Bulk-Only Transport Specification. The USB port of the
NX2LP-Flex is connected to a host computer directly or through
the downstream port of a USB hub. The 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 CE# pins enable 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 enable
quick configuration of some features to decrease design effort
and increase time-to-market advantages.

Functional Description
■
Wireless LAN with NAND Flash storage
Cypress Semiconductor Corporation’s EZ-USB® NX2LP-Flex
(CY7C68033/CY7C68034) is a firmware-based, programmable
version of the EZ-USB NX2LP (CY7C68023/CY7C68024),
which is a fixed-function, 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 implementations. 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.

Functional Overview
USB Signaling Speed
NX2LP-Flex operates at two of the three rates defined in the USB
Specification Revision 2.0, dated April 27, 2000:
■
Full speed, with a signaling bit rate of 12 Mbps
■
High speed, with a signaling bit rate of 480 Mbps.
An on-chip PLL multiplies the 24-MHz oscillator up to 480 MHz,
as required by the transceiver/PHY, and internal counters divide
it down for use as the 8051 clock. The default 8051 clock
frequency is 12 MHz. The clock frequency of the 8051 can be
changed by the 8051 through the CPUCS register, dynamically

20 × PLL
The 8051 microprocessor embedded in the NX2LP-Flex has
256 bytes of register RAM, an expanded interrupt system and
three timer/counters.
8051 Clock Frequency
NX2LP-Flex has an on-chip oscillator circuit that uses an
external 24 MHz (±100 ppm) crystal with the following
characteristics:
■
Parallel resonant
■
Fundamental mode
■
500 W drive level
■
12 pF (5% tolerance) load capacitors.
12-pF capacitor values assumes a trace capacitance
of 3 pF per side on a four-layer FR4 PCA
Special Function Registers
Certain 8051 SFR addresses are populated to provide fast
access to critical NX2LP-Flex functions. These SFR additions
are shown in Table 1. Bold type indicates non-standard,
enhanced 8051 registers. The two SFR rows that end with ‘0’ and
‘8’ contain bit-addressable registers. The four I/O ports A–D use
the SFR addresses used in the standard 8051 for ports 0–3,
which are not implemented in NX2LP-Flex. Because of the faster
and more efficient SFR addressing, the NX2LP-Flex I/O ports are
not addressable in external RAM space (using the MOVX
instruction).

Buses
Normal Operation Mode
The NX2LP-Flex features an 8- or 16-bit ‘FIFO’ bidirectional data
bus, multiplexed on I/O ports B and D.
In normal operation mode, the NX2LP-Flex behaves as a
USB 2.0 Mass Storage Class NAND Flash controller. This
includes all typical USB device states (powered, configured, and
so on). The USB descriptors are returned according to the data
stored in the configuration data memory area. Normal read and
write access to the NAND Flash is available in this mode.
The default firmware image implements an 8-bit data bus in GPIF
master mode. It is recommended that additional interfaces
added to the default firmware image use this 8-bit data bus.
Enumeration
During the startup sequence, internal logic checks for the
presence of NAND Flash with valid firmware. If valid firmware is
found, the NX2LP-Flex loads it and operates according to the
firmware. If no NAND Flash is detected, or if no valid firmware is
found, the NX2LP-Flex uses the default values from internal
ROM space for manufacturing mode operation. The two modes
of operation are described in the section Normal Operation Mode
and Manufacturing Mode.

Start-up

No
Manufacturing Mode
In manufacturing mode, the NX2LP-Flex enumerates using the
default descriptors and configuration data that are stored in
internal ROM space. This mode enables for first time
programming of the configuration data memory area, and board
level manufacturing tests.
Default Silicon ID Values
To facilitate proper USB enumeration when no programmed
NAND Flash is present, the NX2LP-Flex has default silicon ID
values stored in ROM space. The default silicon ID values should
only be used for development purposes. Designers must use
their own Vendor ID for final products. A Vendor ID is obtained
through registration with the USB Implementor’s Forum
(USB-IF). If the NX2LP-Flex is used as a mass storage class
device, a unique USB serial number is required for each device
to comply with the USB Mass Storage class specification.
Cypress provides all the software tools and drivers necessary to
properly programme and test the NX2LP-Flex. Refer to the
documentation in the development kit for more information on
these topics.

