PCAL6416A

Low-voltage translating 16-bit I²C-bus/SMBus I/O expander

with interrupt output, reset, and configuration registers

Rev. 6.2 — 7 April 2017

Product data sheet

1. General description

The PCAL6416A is a 16-bit general-purpose I/O expander that provides remote I/O

expansion for most microcontroller families via the I²C-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 PCAL6416A

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_DDrange 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 PCAL6416A: 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 PCAL6416A is provided through V_DD(I2C-bus)

_DD(I2C-bus)should be connected to the V_DDof the external SCL/SDA lines. This indicates

the V_DDlevel of the I²C-bus to the PCAL6416A, while the voltage level on Port P of the

PCAL6416A is determined by the V_DD(P)

The PCAL6416A contains the PCA6416A register set of four pairs of 8-bit Configuration,

Input, Output, and Polarity Inversion registers and additionally, the PCAL6416A has

Agile I/O, which are additional features specifically designed to enhance the I/O. These

additional features are: programmable output drive strength, latchable inputs,

programmable pull-up/pull-down resistors, maskable interrupt, interrupt status register,

programmable open-drain or push-pull outputs. The PCAL6416A is a pin-to-pin

replacement to the PCA6416A, however, the PCAL6416A powers up with all I/O interrupts

masked. This mask default allows for a board bring-up free of spurious interrupts at

power-up.

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. Programmable pull-up and pull-down resistors eliminate the need for discrete

components.
