PCA9535PW,118 Typical application Circuitry

PCA9535PW,118

The PCA9535PW,118 is a 16-bit I2C-bus and SMBus I/O expander. It is designed to provide additional input/output (I/O) ports to a microcontroller or processor, particularly in systems where the number of available GPIO pins is limited. This chip expands the I/O capabilities using the I2C bus for communication.

PCA9535PW,118 Application Scenarios:

1. I/O Expansion in Embedded Systems: Ideal for embedded systems, such as home automation, industrial controls, or Internet of Things (IoT) devices, where more GPIOs are needed for interfacing with sensors, LEDs, or other peripherals.

2. Control Functions in Consumer Electronics: Used in consumer electronics like smartphones, tablets, and PCs for managing various control functions.

PCA9535PW,118 Key Features and Parameters:

1. 16-Bit I/O Ports: The PCA9535PW,118 provides sixteen additional I/O ports, configurable as inputs or outputs.

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 applications.

4. Programmable Polarity Inversion: Includes the option for programmable polarity inversion on 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: Implementing PCA9535PW,118 to increase the number of GPIOs available for a microcontroller in an IoT device.

1. Power Supply Integration: VDD (pin 24) should be connected to the microcontroller's power supply, typically within the 2.3V to 5.5V range.

2. System Ground Connection: GND (pin 12) needs to be connected to the system's ground.

3. I2C Bus Connectivity: SDA (pin 23) and SCL (pin 22) should be linked to the I2C data and clock lines of the microcontroller.

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, configurable as input or output based on the specific requirements of the IoT application.

5. I2C Address Configuration: 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 VCC or GND as per the desired address scheme.

Design Considerations:

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

2. I2C Addressing Configuration: Correctly set A0, A1, and A2 to prevent address conflicts on the I2C bus.

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

4. I/O Pin Configuration: Appropriately configure P0.0 to P1.7 as inputs or outputs, depending on the IoT device's needs.

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

In summary, the PCA9535PW,118 is a highly effective solution for expanding the GPIO capabilities of microcontroller systems, particularly 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 for various applications where additional GPIOs are essential.
