PCA9535PW,112 Typical application Circuitry

PCA9535PW,112

The PCA9535PW,112 is a 16-bit I2C-bus and SMBus low-power I/O expander. This chip is designed to provide additional input/output (I/O) capability to a microcontroller or processor, especially in systems with limited GPIO pins. It uses the I2C bus for communication, making it ideal for expanding the I/O capabilities in various applications.

PCA9535PW,112 Application Scenarios:

1. I/O Expansion in Embedded Systems: Commonly used in embedded systems, like in home automation, industrial controls, or IoT devices, where more GPIOs are required for interfacing with additional sensors, LEDs, or other peripherals.

2. Control Functions in Consumer Electronics: Employed in consumer electronics such as smartphones and PCs for managing various control functionalities.

PCA9535PW,112 Key Features and Parameters:

1. 16-Bit I/O Ports: The PCA9535PW,112 provides sixteen additional I/O ports, each configurable as input or output.

2. I2C-Bus Interface: Compatible with the I2C-bus and SMBus, ensuring easy integration into most microcontroller-based systems.

3. Low Power Consumption: Designed for energy efficiency, making it suitable for battery-powered devices.

4. Programmable Polarity Inversion: Includes programmable polarity inversion for the input ports.

5. Wide Voltage Range: Operates within a voltage range of 2.3V to 5.5V, accommodating various logic levels.

Circuit Connection Example: Expanding GPIOs in an IoT Device

Overview: Using PCA9535PW,112 to enhance the number of GPIOs available to a microcontroller in an Internet of Things (IoT) device.

1. Power Supply Connection:

- VDD (pin 24) should be connected to the microcontroller's power supply, typically within the 2.3V to 5.5V range.

2. Ground Connection:

- The system's ground must be connected to GND (pin 12).

3. I2C Bus Integration:

- The microcontroller's I2C data and clock lines should be linked to pins 23 and 22, respectively, for SDA and SCL.

4. Configuring I/O Ports:

- P0.0 to P0.7 (pins 1-7) and P1.0 to P1.7 (pins 13-20) serve as the I/O ports, which can be programmed as inputs or outputs as needed.

5. I2C Address Setting:

- A0, A1, and A2 (pins 21, 20, and 19, respectively) must be set to define the I2C address of the device, by connecting them to either VCC or GND.

Design Considerations:

1. Voltage Level Compatibility: Ensure that VDD is compatible with the logic level voltage of the microcontroller.

2. I2C Address Configuration: Appropriately set A0, A1, and A2 to avoid conflicts on the I2C bus.

3. Pull-Up Resistors on I2C Lines: Incorporate suitable pull-up resistors on SDA and SCL for stable I2C communication.

4. Input/Output Port Configuration: Properly set up P0.0 to P1.7 as inputs or outputs depending on the specific requirements of the IoT device.

5. Power Consumption Management: Be aware of the low power consumption feature, especially in battery-powered applications.

In summary, the PCA9535PW,112 is an effective solution for expanding the GPIO capabilities of microcontroller systems, particularly beneficial in IoT applications and complex electronics. Its 16-bit I/O expansion, compatibility with I2C-bus standards, and energy-efficient design make it a valuable component in various applications where additional GPIOs are essential.
