Description

NXP PCA9556PW 8-bit I²C-bus and SMBus I/O port with interrupt

The NXP PCA9556PW is a highly versatile 8-bit I/O expander chip designed to provide additional I/O capabilities to microcontroller-based systems via the I²C-bus and SMBus serial interfaces. This integrated circuit is particularly useful in applications where I/O pins are limited and additional inputs or outputs are required.

Key Features:

  • Interface: The PCA9556PW is compatible with the I²C-bus and SMBus standards, allowing for seamless integration with a wide range of microcontrollers and processors.
  • Channels: It provides 8 I/O pins that can be individually configured as inputs or outputs, offering flexibility for various application needs.
  • Interrupt Output: An interrupt output is available and can be triggered by input state changes, reducing the need for the microcontroller to continuously poll the I/O expander.
  • Operating Voltage: The device operates within a supply voltage range of 2.3V to 5.5V, making it suitable for both 3.3V and 5V systems.
  • Power Consumption: It features a low standby current, which is advantageous for power-sensitive applications.
  • Packaging: The PCA9556PW comes in a TSSOP16 package, which is ideal for space-constrained applications.

Applications:

The PCA9556PW is ideal for a variety of applications where additional I/Os are necessary. These include:

  • Server motherboards
  • Embedded systems
  • Industrial control systems
  • Robotics
  • Portable electronics

With its ease of use, low power consumption, and interrupt feature, the NXP PCA9556PW is an excellent choice for expanding the I/O capabilities of your next project or product design.
