HCS300T-I/SN Description

Short technical summary and product information.

The HCS300T-I/SN from Microchip Technology Inc. is a code hopping encoder utilizing KEELOQ® technology for secure Remote Keyless Entry (RKE) systems. This device offers a 66-bit transmission code length, combining a 32-bit hopping code with a 28-bit serial number and information bits to prevent code scanning and capture.

 

Key features include a wide operating voltage range of 2.0V to 6.3V, four button inputs, and 15 available functions. The encoder has a programmable 64-bit encryption key and a programmable 28-bit serial number. Cryptographic keys are read-protected for enhanced security. The HCS300T-I/SN is housed in an 8-SOIC package suitable for surface mounting.

 

Typical applications for the HCS300T-I/SN include automotive RKE systems, alarm systems, immobilizers, gate and garage door openers, and identity tokens. Its design incorporates an on-chip EEPROM, oscillator, and timing components, with internal pull-down resistors on button inputs and current limiting on the LED output, minimizing external circuitry requirements.
