Product Details
HCS300T-I/SN - KEELOQ Code Hopping Encoder, 8-Pin SOIC
HCS300T-I/SN from Microchip Technology is a KEELOQ code-hopping encoder for unidirectional secure remote keyless entry, in industrial-temperature 8-pin SOIC tape-and-reel packaging.
Specifications were checked against the manufacturer data sheet; distributor stock and prices require live confirmation.
Overview
HCS300 forms a 66-bit transmission code from a changing 32-bit hopping portion, 28-bit serial number and status information. A 64-bit encryption key and synchronization data reside in on-chip EEPROM. The T-I/SN code specifies tape and reel, industrial -40 C to +85 C rating and 150-mil 8-pin SOIC.
Key Advantages
A changing hopping code reduces simple capture-and-replay exposure.
Four switch inputs and an integrated LED driver simplify transmitter circuitry.
Supplied in the documented tape-and-reel surface-mount package.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary

Replacement Considerations
HCS300-I/SN is a verified catalog entry. The same HCS300 industrial SOIC device in standard non-reel ordering. Check procurement packaging and programmed key configuration; a receiver change is not implied by the carrier change.
Similarity of family name or package does not establish drop-in compatibility.
Manufacturer Information
Microchip DS21137G specifies the HCS300 pinout and HCS300T-I/SN order-code fields. Security provisioning and receiver learning must follow the controlled system design.
Applications
Encodes a button-driven transmitter for a compatible receiver.
Supports code hopping in gate or garage-door transmitters.
Quality & Authenticity
Match the complete ordering code, package marking and reel or lot label to authorized-channel records. Inspect moisture handling and solderability requirements before assembly.
FAQ
What is the main function?
KEELOQ code hopping encoder
What package is used?
