The Microchip Technology HCS410/ST is a specialized integrated circuit designed for secure entry and access control systems. It utilizes the KEELOQ® code hopping system, providing a 32-bit unidirectional code hopping mechanism with a 37-bit non-encrypted portion. The device supports a 69-bit transmission length and programmable 28/32-bit serial numbers.
Operating within a voltage range of 2.0V to 6.6V, the HCS410/ST features three switch inputs for seven functions and includes an on-chip tunable RC oscillator with ±10% tolerance. It also offers 64-bit user EEPROM for transponder mode and a battery-low LED indication.
This IC is available in an 8-TSSOP package, suitable for surface mount applications. Its design makes it ideal for automotive remote entry systems, gate and garage openers, and electronic door locks, offering a secure and reliable solution for physical and logical access control.
Key features include read-protected encoder keys, secure learning seeds, and asynchronous transponder communication. The device is protected against reverse battery and supports PWM or Manchester RF encoding.
