Segment Common Driver with Controller Character Display System
CMOS
GENERAL DESCRIPTION
SSD1801 single-chip CMOS driver with controller liquid crystal dot-matrix character display system. consists high voltage driving output pins driving Segments, Commons icon driving-Common. display lines characters with dots format. double height character mode line vertical scroll functions supported. SSD1801 displays character directly from internal 10,240 bits (256 characters dots) Character Generator (CGROM). character codes stored bits character lines) Data Display (DDRAM). User defined character loaded bits characters dots) Character Generator (CGRAM). addition, there bits Icon Icon display. Data/ Commands sent from general through software selectable 6800-/8080-series compatible 8-bit Parallel Interface Serial Peripheral Interface. SSD1801 embeds DC-DC Converter, Voltage Regulator, Voltage divider oscillator which reduce number external components. With special design minimizing power consumption size, SSD1801 suitable portable battery-driven applications requiring long operation period compact size.

FUNCTIONAL BLOCK DESCRIPTIONS
Command Decoder Command Interface
This module determines whether input data interpreted data command. Data directed this module based upon input pin. high, data written internal memories (DDRAM, CGRAM, ICONRAM). low, input D7-D0 interpreted Command will decoded written corresponding command register.
Parallel 6800-series Interface bits mode
