SC5260

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.

Features of the SC5260 are:(1)high performance technology; (2)low power consumption; (3)very high noise immunity; (4)wide operating temperature range: -30 C~70 C; (5)8 or 10 tri-state code address pins; (6)single resistor oscillator; (7)least external components.In no event shall Sensitron Semiconductor be liable for any damages that may result from an accident or any other cause during operation of the user's units according to the datasheet(s). Sensitron Semiconductor assumes no responsibility for any intellectual property claims or any other problems that may result from applications of information, products or circuits described in the datasheets.

The absolute maximum ratings of the SC5260 can be summarized as:(1)supply voltage:-0.3 to 6.0V;(2)storage temperature:-40 to 125;(3)input/output voltage:-0.3 to Vcc+0.3V;(4)operating temperature range:-30 to 70;(5)maximum power dissipation Pa 500 mW.SC5260 encodes the code address and data set at A0~A7, A8/D3, A9/D2, D1 and D0 into a special waveform and outputs it to the DOUT when any of the data pins is tied to high. This waveform is fed to the RF Modulator for transmission. The transmitted radio frequency is received by the RF demodulator and reshaped into the special waveform. SC5270 (or SC5272) is then used to decode the waveform and set the corresponding output pin(s).Thus completing a remote control encoding and decoding function.The built-in oscillator circuitry of SC5260 allows a precision oscillator to be constructed by connecting an external resistor between OSC and VCC pins. For SC5270 (or SC5272) to decode correctly the received waveform, the oscillator frequency of SC5270 (or SC5272) must be 1/16~4 (or 1/16~1/4) times that of the transmitting SC5260.
