M35061-XXXSP/FP
SCREEN CHARACTER and PATTERN DOSPLAY CONTROLLERS
DESCRIPTION
M35061-XXXSP/FP is CATV screen display control IC which can
display 40 (horizontal)
!
17 (vertical). It has built-in SYRAM which
can be used with character ROM.
It uses a silicon gate CMOS process and M35061-XXXSP housed in
a small 32-pin shrink DIP package, and M35061-XXXFP housed in
a small 32-pin shrink SOP package. For M35061-002SP/FP that is
a standard ROM version of M35061-XXXSP/FP, the character pat-
tern is also mentioned.

Function
These input pins determine address and data of display control register and display
data memory 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 +5 V.
Ground pin. This pin must be connected to 0 V.
This pin outputs the composite video signal. The output signal is 2 V
P-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 pin inputs the external composite video signal. In superimpose mode, this pin’s
signal consists of the OSD signal combined with the external composite video signal.
This pin inputs the external composite video signal. This pin inputs the clamped
external video signal, sync-sep internal.
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 +5 V.
This is filter output pin 2.
These are the sub-carrier oscillation (fsc) input pins for synchronous signal generating.
NTSC (3.580 MHz), PAL (4.434 MHz), M-PAL (3.576 MHz) (Note).
Control the phase changing by scanning line by PAL, M-PAL method.
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.
