EV1527 datasheet


The EV1527 is OTP Encoder utilizing CMOS technology process. EV1527 hai a maximum of 20 bits providing up to 1 million codes.It can reduce any code collision and unauthorized code scanning possibilities. An OTP (One-Time Programmable) encoder refers to a device or circuit that is designed to encode information using a one-time programmable method. OTP technology allows data to be programmed into a device only once, after which the programmed information becomes permanent and cannot be altered or erased.
