Automotive
Automotive electronics are evolving rapidly as vehicles become increasingly intelligent, connected, and electrified. From ADAS and autonomous driving to infotainment and power management, modern cars require advanced semiconductors to ensure safety, performance, and efficiency. In this shift, embedded memory and security IP play a critical role in enabling reliable and secure automotive systems.
Technologies
In the age of smart mobility, automotive-grade ICs must meet rigorous standards for safety, reliability, and long product lifecycles. The following technologies are essential to address these demands:
- OTP/MTP for sensor calibration and configuration
- PUF-based hardware security to achieve automotive safety (EVITA, ISO 26262)
Embedded Memory for Calibration and Configuration
Automotive systems often rely on analog and mixed-signal ICs for sensing and control. These ICs need to store trimming, calibration, and configuration data that fine-tune performance based on individual device characteristics or environmental conditions. Non-volatile memory such as OTP or MTP provides a secure and cost-effective way to permanently store this data even under extreme temperatures and voltage conditions. From image sensors in ADAS to battery management systems (BMS), embedded memory enables precision and long-term stability.
Secure Identity & Authentication
Modern vehicles are connected to external networks—cloud services, roadside units, or mobile apps—which raises serious security concerns. OTP and PUF technologies can be used to embed unique hardware identity and cryptographic keys directly onto the chip. These keys are essential for secure boot, encrypted communication, and over-the-air updates, ensuring only trusted code and entities are allowed access.
Functional Safety & Redundancy
Safety-critical systems such as braking, steering, and powertrain control must adhere to functional safety standards like ISO 26262. Embedded memories like OTP are used to store safety diagnostic parameters, fallback settings, and redundancy configurations. PUF-based solutions further enhance safety by offering tamper-proof, silicon-level protection against cyber-physical attacks.
