HCS410/SN from Microchip Technology is a KEELOQ rolling-code encoder with bidirectional transponder capability for secure access-control credentials in tube-packed SOIC-8.
Specifications were checked against the manufacturer data sheet and current distributor listing.
HCS410 combines KEELOQ code-hopping transmission with transponder operation for secure remote and proximity access-control systems.
Rolling-code authentication resists simple captured-code replay.
Encoder and transponder modes support remote and close-range credential use in one device.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Code-hopping encoder and transponder
Button/encoder inputs, serial transmit output and transponder communication interface
Access-control applications; programmable secure credentials; SOIC-8
8-SOIC (0.154", 3.90mm Width)
This ordering code uses the 8-SOIC (0.154", 3.90mm Width) package.

Confirm exact numbering and the latest land pattern before PCB release.
