I/O Expander, ET6416Y, ETEK Microelectronics

The ET6416Y 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. ET6416Y 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.

ET6416Y has two supply voltage port: VDDI and VDDP, VDDI provides the power supply voltage for the interface of the main control terminal(micro-controller) and VDDP provides the power supply voltage for the core circuit and Port P. ET6416Y has four pairs of 8-bits registers: configuration register, input register, output register and polarity reversal register.
