The PCA9665PW,118 is a robust I²C-bus controller device designed by NXP Semiconductors to provide an efficient interface between a standard I²C-bus of a microcontroller and the serial I²C-bus. This allows for a seamless communication bridge that enhances the capabilities of microcontrollers with limited I²C-bus connectivity.

Key Features

• Multi-master Capability: The PCA9665PW,118 supports multi-master systems, ensuring that multiple masters can try to take control of the bus without corrupting the data transmission.
• High-speed Interface: It supports fast-mode plus (Fm+) with speeds up to 1 Mbit/s and offers a maximum bus loading of 30 mA on the SDA and SCL pins.
• Operating Voltage Range: This device operates across a wide supply voltage range from 2.3 V to 5.5 V, making it suitable for various applications and logic levels.
• Enhanced Noise Filtering: Includes both a noise filter on the SDA/SCL inputs and a 25 ns glitch filter on the SDA/SCL inputs to suppress noise on the I²C-bus lines.
• Programmable Clock Frequency: The internal oscillator of the PCA9665PW,118 allows for a user-programmable clock frequency, providing flexibility in system design.
