HCS300T/SN Description

Short technical summary and product information.

The HCS300T/SN from Microchip Technology is a secure code hopping encoder utilizing KEELOQ® technology. It is designed for unidirectional remote keyless entry and access control systems, offering high security with a small package outline and low cost.

 

Key features include a programmable 28-bit serial number, a 64-bit encryption key, and a 66-bit transmission code length. Each transmission is unique, preventing code scanning and capture. The device operates from 2.0V to 6.3V and includes four button inputs, 15 available functions, and selectable baud rates. It also provides automatic code word completion and a low battery signal.

 

This encoder integrates an on-chip EEPROM for storing cryptographic keys, serial numbers, and configuration data, which is read-protected for enhanced security. It also features an on-chip oscillator and timing components, internal pull-down resistors on button inputs, and current limiting on the LED output. The HCS300T/SN is ideal for automotive RKE systems, alarm systems, immobilizers, and gate/garage door openers.

 

The HCS300T/SN is supplied in an 8-SOIC surface mount package. Its design minimizes the need for additional circuitry, reducing external component costs and simplifying implementation.
