LC75806PT Datasheet | onsemi

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 munication 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 mon 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 ponents Industries, LLC. Semiconductor ponents Industries, LLC,...
