Product data sheet
1. General description
The PCA6416A is a 16-bit general purpose I/O expander that provides remote I/O
expansion for most microcontroller families via the I
2
C-bus interface.
NXP I/O expanders provide 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. In addition to providing
a flexible set of GPIOs, it simplifies interconnection of a processor running at one voltage
level to I/O devices operating at a different (usually higher) voltage level. The PCA6416A
has built-in level shifting feature that makes these devices extremely flexible in mixed
signal environments where communication between incompatible I/O voltages is required.
Its wide V
DD
range of 1.65 V to 5.5 V on the dual power rail allows seamless
communications with next-generation low voltage microprocessors and microcontrollers
on the interface side (SDA/SCL) and peripherals at a higher voltage on the port side.
There are two supply voltages for PCA6416A: V
DD(I2C-bus)
and V
DD(P)
. V
DD(I2C-bus)
provides the supply voltage for the interface at the master side (for example, a
microcontroller) and the V
DD(P)
provides the supply for core circuits and Port P. The
bidirectional voltage level translation in the PCA6416A is provided through V
DD(I2C-bus)
.
V
DD(I2C-bus)
should be connected to the V
DD
of the external SCL/SDA lines. This indicates
the V
DD
level of the I
2
C-bus to the PCA6416A. The voltage level on Port P of the
PCA6416A is determined by the V
DD(P)
.
The PCA6416A register set consists of four pairs of 8-bit Configuration, Input, Output, and
Polarity Inversion registers.
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 configuration bits. The data for
each input or output is kept in the corresponding input or output register. The polarity of
the Input Port register can be inverted with the Polarity Inversion register, saving external
logic gates.
The system master can reset the PCA6416A in the event of a time-out or other improper
operation by asserting a LOW in the RESET input. The power-on reset puts the registers
in their default state and initializes the I
2
C-bus/SMBus state machine. The RESET pin
causes the same reset/initialization to occur without depowering the part.
The PCA6416A open-drain interrupt (INT) output is activated when any input state differs
from its corresponding Input Port register state and is used to indicate to the system
master that an input state has changed.
