Flash-based applications.
The ingenious architecture of NX2LP-Flex results in USB data
transfer rates of over 53 Mbytes per second, the
maximum-allowable USB 2.0 bandwidth, while still using a
low-cost 8051 microcontroller in a small 56-pin QFN package.
Because it incorporates the USB 2.0 transceiver, the
NX2LP-Flex is more economical, providing a smaller footprint
solution than external USB 2.0 SIE or transceiver implemen-
tations. With EZ-USB NX2LP-Flex, the Cypress Smart SIE
handles most of the USB 1.1 and 2.0 protocol, freeing the
embedded microcontroller for application-specific functions
and decreasing development time while ensuring USB
compatibility.
The
Master/Slave Endpoint FIFO (8- or 16-bit data bus) provide an
easy and glueless interface to popular interfaces such as
UTOPIA, EPP, I
Applications
The NX2LP-Flex allows designers to add extra functionality to
basic NAND Flash mass storage designs, or to interface them
with other peripheral devices. Applications may include:
• NAND Flash-based GPS devices
• NAND Flash-based DVB video capture devices
• Wireless pointer/presenter tools with NAND Flash storage
• NAND Flash-based MPEG/TV conversion devices
• Legacy conversion devices with NAND Flash storage
• NAND Flash-based cameras
• NAND Flash mass storage device with biometric (e.g.,
• Home PNA devices with NAND Flash storage
• Wireless LAN with NAND Flash storage
• NAND Flash-based MP3 players
• LAN networking with NAND Flash storage
