CMOS IC
LC75816E, 75816W
1/8 to 1/10 Duty Dot Matrix LCD Display Controllers/Drivers
with Key Input Function
Overview
The LC75816E and LC75816W are 1/8 to 1/10 duty dot
matrix LCD display controllers/drivers that support the
display of characters, numbers, and symbols. In addition to
generating dot matrix LCD drive signals based on data
transferred serially from a microcontroller, the LC75816E
and LC75816W also provide on-chip character display ROM
and RAM to allow display systems to be implemented easily.
These products also provide up to 2 general-purpose output
ports and incorporate a key scan circuit that accepts input
from up to 30 keys to reduce printed circuit board wiring.
Features
• Key input function for up to 30 keys (A key scan is
performed only when a key is pressed.)
• Controls and drives a 5 × 7, 5 × 8, or 5 × 9 dot matrix LCD.
• Supports accessory display segment drive (up to 65
segments)
• Display technique: 1/8 duty 1/4 bias drive (5 × 7 dots)
1/9 duty 1/4 bias drive (5 × 8 dots)
1/10 duty 1/4 bias drive (5 × 9 dots)
• Display digits: 13 digits × 1 line (5 × 7 dots)
12 digits × 1 line (5 × 8 dots, 5 × 9 dots)
• Display control memory
CGROM: 240 characters (5 × 7, 5 × 8, or 5 × 9 dots)
CGRAM: 16 characters (5 × 7, 5 × 8, or 5 × 9 dots)
ADRAM: 13 × 5 bits
DCRAM: 52 × 8 bits
• Instruction function
Display on/off control
Display shift function
• Sleep mode can be used to reduce current drain.
• Built-in display contrast adjustment circuit
• Switching between the key scan output port and general-
purpose output port functions can be controlled by
instructions.
• The frame frequency of the common and segment output
waveforms can be controlled by instructions.
• Serial data I/O supports CCB format communication
with the system controller.
• Independent LCD driver block power supply VLCD
• A voltage detection type reset circuit is provided to
initialize the IC and prevent incorrect display.
• The INH pin is provided. This pin turns off the display,
disables key scanning, and forces the general-purpose
output ports to the low level.
• RC oscillator circuit
• CCB is a trademark of SANYO ELECTRIC CO., LTD.
• CCB is SANYO’s original bus format and all the bus
addresses are controlled by SANYO.
Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other
parameters) listed in products specifications of any and all SANYO products described or contained
