Description

The PCA9532PW is an I²C-bus I/O port expander with interrupt capabilities, manufactured by NXP Semiconductors. It provides a simple way to add GPIO pins to a microcontroller or microprocessor, enabling more devices to be interfaced using fewer I/O pins. The PCA9532PW features 16 GPIO pins that can be configured as inputs or outputs, along with two interrupt outputs to signal the host when an input pin changes state.
Key features include:
- Operating voltage range: 1.8V to 5.5V
- 16-bit I/O port with configurable direction
- Supports I²C communication (up to 1 MHz)
- Built-in interrupt capability for efficient monitoring
- Low-power consumption modes
The device is ideal for applications such as sensor interfacing, LED control, and general-purpose I/O expansion in embedded systems. Its small package size and I²C interface make it suitable for compact designs in consumer electronics, automotive, and industrial applications.

Features

The PCA9532PW is a 16-bit I2C I/O port expander designed to add additional GPIO (General Purpose Input/Output) pins to microcontrollers and other devices. Key features include:
1. 16 GPIO Pins: Configurable as input or output.
2. I2C Interface: Supports standard I2C communication, allowing multiple devices on the same bus.
3. Interrupt Capabilities: Provides interrupt functionality for input state changes, enabling efficient monitoring.
4. Configurable Pull-up Resistors: Integrated pull-up resistors for input pins, enhancing flexibility in circuit design.
5. Multiple Address Options: Supports up to 8 devices on the same I2C bus by allowing different I2C addresses.
6. Low Power Consumption: Designed for low power applications, making it suitable for battery-operated devices.
7. Wide Voltage Range: Operates over a broad supply voltage range (1.8V to 5.5V), compatible with various systems.
Overall, the PCA9532PW is ideal for applications requiring additional I/O capabilities in compact and efficient designs.

Package

The PCA9532PW is available in a TSSOP (Thin Shrink Small Outline Package) 16-pin package type.

Pinout

The PCA9532PW is a 16-pin I²C I/O port expander. It features an 8-bit I/O port that can be configured individually as input or output. Here’s a brief overview of its pin functions:
1. VREF (Pin 1): Reference voltage for the I/O pins.
2. VCC (Pin 2): Positive supply voltage.
3. GND (Pin 3): Ground reference.
4. SDA (Pin 4): Serial Data Line for I²C communication.
5. SCL (Pin 5): Serial Clock Line for I²C communication.
6. INT (Pin 6): Interrupt output for indicating changes in input states.
7. GPIO0 to GPIO7 (Pins 7-14): Configurable general-purpose I/O pins.
8. RESET (Pin 15): Active-low reset pin.
9. NC (Pin 16): No connection.
The PCA9532PW supports remote I/O capabilities, enabling microcontrollers to expand I/O functionality over the I²C bus.
