Overview
PCAL9555A Low-voltage 16-bit I2C-bus GPIO with Agile I/O, interrupt and weak pull-up Rev.
2 — 19 December 2014 Product data sheet 1.
General description The PCAL9555A is a low-voltage 16-bit General Purpose Input/Output (GPIO) expander with interrupt and weak pull-up resistors for I2C-bus/SMBus applications.
NXP I/O expanders provide a simple solution when additional I/Os are needed while keeping interconnections to a minimum, for example, in ACPI power switches, sensors, push buttons, LEDs, fan control, etc.
In addition to providing a flexible set of GPIOs, the wide VDD range of 1.
65 V to 5.
5 V allows the PCAL9555A to interface with next-generation microprocessors and microcontrollers w...
