FSTN 7 Segment LCD Display Module Customized PCB Board White Backlight LCD Display

The HT1623 is an LCD driver IC commonly used to control segment-based LCDs. It’s designed for microcontroller-based applications where a low-power, cost-effective LCD solution is needed.

Key Features:

• Driver for Static & Multiplexed LCDs: Supports up to 256 segments.

• Serial Interface: Communicates via a 3-wire SPI-like interface.

• Low Power Consumption: Ideal for battery-powered applications.

• Integrated Bias Voltage Generator: Supports 1/2 or 1/3 bias driving.

• Internal Oscillator: Reduces the need for an external clock.

• Wide Operating Voltage: Typically 2.4V to 5.5V.

• Built-in RAM: Stores display data to reduce microcontroller workload.

Pinout Overview:

• CS (Chip Select) – Enables communication.

• CLK (Clock) – Serial data clock input.

• DATA – Serial data input.

• VDD / VSS – Power supply.
