Frequently Asked Questions
What encryption method does the HCS201-I/SN use?
The HCS201-I/SN uses Microchip's proprietary KEELOQ code hopping algorithm, which generates a unique 32-bit encrypted rolling code with each button press. This prevents replay attacks by ensuring that captured transmissions cannot be reused to gain unauthorized access to secured systems.
What package does the HCS201-I/SN come in?
The HCS201-I/SN is housed in an 8-pin SOIC (Small Outline IC) package with a 0.150-inch body width, identified by JESD-30 code R-PDSO-G8. This compact surface-mount package is well-suited for small RF transmitter PCBs used in key fobs, security remotes, and wireless access control devices.
What are typical applications for the HCS201-I/SN?
Typical applications include automotive remote keyless entry (RKE) transmitters, garage door openers, security alarm remotes, and industrial wireless access control systems. The KEELOQ rolling code encryption built into the HCS201 makes it a standard encoder IC for any transmitter design requiring robust protection against code-grabbing and replay attacks.
Is the HCS201-I/SN RoHS compliant?
Yes, the HCS201-I/SN is RoHS compliant and lead-free as indicated by its Pbfree Code designation and JESD-609 e3 classification. This ensures the device meets modern environmental regulations for hazardous substance restrictions, making it suitable for use in consumer and automotive electronics products sold globally.
What is the lead time and availability for the HCS201-I/SN?
The HCS201-I/SN typically has a factory lead time of 6 weeks when ordered directly from Microchip Technology. Stock availability may vary by distributor, and buyers are encouraged to check with authorized distributors for immediate inventory levels and pricing to meet project timelines.
