EV1527 Datasheet

The remote control transmitter is small hand held unit with 4 keys which works on 12V battery to give good range of operation.

When a key is pressed, the IC is connected to power supply battery and it starts transmitting packets at 433 Mhz frequency consisting of its ID and Data byte which indicates which key was pressed. This information is used in remote control applications.

Each transmitter has pre-programmed unique ID set during manufacturing and cannot be changed. The receiver board usually stores the transmitter ID in its memory before so receiver only responds to known transmitter IDs for secure applications.

The RF part inside remote is SAW based 433 Mhz transmitter, which can be received by any 433 Mhz type ASK RF Receiver followed by decoder chip.
