Mikroe EXPAND 7 Click has a multi-port I/O expander with bi-directional input/outputs or PWM outputs. The board features the Cypress Semiconductor CY8C9540A 40-bit I/O port expander with EEPROM and 8 independently configurable 8-bit PWM outputs. The CY8C9540A operates as two I2C slave devices, first as a multi-port I/O expander, and second as a serial EEPROM with 11 Kbyte address space. It has a user default storage, flexible I2C address configuration, and a programmable interrupt and reset function.
