Description
1
VSS
Ground
Ground connection
2
OSCIN
LC oscillator
Connections for the coil and capacitor that form the oscillator that generates the character
3
OSCOUT
output horizontal dot clock.
4
CTRL1
Clock input control
Control input that switches between LC oscillator mode and clock input mode
Low: LC oscillator mode, high: clock input mode
5
TESTIN
Test control input
Test mode control input (The IC operates in test mode when this input is high.)
6
CS
Enable input
Serial data input enable input
Low: active (This input has hysteresis characteristics.)
7
SCLK
Clock input
Serial data input clock input (This input has hysteresis characteristics.)
8
SIN
Data input
Serial data input (This input has hysteresis characteristics.)
9
CKOUT
Clock output
LC oscillator clock monitor output
This signal is output when RST is low.
10
BLK4
Blanking signal output
Blanking signal output (system 2)
Functions as the system 4 blanking data signal output in 4-system mode.
11
CHA4
Character data output
Character data signal output (system 2)
Functions as the system 4 character data signal output in 4-system mode.
12
NC
Unused
Must be left open or tied to ground in normal operation.
13
NC
Unused
Must be left open or tied to ground in normal operation.
14
BLK3
Blanking signal output
Blanking signal output (system 1)
Functions as the system 3 blanking data signal output in 4-system mode.
15
CHA3
Character data output
Character data signal output (system 1)
Functions as the system 3 character data signal output in 4-system mode.
16
BLANK
Blanking signal output
Blanking signal output (blanking signal for RGB output)
Functions as the system 2 blanking data signal output in 4-system mode.
17
R
Character data output
Character data (R) signal output
Functions as the system 2 character data signal output in 4-system mode.
18
G
Character data output
Character data (G) signal output
Functions as the system 1 blanking data signal output in 4-system mode.
19
B
Character data output
Character data (B) signal output
Functions as the system 1 character data signal output in 4-system mode.
20
OUTMOD
Output control input
Control input that switches between RGB output and 4-system output
Low: RGB output, high 4-system output
21
VSYNC
Vertical synchronizing
Vertical synchronizing signal input (This input has hysteresis characteristics.)
signal input
22
HSYNC
Horizontal synchronizing
Horizontal synchronizing signal input (This input has hysteresis characteristics.)
signal input
23
RST
Reset input
System reset signal input (This input has hysteresis characteristics.)
24
VDD
Power supply
Power supply connection (+5 V)
Note: 1. Built-in pull-up resistors can be specified for inclusion in the CS (pin 6), SCLK (pin 7), SIN (pin 8), and RST (pin 23) pins as mask options.
2. In clock input mode (when CTRL1 is high), the function that holds the OSCIN (pin 2) pin high during an oscillator reset is stopped.
