ST7066
Display Data RAM (DDRAM)
Display data RAM (DDRAM) stores display data represented in 8-bit character codes. Its extended capacity is 80 x 8
bits, or 80 characters. The area in display data RAM (DDRAM) that is not used for display can be used as general
data RAM. See Figure 1 for the relationships between DDRAM addresses and positions on the liquid crystal display.
The DDRAM address (A
DD
) is set in the address counter (AC) as hexadecimal.

1-line display (N = 0) (Figure 2)
When there are fewer than 80 display characters, the display begins at the head position. For
example, if using only the ST7066, 8 characters are displayed. See Figure 3.
When the display shift operation is performed, the DDRAM address shifts. See Figure 3.
