Product Description

Introduction to GXA535

GXA535 is mainly used for expanding general-purpose input/output (GPIO) ports. Port data is transmitted via the standard two-wire I²C protocol, supporting a maximum communication rate of 1MHz (up to 2MHz when the high-speed mode is enabled).


GXA535 features 16 push-pull GPIO ports, all of which can directly drive LED components. Each bit of the GPIO ports can be independently configured as input or output mode, with the default mode being input upon power-on.