NX2LP-Flex implements an autovector feature for INT2 and

(FIFO/GPIF) vectors. For more details, refer to the EZ-USB
Technical Reference Manual (TRM).

CY7C68033
CY7C68034
USB-Interrupt Autovectors
The main USB interrupt is shared by 27 interrupt sources. To
save the code and processing time normally required to identify
the individual USB interrupt source, the NX2LP-Flex provides a
second level of interrupt vectoring, called Autovectoring. When
a USB interrupt is asserted, the NX2LP-Flex pushes the program
counter to its stack and then jumps to address 0x0500; it expects
to find a ‘jump’ instruction to the USB Interrupt service routine
here.
Developers familiar with Cypress’s programmable USB devices
should note that these interrupt vector values differ from those
used in other EZ-USB microcontrollers. This is due to the
additional NAND boot logic that is present in the NX2LP-Flex
ROM space. Also, these values are fixed and cannot be changed
in the firmware.

If autovectoring is enabled (AV2EN = 1 in the INTSET-UP register), the NX2LP-Flex substitutes its INT2VEC byte. Therefore, if the
high byte (‘page’) of a jump-table address is preloaded at location 0x544, the automatically inserted INT2VEC byte at 0x545 directs
the jump to the correct address out of the 27 addresses within the page.

Reset and Wakeup
Reset Pin
The input pin RESET#, resets the NX2LP-Flex when asserted.
This pin has hysteresis and is active LOW. When a crystal is
used as the clock source for the NX2LP-Flex, the reset period
must enable the stabilization of the crystal and the PLL. This
reset period should be approximately 5 ms after VCC has
reached 3.0V. If the crystal input pin is driven by a clock signal,
the internal PLL stabilizes in 200 s after VCC has reached
3.0 V[1]. Figure 5 shows a POR condition and a reset applied
during operation. A POR is defined as the time reset is asserted
while power is being applied to the circuit. A powered reset is
defined to be when the NX2LP-Flex has previously been
powered on and operating and the RESET# pin is asserted.
For more information on power on reset implementation for the
EZ-USB family of products, refer to the application note Guide to
a Successful EZ-USB® FX2LP™ Hardware Design.

The 8051 puts itself and the rest of the chip into a power down
mode by setting PCON.0 = 1. This stops the oscillator and PLL.
When WAKEUP is asserted by external logic, the oscillator
restarts, after the PLL stabilizes, and then the 8051 receives a
The second wakeup pin, WU2, can also be configured as a GPIO
pin. This enables a simple external R-C network to be used as a

Endpoints 0 and 1 are the same for every configuration. Endpoint
0 is the only control endpoint, and endpoint 1 can be either bulk
or interrupt. The endpoint buffers can be configured in any 1 of
the 12 configurations shown in the vertical columns. When
operating in full speed bulk mode, only the first 64 bytes of each
buffer are used. For example, in high speed the max packet size
is 512 bytes, but in full speed it is 64 bytes. Even though a buffer
is configured to be a 512 byte buffer, in full speed only the first
64 bytes are used. The unused endpoint buffer space is not
available for other operations. The following is an example
endpoint configuration:
EP2–1024 double buffered; EP6–512 quad buffered (column 8

