PCF8523T/1,118 Typical application Circuitry

PCF8523T 1,118

The PCF8523T/1,118 is a low-power consumption real-time clock (RTC) and calendar chip that offers complete binary-coded decimal (BCD) clock and calendar functionality. It's typically used in applications where accurate timekeeping is crucial.

Features of PCF8523T/1,118

1. Clock and Calendar: The PCF8523T/1,118 maintains seconds, minutes, hours, days, weekdays, months, and years with leap year compensation.

2. Alarm Function: It provides alarm capabilities allowing the user to set a daily or a single alarm.

3. Timing Precision: It includes a built-in oscillator circuit and is designed for high accuracy and low power consumption.

4. Communication Interface: It has an I²C-bus interface for straightforward integration into various systems.

Application Scenario: Data Logging System

In a data logging system, the PCF8523T/1,118 can be used to provide precise time stamps for each data entry. Here's a detailed guide for connecting this in a data logging system:

Circuit Connection Details

1. Power Supply (VCC - Pin 8, GND - Pin 4):

- Device Powering: Connect a stable power source to VCC (Pin 8) to power the PCF8523T/1,118. Connect GND (Pin 4) to the ground to complete the power circuit.

2. I²C Communication (SDA - Pin 6, SCL - Pin 5):

- Microcontroller Communication: Attach SDA (Pin 6) and SCL (Pin 5) to the corresponding I²C data and clock lines on the microcontroller. This enables communication between the PCF8523T/1,118 and the microcontroller for time data synchronization.

3. Interrupt (INT - Pin 7):

- Alarm and Timer Notification: Connect INT (Pin 7) to an interrupt pin on the microcontroller. This allows the PCF8523T/1,118 to notify the microcontroller when an alarm or a timer event occurs.

4. Backup Battery (Vbat - Pin 3):

- Maintaining Timekeeping: Connect a backup battery to Vbat (Pin 3) to ensure continuous timekeeping in the event of a main power failure.

5. Clock Output (CLKOUT - Pin 1):

- Frequency Output: (Optional) Connect CLKOUT (Pin 1) if a clock signal output is required for other parts of the system.

Design Considerations

When designing a circuit with the PCF8523T/1,118, consider the following:

1. Power Supply Integrity: Ensure that the power supply is stable and clean to maintain accurate timekeeping.

2. Backup Battery: Install a backup battery correctly to ensure continuous operation during power outages.

3. I²C Bus Integrity: Ensure that the I²C bus lines are correctly pulled up and that the bus is not overly loaded to maintain reliable communication.

4. Interrupt Handling: Effectively manage the interrupt signal to ensure that the microcontroller can appropriately respond to alarm or timer events.

By meticulously incorporating these considerations and understanding the functionalities and pin configurations of the PCF8523T/1,118, one can effectively integrate this RTC into sophisticated applications like a data logging system. The PCF8523T/1,118, with its precise timekeeping and alarm features, is an excellent choice for systems where accurate time stamps are critical.
