1. Terminal A - Connects to one end of the potentiometer resistor.
2. Terminal B - Connects to the other end of the potentiometer resistor.
3. Terminal W - Connects to the wiper terminal of the potentiometer.
4. VCC - Supply voltage input.
5. U/D - Up/Down control input.
6. CS - Chip select input.
7. GND - Ground reference.
8. NC - No connection.

Functional Features

• Non-volatile storage of wiper position allows for retaining settings even when power is removed.
• 100 tap points provide fine-grained control over resistance.
• Up/Down control interface simplifies integration with microcontrollers and digital systems.
• Low power consumption.
• Small package size enables space-constrained designs.

Advantages and Disadvantages

Advantages: - Non-volatile storage ensures settings are retained. - Fine-grained control over resistance. - Easy integration with digital systems. - Low power consumption.

Disadvantages: - Limited resistance range (10kΩ). - End-to-end resistance tolerance of ±20% may impact precision applications.

Working Principles

The X9C104SZT1 utilizes a series of resistive elements connected in a ladder configuration. The wiper terminal, controlled by the up/down interface, taps into this ladder at different points, effectively changing the resistance between terminals A and B. The non-volatile storage feature allows the device to remember the wiper position even when power is removed.

Detailed Application Field Plans

The X9C104SZT1 can be used in various applications, including:

1. Audio Equipment: Volume control, tone adjustment.
2. Display Systems: Brightness control, contrast adjustment.
3. Industrial Automation: Calibration, fine-tuning of control parameters.
4. Test and Measurement Instruments: Potentiometer simulation, resistance adjustment.
