EG Micro EG301

EG301 is a rolling code encoder IC designed for Remote Keyless Entry (RKE) systems. It features high security, a compact package, and ultra-low standby power consumption. The chip employs 64-bit encryption internally, making it impossible to crack. Standby current of less than 1uA ensures extended battery life. An integrated internal EEPROM allows flexible configuration of different operating states, with data retention of over 10 years.
