s DESCRIPTION
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.
The SED1532 can display the 65x200-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.
No external operation clock is required for RAM read/write operations. 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.
s FEATURES
q 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)
q RAM capacity: 65 × 132 = 8580 bits
q High-speed 8-bit microprocessor interface allowing direct connection to both the 8080 and 6800.
q Serial interface
q Many command functions: Read/Write Display Data, Display 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 Direction, Power Save
