EV1527 4 Bits RF Encoder Chip for Remote Control

Each IC EV1527 has guaranteed unique 1 million code possibility preprogrammed one time into it during manufacturing. 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.
