16-bit I²C-bus LED dimmer

The PCA9532 is a 16-bit I²C-bus and SMBus I/O expander optimized for dimming LEDs in 256 discrete steps for Red/Green/Blue (RGB) color mixing and backlight applications.\nThe PCA9532 contains an internal oscillator with two user programmable blink rates and duty cycles coupled to the output PWM. The • 16 LED drivers (on, off, flashing at a programmable rate)\n• Two selectable, fully programmable blink rates (frequency and duty cycle) between 0.591 Hz and 152 Hz (1.69 second and 6.58 milliseconds)\n• 256 brightness steps\n• Input/outputs not used as LED drivers can be used as regular GPIOs\n• In;
