Overview
Overview

The PCA9633 Demo Board demonstrates the NXP PCA9633 Fast Mode Plus 4-bit I²C LED Driver IC. Four LEDs are connected to the PCA9633 and through individual pulse width modulation (PWM) of each LED show different levels of intensity.

The board supports six different modes of operation including color wash and random color. The on-board Flash microcontroller is also user reprogrammable for endless variations of functionality. The USB-ICP, a small USB based ICP programmer that allows ICP programming of the P89LPC9103 and many other NXP microcontrollers from any PC with a USB port is also available from FDI.

PCA9633 Features
  • 1 MHz and 30mA output allows faster data updates and / or more capacitive busses
  • 4 Individually controlled 25mA open drain or push-pull outputs OFF, ON, DIM, or DIM with Global Control for LED dimming / blinking
  • /OE input pin also allows hardware dimming / blinking
  • Up to 7 address pins allows 128 I²C addresses
  • 4 software programmable I²C addresses allows controlling groups of devices with single software command sequence
  • If the battery is low, the red LED will flash every 3 seconds as a warning
