This Application Note demonstrates the basic features of the Cypress I/O Port Expander family of devices, CY8C95xx. The application examples are described with step-by-step explanation of the configuration process. Attention focuses on both the expander I2C-logic interface characteristics and IC details. The information in this note, along with the CY8C95xx Data Sheet, will simplify system design of I2C slave devices based on the Cypress I/O Expander.
