PCA9633 demonstration board OM6282
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
2
C demo-boards
to create an evaluation system.
The IC communicates to the host via the industry standard I
2
C-bus/SMBus port. The
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 I
2
C-bus is helpful but not required.
3.2 Static handling requirements
3.3 Minimum system requirements
•
PC Pentium 60 processor (or equivalent), 8 MB RAM, 10 MB of hard drive space
• One USB port (either 2.0 or 1.1 compatible)
• Windows 98SE, ME, 2000, XP, or Vista
• I2C 2005-1 demonstration board (OM6275)
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.
CAUTION
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.
