Description
Power Supply
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.

PARK

V
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.
4
CS
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 V
PARK
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
V
PARK
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.
