PCF8576CT/1,112 Typical application Circuitry

PCF8576CT 1,112

The PCF8576CT/1,112 is a versatile, low-power LCD driver, primarily designed for driving large multiplexed Liquid Crystal Displays (LCDs). This chip is part of the PCF8576 family, well-known for its ability to drive LCDs with a high number of segments, making it ideal for applications requiring clear and complex visual displays.

Features of PCF8576CT/1,112

1. Driving Capability: The PCF8576CT/1,112 can drive up to 160 LCD segments, offering flexibility for large and complex display designs.

2. Multiplexing Ratio: Supports multiplex rates from static up to 1:40 multiplexing, allowing for versatile display options.

3. Interface: Equipped with an I²C-bus interface, facilitating easy integration with most microcontrollers and processors.

4. Voltage Range: Operates across a wide voltage range, accommodating various power supply requirements.

Application Scenario: Digital Clock Display

In a digital clock application, the PCF8576CT/1,112 can be employed to drive the segment LCD, displaying time in hours, minutes, and seconds. Below are the detailed connections for this application:

Circuit Connection Details

1. Power Supply (VDD - Pin 1, VSS - Pin 19):

- Powering the Device: Connect a stable power source to VDD (Pin 1) for the PCF8576CT/1,112. Typically, this is in the range of 2.5V to 6V. Connect VSS (Pin 19) to the ground.

2. LCD Connection (SEG0-SEG39, COM0-COM3):

- Connecting LCD Segments: Connect the segments of the LCD to the SEG (Segment Output Pins) and COM (Common Return Pins) of the PCF8576CT/1,112. The specific pin assignment depends on the LCD's configuration and the required display pattern.

3. I²C Communication (SDA - Pin 15, SCL - Pin 16):

- Data Transmission: Connect SDA (Pin 15) and SCL (Pin 16) to the corresponding I²C data and clock lines on the microcontroller. This enables communication between the PCF8576CT/1,112 and the microcontroller for updating the display.

4. Mode Selection (M - Pin 17):

- Selecting Operation Mode: Connect M (Pin 17) to either VDD or VSS to select between the two available frame frequencies (80Hz or 160Hz). This affects the refresh rate of the LCD.

5. Bias Configuration (BP0, BP1 - Pins 2 and 3):

- Setting LCD Bias: Configure BP0 (Pin 2) and BP1 (Pin 3) to set the bias ratio for the LCD. This is crucial for optimal contrast and visibility of the display.

6. Oscillator (OS - Pin 18):

- Clock Source: Connect a capacitor to the OS (Pin 18) to set the internal oscillator frequency. This frequency is vital for the timing of the LCD driving waveforms.

Design Considerations

When designing a circuit with the PCF8576CT/1,112, consider the following:

1. LCD Compatibility: Ensure the LCD's segment and common pin count matches the driving capability of the PCF8576CT/1,112.

2. I²C Addressing: Address the PCF8576CT/1,112 correctly if multiple devices are on the same I²C bus.

3. Power Supply Stability: Provide a stable and noise-free power supply to prevent display flickering or corruption.

4. PCB Layout: Design the PCB to minimize cross-talk between the high-speed I²C lines and the LCD lines, which are more susceptible to interference.

By understanding the features and pin configurations of the PCF8576CT/1,112, one can effectively integrate this LCD driver into applications like digital clocks, ensuring a clear and reliable display. The versatility and driving capability of the PCF8576CT/1,112 make it an excellent choice for complex LCD applications.
