M35052-XXXSP/FP

SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS

DESCRIPTION

The M35052-XXXSP/FP is TV screen display control IC which can
be used to display information such as number of channels, the date
and messages and program schedules on the TV screen.
In particular, owing to the built-in SYNC-SEP (synchronous separa­tion) circuit, the synchronous correction circuit, the Decoder circuit,
and to the Encoder circuit, external circuits can be decrease and
character turbulence that occurs when superimposing can be reduced.
The processor can conform to the EDS broadcast service and is suit­able for AV systems such as VTRs, LDs, and so on.
It is a silicon gate CMOS process and M35052-XXXSP is housed in
a 20-pin shrink DIP package, M35052-XXXFP is housed in a 20-pin
shrink SOP package.
For M35052-001SP/FP that is a standard ROM version of M35052­XXXSP/FP respectively, the character pattern is also mentioned.

SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS

Function

This is the filter output pin 1.
This is the pin for test. Connect this pin to GND during normal operation.
This is the chip select pin, and when serial data transmission is being carried out, it goes

to “L”. Hysteresis input. Includes built-in pull-up resistor.

__

When CS pin is “L”, SIN serial data is taken in when SCK rises. Hysteresis input. Built-in
pull-up resistor is included.

This is the pin for serial input of data and addresses for the display control register and
the display data memory. Also, serially outputs decode data according to the settings in
the relevant registers (serial I/O).

When “L”, this pin resets the internal IC circuit. Hysteresis input. Includes built-in pull-up
resistor.

Please connect to +5V with the analog circuit power pin.
This is the output pin for composite video signals. It outputs 2VP-P composite video

signals. In superimpose mode, character output etc. is superimposed on the external
composite video signals from CVIN.

This is the input pin which determines the “white” character color level in the composite
video signal.

This is the input pin for external composite video signals. In superimpose mode, character
output etc. is superimposed on these external composite video signals.

Please connect to GND using circuit earthing pin.
This is the output pin for encode data. It outputs three-valve data.
This is the pin for test. Connect this pin to GND during normal operation.
This pin outputs the port output or BLNK1 (character background) signal.
This pin outputs the port output or CO1(character) signal.
Please connect to GND using circuit earthing pin (Analog side).
This is the input pin for the sub-carrier frequency (fSC) for generating a synchronous

signal.
A frequency of 3.580MHz is needed for NTSC, and a frequency of 4.434MHz in needed
for PAL and 3.576MHz is needed for M-PAL.

Filter output pin 2.
This is the input pin for external composite video signals. This pin inputs the external

video signal clamped sync-chip to 1.5V, and internally carries out synchronous separa­tion.

Please connect to +5V with the digital circuit power pin.

SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS

MEMORY CONSTITUTION

Address 0016 to EF16 are assigned to the display RAM, address F016
to F816 are assigned to the display control registers.
The internal circuit is reset and all display control registers (address
F016 to F816) are set to “0” and display RAM (address 0016 to EF16)
are RAM erased when the AC pin level is “L”.

__

MITSUBISHI MICROCOMPUTERS

M35052-XXXSP/FP

Set “0” in any of DA7, DAD through DAF of addresses 0016 through
EF16, and of DAE and DAF of addresses F016 through F816.
Setting the blank code “FF16” as a character code is an exception.
TESTn (n : a number) is MITSUBISHI test memory, so be sure to
observe the setting conditions.
