NXP PCA9564D Parallel Bus to I2C-Bus Interface

The PCA9564D is a versatile and robust integrated circuit designed by NXP Semiconductors, aimed at providing a seamless interface between a parallel bus system and an I2C-bus. This interface IC is ideal for applications where an I2C-bus needs to be driven by a microcontroller or processor with a parallel bus interface.

The PCA9564D operates as a master or slave transceiver for the I2C-bus, capable of interfacing with I2C-bus speeds of up to 400 kHz. It features an 8-bit parallel bidirectional data port, an on-chip oscillator with a software programmable clock, allowing for flexibility in controlling I2C-bus timing to accommodate various system requirements.

This product is particularly well-suited for applications that require the conversion of legacy parallel bus designs to modern I2C-bus communication, without the need for significant redesign. It is also beneficial for systems that need to offload the I2C-bus communication tasks from the main processor to maintain optimal performance.

Key Features:

• Multi-master capability, allowing multiple devices to be connected to the bus without communication conflicts.
• Low standby current, contributing to power-efficient designs.
• 5V tolerant I/Os, providing compatibility with legacy devices that operate at higher voltages.
• Interrupt output that can be configured to reflect various status conditions, enabling efficient communication management.
• Active LOW reset input that allows for easy integration into system reset schemes.
• 400 kHz I2C-bus capability.

The PCA9564D comes in a compact SO16 package, making it suitable for space-constrained applications. Its operational temperature range from -40°C to +85°C ensures reliable performance across various environmental conditions. Whether it's for industrial control systems, automotive applications, or consumer electronics, the PCA9564D provides a reliable and efficient solution for parallel to I2C-bus communication.

With its combination of features, the PCA9564D by NXP stands out as an excellent choice for designers looking to implement or upgrade their systems with I2C-bus capabilities.
