Pin Function
No. Pin Name I/O
−
1 VSS1 Digital ground
2 XtalIN I Crystal oscillator connection (2fsc or 4fsc)
3 XtalOUT O Crystal oscillator connection (2fsc or 4fsc)
4 CTRL1 I Crystal oscillator input switching L: crystal oscillator mode, H: external clock mode
5 BLANK O Blank signal output Outputs a composite sync signal when MOD0 is high.
6 OSCIN I Connections for the coil and capacitor that form the oscillator that generates the character output dot clock.
7 OSCOUT O Connections for the coil and capacitor that form the oscillator that generates the character output dot clock.
8 CHARA I Character signal output
Enable input for serial data input Serial data input is enabled when low.
9 CS I
A pull-up resistor is built in (hysteresis input).
10 SCLK I Clock input for serial data I/O A pull-up resistor is built in (hysteresis input).
11 SIN I Serial data input A pull-up resistor is built in (hysteresis input).

12 VDD2 Analog power supply
13 CVOUT O Composite video signal output
−
14 NC Must be either connected to ground or left open.
15 CVIN I Composite video signal input
−
16 VDD1 +5 V digital power supply
17 SYNIN I Video signal input for the built-in sync separator circuit
18 SEPC O Built-in sync separator circuit bias voltage monitor pin
19 SEPOUT O Built-in sync separator circuit composite sync signal output
20 SEPIN I Inputs a vertical synchronization signal created by integrating the SEPOUT pin output signal.
The setting indicated by this pin takes priority in switching between the NTSC, PAL, PAL-M and PAL-N
21 CTRL2 I formats. A low level selects NTSC after a reset. The microprocessor command NTSC, PAL, PAL-M, or PAL-
N setting is valid. High = PAL-M format.
22 CTRL3 I Controls whether or not the VSYNC signal is input to the SEPIN input. Low = VSYNC input, high = VSYNC not input.
23 RST I System reset input
