This application note details the Philips Semiconductors family of bus controllers. PCA9564 device operation, software and hardware methodology and typical applications are discussed.
The document provides an overview of the PCA9564 I2C‑bus controller, including its functional description, features, and typical applications such as master/slave operation and multi‑master environments. It compares the PCA9564 with the older PCF8584 and outlines the differences in voltage range, clock speed, and supported modes.
Detailed sections cover the device pinout for various packages, ordering information, a block diagram, register definitions, and a FAQ. Additional information includes links to datasheets, IBIS models, and contact details for technical support.
