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.

__
Pin name Clock input Test pin input Chip select input Serial clock input Serial data input
Input/ Output Input -- Input Input Input This is the filter output pin 1.
Function
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" __ display RAM (address 0016 to EF16) and 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 addresses F016 through F816. Setting the blank code "FF16" as a character code is an exception. When using M35055-XXXFP, set "0" in any of DAD through DAF of addresses 0016 through EF16, and of DAE and DAF of addresses F016 through F816. TESTn (n : a number) is MITSUBISHI test memory, so be sure to observe the setting conditions.

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 8.4s ****** Not to be determined to be a vertical synchronous signal. 2. Equal to or higher than 8.4s but less than 15.6s ****** 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 15.6s ****** 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.

(2) Before setting registers at the starting of system, be __ to reset sure 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 conditions. 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 synchronization with the subcarrier and phase. Consequently, this results in color flicker and lost synchronization when the composite video signal is generated. Make note of the fact that this may prevent a stable blue background from being formed. (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.
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.

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.
Before starting input from the microcomputer, the waiting time (ts) must be reserved for 500ms after the supply voltage to the __ AC pin becomes 0.8 ! VDD or more. (2) Timing of power supplying to VDD1 pin and VDD2 pin The power need to supply to VDD1 and VDD2 at a time, though it is separated perfectly between the VDD1 as the digital line and the VDD2 as the analog line.
