SIC614A: High-Security Replacement for ID4A Transponder

Why Replace the ID4A Immobilizer Transponder?

If you’re looking for a reliable ID4A replacement, the SIC614A is the ideal solution for your next-generation vehicle immobilizer system. Designed as a direct replacement for the ID4A transponder family, the SIC614A slots into your existing design with no compromise on compatibility, while delivering significantly more memory capacity for your application needs. Our high-performance transponder uses low-frequency FDX technology at a 125 kHz field frequency, specifically engineered for vehicle immobilization applications that demand the highest levels of reliability and protection.

Why Choose the SIC614A Immobilizer Transponder?

Key Features:

• Built-in HT AES crypto algorithm (128-bit secret key) for fast mutual authentication.
  The integrated HT AES cryptographic engine utilizes a 128-bit secret key to perform fast and secure mutual authentication between the vehicle and the transponder. This advanced security mechanism ensures that only authorized keys are able to start the vehicle. Protecting against cloning and unauthorized access.
• Best-in-class read and write sensitivity.
  The SIC614A delivers outstanding read and write sensitivity, enabling reliable communication even in challenging environments where signal strength may vary due to surrounding materials.
• Qualified to AEC-Q100 Grade 3 for maximum automotive reliability.
  Meets stringent automotive testing standards, ensuring consistent performance across a wide range of operating temperatures and conditions.
• 3,584 bits of extended user memory with 20 years of non-volatile data retention. It providing the space to support additional integrated applications.
  With 3,584 bits of user memory and 20 years of non-volatile data retention, the SIC614A offers significantly more storage capacity than conventional immobilizer transponders. The expanded memory opens the door to storing vehicle-specific data, enabling more advanced and flexible system designs.
