SC50560
INFRARED REMOTE CONTROL TRANSMITTER OF 50560 CODE FORMAT
DESCRIPTION
The SC50560 is a remote control transmitter utilizing CMOS technology
housed in a 20-pin DIP or SOP package. A 4x8 key matrix and extension
bit inputs allow the transmission of up to 256 instructions. The
transmission code consists of 16 bits code (8 bits custom code and 8 bits
data code) and a leader code.
Pin assignments and application circuit of SC50560 are optimized for
easy PCB layout and cost saving advantage for remote control
applications.

FUNCTIONAL DESCRIPTION
SC50560 is capable of transmitting up to 256 different instructions and 8 bits custom codes using a 16-bit
PCM Code with a leader code. Furthermore, oscillation is normally stopped when there is no operating, thereby,
lower power dissipation.
1. TRANSMISSION CODE
SC50560 transmission code consists of a leader code, 8 bits custom code (C0 to C7) followed by a sync. bit
and 8 bits data code (D0 to D7) followed another sync. bit. The custom and the data codes are separated by a
separator. Please refer to the diagram below:
Figure 1. SC50560 Transmission Code Format
One transmission Code Word consists of a 19-bit pulse (that is the leader pulse plus the 16 bits code) and the
separator. It is transferred in a 63.4ms for as long as the key is depressed. Please refer to the diagram below:
Figure 2. SC50560 Detailed Code Word Format
LEADER CODE
The leader code is located at the beginning of the transmission code and is made up of 8.4ms HIGH &
4.2ms LOW pulse and is modulated in 38KHz providing easy identification of the reception code head bit at the
receiver.
