These input pins determine address and data of the Display RAM, Control RAM, and
Overlay RAM (SYRAM) by 8-bit parallel. Hysteresis input is required.
When this input pin transitions from “H” to “L”, the device is reset. Built-in a pull-up
resistor. Hysteresis input is required.
Digital power supply pin. This pin must be connected to + 5V.
Ground pin. This pin must be connected to 0V.
This pin outputs the composite video signal. The output signal is 2Vp-p. In superim-
pose mode, this pin’s signal consists of the OSD signal combined with the input
composite signal CVIN.
This input pin is used for controlling the “white” character color level of the OSD signal.
This input pin is used for controlling the “black” character color level of the OSD signal.
This input pin is used for the superimpose mode. An external composite signal may be
input through this pin and mixed with the internally generated OSD signal.
This input pin is used to input the same signal as CVIN. The horizontal and vertical
sync signals are then extracted internally within the device.
This input pin is used to determine the slice voltage for extracting the sync signals from
the video composite signal.
This is filter output pin 1.
Analog power supply pin. This pin must be connected to +5V.
This is filter output pin 2.
These are the pins for attaching an external oscillator circuit for generating the
synchronization signal:
NTSC (3.580MHz), PAL (4.434MHz), M-PAL (3.576MHz).
Factory test pin. The pin must be connected to GND.
This output pin can be configured to port P0 or YM output.
This output pin can be configured to port P1 or BLNK output.
This output pin can be configured to port P2 or B output.
This output pin can be configured to port P3 or G output.
This output pin can be configured to port P4 or R output.
This output pin can be configured to port P5 or CSYN output.
Factory test pin. The pin must be connected to GND.
This pin is enabled when the CS pin is “L”. Data input to pins AD0 to AD7 is latched at
the rising edge of this signal. This pin is hysteresis input.
This is chip selection input pin. When this pin is “L”, transmission is enabled. This pin is
hysteresis input.
