1/2,1/3 DUTY DRIVER WITH SCAN
GENERAL DESCRIPTION
NJU6435 duty driver segment type panel with scan function.
Display data input data comunicated serial data transmission, therefore, comunication between NJU6435 performed only lines.
80-segment 120-segment displayed 40-segment driver 2-common 3-common driver.
scan function scanning keys data transferd CPU.
NJU6435 design simple front panel, therefore easy apply mounted audio, general audio other products which have display input.

FUNCTIONAL DESCRIPTION
Operation each block
(1-1) Osci lati Circuit
Oscillation connecting external resister capacitor.
This circuits supply basical clock signal other circuits like common driver segment driver scan circuits.
(1-2) Dividing Circuit
This circuit divide oscillating frequency, generate common segment output timing signals.
(1-3) Common Driver
Output common driving signal LCD.
(1-4) Segment Driver
Output segment driving signal LCD.
signal output according latched data.
(1-5) Shift-Register
During signal "H", data input shift-register synchronousing shift clock terminal.
When input, data countet
(1-6) Counter circuit
This circuits generate scanning timing, transferd scan shift resister.
(1-7) Decorder
Decording counter output generate scan signal.
(1-8) Input Latch
When depressed, decoder output transfer latch.
(1-9) Scan Shift Resister
Output data sent from counter circuits input latch serial format through DI/DO port.
(2-1) Mode each Terminal controlled signal

Scan Mode (Output) When input, Interrupt signal Output enforced effective Input Signal Output Mode (Output) After interrupt signal output, input data output from this terminal syncronized clock signal.
(2-2) Initialization
NJU6435 series doesn't have initialization function display data. Therefore, data Shift Register Latch connected segment driver
unfixed when power turns
avoide meaning display, R/W="H" INH="L" status should kept during display data transmission from controller NJU6435.
