The Microchip Technology HCS410-I/ST is a specialized integrated circuit designed for secure entry systems, utilizing the KEELOQ® code hopping system. This device offers robust security features including two programmable 64-bit encoder keys and bi-directional challenge-and-response capabilities.
Key operating specifications include a wide voltage range of 2.0V to 6.6V, with specific support for 13V encoder-only operation. The IC features a 37-bit non-encrypted portion containing serial number, function code, battery low indicator, CRC, and queue information. It also includes an on-chip tunable RC oscillator with ±10% tolerance and on-chip EEPROM for storing configuration and security data.
The HCS410-I/ST is housed in an 8-TSSOP package, suitable for surface mount applications. Its compact dimensions (4.4mm width, 3mm length, 1mm height) make it ideal for space-constrained designs. Typical applications include automotive remote entry systems, alarm systems, immobilizers, gate and garage openers, and electronic door locks.
Additional features enhance its functionality and ease of use, such as selectable baud rates, automatic code word completion, battery low signal transmission, and non-volatile synchronization. The device is also protected against reverse battery connection and supports anti-collision for multiple transponders.
