LC75806PT
CMOS IC
1/4 and 1/3-Duty LCD Display Driver
with Key Input Function
http://onsemi.com
Overview
The LC75806PT is 1/4 duty and 1/3 duty LCD display driver that can directly drive up to 304 segments and can
control up to 9 general-purpose output ports. This product also incorporates 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.)
• 1/4 duty 1/3 bias and 1/3 duty 1/3 bias drive schemes can be controlled from serial data.
• Capable of driving up to 304 segments using 1/4 duty and up to 231 segments using 1/3 duty.
• Switching between key scan output and segment output can be controlled from serial data.
• The key scan operation enabled/disabled state can be controlled from serial data.
• Switching between segment output port and general-purpose output port can be controlled from serial data.
• Switching between general-purpose output port, clock output port, and segment output port can be controlled
from serial data. (Up to 9 general-purpose output ports and up to one clock output port)
• Serial data I/O supports CCB format communication with the system controller. (Support 3.3V and 5V operation)
• Sleep mode and all segments off functions that are controlled from serial data.
• The frame frequency of the common and segment output waveforms can be controlled from serial data.
• Switching between RC oscillator operating mode and external clock operationg mode can be controlled from
serial data.
• Direct display of display data without the use of a decoder provides high generality.
• Built-in display contrast adjustment circuit.
• Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays.
• RES pin provided for forcibly initializing the IC internal circuits.
• CCB is ON Semiconductor® ’s original format. All addresses are managed
by ON Semiconductor® for this format.
• CCB is a registered trademark of Semiconductor Components Industries, LLC.
