SC3010
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.

Both the DOUT and the MDOUT are non-conducting (3-state outputs) when in the quiescent state. The Scan
Driver Outputs (KO0~KO7) are open drain n-channel and conduct when the circuit is in the quiescent state.
4. SYSTEM MODES
a). Combined System Mode (SMS=Low)
The KI and the C Sense Inputs have p-channel pull-up transistors (meaning they are normally in HIGH state).
They are pulled to LOW state when an output is connected, to them as a result of a legal key operation. A legal
key operation in the KI-KO or C-KO Matrix will initiate a debounce cycle. Once key contact has been established
for 18-bit time without any interruption, the Oscillator Enable Signal is latched and the key may be released. The
device is reset when there is an interruption during the 18-bit time period. At the end of the debounce cycle, KO
Outputs are switched off and two scan cycles begins.
When KI or C Input senses a low level output, a Latch-Enable Signal is fed to the System (C-Input) or
Command (KI-Input) Latches. After latching a system number, the device will generate the last command (i.e. all
command bits logic 1) in the selected system for as long as the key is pressed. Latching of a command number
causes the chip to generate this command together with the system number stored in the system latch. By
releasing the key, the device will be reset if no data is to be transmitted at the time. The complete code frame is
transmitted even if the key is released during code transmission.
b). Single System Mode (SMS=High)
In the Single System Mode, the KI-Sense Inputs are also pulled High by the p-channel pull-up transistors, as in
the Combined System Mode. The C-Sense Inputs, however, are disabled by switching off their pull-high
transistors. A system code is provided by a wired connection between the C-KO Matrix. The debounce cycle can
ONLY be started by any legal key operation in the KI-KO Matrix. Once the key contact has been established for
18-bit time without any interruption, the Oscillator-Enable Signal is latched and the key may be released. Any
interruption during the 18-bit time period resets the internal action.
At the end of the debounce cycle, the pull-up transistors in the KI-Lines are then switched off and the pull-up
transistors in the C-lines are turned ON for the first scan cycle. The wired connection in the C-matrix matrix is
then translated into a system number and stored in the system latch. At the end of the first scan cycle, 1) the C-
Input pull-up transistors are switched off and the inputs are again disabled, 2) KI-Sense Input pull-up transistors
are turned on. The command number is generated by the second scan cycle. This command number is then
latched and transmitted together with the system number.
5. KEY RELEASE DETECTION
An additional control bit is complemented after key release. This additional control bit tells the decoder that the
next code is a new command. This feature is important in cases where more digits are needed to be inputted (i.e.
Teletext channel numbers or Viewdata pages). The extra control bit will only be complemented after the
completion of at least one code transmission. The scan cycles are repeated before every code transmission; thus,
even with the Take Over of key operation during the code transmission, the correct system and command
numbers are generated.
6. RESETTING THE DEVICE
The device will immediately reset under the following conditions:
1). A key is released during the debounce time
2). A key is released between two codes
