FUNCTIONAL DESCRIPTION
the voltage.
the system at low VDD less than power down detection voltage (2.5V typical).
The Serial I/F controls serial data from external data.
The Instruction Register stores instruction code from external.
The instruction decoder decodes instruction code and controls each blocks
The Data Buffer for Display stores data for display from external.
The Segment Driver generates driving waveform to Segment terminal on Display data.
The
The Common Driver generates driving waveform to Common terminal .
The Electrical Variable Resistance adjusts LCD Driving Voltage from V0 to V2.
The Key Scan Controller controls to input from external KEY data.
The Data buffer for key stores Key Data until next key data is stored.
The Oscillator is CR oscillator which generates the master clock.
The Reset circuit is type of detectable voltage. It resets internal circuit when the power turns on or drop
The Reset circuit is initializes the NJU6535 at Power ON and OFF. It generates reset signal to initialize
General output Driver
General output Driver.
generates “H” or “L” level to
General output
terminal on output data.
