Mikroe Expand 13 Click features the Diodes Incorporated PI4IOE5V96248 48-bit general-purpose I/O expander. The PI4IOE5V96248 provides remote I/O expansion for most MCU families. It comes in a 6-channel configuration and allows easy addition of I/O through a standard I2C serial interface. The device has a built-in level shifting feature that makes it highly flexible in power supply systems where communication between incompatible I/O voltages is required. It also contains a reset and interrupts feature that informs the MCU of incoming data on its ports without communicating via the serial bus.
