I/O Expander, ET64C16Y, ETEK Microelectronics

The ETQ64C16 is a 16-bit general purpose I/O expander that provides remote I/O expansion for most micro-controller families via the I2C-bus interface.ET64C16YAM provides a simple solution for I/O port expansion, which can be realized with little interconnection. In addition to providing a set of flexible GPIO ports, it also supports the level conversion between different voltage devices, so that it can be flexibly applied in multi voltage mixed signal environment. The INT can be connected to the interrupt input of the micro-controller. By sending the interrupt signal, the micro-controller port is informed that there is data entering, instead of passing through I2C BUS.

The Port P output of ET64C16YAM can provide 25mA perfusion current, which can directly drive LED. The hardware address pin (A2、A1、A0) can be used to program and change the I2C BUS address.
