The difference between remote controls that use different chips

Wireless remote controllers are devices used to emit signals for remote control. Currently, the two most popular types in the market are infrared remote control mode, commonly used in home appliances, and radio frequency wireless remote control mode, commonly used in anti-theft alarm systems, door and window controls, car remote controls, and more.

Let’s first get to know the types of remote controllers commonly used in the market today, which can be distinguished by IC.

Fixed-code wireless remote controller: commonly used ICs include PT2262, PT2264, SC2262, SC2260, HS2262, and LX2262.

Learning-code wireless remote controller: commonly used ICs include EV1527, PT2240, EV527, and SC1527.

Rolling-code wireless remote controller: commonly used ICs include HSC301 and 201.

The difference between the three types of remote controllers lies in the coding address, which affects the security and confidentiality of the controller.

Fixed-code wireless remote controllers can only be programmed with 6561 codes.

Learning-code wireless remote controllers have millions of different codes available.

Rolling-code wireless remote controllers have unique coding addresses that cannot be repeated.
