¡ Semiconductor MSC1200-01/1200V-01 FEDL1200V-03 ¡ Semiconductor MSC1200-01/1200V-01 30-Bit Duplex Controller/Driver with Digital/Analog Dimming and Keyscan Functions GENERAL DESCRIPTION The MSC1200-01/1200V-01 is a Bi-CMOS display driver for 1/2-duty vacuum fluorescent display tube. This device consists of a 64-bit shift register, latches, an analog dimming circuit, a digital dimming circuit, a keyscan circuit, and drivers. The interface with a microcomputer can be done only with four signal lines (CS, DATA I/O, CLOCK, and INT). Also, the DATA I/O and CLOCK signal lines can be shared with other peripherals by using the chip select function.

¡ Semiconductor MSC1200-01/1200V-01 FEDL1200V-03 PIN DESCRIPTIONS Pin Symbol Description 1V DD Power Supply 2V PARK Day/night switching pin. When the high level is input, the IC enters the night mode and the value determined by the analog or digital dimming circuit is used as the output duty. When the low level is input, the IC enters the day mode and the output duty is about 100%. Analog voltage input for determining the analog dimming value. When the analog dimming circuit is used, the output duty is determined by the analog voltage to be input to this pin. When only the digital dimming circuit is used, pull down this pin to GND. 3V DIM Chip select input. Only when the high level is input to this pin, interfacing with a microcomputer is available through "CLOCK" and "DATA I/O" pins. Therefore, 2 signal lines of "CLOCK" and "DATA I/O" can be shared with other peripherals. 4C S Serial clock input. Data is input-output through "DATA I/O" pin at the rising edge of the serial clock.5 CLOCK Serial data input-output. This pin enters output mode only when the keyscan mode is selected. It enters input mode when other mode is selected.6 DATA I/O Interrupt signal output to microcomputer. When any key is pressed or released, key scanning is started. After the completion of the one cycle, this pin goes to the high level and keeps the high level until keyscan stop mode is selected.

7 INT

Test signal input. As this pin has a built-in pull-up resistor, it must be left open or pulled up in the normal operation mode. When the low level is input to this pin, SEG1-30 go to the high level, and GRID1 and GRID2 go to the low level. (All segments go on.)

8 TEST1

Serial data output. Selecting this pin specifies the MSC1200V-01. The data from DATA I/O is shifted out on the rising edge of the shift clock with a delay of 64 bits in the shift register. This pin can be used for connecting the IC with a LED driver in series.

9 DATA OUT

(Option) When the VPARK pin is at the high level, the pulse with the duty ratio determin- ed by the analog or digital dimming circuit is output through this pin. When this pin is at the low level, the pulse with the duty ratio determined by external circuit is input to this pin. This pin has an internal active pull-up resistor, which becomes active only when the V PARK pin is at the low level. When the VPARK pin is at the low level, this pin receives blanking signal from external circuits, so that output duty cycle can be controlled. Selecting this pin speci- fies the MSC1200-01.

¡ Semiconductor MSC1200-01/1200V-01 FEDL1200V-03 FUNCTIONAL DESCRIPTION Power-on Reset The IC is initialized by the built-in power-on reset circuit at power-on. The status of the internal circuit after initialization is as follows; 1) Shift registers and latches are reset. 2) Analog dimming is selected. 3) Digital dimming data register is reset. 4) Display data inp ut mode is selected. Data Input Data input is valid only when the high level is applied to the "CS" pin. Input data is input into the shift register through "DATA I/O" pin at the rising edge of CLOCK. The data is automatically loaded to latches at the falling edge of "CS" signal.

Therefore, when digital dimming is used, mode setting is required before the V PARK pin is set to the high level. The output duty ratio for analog dimming is 12.5% maximum. The correspondence between threshold voltage and output duty ratio is shown in V DIN Threshold Dimming Voltage VS. PWM Duty Cycle.

¡ Semiconductor MSC1200-01/1200V-01 FEDL1200V-03 Keyscan Keyscanning is started only when depression or release of any key is detected in order to minimize noise caused by scanning signal. Then, keyscanning is continued until the keyscan stop mode signal is sent from a microcomputer. The INT pin goes to the high level at the completion of 1-cycle scanning after the keyscan start, so the (high level) signal sent from the INT pin can be used as an interrupt signal. [Keyscan Timing]

1 Cycle

Depress/Release Keyscan stop mode is selected. Note: Keyscanning cannot be stopped by selecting the keyscan stop mode only once if: - keyscanning is started after depression or release of any key is detected, and then - a key is depressed or released again before the keyscan stop mode is selected. To stop keyscanning, it is required to select the keyscan stop mode once again.

¡ Semiconductor MSC1200-01/1200V-01 FEDL1200V-03 Keyscan Data Output When keyscan data output mode is selected, "DATA I/O" pin is changed to an output mode. Then, 30 bits of keyscan data come out from "DATA I/O" pin synchronizing with the rising edge of the clock. After the completion of 30 bits data output, the IC returns to the display data input mode synchronizing with the falling edge of CS.