External FIFO Interface
GPIF and FIFO Clock Rates
Architecture
An 8051 register bit selects one of two frequencies for the
internally supplied interface clock: 30 MHz and 48 MHz. A bit
within the IFCONFIG register inverts the IFCLK signal.
The NX2LP-Flex slave FIFO architecture has eight 512-byte
blocks in the endpoint RAM that directly serve as FIFO
memories, and are controlled by FIFO control signals (such as
SLCS#, SLRD, SLWR, SLOE, PKTEND, and flags).
In operation, some of the eight RAM blocks fill or empty from the
SIE, while the others are connected to the I/O transfer logic. The
transfer logic takes two forms: the GPIF for internally generated
control signals or the slave FIFO interface for externally
controlled transfers.
Master/Slave Control Signals
The NX2LP-Flex endpoint FIFOS are implemented as eight
physically distinct 256 × 16 RAM blocks. The 8051/SIE can
switch any of the RAM blocks between two domains, the USB
(SIE) domain and the 8051-I/O Unit domain. This switching is
done virtually instantaneously, giving essentially zero transfer
time between ‘USB FIFOS’ and ‘Slave FIFOS’. Since they are
physically the same memory, no bytes are actually transferred
between buffers.
At any time, some RAM blocks are filling/emptying with USB data
under SIE control, while other RAM blocks are available to the
8051 and/or the I/O control unit. The RAM blocks operate as
single-port in the USB domain and dual-port in the 8051-I/O
domain. The blocks can be configured as single, double, triple,
or quad buffered as previously shown.
The I/O control unit implements either an internal-master (M for
master) or external-master (S for Slave) interface.
In master (M) mode, the GPIF internally controls FIFOADR[1:0]
to select a FIFO. The two RDY pins can be used as flag inputs
from an external FIFO or other logic if desired. The GPIF can be
run from an internally derived clock (IFCLK), at a rate that
transfers data up to 96 Megabytes/s (48 MHz IFCLK with 16-bit
interface).
In slave (S) mode, the NX2LP-Flex accepts an internally derived
clock (IFCLK, max. frequency 48 MHz) and SLCS#, SLRD,
SLWR, SLOE, PKTEND signals from external logic. Each
endpoint can individually be selected for byte or word operation
by an internal configuration bit and a Slave FIFO output enable
signal SLOE enables data of the selected width. External logic
must ensure that the output enable signal is inactive when writing
data to a slave FIFO. The slave interface must operate
asynchronously, where the SLRD and SLWR signals act directly
as strobes, rather than a clock qualifier as in a synchronous
mode. The signals SLRD, SLWR, SLOE and PKTEND are gated
by the signal SLCS#.
Document Number: 001-04247 Rev. *Q
The default NAND firmware image implements a 48 MHz
internally supplied interface clock. The NAND boot logic uses the
same configuration to implement 100-ns timing on the NAND bus
to support proper detection of all NAND Flash types.
GPIF
The GPIF is a flexible 8- or 16-bit parallel interface driven by a
user-programmable finite state machine. It enables the
NX2LP-Flex to perform local bus mastering and can implement
a wide variety of protocols such as 8-bit NAND interface, printer
parallel port, and Utopia. The default NAND firmware and boot
logic uses GPIF functionality to interface with NAND Flash.
The GPIF on the NX2LP-Flex features three programmable
control outputs (CTL) and two general purpose ready inputs
(RDY). The GPIF data bus width can be 8 or 16 bits. Because
the default NAND firmware image implements an 8-bit data bus
and up to eight chip enable pins on the GPIF ports, it is
recommended that designs based upon the default firmware
image also use an 8-bit data bus.
Each GPIF vector defines the state of the control outputs and
determines what state a ready input (or multiple inputs) must be
before proceeding. The GPIF vector can be programmed to
advance a FIFO to the next data value, advance an address, and
so on. A sequence of the GPIF vectors make up a single
waveform that is executed to perform the desired data move
between the NX2LP-Flex and the external device.
Three Control OUT Signals
The NX2LP-Flex exposes three control signals, CTL[2:0]. CTLx
waveform edges can be programmed to make transitions as fast
as once per clock (20.8 ns using a 48 MHz clock).
Two Ready IN Signals
The 8051 programs the GPIF unit to test the RDY pins for GPIF
branching. The 56-pin package brings out two signals, RDY[1:0].
Long Transfer Mode
In GPIF master mode, the 8051 appropriately sets GPIF
transaction count registers (GPIFTCB3, GPIFTCB2, GPIFTCB1,
or GPIFTCB0) for unattended transfers of up to 232 transactions.
The GPIF automatically throttles data flow to prevent underflow
or overflow until the full number of requested transactions
complete. The GPIF decrements the value in these registers to
represent the current status of the transaction.

