HCS300-I/P Description

Short technical summary and product information.

The HCS300-I/P from Microchip Technology is a specialized integrated circuit designed for secure Remote Keyless Entry (RKE) applications. It utilizes KEELOQ® code hopping technology to ensure each transmission is unique, preventing code scanning and capture.

 

This encoder operates within a voltage range of 2.0V to 6.3V and features a 66-bit transmission code length, incorporating a 32-bit hopping code, a 28-bit serial number, and status bits. The device includes an on-chip EEPROM for storing cryptographic keys and serial numbers, which are read-protected for enhanced security.

 

The HCS300-I/P is supplied in an 8-DIP (Dual In-line Package) with through-hole mounting. Its typical applications include automotive RKE systems, alarm systems, immobilizers, and gate or garage door openers. The integrated design requires minimal external circuitry, making it a cost-effective solution for unidirectional remote keyless entry and access control systems.
