LCD Drivers LCD Driver, 1/3, 1/4 Duty, with Key Input

LCD Driver 64-SPQFP (10x10), 64-SQFP

Key input function for up to 30 keys (A key scan is performed only when a key is pressed.)
1/3 duty and 1/4 duty drive schemes can be controlled from serial data.
1/2 bias and 1/3 bias drive schemes can be controlled from serial data.
Capable of driving up to 126 segments using 1/3 duty and up to 164 segments using 1/4 duty.
Sleep mode and all segments off functions that are controlled from serial data.
Switching between key scan output and segment output can be controlled from the serial data.
The key scan operation enabled/disabled state can be controlled from the serial data.
Switching between segment output port and general-purpose output port can be controlled from serial data.
The common and segment output waveform frame frequency can be controlled from the serial data.
Switching between RC oscillator mode and external clock mode can be controlled from the serial data.
Serial data I/O supports 'computer control bus' format communication with the system controller.
Direct display of display data without the use of a decoder provides high generality.
Independent VLCD for the LCD driver block.
Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays.