CY7C68033
CY7C68034
ECC Generation[5]
The NX2LP-Flex can calculate error correcting codes (ECCs) on
data that passes across its GPIF or slave FIFO interfaces. There
are two ECC configurations:
■
Two ECCs, each calculated over 256 bytes (SmartMedia
Standard)
■
One ECC calculated over 512 bytes.
The following two ECC configurations are selected by the ECCM
bit. The ECC can correct any one-bit error or detect any two-bit
error.
ECCM = 0
Two 3-byte ECCs, each calculated over a 256-byte block of data.
This configuration conforms to the SmartMedia Standard and is
used by both the NAND boot logic and default NAND firmware
image.
When any value is written to ECCRESET and data is then
passed across the GPIF or slave FIFO interface, the ECC for the
first 256 bytes of data is calculated and stored in ECC1. The ECC
for the next 256 bytes of data is stored in ECC2. After the second
ECC is calculated, the values in the ECCx registers do not
change until ECCRESET is written again, even if more data is
subsequently passed across the interface.
ECCM = 1
One 3-byte ECC calculated over a 512-byte block of data.
When any value is written to ECCRESET and data is then
passed across the GPIF or slave FIFO interface, the ECC for the
first 512 bytes of data is calculated and stored in ECC1; ECC2
is unused. After the ECC is calculated, the value in ECC1 does
not change until ECCRESET is written again, even if more data
is subsequently passed across the interface
Autopointer Access
NX2LP-Flex provides two identical autopointers. They are
similar to the internal 8051 data pointers, but with an additional
feature: they can optionally increment after every memory
access. Also, the autopointers can point to any NX2LP-Flex
register or endpoint buffer space.
I2C Controller
NX2LP has one I2C port that the 8051, once running uses to
control external I2C devices. The I2C port operates in master
mode only. The I2C post is disabled at startup and only available
for use after the initial NAND access.
I2C Port Pins
The I2C pins SCL and SDA must have external 2.2-k pull up
resistors even if no EEPROM is connected to the NX2LP.
I2C Interface General-Purpose Access
The 8051 can control peripherals connected to the I2C bus using
the I2CTL and I2DATA registers. NX2LP provides I2C master
control only and is never an I2C slave.
Note
5. To use the ECC logic, the GPIF or Slave FIFO interface must be configured for byte-wide operation.

Pin Assignments
Figure 9 and Figure 10 on page 16 identify all signals for the
56-pin NX2LP-Flex package.
Three modes of operation are available for the NX2LP-Flex: Port
mode, GPIF Master mode, and Slave FIFO mode. These modes
define the signals on the right edge of each column in Figure 9.
The right-most column details the signal functionality from the
default NAND firmware image, which actually utilizes GPIF
Master mode. The signals on the left edge of the ‘Port’ column
are common to all modes of the NX2LP-Flex. The 8051 selects
the interface mode using the IFCONFIG[1:0] register bits. Port
mode is the power-on default configuration.
Figure 10 on page 16 details the pinout of the 56-pin package
and lists pin names for all modes of operation. Pin names with
an asterisk (*) feature programmable polarity.

8051 is in suspend and WU2EN = 1, a transition on this pin starts
up the oscillator and interrupts the 8051 to allow it to exit the suspend
mode. Asserting this pin inhibits the chip from suspending, if
WU2EN = 1.
LED2# is the chip activity indicator LED sink pin.

Figure 17 shows the timing relationship of the SLAVE FIFO
signals during an asynchronous FIFO read. It shows a single
read followed by a burst read.
■
The data that is driven, after asserting SLRD, is the updated
data from the FIFO. This data is valid after a propagation delay
of tXFD from the activating edge of SLRD. In Figure 17, data N
is the first valid data read from the FIFO. For data to appear on
the data bus during the read cycle (that is SLRD is asserted),
SLOE MUST be in an asserted state. SLRD and SLOE can
also be tied together.
■
At t = 0 the FIFO address is stable and the SLCS signal is
asserted.
■
At t = 1, SLOE is asserted. This results in the data bus being
driven. The data that is driven on to the bus is previous data,
it data that was in the FIFO from a prior read cycle.
The same sequence of events is also shown for a burst read
marked with T = 0 through 5.
At t = 2, SLRD is asserted. The SLRD must meet the minimum
active pulse of tRDpwl and minimum deactive pulse width of
tRDpwh. If SLCS is used then, SLCS must be in asserted with
SLRD or before SLRD is asserted (that is the SLCS and SLRD
signals must both be asserted to start a valid read condition).
Note In burst read mode, during SLOE is assertion, the data bus
is in a driven state and outputs the previous data. After SLRD is
asserted, the data from the FIFO is driven on the data bus (SLOE
must also be asserted) and then the FIFO pointer is
incremented.

