SC5262
312 ADDRESS REMOTE CONTROL ENCODER
DESCRIPTION
The SC5262 is a remote control encoder paired with SC5272 utilizing
CMOS technology. It encodes data and address pins into a serial coded
waveform suitable for RF or IR modulation. SC5262 has a maximum of
12-bits of tri-state address pins providing up to 531,441(or 312) address
codes; thereby, drastically reducing any code collision and unauthorized
code scanning possibilities.
FEATURES
* Low power consumption and very high noise immunity
* Up to 12 tri-state code address pins or 6 data pins
* Wide operating voltage range(VCC=3V ~ 15V)
* Single resistor oscillator
* Latch or Momentary output type
ORDERING INFORMATION
APPLICATIONS
* Home/automation security system
* Remote control toys or for
industrial use
* Remote control fan
* Garage door controller

SC5262
Code word
A group of Code Bits is called a Code Word. A Code Word consists of 12 AD bits followed by one Sync. Bit.
The 12 AD bits are determined by the corresponding states of A0~A5 and A6/D5 ~ A11/D0 pins at the time of
transmission. When Data Type of SC5262 is used , the address bits will decrease accordingly. For example, in
the 3 Data Type where the address has 9 bits, the transmitting format is:
9 address bits 3 Data bits
Sync. Bit
SC5262/SC5272 has a maximum of 12 Address Bits including the 6 Address/Data bits. The following diagram
shows the code bits with their corresponding pins.
A6 A7 A8 A9 A10 A11
A0 A1 A2 A3 A4 A5
/D5 /D4 /D3 /D2 /D1 /D0
0 Data A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 A11 Sync
1 Data A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 A10 D0 Sync
2 Data A0 A1 A2 A3 A4 A5 A6 A7 A8 A9 D1 D0 Sync
3 Data A0 A1 A2 A3 A4 A5 A6 A7 A8 D2 D1 D0 Sync
4 Data A0 A1 A2 A3 A4 A5 A6 A7 D3 D2 D1 D0 Sync
5 Data A0 A1 A2 A3 A4 A5 A6 D4 D3 D2 D1 D0 Sync
6 Data A0 A1 A2 A3 A4 A5 D5 D4 D3 D2 D1 D0 Sync
The Code Bits A0~A5 and A6/D5 ~ A11/D0 are determined by the states of A0 ~ A5 and A6/D5 ~A11/D0 pins.
For example, when the A0(pin 1) is set to “1 ”(Vcc), the code bit A0 is synthesized as “1 ”bit. In the same
manner, when it (A0 pin) is set to “0 ”( Vss) or left floating, the Code Bit A0 is synthesized as a “0 ”or “f ” bit
respectively.
Code Frame
A Code Frame consists of 4 continuous code Words. When SC5262 detects “0”on the TE (meaning , the TE
is active “low”), it outputs a Code frame at Dout. If TE is still active at the time the Code Frame transmission
ends. SC5262 outputs another Code Frame. It should be noted that the Code Frame is synthesized at the time of
transmission.
Single Resistor Oscillator
The Build-in oscillator circuitry of SC5262 allows a precision oscillator to be constructed by connecting an
external resistor between OSC1 and OSC2 pins. For SC5272 to decode correctly the received waveform, the
oscillator frequency of SC5272 must be 2.5 ~8 times that of transmitting SC5262. The typical oscillator frequency
with various resistor values for both SC5262 and SC5272 are shown below:
