Abstract The OM6282 is an add-on to NXP’s I2C 2005 -1 demo board. This daughter
board makes it easy to test and design with the PCA9633, a 4-bit Fast-mode
Plus (Fm+) LED driver. These boards, along with the I2CUSB Lite GUI
(PC based), provide an easy to use evaluation platform.

1. Introduction
The PCA9633 evaluation board features LEDs for color mixing, blinking and dimming
demonstrations. A graphical interface allows the user to easily explore the different
functions of the driver. The board can be connected in series with other I
to create an evaluation system.
The IC communicates to the host via the industry standard I
evaluation software runs under MicroSoft Windows PC platform.
2. Features
• A complete evaluation platform for the PCA9633 4-bit LED driver
• Easy to use GUI based software demonstrates the capabilities of the PCA9633
• On-board LEDs for visual experience
• Convenient test points for easy scope measurements and signal access
• USB interface to the host PC
• No external power supply required

3. Getting started
3.1 Assumptions
Familiarity with the I2C-bus is helpful but not required.
3.2 Static handling requirements
CAUTION
3.3 Minimum system requirements
•
• One USB port (either 2.0 or 1.1 compatible)
• Windows 98SE, ME, 2000, XP, or Vista
• I2C 2005-1 demonstration board (OM6275)
This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken
during transport and handling. You must use a ground strap or touch the PC case or other
grounded source before unpacking or handling the hardware.
PC Pentium 60 processor (or equivalent), 8 MB RAM, 10 MB of hard drive space
3.4 Power requirements
The NXP demonstration board I2C 2005-1 and OM6282 hardware obtain power from the
PC USB port. Care should be taken not to exceed the USB port current capabilities.

4. Installation
4.1 I2C 2005-1 board and WIN-12CUSB Lite software
The OM6282 is a daughter card to the OM6275 I2C 2005-1 demo board. You may
download the WIN-I2CUSB Lite Software, the OM6275 user manual UM10206, and find
ordering information at the NXP web site
http://www.standardics.nxp.com/support/boards/i2c20051/
4.2 OM6282 connection to I2C 2005-1 board
The I2C 2005-1 demo board should be discon ne ct ed fro m yo ur PC before mo un tin g th e
OM6281 board on to it. The OM6282 board has a 9 -pin female conne ctor that connect s to
the JP1 male connector on the I2C 2005-1 board.
With both boards facing you, connect the OM6282 board to the I2C 2005-1 board before
connecting the USB cable. Once the board is connected, connect the USB cable an d start
the WIN-I2CUSB Lite software. You are now ready to evaluate the PCA9633.
