8080/6800 Interface LCD 320x240 COB Module - RG320240B - Raystar

8080/6800 Interface LCD Module 320x240 COB Graphic Module (RA8835 IC)

Model No. RG320240B

The RG320240B is a 5.67-inch 320×240 COB graphic LCD module with RA8835 IC. Powered by the RA8835 controller IC, it supports both 8080 LCD interface and 6800 LCD communication modes. The 8080 interface offers faster data transmission and higher efficiency, while the 6800 LCD interface features a simple structure and easy control, allowing developers to integrate the display easily into various embedded systems. The module features a 1/240 duty cycle, LED backlight, and an active area of 115.18 × 86.38 mm, ensuring clear and uniform visual performance.

Engineered with a Chip-on-Board (COB) structure for durability and reliability, the RG320240B 8080 LCD operates within a -20°C to +70°C temperature range and runs on a 5V logic supply with a typical current of 100 mA. Its robust design and flexible 8080/6800 interface LCD compatibility make it ideal for industrial control systems, test instruments, and human–machine interface (HMI) devices.
