The Microchip Technology HCS410T/ST is a specialized integrated circuit designed for secure entry systems, utilizing the KEELOQ® code hopping system. This device functions as both an encoder and a transponder, offering bi-directional challenge-and-response capabilities for enhanced security in access control applications.
Key features include a wide operating voltage range of 2.0V to 6.6V, programmable 64-bit encoder keys, and a 69-bit transmission length. The IC supports 32-bit unidirectional code hopping with a 37-bit non-encrypted portion. It also includes a programmable 28/32-bit serial number and a 60/64-bit read-protected seed for secure learning. The device incorporates three IFF encryption algorithms and operates with asynchronous transponder communication.
Packaged in an 8-TSSOP surface-mount configuration, the HCS410T/ST is suitable for various applications such as automotive remote entry systems, alarm systems, immobilizers, gate and garage openers, and electronic door locks. Its design allows for batteryless transponder implementation with external components and features on-chip tunable RC oscillator and EEPROM.
The HCS410T/ST supports PWM or Manchester RF encoding and offers features like anti-collision for multiple transponders and passive proximity activation. The device is protected against reverse battery and includes intelligent damping for high Q LC-circuits.
