NEVB-NCA6416 Low-voltage translating 16-bit I²C-bus / SMBus I/O expander evaluation board
The NEVB-NCA6416 evaluation board is a compact platform for evaluating Nexperia’s 16-bit I²C-bus I/O expander with integrated voltage-level translation, interrupt, and RESET capability. It enables GPIO expansion between mixed-voltage domains using a dual-supply architecture, allowing seamless interfacing between the I²C bus and port pins. The board provides access to all 16 GPIOs, SDA, SCL, INT, and RESET signals, along with jumper-selectable address configuration via a single address pin. Dedicated test points support signal monitoring and debugging, and the board supports Standard-mode and Fast-mode I²C operation.
