SSD1815B
Advance Information
LCD Segment / Common Driver
with Controller
CMOS
SSD1815B is a single-chip CMOS LCD drivers with controllers for dot-matrix graphic liquid crystal display system.
SSD1815B is capable to drive 132 Segments, 64 Commons and 1 icon line by its 197 high voltage driving output.
SSD1815B display data directly from their internal 132 x 65 bits Graphic Display Data RAM (GDDRAM). Data/Commands
are sent from common MCU through 8-bit Parallel or Serial Interface. The selection of whether 6800- or 8080-series compatible
Parallel Interface or Serial Peripheral Interface is done by hardware pins configuration.
SSD1815B embeds a DC-DC Converter, an On-Chip Bias Divider and an On-Chip Oscillator which reduce the number of
external components. With the advanced design on minimizing power consumption and die/package layout, SSD1815B is suit-
able for any portable battery-driven applications requiring a long operation period with a compact size.

Oscillator Circuit
This module is an On-Chip low power RC oscillator circuitry (Figure 4). The oscillator generates the clock for the DC-DC
voltage converter. This clock is also used in the Display Timing Generator.

LCD Driving Voltage Generator and Regulator
This module generates the LCD voltage required for
display driving output. With reference to VDD, it takes a sin-
gle supply input, VSS, and generate necessary voltage lev-
els. This block consists of:
1. 2X, 3X and 4X DC-DC voltage converter
The built-in DC-DC voltage converter is used to gener-
ate the large negative voltage supply with reference to VDD
from the voltage input (VSS1). SSD1815B is possible to
produce 2X, 3X or 4X boosting from the potential different
between VSS1 - VDD.
Detail configurations of the DC-DC converter for differ-
ent boosting multiples are given in Figure 5.
2. Voltage Regulator (Voltages referenced to VDD)
The feedback gain control for LCD driving contrast
curves can be selected by IRS pin to either internal (IRS pin
= H) or external (IRS pin = L).
If internal resistor network is enabled, eight settings
can be selected through software command.
If external control is selected, external resistors are re-
quired to be connected between VDD and VF (R1), and be-
tween VF and VL6 (R2). See application circuit diagrams for
detail connections.
