REMOTE CONTROL ENCODER
DESCRIPTION
The SC5260 is a remote control encoder paired with either
SC5260 or SC5272 utilizing COMS Technology. It encodes data and
address pins into a serial coded waveform suitable for RF
modulation. SC5260 has a maximum of 10 bits tri-state address
pins providing up to 59,049 (or 310) address codes; thereby,
drastically reducing any code collision and unauthorized code
scanning possibilities.
SC5260 is one of the first generation of Encoder/
Decoder ICs. When paired with SC5270, this encoder/decoder
(SC5260/SC5270) pair can operate at very wide temperature range
(see Features). Thus, this very important feature enables your
Encoder/Decoder to operate under the worst environmental
condition.
FEATURES

PIN DESCRIPTION
Pin No. Symbol I/O Description
1~8 A0~A7 I Code Address Pin Nos.0~7
These eight tri-state pins ate detected by SC5260 to determine the
encoded waveform bit0~bit7. Each bit can be set to “0”, “1”, or
“f”(floating).
10~11 A8/D3~A9/D2 I/PL* Code Address pin Nos.8~9/Data Pin Nos.3~2.
These two tri-state pins are detected by SC5260 to determine the
encoded waveform bit8~bit9. When these pins ate used as address
pins (as in SC5260-R2), they can be set to “0”, “1”, or “f” (floating).
When these pins are used as data pins (as in SC5260-R4), they can
only be set to “0” or “1”.
12~13 D1, D0 I/PL Data Pin Nos. 1~0. These pins can only be set to “0” or “1”.
14 OSC I Oscillator Pin A resistor connected between the OSC Pin and the VCC
determines the fundamental frequency of the SC5260.
15 DOUT O Data Output Pin. The encoded waveform is serially outputted to this
pin. When SC5260 is not transmitting, DOUT outputs low (VSS)
voltage.
16 VCC Positive Power Supply
9 VSS Negative Power Supply
Note: PL -- Pull-low Resistor is connected internally
PL* -- If those two pins are used as Data Pins (SC5260-R2), pull-low resistor is connected internally;
otherwise, no pull-low resistor is connected.
