Description

Product Overview: NXP PCA9549PW I²C Switch

The NXP PCA9549PW is a high-performance, low-voltage 8-channel I²C switch with an interrupt logic, designed to provide flexible I²C-bus connectivity in complex applications. This device is an ideal solution for managing multiple I²C devices or extending I²C-bus communication in a multi-master I²C environment.

Key Features

  • Multiple Channels: The PCA9549PW features 8 bidirectional translating switches that allow connection of up to eight separate I²C-bus slave sub-systems.
  • Channel Selection: Each channel can be independently enabled or disabled via I²C-bus commands, ensuring precise control and flexibility.
  • Voltage Level Translation: The switch supports voltage level translation between 2.3V and 5.5V, making it suitable for applications that require communication between devices operating at different voltage levels.
  • Interrupt Functionality: An interrupt input for each channel allows the PCA9549PW to notify the master when an event occurs on the slave side, improving system responsiveness.
  • Power-Up Configuration: The device powers up with all channels deselected, minimizing the risk of unintended communication after reset.

Applications

The PCA9549PW is versatile and can be used in a variety of applications, including but not limited to:

  • Server management
  • Industrial control systems
  • Advanced TCA (ATCA) systems
  • Medical equipment
  • Multi-master I²C environments

Technical Specifications

  • Package: TSSOP24
  • Supply Voltage: 2.3V to 5.5V
  • Operating Temperature: -40°C to 85°C
  • Compliance: Compliant with I²C-bus Fast and Standard mode

The NXP PCA9549PW is designed to address the needs of complex systems that require robust I²C-bus communication. Its ability to manage multiple I²C devices, along with its interrupt capabilities and voltage level translation, makes it an essential component for designers looking to enhance their system's performance and reliability.
