NJU6535
FUNCTIONAL DESCRIPTION
(1) Description for each blocks
(1-1) Serial I/F
The Serial I/F controls serial data from external data.
(1-2) Instruction Reg.
The Instruction Register stores instruction code from external.
(1-3) Instruction Decoder.
The instruction decoder decodes instruction code and controls each blocks
(1-4) Data Buffer for Display.
The Data Buffer for Display stores data for display from external.
(1-5) Segment Driver / General output Driver.
The Segment Driver generates driving waveform to Segment terminal on Display data.
The General output Driver generates “H” or “L” level to General output terminal on output data.
(1-6) Common Driver.
The Common Driver generates driving waveform to Common terminal .
(1-7) Electrical Variable Resistance (E.V.R.)
The Electrical Variable Resistance adjusts LCD Driving Voltage from V0 to V2.
(1-8) Key Scan Controller.
The Key Scan Controller controls to input from external KEY data.
(1-9) Data buffer for Key.
The Data buffer for key stores Key Data until next key data is stored.
(1-10) CR Oscillator
The Oscillator is CR oscillator which generates the master clock.
(1-11) Reset Circuit
The Reset circuit is type of detectable voltage. It resets internal circuit when the power turns on or drop
the voltage.
The Reset circuit is initializes the NJU6535 at Power ON and OFF. It generates reset signal to initialize
the system at low VDD less than power down detection voltage (2.5V typical).
