Microchip HCS301-I/SN is a 4-input code hopping encoder featuring a compact 8-pin SOIC surface mount package. This device is designed primarily for wireless remote control systems requiring secure transmission such as automotive remote keyless entry (RKE), alarm systems, immobilizers, and gate or garage door openers.
Constructed within the HCS logic family series, this encoder enables transmission of encrypted codes using KeeLoq technology, which enhances security by preventing replay attacks and unauthorized access. It operates over a voltage range from 3.5 V to 13 V and withstands a wide temperature range of -40°C to 85°C, making it suitable for automotive and industrial environments.
The device measures 4.9 mm in length and 1.5 mm in height, fitting efficiently onto printed circuit boards with a surface mount (SOIC) design optimized for high-volume automated manufacturing processes. The 8-pin configuration offers 4 input channels for multiple button or signal inputs.
Applications include secure remote control for automotive systems, burglar alarms, identity tokens, and other wireless access control systems. While this model does not carry special automotive certification, its robust design meets the general requirements for electronic components in vehicle and industrial control systems.
Features 4 input pins for flexible encoding options. Utilizes code hopping technology for enhanced security in wireless systems. Operates with a minimum supply voltage of 3.5V and maximum of 13V. Designed for operation within a temperature range of -40°C to 85°C.
Compact dimensions with a length of 4.9mm and height of 1.5mm ensure minimal PCB footprint. Compatible with automotive remote keyless entry and alarm system applications. Available in surface mount SOIC package optimized for automated assembly.
Does not incorporate any mandatory automotive standards or certifications. Ideal for security in gate and garage door openers with KeeLoq encoding.
This Microchip HCS301-I/SN encoder is an essential component for manufacturing secure industrial and automotive remote control equipment. Browse EnvMart's Semiconductor category for more advanced electronic components and encoding IC options to suit your application needs.
