NXP PCA9564BS Parallel Bus to I2C-Bus Protocol Interface

The NXP PCA9564BS is a highly versatile interface chip designed to provide a seamless bridge between a parallel bus system and an I2C-bus. This allows a microcontroller or processor that is not equipped with an I2C-bus interface to communicate with I2C-bus compatible devices. The PCA9564BS is ideal for enhancing the connectivity of microcontrollers and is well-suited for a variety of applications in the automotive, industrial, and consumer electronics sectors.

At the heart of the PCA9564BS is its ability to act as a master or slave interface for the I2C-bus and a parallel-bus master. It supports both the Standard-mode and Fast-mode I2C-bus protocols as per the I2C-bus specification, providing data transfer rates of up to 100 kbit/s and 400 kbit/s, respectively. The PCA9564BS is designed with an 8-bit parallel bus interface, which includes an interrupt line (INT) to alert the host controller of changes in the I2C-bus status.

One of the key features of the PCA9564BS is its built-in programmable timer, which allows for a watchdog function and a timeout function on the SCL (Serial Clock Line) and SDA (Serial Data Line). This ensures a high level of data integrity and reliability in communication. Additionally, the device has an operating voltage range from 2.5V to 5.5V, making it flexible for use in various system designs.

The PCA9564BS comes in a compact SO16 package, which is space-efficient and suitable for applications where board space is at a premium. It also has a low stand-by current, making it energy-efficient and ideal for battery-powered applications. The device's address recognition capability supports up to eight different hardware addresses, allowing multiple devices to share the same parallel bus and I2C-bus.

In summary, the NXP PCA9564BS is a powerful protocol interface chip that offers a convenient and efficient solution for systems that require parallel bus to I2C-bus communication. Its compatibility with multiple I2C-bus modes, programmable timer, and low power consumption make it an excellent choice for a wide range of applications.
