FUNCTIONAL DESCRIPTION
SC50462 is a sending signal IC on infrared remote control. Consisting of timing generating circuit, scan signal
generating circuit, key input encoder, instruction decoder, custom code circuit, code encoder, and output buffer. It
has 8*8 key matrix input and custom code with 16 bit PCM which shows 76 instructions.76Instruction are devided
in 64 one shot signal and 12 2-shot signal.
When Input Signal(I1~I8) and/or in combination with the Scan Signals(S1~S8) are activated, SC50462 checks
the ID and the Custom Code Bits--
4
C
and
5
C
--setting before finally sending out the remote control signal.

CNTR
OUTPUT
The
CNTR
Pin is the LED transmission Indicator. This means that Whenever a valid transmission is sent, the
LED lights up. The
CNTR
output becomes “L” in the 7
th
pulse-rising and “H” in the 17
th
pulse-rising.
