Microchip Technology HCS410T-I/SN

The HCS410 combines code-hopping remote-control encoding with a batteryless, bidirectional low-frequency transponder interface. A 69-bit encoder transmission has a 32-bit encrypted hopping portion and a 37-bit fixed portion. Challenge-response operation uses a programmed encryption key. The T in this exact order code identifies tape-and-reel supply; it is not a separate electrical function.

Microchip identifies SN as an 8-lead plastic SOIC with a nominal 150 mil body. I denotes −40 to +85 °C, and HCS410T denotes tape-and-reel ordering. The site's registered 8-SOIC package matches the catalog's 0.154-inch width designation. Confirm the manufacturer's drawing and pin-1 orientation before PCB release.

Layout checks

• Use the SOIC top-view pin diagram for orientation.
• Design the LC0/LC1 network to the intended transponder mode.
• Check VDD decoupling and external transmitter connections.

The registered package and local JPG were checked. This illustration is not a dimensional drawing.

Confirm multiplexed behavior against the selected operating configuration.

Electrical and protocol details depend on configuration and the external system.

HCS410-I/SN is the corresponding non-T ordering form listed separately in the product database, but verify reel presentation and procurement requirements before changing the exact order code. Other HCS parts are not automatically interchangeable: compare pinout, transponder network, key and seed provisioning, protocol, package, and temperature grade. No internal alternative is linked without record-level verification.

Microchip Technology's HCS410 datasheet DS40158F describes operation, pin configuration, electrical limits, and the product identification system. Its ordering table explicitly identifies HCS410T as tape-and-reel, I as −40 to +85 °C, and SN as the 8-lead plastic SOIC.

Check the complete HCS410T-I/SN order code, SOIC package, reel labeling, and lot traceability. Ensure encryption keys, serial identity, seed, and configuration are programmed through an authorized process and validated with the intended receiver and reader.

Protect keys during manufacturing and validate receiver synchronization, LF coil tuning, challenge-response configuration, switch behavior, output timing, and supply limits against DS40158F. Verify the complete RF and transponder links before deployment.
