M35054-XXXFP/M35055-XXXFP
SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
DESCRIPTION
The M35054-XXXFP and M35055-XXXFP are 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, external circuits can be decrease and character turbulence that occurs when superim­posing can be reduced. The processor is suitable for AV systems such as VTRs, LDs, and so on. It is a silicon gate CMOS process and M35054-XXXFP and M35055­XXXFP are housed in a 20-pin shrink SOP package. For M35054-001FP/M35055-001FP that are a standard ROM ver­sions of M35054-XXXFP/M35055-XXXFP 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. 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.
This is the pin for serial input of data and addresses for the display control register and the display data memory. Hysteresis input. Built-in pull-up resistor.
When “L”, this pin resets the internal IC circuit. Hysteresis input. 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 pin for test. Open this pin during normal operation. 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”. When using M35054-XXXFP, set “0” in any of DA7, DAD through DAF of addresses 0016 through EF16, and of DAE and DAF of ad-

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).

Supplemental explanation about display control register
(1) How to effect synchronous separation from composite video signals
Synchronous separation is effected as follows depending on the width of L-level of the vertical synchronous period.
1. Less than 8.4µs ······ Not to be determined to be a vertical synchronous signal.
2. Equal to or higher than 8.4µs but less than 15.6µs ······ When two clocks continue, if take place, it is “L” period is determined to be a vertical synchronization signal.
3. Equal to or higher than 15.6µs ······ It is “L” period is determined to be a vertical synchronous signal with no condition.
The determination is made at the timing indicated by V in Fig.4 either in case 2 or in case 3.

tion of character’s background color and raster color.

(2) Before setting registers at the starting of system, be sure to reset
the M35052-XXXSP/FP by applying “L” level to the AC pin.
(3) Power supply noise
When power supply noise is generated, the internal oscillator cir­cuit does not stabilize, whereby causing horizontal jitters across the picture display. Therefore, connect a bypass capacitor be­tween the power supply and GND.
(4) Synchronous correction action
When switching channel or in the special playback mode (quick playback, rewinding, and so on) of VTR, effect of synchronous correction becomes strong, and distortion of a character is apt to occur because the continuity of video signal is suddenly switched. When the continuity of video signal is out of order, erasure of displayed characters is recommended in a extreme short time to raise the quality of displayed characters.
(5) Notes on fSC signal input
This IC amplifies the subcarrier frequency (fSC) signal (NTSC, M­PAL system: 3.58MHz, PAL system: 4.43MHz) input to the OSCIN pin (17-pin) and generates the composite video signal internally. The amplified fSC signal can be destabilized in the following cases. a) When the fSC signal is outside of recommended operating con-
ditions. b) When the waveform of the fSC signal is distorted. c) When DC level in the fSC waveform fluctuates.
When the amplified signal is unstable, the composite video
signal generated inside the IC is also unstable in terms of syn-
chronization with the subcarrier and phase.
Consequently, this results in color flicker and lost synchroniza-
tion when the composite video signal is generated. Make note
of the fact that this may prevent a stable blue background from
being formed.
__
3) Wait 20 ms (the period necessary for the internal oscillation cir­cuit to stabilize) before entering data.
4) Set necessary data in other registers, and make the display RAM ready.
(6) Forbidding to stop entering the fSC signal
This IC doesn’t properly work if the fSC signal is not entered into the OSCIN pin (pin 17), so don’t stop the fSC signal so as to work the IC. To stop the IC, turn the display off (set 0 in the register DSPON (address F816).)
(7) Forbidding to set data during the period in which the internal
oscillation circuit stabilizes
a) To start entering the fSC signal when its input is stopped. b) To start oscillating the oscillation circuit for display when its
oscillation is stopped. (to assign “1” to the register STOP1 (ad­dress F816) when it is assigned “0”, or the like.)
c) To turn on the internal bias when it is turned off. (to assign “1”
to the register LEVEL1 (address F816) when it is assigned “0”.) There can be instances in which data are not properly set in the registers until the internal oscillation circuit stabilizes, so follow the steps in sequence as given below.
1) Set “0” in the register DSPON (address F816). (the display is turned off)
2) Effect the settings a), b), and c) given above.

Note for Supplying Power
(1)__Timing of power supplying to AC pin
The internal circuit of M35054-XXXFP/ M35055-XXXFP is reset when the level of the auto clear input pin AC is “L”. This pin is hysteresis input with the pull-up resistor. The timing about power supplying of AC pin is shown in Figure 16. tW is the interval after the supply voltage becomes 0.8 ✕ VDD or more and before the supply voltage to the AC pin (VAC) becomes 0.2 ✕ VDD or more. After supplying the power (VDD and VSS) to M35054-XXXFP/ M35055-XXXFP, the tW time must be reserved for 1ms or more.
