M35053-xxxsp/fp screen character and pattern display controllers mitsubishi microcomputers 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 separa- tion) 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 suit- able 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 M35053- xxxsp/fp respectively, the character pattern is also mentioned. features ? screen composition .............................. 24 characters 5 10 lines, 32 characters 5 7 lines ? number of characters displayed .................................. 240 (max.) ? character composition ..................................... 12 5 18 dot matrix ? characters available ............................................. 256 characters ? character sizes available .................... 4 (horizontal) 5 4 (vertical) ? display locations available horizontal direction ............................................... 240 locations vertical direction ................................................... 256 locations ? blinking ................................................................. character units cycle : approximately 1 second, or approximately 0.5 seconds duty : 25%, 50%, or 75% ? data input .............................. by the serial input function (16 bits) ? coloring background coloring (composite video signal) ? blanking total blanking (14 5 18 dots) border size blanking character size blanking ? synchronizing signal composite synchronizing signal generation (pal, ntsc, m-pal) ? 2 output ports (1 digital line) ? oscillation stop function it is possible to stop the oscillation for synchronizing signal generation ? built-in half-tone display function ? built-in reversed character display function ? built-in decoder (ntsc only) ? built-in encoder (ntsc only) ? built-in synchronous correction circuit ? built-in synchronous separation circuit application tv, vcr, movie pin configuration (top view) rev.1.1 M35053-xxxfp 20 19 18 17 16 15 14 13 12 11 1 2 3 4 5 6 7 8 9 10 cp1 testa cs sck sin ac v dd2 cvideo lecha cvin v dd1 hor cp2 oscin v ss p1 p0 testb edo v ss M35053-xxxsp 20 19 18 17 16 15 14 13 12 11 1 2 3 4 5 6 7 8 9 10 cp1 testa cs sck sin ac v dd2 cvideo lecha cvin v dd1 hor cp2 oscin v ss p1 p0 testb edo v ss outline 20p4b outline 20p2q-a ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?
M35053-xxxsp/fp screen character and pattern display controllers mitsubishi microcomputers 2 pin description 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 2v p-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 (f sc ) 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 separa- tion. please connect to +5v with the digital circuit power pin. symbol osc1 testa __ cs sck sin __ ac v dd2 cvideo lecha cvin v ss edo testb p0 p1 v ss oscin cp2 hor v dd1 pin name clock input test pin chip select input serial clock input serial data input/ output auto-clear input power pin composite video signal output character level input composite video signal input earthing pin encode data output test pin port p0 output port p1 output earthing pin f sc input pin for synchronous signal generation filter output horizontal synchro- nizing signal input power pin input/ output input input input input/ output input output input input output output output input output input

M35053-xxxsp/fp screen character and pattern display controllers mitsubishi microcomputers 27 (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 cir- cuit does not stabilize, whereby causing horizontal jitters across the picture display. therefore, connect a bypass capacitor be- tween 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 f sc signal input this ic amplifies the subcarrier frequency (f sc ) signal (ntsc, m- pal system: 3.58mhz, pal system: 4.43mhz) input to the oscin pin (17-pin) and generates the composite video signal internally. the amplified f sc signal can be destabilized in the following cases. a) when the f sc signal is outside of recommended operating con- ditions. b) when the waveform of the f sc signal is distorted. c) when dc level in the f sc 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. (6) forbidding to stop entering the f sc signal this ic doesnt properly work if the f sc signal is not entered into the oscin pin (pin 17), so dont stop the f sc signal so as to work the ic. to stop the ic, turn the display off (set 0 in the register dspon (address f8 16 ).) (7) forbidding to set data during the period in which the internal oscillation circuit stabilizes a) to start entering the f sc 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 (ad- dress f8 16 ) 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 f8 16 ) 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 f8 16 ). (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 cir- cuit to stabilize) before entering data. 4) set necessary data in other registers, and make the display ram ready.
