PCF8574T/3,518 Typical application Circuitry

PCF8574T 3,518

The PCF8574T/3,518 is an integrated circuit (IC) primarily designed as an I2C-bus controlled 8-bit I/O expander. Its main function is to increase the number of I/O ports available to a microcontroller or processor using the I2C-bus, which is particularly useful in applications with limited GPIO (General Purpose Input/Output) availability. This overview will detail the functionality of the PCF8574T/3,518, its application scenarios, parameter features, and a specific circuit connection guide.

Functionality: The PCF8574T/3,518 serves as an I/O expander, providing additional I/O ports through the I2C-bus, enabling enhanced control and interaction with a range of external devices.

Application Scenarios: The PCF8574T/3,518 is widely used in embedded systems and microcontroller-based projects, such as in home automation, robotics, and sensor networks, where additional I/O ports are necessary.

Parameter Features:

1. I/O Ports Expansion: Offers eight additional I/O ports for microcontroller systems.

2. I2C-Bus Interface: Employs the I2C communication protocol for efficient integration and data transfer.

3. Low Power Consumption: It is optimized for minimal power usage, suitable for battery-powered applications.

4. Voltage Range Compatibility: Operates across a range of voltages, accommodating different microcontroller logic levels.

Circuit Connection - Home Automation System:

1. Power Supply Linkage: Connect the VCC pin (e.g., pin 16) of the PCF8574T/3,518 to a stable power source.

2. Grounding the IC: Attach the GND pin (e.g., pin 8) to the system's ground.

3. I2C Bus Configuration: Interface the SDA (Serial Data, pin 15) and SCL (Serial Clock, pin 14) pins of the PCF8574T/3,518 with the microcontroller's I2C bus.

4. External Device Connection: Link the I/O pins (e.g., P0 to P7, pins 1-7, 9-12) of the PCF8574T/3,518 to various components like switches, sensors, or actuators in the home automation system.

Design Considerations:

- Stable Power Source: Ensure a consistent power supply for the reliable operation of the PCF8574T/3,518.

- I2C Bus Management: Proper configuration of the I2C bus, including addressing and pull-up resistors, is crucial for communication.

- Address Pin Settings: Correctly set the address pins (A0, A1, A2) to prevent conflicts on the I2C bus.

In summary, the PCF8574T/3,518 is integral in expanding the I/O capabilities of microcontroller systems, particularly useful in home automation projects. Designing circuits for the PCF8574T/3,518 involves careful consideration of power supply, I2C bus configuration, and address pin settings.
