OVERVIEW
The SED1560 series is a single-chip LCD driver for dot-
matrix liquid crystal displays. It accepts serial or 8-bit
parallel display data directly from a microprocessor and
stores data in an on-chip 166 × 65-bit RAM.
The SED1560 features 167 common and segment out-
puts to drive either a 65 × 102-pixel (SED1560) display
(4 rows × 6 columns with 16 × 16-pixel characters) or a
33 × 134-pixel (SED1561) display (2 rows × 8 columns
with 16 × 16-pixel characters) or a 17 × 150-pixel
(SED1562) display (1 row × 9 columns with 16 × 16
characters). In addition, two SED1560s can be con-
nected together to drive a 65 × 268-pixel graphics display
panel.
The SED 1560 series can read and write RAM data with
the minimum current consumption as it does not require
any external operation clock. Also, it has a built-in LCD
power supply featuring the very low current consump-
tion and, therefore, the display system of a high-perform-
ance but handy instrument can be realized by use of the
minimum current consumption and LSI chip configura-
tion.
The SED 1560 Series has the SED1560, SED1561 and
SED1562 available according to the duty.
