M35053-XXXSP/FP
SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
DESCRIPTION
The M35053-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 M35053-XXXSP is housed in a 20-pin shrink DIP package, M35053-XXXFP is housed in a 20-pin shrink SOP package. For M35053-001SP/FP that is a standard ROM version of M35053­XXXSP/FP respectively, the character pattern is also mentioned.

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 digital three-value data or composite video signals. 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.

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”.

Notes 1. In dealing with the internal synchronization, cut off external video signals outside the IC. The leakage of external input video signals
can be avoided.
Notes 2. In displaying color superimposition, enter into the OSCIN pin the fSC signal that phase-synchronizes with the color burst of the
composite video signals (input to the CVIN pin).
Notes 3. Erases all the display RAM. The character code turns to blank-FF16, the encode data bit and the blinking bit turn to “1” respectively,
