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.

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.

PCB WIRE LAYOUT SCHEMATIC
Transmitting tube output ground line
SC3010
The above IC only use to hint, not to specified.
The transmitting tube ground line and IC ground line should
layout separated or overstriking ground line.
Note:
* In wire layout, the power filter capacitor should near to IC.
* In wire layout, should avoid power line and ground line too long.
* Recommended infrared transmit unit and IC ground line should layout separated, or overstriking lines.
* The emitter of triode connect 1 resistor at least.
* Recommended triode use 9014.
