Product details

Description

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 back light applications.

Features

16 LED drivers (on, off, flashing at a programmable rate).
2 selectable, fully programmable blink rates (frequency and duty cycle) between 0.625 and 160 Hz (6.4 seconds and 6.25 milliseconds).
256 brightness steps.
Input/outputs not used as LED drivers can be used as regular GPIOs.
Internal oscillator requires no external components.
I2C-bus interface logic compatible with SMBus.
Internal power-on reset.
Noise filter on.
