HD66410 (RAM-Provided 128-Channel Driver for Dot-Matrix Graphic LCD) Preliminary Description The HD66410 drives and controls a dot-matrix graphic LCD using a bit-mapped display method. It provides a highly flexible display through its onchip display RAM, in which each bit of data can be used to turn on or off one dot on the LCD panel. A single HD66410 can display a maximum of 128 × 33 dots using its powerful display control functions. It features 24-channel annunciator output operating with 1/3 duty cycle that is available even during standby modes, which makes it suitable for time and other mark indications. An MPU can access the HD66410 at any time because the MPU operations are asynchronous with the HD66410’s system clock and display operations. Its low-voltage operation at 2.2 to 3.6 V and the standby function provides low power-dissipation, making the HD66410 suitable for small portable device applications.
