2 / 47 page  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 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 separa- tion. Please connect to +5V with the digital circuit power pin.
