Revision A2
LCD Controller/Driver
The W741E260 can directly drive an LCD with 32 segment output pins and 4 common output pins for a
total of 32
×
4 dots. Option codes can be used to select one of five options for the LCD driving mode:
static, 1/2 Bias 1/2 duty, 1/2 Bias 1/3 duty, 1/3 Bias 1/3 duty, or 1/3 Bias 1/4 duty (see Figure 13). The
alternating frequency of the LCD can be set as Fw/64, Fw/128, Fw/256, or Fw/512. In addition, option
codes can also be used to set up four of the LCD driver output pins (segment 0 to segment 31) as a
DC output port. The structure of the LCD alternating frequency (F
LCD
) is shown in Figure 12.
