Overview
The PCA9663B,118 is an advanced single master mode I2C-bus controller produced by NXP USA Inc. This fourth-generation bus controller is designed for data-intensive I2C-bus data transfers, making it an ideal component for systems that require efficient and reliable serial communication. The device features three independent I2C-bus channels, each capable of data rates up to 1 Mbits/s using the Fast-mode Plus (Fm+) open-drain topology. It is particularly suited for applications where large amounts of serial data need to be transmitted and received, thanks to its generous 4352-byte data buffer per channel.
