Description and Introduction

Parallel bus to I2C-bus controller The **PCA9564D** from Philips is a versatile **I²C-bus controller** designed to facilitate communication between microcontrollers and I²C-bus compatible devices. This integrated circuit (IC) serves as a bridge, enabling seamless data transfer in applications requiring efficient serial communication.  

Featuring a **parallel bus interface**, the PCA9564D simplifies integration with host processors, making it ideal for embedded systems, industrial automation, and consumer electronics. Its **bidirectional data transfer capability** ensures reliable communication, while built-in error detection enhances system robustness.  

Key specifications include **low power consumption**, making it suitable for battery-operated devices, and **wide operating voltage ranges** for compatibility with various logic levels. The IC supports **standard and fast I²C modes**, accommodating different speed requirements.  

Engineers value the PCA9564D for its **compact footprint** and ease of implementation, reducing development time in complex designs. Whether used in sensor networks, display controllers, or peripheral interfacing, this component delivers consistent performance in demanding environments.  

With Philips' reputation for quality, the PCA9564D remains a trusted solution for designers seeking a reliable I²C-bus controller with advanced functionality. Its balance of efficiency, flexibility, and durability makes it a preferred choice in modern electronic systems.

Application Scenarios & Design Considerations

Parallel bus to I2C-bus controller

Alternative Part Number

  • TCA9548APWR --: I2C bus switch/multiplexer from TI that can serve similar I2C bus expansion and control roles in many designs, widely available and well documented.
  • PCF8574T --: NXP I2C I/O expander in the same I2C peripheral family, useful as a functional substitute when the parallel bus controller function is not strictly required.
  • MCP23017-E/SS --: Popular I2C I/O expander with broad availability and strong documentation, suitable as a functional alternative for I2C-based peripheral control.
  • PCA9564PW --: Same PCA9564 parallel bus to I2C controller family from the original chip designer, TSSOP package instead of SO, fully function-compatible.
  • PCA9564BS --: Same controller function in a smaller HVQFN package, suitable when board space is tight and layout can be adapted.
  • TDA8024T --: Related I2C-bus interface/controller IC from a different series that can serve similar bus-bridging roles in some designs, though pinout and features should be verified.
  • PCF8584T --: I2C bus controller from NXP with a parallel interface, offering similar bus-controller functionality and often used as a replacement when the PCA9564 is unavailable.
  • ST24C04 --: Alternative I2C interface device from a different vendor and series, suitable for designs needing an I2C-compatible controller when the original Philips part is not obtainable.
