Avant Electronics SBN1661G_M02
the SBN1661G_M02, • the SBN0080G_S18, and • the SBN0080G_S02. Both the SBN1661G_M18 and the SBN1661G_M02 can drive 16 COMMONs and 61 SEGMENTs and can be used as master in a master-slave connection. They both have 32-row x 80-column Display Data Memory.DESCRIPTION
The SBN1661G_X is a series of STN LCD SEGMENT/COMMON drivers. The series has four members:● the SBN1661G_M18,
● Functionally, their only difference is that the SBN1661G_M18 has an on-chip RC-type oscillator and can provide clock to slave, while the SBN1661G_M02 does not have an on-chip oscillator and needs external clock source. Both the SBN0080G_S18 and the SBN0080G_S02 are purely SEGMENT drivers. They do not have COMMON outputs and are used for segment expansion in a master-slave connection. Both devices need either a master or an external clock source to provide clock. The only difference between these two chips is their operating frequency. The SBN0080G_S18’s operating frequency is 18 KHz, while the SBN0080G_S02’s operating frequency is 2KHz. All four devices have on-chip Display Data Memory of 32-rows x 80-columns, for storing display data. Dot-matrix mapping method is used to drive the LCD panel. Therefore, a bit of the Display Data Memory corresponds to a pixel on the LCD panel.
