Extension Driver LSI Interface (HD66730)
The HD66730 can interface with extension drivers using extension driver interface signals CL1, CL2, D,
and M output from the HD66730, increasing the number of display characters (Figure 35). Although the
liquid crystal driver voltage that drives the booster of the HD66730 can also be used as the driver power
supply of extension drivers, the output voltage drop of the booster increases as the load of the booster
increases.
