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 EEPROM utilizes 2-byte addressing to support the 28-Kb...
