Frequently Asked Questions
What security technology does the HCS512/SO use?
The HCS512/SO uses Microchip's KeeLoq code hopping encryption algorithm, which generates a new encrypted rolling code with every transmission. This prevents replay attacks where an attacker records and re-transmits the signal to gain unauthorized access.
What package is the HCS512/SO available in?
The HCS512/SO is housed in an 18-pin SOIC (Small Outline Integrated Circuit) package with a 0.4-inch body width, corresponding to the JESD-30 code R-PDSO-G18. This standard surface-mount package is compatible with high-volume automated assembly.
What are the typical applications for the HCS512/SO?
This device is primarily used in automotive remote keyless entry systems, garage door openers, gate openers, building access control transmitters, and industrial wireless remote controls where secure, authenticated one-way communication is required.
What is the lead time and availability of the HCS512/SO?
The HCS512/SO has a factory lead time of approximately 6 weeks. It is available from authorized Microchip distributors worldwide. Check with distributors for current stock levels and pricing, as availability may vary by region.
