概要

Description

The PCA9552PW is a dual I²C-bus I/O port expander from NXP Semiconductors. It features 16 GPIO pins, which can be configured either as input or output, enabling the expansion of I/O capabilities for microcontrollers with limited pins. The device operates over a voltage range of 1.8V to 5.5V, making it suitable for a variety of applications, including consumer electronics, automotive, and industrial systems.
The PCA9552PW communicates via the I²C (Inter-Integrated Circuit) bus, allowing multiple devices to be connected on the same bus with unique addresses. It supports interrupt functionality, which can alert the host controller of changes in input states, thus enhancing efficiency.
The device also features programmable pull-up resistors and supports multiple modes of operation, including standard and fast-mode I²C. With its small package size, typically offered in a TSSOP or VQFN form factor, the PCA9552PW is ideal for space-constrained applications requiring additional GPIO.

Features

The PCA9552PW is an I2C-bus I/O port expander designed to increase the number of GPIO pins available for microcontrollers. Key features include:
1. 16 GPIO Pins: Provides 16 additional input/output pins, configurable as input or output.
2. I2C Interface: Operates over the I2C protocol, allowing easy integration with various microcontrollers.
3. 2 Address Pins: Supports multiple devices on the same I2C bus with adjustable addresses.
4. Interrupt Functionality: Features an interrupt output pin that signals changes in the state of input pins, improving responsiveness.
5. Pull-up Resistors: Built-in pull-up resistors for inputs enhance signal integrity.
6. Wide Voltage Range: Compatible with a supply voltage of 1.8V to 5.5V, making it versatile for different applications.
7. Low Power Consumption: Designed for low power usage, suitable for battery-operated devices.
The PCA9552PW is ideal for applications needing additional I/O connections, such as remote sensors, control systems, and user interfaces.

Package

The PCA9552PW is packaged in a TSSOP (Thin Shrink Small Outline Package) with 24 pins.

Pinout

The PCA9552PW is an I²C-bus I/O port with interrupt capabilities, featuring a total of 16 pins. The pin configuration includes:
1. VCC (Pin 1): Supply voltage (2.3V to 5.5V).
2. GND (Pin 2): Ground.
3. SDA (Pin 3): I²C serial data line.
4. SCL (Pin 4): I²C serial clock line.
5. INT (Pin 5): Interrupt output for external signaling.
6. GPIO0 - GPIO7 (Pins 6-13): General-purpose I/O pins, configurable as inputs or outputs.
7. Reset (Pin 14): Active low reset pin.
8. NC (Pins 15-16): No connect (unused pins).
The PCA9552PW allows for configuring each GPIO pin individually, enabling various input/output functionalities, and supports interrupt generation for pin state changes. It is widely used in applications requiring additional I/O expansion controlled via an I²C interface.
