GENERAL
Description
The SBN1661G_X is a series of STN LCD SEGMENT/COMMON drivers. The series has four members:
•
the SBN1661G_M18,
•
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. 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. SEGMENT drivers provide display data to the LCD panel and COMMON drivers provide row-scanning signal.
All four devices have a set of internal registers. These internal registers must be properly programmed to ensure proper
operation of the devices.
Display on the LCD panel is controlled by a host microcontroller. All four devices communicate with the host
microcontroller via data bus and control bus. The data bus is 8-bit wide. The control bus are READ, WRITE, and
Chip Select. The host microcontroller can perform READ/WRITE operations to the internal registers and Display Data
RAM of all four devices. A wide variety of microcontrollers can easily interface with the devices, as the devices can accept
both 80-type interface timing and 68-type interface timing. The selection of interface timing is via the dual-function
RESET/IF pin.
