What type of interface does a typical 128x64 COG LCD display use?

A typical 128x64 COG (Chip-on-Glass) LCD display commonly uses a parallel 8-bit or 4-bit MCU (Microcontroller Unit) interface, often referred to as an 8080-series or 6800-series parallel interface. This interface is widely supported by standard microcontrollers and allows direct, high-speed communication for controlling pixels.

Additionally, many modern variants may also support Serial Peripheral Interface (SPI) or I²C to save GPIO pins on the microcontroller. Among these, SPI is particularly popular for its balance of speed and pin efficiency.

Key characteristics of the interface include:

Low Pin Count: COG technology minimizes external connections, often requiring only 10–20 pins for power, control, and data.

Flexibility: It can be configured to match the host MCU’s capabilities (e.g., 4-bit mode for pin-saving, 8-bit for faster updates).

Embedded Controller: The display integrates a driver IC (e.g., ST7567, ST7565, or similar) that handles pixel addressing, reducing the MCU’s computational load.
