4 A SBN6400G AND SBN0064G-BASED DISPLAY SYSTEM
A SBN6400G and SBN0064G-based display system is shown in Fig. 5.
The SBN6400G contains timing generation circuit and 64 COMMON drivers. The timing generation circuit generates
operating clocks and display control signals (frame signal FRM , COMMON scan signal CL, and AC frame signal M), for
itself and the SBN0064G.
The SBN0064G contains 64 SEGMENT drivers, Display Data Memory, and interface circuit with a host microcontroller.
