HD61830B

HD61830/HD61830B LCDC (LCD Timing Controller) ADE-207-275(Z) '99.9 Rev. 0.0 Description The HD61830/HD61830B is a dot matrix liquid crystal graphic display controller LSI that stores the display data sent from an 8-bit microcontroller in the external RAM to generate dot matrix liquid crystal driving signals. It has a graphic mode in which 1-bit data in the external RAM corresponds to the on/off state of 1 dot on liquid crystal display and a character mode in which characters are displayed by storing character codes in the external RAM and developing them into the dot patterns with the internal character generator ROM. Both modes can be provided for various applications. The HD61830/HD61830B is produced by the CMOS process. Thus, combined with a CMOS microcontroller it can complete a liquid crystal display device with lower power dissipation. Features Dot matrix liquid crystal graphic display controller Display control capacity  Graphic mode: 512k dots (216 bytes)  Character mode: 4096 characters (212 characters) Internal character generator ROM: 7360 bits  160 types of 5 × 7 dot characters  32 types of 5 × 11 dot characters Total 192 characters  Can be extended to 256 characters (4 kbytes max.) with external ROM 1 HD61830/HD61830B Interfaces to 8-bit MPU Display duty cycle (can be selected by a program) Static to 1/128 duty cycle Various instruction functions  Scroll, cursor on/off/blink, character blink, bit manipulation Display method: Selectable A o...
