The Infineon IO Expander is a multi port IO expander with on board user available EEPROM and several PWM outputs. All devices in this family operate identically but differ in IO pins, number of PWMs and internal EEPROM size. The IO expanders data pins can be independently assigned as inputs, outputs, quasi bidirectional input outputs or PWM outputs. The individual data pins can be configured as open drain or collector, strong drive, resistively pulled up or down or high impedance. The factory default configuration is pulled up internally.

User default storage
Internal power on reset
IO port settings in internal EEPROM
Optional EEPROM write disable input
Internal configurable watchdog timer
I2C interface logic electrically compatible with SMBus
