Overview
The PCA9665D,118 is a parallel-bus to I²C-bus controller IC designed by NXP USA Inc. This component serves as an interface between standard parallel-bus microcontrollers/microprocessors and the serial I²C-bus, enabling communication between these two different bus types. It is particularly useful in systems where a microcontroller or microprocessor needs to interact with I²C-bus devices but does not have a built-in I²C interface.
