HSM0802A – 8×2 Character LCD Display (STN-Y/G Positive) with Parallel Interface

Product Overview

The HSM0802A is an STN-type positive transmissive LCD module designed for displaying 8 characters × 2 lines in a compact form factor.

It adopts STN yellow-green display mode, offering clear visibility under indoor and low-light conditions.

Driven by the AIP31066 controller, it supports standard 8-bit parallel interface and 5V logic operation, making it fully compatible with MCU platforms such as Arduino, and 8051.

Its LED backlight provides stable illumination with 3.2V forward voltage, and the display operates reliably from –20°C to +70°C, suitable for industrial and commercial environments.

Key Features

8×2 Character Display (STN-Y/G) – Clear and energy-efficient character visualization.

Parallel Interface (8-bit) – Compatible with most MCUs and development boards.

AIP31066 Driver IC – Equivalent to HD44780 controller, widely supported.

5V Logic Supply (VDD) – Easy system integration with standard 5V designs.

3.2V LED Backlight (20mA) – Uniform illumination and long lifetime.

Operating Temperature: –20°C ~ +70°C – Reliable for industrial environments.

Compact PCB Size: 58.0 × 32.0 mm – Ideal for space-constrained designs.

Applications

Industrial Control Panels – Parameter display and menu navigation.

Test and Measurement Instruments – Compact readout interface.

Embedded Systems – MCU-based control and monitoring projects.

Home Appliances – Timers, controllers, and digital interfaces.
