SED1530 Series  
tions. Accordingly, this driver can be operated with a minimum  
current consumption and its on-board low-current-consumption  
liquid crystal power supply can implement a high-performance  
handy display system with a minimum current consumption and a  
smallest LSI configuration.  
Two types of SED1530 series are available: one in which common  
outputs are arranged on a single side and the other in which common  
outputs are arranged on both sides.  
OVERVIEW  
The SED1530 series is a single-chip LCD driver for dot-matrix  
liquid crystal displays (LCD’s) which is directly connectable to a  
microcomputer bus. It accepts 8-bit serial or parallel display data  
directly sent from a microcomputer and stores it in an on-chip  
display RAM. It generates an LCD drive signal independent of  
microprocessor clock.  
The use of the on-chip display RAM of 65 × 132 bits and a one-to-  
one correspondence between LCD panel pixel dots and on-chip  
RAM bits permits implementation of displays with a high degree of  
freedom.  
As a total of 133 circuits of common and segment outputs are  
incorporated, a single chip of SED1530 series can make 33 × 100-  
dot (16 × 16-dot kanji font: 6 columns × 2 lines) displays, and a single  
chip of SED1531 can make 65 × 132-dot (kanji font: 8 columns x 4  
lines) displays when the SED1531 is combined with the common  
driver SED1635.  
FEATURES  
• Direct RAM data display using the display RAM. When  
RAM data bit is 0, it is not displayed. When RAM data bit  
is 1, it is displayed. (At normal display)  
• RAM capacity: 65 × 132 = 8580 bits  
• High-speed 8-bit microprocessor interface allowing direct  
connection to both the 8080 and 6800.  
• Serial interface  
The SED1532 can display the 65 × 200-dot (or 12-column by 4-line  
Kanji font) area using two ICs in master and slave modes. As an  
independent static indicator display is provided for time-division  
driving, the low-power display is realized during system standby  
and others.  
• Many command functions: Read/Write Display Data, Dis-  
play ON/OFF, Normal/Reverse Display, Page Address Set,  
Set Display Start Line, Set Column Address, Read Status,  
All Display ON/OFF, Set LCD Bias, Electronic contrast  
Controls, Read Modify Write, Select Segment Driver Direc-  
tion, Power Save  
No external operation clock is required for RAM read/write opera-
