Mikroe EXPAND 6 Click

Mikroe EXPAND 6 Click uses an I2C configurable multi-port I/O expander with independently configurable pins as bi-directional input/outputs or PWM outputs. The board features the Cypress Semiconductor CY8C9520A 20-bit I/O expander with EEPROM and 4 independently configurable 8-bit PWM outputs. The CY8C9520A operates as two I2C slave devices. First as a multi-port I/O expander and second as a serial EEPROM with 3 Kbyte address space. It has a user default storage flexible I2C address configuration and a programmable interrupt function.
