Frequently Asked Questions
What security algorithm does HCS410-I/SN implement and how does it prevent replay attacks?
HCS410-I/SN implements the KEELOQ rolling code algorithm, generating a unique 32-bit encrypted hop code on every transmission. Since each code is used only once and valid only in a specific sequence window, captured codes cannot be replayed to gain unauthorized access, making it suitable for automotive key fobs and secure access transmitters.
What supply voltage range does HCS410-I/SN support for battery-powered key fob designs?
HCS410-I/SN operates over a supply voltage range of 2.0 V to 6.3 V, enabling use with standard 3 V coin cells or 6 V batteries commonly found in automotive key fobs and remote control transmitters. This wide range ensures reliable operation as the battery discharges over its service life.
How does the 8-pin SOIC package of HCS410-I/SN fit within compact key fob PCB layouts?
The 8-pin SOIC package with a 0.150 inch body width and SOP8 footprint occupies minimal board space, typically under 5 mm x 4 mm, making it straightforward to integrate on the small PCBs inside automotive key fobs, wireless door openers, and portable access control transmitters.
