Description

The PCA9673PW is a 16-channel I2C I/O port expander from NXP Semiconductors. It allows for the expansion of GPIO pins on microcontrollers, enabling more devices to be connected to a single I2C bus. The PCA9673PW is particularly useful in applications where GPIO resources are limited, such as in embedded systems, sensor interfaces, or LED control.
Key features include:
- 16 GPIO pins: Configurable as inputs or outputs.
- I2C interface: Supports standard and fast modes, allowing multiple devices on the same bus.
- Interrupt capability: Supports interrupt generation for changes in input states, enhancing responsiveness.
- Programmable pull-up resistors: Offers flexibility in input configurations.
- Low power consumption: Suitable for battery-operated devices.
The PCA9673PW operates within a wide voltage range (1.65V to 5.5V), making it compatible with various systems. Its small package footprint and ease of integration make it a popular choice for developers seeking to enhance I/O capabilities efficiently.

Features

The PCA9673PW is a 16-bit I2C-bus I/O port expander from NXP Semiconductors. Key features include:
1. 16 GPIO Pins: Configurable as input or output, allowing for versatile interfacing with various devices.
2. I2C Interface: Operates on a standard I2C-bus, supporting multiple devices on the same bus with addresses from 0x20 to 0x27.
