ST7036

z 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 6 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.

¾ 1-line display (N3=0,N = 0) (Figure 7)

When there are fewer than 80 display characters, the display begins at the head position. For

example, if using only the ST7036, 20 characters are displayed. See Figure 7.

When the display shift operation is performed, the DDRAM address shifts. See Figure 8.
