Terminal Description
pin 1: VSS 1 : Digital system ground.
pin 2: Xtal IN : Connect the crystal to generate the internal syn-
chronization signal.
Or input an external clock (2fsc or 4fsc).
pin 3: Xtal OUT : Connect the crystal.
pin 4: CTRL 1 : Inputs the crystal/oscillator selection signal.
Low = crystal oscillator mode.
High = external clock mode.
pin 5: BLANK : This terminal outputs the blank signal.
pin 6: OSC IN : Connect the coil and capacitor to form the os-
cillator that generates the dot clock.
pin 7: OSC OUT : Connect the coil and capacitor to form the os-
cillator that generates the dot clock.
pin 8: CHARA : Outputs the character signal.
pin 9: CS : Serial data input is enabled when low.
pin 10: S CLK : Serial data input clock input.
pin 11: S IN : Serial data input.
pin 12: VDD 2 : Analog system power supply.
pin 13: CV OUT : Composite video signal output.
pin 14: NC : Must be either connected to ground or left open.
pin 15: CV IN : Composite video signal input.
pin 16: VDD 1 : +5 V. Digital system power supply.
pin 17: SYN IN : Video signal input for the built-in sync separator
circuit.
pin 18: SEP C : Sync separator circuit bias voltage monitor pin.
pin 19: SEP OUT : Built-in sync separator circuit composite sync sig-
nal output.
pin 20: SEP IN : Inputs a vertical synchronization signal created
by integrating the SEP OUT pin output signal.
pin 21: CTRL 2 : NTSC/PAL-M switching input.
High = PAL-M format.
Low = NTSC format.
pin 22: CTRL 3 : SEPIN input control.
High = V-SYNC not input.
Low = V-SYNC input.
pin 23: RST : System reset input.
pin 24: VDD 1 : +5 V digital system power supply.

Terminal Description
pin 1: CS :IN: The chip select command input.
pin 2: S CLCK :IN : Serial clock input.
pin 3: SI :IN: Serial data input.
pin 4: SO : O : Serial data output.
pin 5: GND : - : Ground.
pin 6: ORG :IN: Internal organization to decide the word
length.
pin 7: NU : - : Not in use.
pin 8: VCC : - : Positive supply voltage.
