INFRARED REMOTE CONTROL TRANSMITTER OF RC5 CODE FORMAT
DESCRIPTION
SC3010 is a remote control transmitter utilizing CMOS
Technology specially designed for use on general purpose (RC-5)
infrared applications with low voltage supply and large debounce
time. SC3010 supports 32 systems. Each system has a maximum of
64 commands; thus, SC3010 can provide up to a total of 2,048
commands.

FUNCTIONAL DESCRIPTION
1. KEY INPUT OPERATION
A Key Input Operation may be considered legal or illegal depending on the keys pressed. For key
interconnection refer to the application circuit diagram in APPLICATION CIRCUIT SECTION. The maximum
value of the switched key contact series resistance is 7k.
a). Legal Key Input
A legal key input operation enables the device to activate the corresponding codes. A key input operation is
considered as legal if it is 1). a connection of one K-Input (KI0~KI7) to one K-Output (KO0~KO7), or 2).a

3). During Matrix Scanning
a). A key is released while one of the drivers outputs is in the low ohmic state (Logic 0)
b). A key is released before that key has been detected.
c). There is no wired connection in the C-KO Matrix when SMS is in High State.
7. OSCILLATOR
The OSC is a 1-pin oscillator input/output terminal. The oscillator is constructed by connecting in series a
ceramic resonator like TOKO CRK429.
8. TEST MODE
When T1, T2 and OSC Pins are in HIGH State, the circuit initializes. All internal nodes except for the LATCH
are defined. The latch is defined when a scan cycle starts by pulling down a KI or a C Input while the oscillator is
active.
If the debounce cycle has been completed, then the scan cycle can be accomplished 3x23 times faster by
setting the T1 to HIGH. If the scan cycle has been completed, the Latch contents can be read 3x27 times faster
by setting the T2 to HIGH.
