The ‘Gaming suitcase demo system’ is a demonstration kit for I2C-bus controllers, LED
drivers and stepper motors. This demonstration kit and software provide an overview of
the capabilities of its components and is easy to use.
The PCU9669 is a new generation I
(UFm)’ which is defined in latest I
MCU’s parallel bus and 3 ch annel I
PCU9669 (and its family) has a large buffer to manage transfers with ultra low CPU load.
The PCU9955 is a constant current LED driver.
The PCU9655 is a voltage switch LED driver.
Sample code is available for the demo kit. The processor is an NXP LPC2214 ARM
microcontroller. The LPC12214 supports to build a feature-rich demo with its high
capability.
This evaluation board kit is populated with the following:

• PCU9669 motherboard with ARM7 LPC2214 microcontroller
• One 160-white-LED board (PCA9955)
• Six 4-RGB-LED boards (PCU9655)
• One 8-white-LED board (PCU9655)
• Two 5-stepper motor boards (PCA9629)
• Universal power supply
(1) Channel 0 (J11) of PCU9669 is an Fm+ channel. Normal I2C-bus devices can be connected on this channel.
(2) Channel 1 (J12) and channel 2 (J13) of PCU9669 are UFm channels and are used for the Ultra-Fast mode LED controllers.
Familiarity with the I2C-bus is helpful but not required.

CAUTION
UM10563
Gaming suitcase demo system
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.
