Overview
The LC 75810E and LC 75810T are 1/ 8 t o 1/ 10 duty dot
matrix LC D di splay cont rollers/drivers that support the
display of characters, numbers, and symbols. In addition to
generating dot m atrix LC D dri ve si gnals based on data
transferred serially from a microcontroller, the LC75810E
and LC 75810T al so provi de on-chi p charact er di splay
ROM and RAM to allo w d isplay system s to b e
implemented easily.

CGRAM: 16 characters (5 × 7, 5 × 8, or 5 × 9 dots)
DCRAM: 64 × 8 bits
ALATCH: 80 bits
• Instruction function
Display on/off control
Smooth up, down, left, and right scrolling of the display
• Provides a backup function based on power saving mode
• The frame frequency of the common and segment output
waveforms can be controlled by instructions.
• Built-in display contrast adjustment circuit
• Serial data input supports CCB format communication
with the system controller
• Independent LCD driver block power supply VLCD
• Provides a RES pin for IC internal initialization.
• RC oscillator circuit
• CCB is ON Semiconductor® ’s original format. All addresses are managed
by ON Semiconductor® for this format.
