Nexperia introduced a new portfolio of 16-channel I2C general-purpose input-output (GPIO) expanders designed to increase flexibility and reuse in electronic systems. The portfolio provides a solution when additional I/Os are needed while keeping the interconnections to a minimum. Enabling design engineers to add new features without increasing PCB design complexity and bill of material. It includes the NCA9595, the industry’s first GPIO expander to feature a register configurable internal pull-up resistor to enable customized power optimization.
Nexperia’s I2C GPIO portfolio also includes the NCA9535, NCA9539, NCA9555 and NCA9595 devices. These parts have been designed in pin-to-pin compatible packages with industry-standard footprints (TSSOP24 and HWQFN24) to offer a cost-effective and flexible solution for expanding the number of parallel IOs in an electronic system.
