I2C Hub 1 to 6 Expansion Unit (PCA9548APW)


PaHUB2 unit is an I2C Expandable Hub specifically designed to overcome the limitation of a single I2C interface. It enables the expansion of a single I2C HY2.0-4P interface to accommodate up to 6 additional I2C channels.By employing polling control on the different channels, the hub allows for the connection of multiple slave devices sharing the same I2C address. This facilitates in-device coexistence, as communication with these devices can be achieved without conflicts by switching between the channels.To enhance its functionality, PaHUB2 unit incorporates the PCA9548AP I2C multi-channel switch IC, which is integrated within the hub. This switch IC provides the necessary capabilities for seamless switching between the various I2C channels. With the PaHUB2, concerns regarding the insufficiency of I2C interfaces for expansion are alleviated. It presents a convenient and efficient solution for augmenting the I2C capabilities of your system, enabling the connection and communication with multiple I2C devices that share the same address.
