Vue d'ensemble

Description

The PCA9555PW is a 16-bit I²C I/O port expander from NXP Semiconductors. It allows microcontrollers to increase the number of GPIO (General Purpose Input/Output) pins by connecting additional I/O pins via the I²C bus. The device features two 8-bit ports, which can be configured as input or output, making it versatile for various applications.
Key features include:
- I²C interface with a 1.8V to 5.5V supply voltage range.
- Configurable input/output modes for each pin.
- Interrupt capabilities for input state changes.
- Integrated pull-up resistors for convenience.
The PCA9555PW is commonly used in applications where additional I/O is needed, such as LED control, sensor interfacing, or expanding connectivity in embedded systems. It simplifies hardware design by reducing the number of direct microcontroller pin connections. The device is available in a compact package, making it suitable for space-constrained designs.
For further details, refer to the official datasheet from NXP.
