NCA9555 GPIO expander evaluation board
NEVB – NCA9555, the NCA95xx evaluation board, is an Arduino™ compatible shield form factor PCB
designed for the Nexperia I²C controlled GPIO expander family. The board provides convenient test points for GND, I²C-Bus signals SCL and SDA as well as an interrupt open drain output. The EVB can be used for the GPIO expander derivatives NCA9555, NCA9535, NCA9539 and NCA9595.
Key features & benefits
- Input voltage = 1.6 V to 5.5 V
- I²C to parallel port expansion
- Number of GPIOs = 2 ports with 8 bits
- Current drive capability = ± 25 mA
- I²C interface, Fast-Mode 400 kHz
- Open-drain active-low interrupt output
- Configurable slave address via 3 selection pins (2 pins for NCA9539)
- Low-active reset input (NCA9539)
