EV1527 DatasheetIf you want to make your own custom RF transmitter, you can use this chip. All you need is to add any ASK RF Transmitter, 12V battery and couple of other parts.
You can use any microcontroller to decode or use our ST3777 chip. We use the same chip in our 4 switch RF keypad.
Each IC EV1527 has gauranteed unique 1 million code possibility preprogrammed one time into it during manfacturing. The IC EV1527 gives much better result as compared to HT12E/PT2262 which are fixed code and does not need end user address configuration.
The IC EV1527 is called learning type since the receiver has to store its code before i can detect future packets. It gives better security.
