83948AYI-147LFT Typical application Circuitry

83948AYI-147LFT

The 83948AYI-147LFT is a 3.3V, 10-bit, 4-wire resistive touch screen controller with an I²C interface. It is designed for use in applications requiring touch screen input, such as smartphones, tablets, and industrial control panels.

Application Scenario: Touch Screen Interface for a Medical Device

In this scenario, the 83948AYI-147LFT is used to interface a resistive touch screen with a medical device, enabling touch-based input for controlling and navigating through the device's user interface.

1. Power Supply Connections

- VDD: Connect to a stable 3.3V power supply to power the 83948AYI-147LFT (Pin 1).

- GND: Connect to the system ground for a stable reference (Pin 2).

2. Touch Screen Connections

- Y+, Y-: Connect to the Y-axis electrodes of the resistive touch screen (Pins 3 and 4).

- X+, X-: Connect to the X-axis electrodes of the resistive touch screen (Pins 5 and 6).

3. I²C Interface

- SCL: Connect to the I²C clock line of the medical device's microcontroller (Pin 7).

- SDA: Connect to the I²C data line of the medical device's microcontroller (Pin 8).

4. Interrupt Output

- INT: Connect to an interrupt input of the medical device's microcontroller to signal touch events (Pin 9).

Design Considerations:

- Power Supply Stability: Ensure a stable and clean power supply to maintain the performance of the 83948AYI-147LFT.

- Touch Screen Calibration: Calibrate the touch screen to ensure accurate touch detection and coordinate mapping.

- I²C Communication: Implement proper I²C communication protocols in the medical device's firmware to read touch coordinates from the 83948AYI-147LFT.

- Interrupt Handling: Configure the microcontroller to respond to touch interrupts generated by the 83948AYI-147LFT for timely touch event processing.

- EMI/EMC Considerations: Minimize electromagnetic interference to ensure reliable touch screen operation in a medical environment.

In conclusion, the 83948AYI-147LFT is a versatile touch screen controller suitable for use in medical devices, enabling touch-based input for controlling and navigating through the device's user interface. When designing circuits with this chip, it's important to consider power supply stability, touch screen calibration, I²C communication, interrupt handling, and EMI/EMC considerations to ensure reliable and accurate touch screen operation.
