Migrating From EZ-USB FX2™ to EZ-USB FX2LP™
www.cypress.com Document No. 001-42079 Rev. *D 7
The additional registers for this function are:
Configuration register
(256/512)
Reset ECC-byte registers to
zero
This is the second eight bits of
the line parity on the first 256-
byte block or the 512-byte
block.
Lower eight bits of line parity
on first 256-byte block or lower
eight bits of line parity on 512-
byte block.
This is the 6-bit column parity
on first 256-byte block or 6-bit
column parity on and upper
two bits of line parity for 512-
byte block.
This is the second eight bits of
the line parity. on the second
256-byte block
Lower eight bits of line parity
on second 256-byte block
This is the 6-bit column parity
on the second 256-byte block
(For column and line parity see Smart media
Specification.) See Technical Reference Manual for
check/correct sample code.
Package Changes
Additional options have been made available in the
packaging of the FX2LP part. Additional configurations are
available in the 56-pin packages. These configurations
allow for two additional GPIO pins. These parts are the
part number CY7C68015A/CY7C68016A, available in both
a QFN and a SSOP package. In CY7C68015A/16A,
IFCLK and CLKOUT pins are replaced by PE0 and PE1
respectively. The effect of this change on the design has
to be considered while replacing FX2 (56-pin QFN
package) with CY7C68015A/16A. As in FX2, all FX2LP
parts are available in lead-free packages. The following
table lists the FX2 parts and the respective FX2LP part
that may be used to replace the FX2. Besides the
packages that are specified, FX2LP also has a VFBGA
56-pin package (CY7C68013A-56BAXC and
CY7C68014A-56BAXC).
CY7C68014A and CY7C68016A are Ideal for battery-
powered applications as they have an ultra-low suspend
current of 100 A (typical). CY7C68013A and
CY7C68015A, that have a low suspend current of 300 A
(typical), are ideal for non-battery powered (self or bus
powered) applications.

Development Tool
The EZ-USB FX2LP has a development kit similar to that
of the EX-USB FX2. The part number for this kit is
CY3684. The development kit for the FX2LP contains a
development board, cables, documentation and a
development CD.
The CD has electronic copies of the Technical Reference
Manual, the data sheet, schematics and gerbers for the
development board, firmware examples, drivers
(CyUSB.sys)and evaluation version of the Keil’s Vision2
Compiler.
