This document provides application notes and technical characteristics of the DD-6448BE-2A OLED display module from DENSITRON TECHNOLOGIES plc.
The document describes the EVK board schematic and the pin assignments for the DD-6448BE-2A OLED display module, including power pins (VCC, VDD, VDDIO), control pins (CS, RES, D/C, R/W, E/RD) and data pins (DO~D7, IREF, VCOMH). Detailed symbol definitions and timing parameters for 6800, 8080, and SPI interfaces are provided.
Example C functions for writing commands and data to the display are included, along with recommended initial code for 8080‑series CPUs. The note also references how to use the SSD1305Z driver with the module.
| VCC | Power supply for panel driving voltage |
|---|---|
| VSS | Ground pin |
| VDD | Power supply for core logic operation |
| VDDIO | Power supply for interface logic level |
| Clock Cycle Time (6800 interface) | 300 ns |
| Chip Select Low Pulse Width (read) | 120 ns |
| Chip Select Low Pulse Width (write) | 60 ns |
In serial mode DO becomes the serial clock (SCLK) and D1 becomes the serial data input (SDIN); D2 is left open and D1/D2 are tied together for I2C mode.
