Description

The PI4IOESV6416Q is a 16-bit general-purpose I/O expander that provides remote I/O expansion for most microcontroller families via the l2C-bus interface.

It provides a simple solution when additional I/Os are needed while keeping interconnections to a minimum, for example, in battery-powered mobile applications for interfacing to sensors, push buttons, keypad, etc.

It can operate from 1.65 V to 5.5 V on the GPIO-port side and 1.65V to 5.5V on the SDA/SCL side. This allows the PI4IOE5V6416Q to interface with next generation microprocessors and microcontrollers on the SDA/SCL side, where supply levels are dropping down to conserve power.

The bidirectional voltage-level translation in the PI4IOE5V6416Q is provided through VDD (I2C_bus). VDD (I2C_bus) should be connected to the VDD of the external SCL/SDA lines. The voltage level on the GPIO-port of the PI4IOE5V6416Q is determined by VDD(P).

At power on, the I/Os are configured as inputs; however, the system master can enable the I/Os as either inputs or outputs by writing to the I/O direction bits. The data for each input or output is kept in the corresponding Input or Output register. All registers can be read by the system master.

PI4IOESV6416Q has open-drain interrupt (INT) output pin that goes LOW when the input state of a GPIO-port changes from the input-state default register value. The device also has an interrupt masking feature by which the user can mask the interrupt from an individual GPIO port.
