Overview The CY8C95xx is a multi-port I/O expander with on-board useravailable EEPROM and several PWM outputs. All devices in this family operate identically but differ in I/O pins, number of PWMs, and internal EEPROM size. The CY8C95xx operates as two I2C slave devices. The first device is a multi-port I/O expander (single I2C address to access all ports via registers). The second device is a serial EEPROM. Dedicated configuration registers can be used to disable the EEPROM. The EE.