PKTEND
Figure 19 shows the timing relationship of the SLAVE FIFO write
in an asynchronous mode. The diagram shows a single write
followed by a burst write of three bytes and committing the
4-byte-short packet using PKTEND.
The FIFO flag is also updated after tXFLG from the deasserting
edge of SLWR.
■
At t = 0 the FIFO address is applied, insuring that it meets the
setup time of tSFA. If SLCS is used, it must also be asserted
(SLCS may be tied low in some applications).
■
At t = 1 SLWR is asserted. SLWR must meet the minimum
active pulse of tWRpwl and minimum de-active pulse width of
tWRpwh. If the SLCS is used, it must be in asserted with SLWR
or before SLWR is asserted.
Note In the burst write mode, after SLWR is deasserted, the data
is written to the FIFO and then the FIFO pointer is incremented
to the next byte in the FIFO. The FIFO pointer is post
incremented.
■
At t = 2, data must be present on the bus tSFD before the
deasserting edge of SLWR.
At t = 3, deasserting SLWR causes the data to be written from
the data bus to the FIFO and then increments the FIFO pointer.
The same sequence of events are shown for a burst write and is
indicated by the timing marks of T = 0 through 5.
As shown in Figure 19 after the four bytes are written to the FIFO
and SLWR is deasserted, the short 4-byte packet can be
committed to the host using the PKTEND. The external device
should be designed to not assert SLWR and the PKTEND signal
at the same time. It should be designed to assert the PKTEND
after SLWR is deasserted and met the minimum de-asserted
pulse width. The FIFOADDR lines are to be held constant during
the PKTEND assertion.

28. Dashed lines denote signals with programmable polarity.

PCB Layout Recommendations
■
Follow these recommendations [29] to ensure reliable high
performance operation:
No vias should be placed on the DPLUS or DMINUS trace
routing unless absolutely necessary.
■
Isolate the DPLUS and DMINUS traces from all other signal
traces as much as possible.
■
At least a four-layer impedance controlled boards is
recommended to maintain signal quality.
■
Specify impedance targets (ask your board vendor what they
can achieve) to meet USB specifications.
■
To control impedance, maintain trace widths and trace spacing.
■
Minimize any stubs to avoid reflected signals.
■
Connections between the USB connector shell and signal
ground must be done near the USB connector.
■
Bypass/flyback
recommended.
■
DPLUS and DMINUS trace lengths should be kept to within
2 mm of each other in length, with preferred length of
20–30 mm.
■
Maintain a solid ground plane under the DPLUS and DMINUS
traces. Do not allow the plane to be split under these traces.

Quad Flat Package No Leads (QFN) Package
Design Notes
Electrical contact of the part to the printed circuit board (PCB) is
made by soldering the leads on the bottom surface of the
package to the PCB. Therefore, special attention is required to
the heat transfer area below the package to provide a good
thermal bond to the circuit board. Design a copper (Cu) fill into
the PCB as a thermal pad under the package. Heat is transferred
from the NX2LP-Flex to the PCB through the device’s metal
paddle on the bottom side of the package. It is then conducted
from the PCB’s thermal pad to the inner ground plane by a
5 × 5 array of vias. A via is a plated through hole in the PCB with
a finished diameter of 13 mil. The QFN’s metal die paddle must
be soldered to the PCB’s thermal pad. Solder mask is placed on
the board top side over each via to resist solder flow into the via.
The mask on the top side also minimizes outgassing during the
solder reflow process.

Figure 21 displays a cross-sectional area underneath the package. The cross section is of only one via. The solder paste template
needs to be designed to enable at least 50% solder coverage. The thickness of the solder paste template should be 5 mil. It is
recommended that ‘No Clean’ type 3 solder paste is used for mounting the part. Nitrogen purge is recommended during reflow.
Figure 22 is a plot of the solder mask pattern and Figure 23 displays an X-Ray image of the assembly (darker areas indicate solder).
