HCS320-I/P Description

Short technical summary and product information.

The Microchip Technology HCS320-I/P is a specialized integrated circuit designed for secure Remote Keyless Entry (RKE) applications. It utilizes code hopping technology to provide high security for unidirectional remote keyless entry and access control systems.

 

This encoder IC features a programmable 28-bit serial number and a programmable 64-bit encryption key, ensuring each transmission is unique with a 66-bit transmission code length. It supports a 32-bit hopping code and a 34-bit fixed code, comprising the serial number, function code, and status bits. The encryption keys are read-protected for enhanced security.

 

Operating within a voltage range of 3.5V to 13.0V, the HCS320-I/P offers 16 selectable functions and a selectable baud rate. It includes features like automatic code word completion, a battery low signal transmission, and on-chip EEPROM for non-volatile synchronization data. The device is housed in an 8-PDIP package and is designed for through-hole mounting.

 

Typical applications for the HCS320-I/P include automotive RKE systems, alarm systems, immobilizers, gate and garage door openers, and identity tokens. Its combination of high security, small package, and low cost makes it a suitable solution for various access control needs.
