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 (ADD ) 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.

!" 2-line display (N = 1) (Figure 4)
Case 1: When the number of display characters is less than 40 × 2 lines, the two lines are displayed from the head. Note that
the first line end address and the second line start address are not consecutive. For example, when just the ST7066 is
used, 8 characters × 2 lines are displayed. See Figure 5.
