Automotive-grade FPGAs & SoCs
The new benchmark for security and reliability in automotive
The automotive industry is using increasingly complex electronic systems to offer better security and efficiency to the driver. These systems not only need to meet market requirements but also need to ensure defect-free and fail-safe operation throughout the life of the car. To ensure that applications work with zero failures, all components involved in the design must meet or exceed reliability qualification set by various industry bodies like the Automotive Electronic Council (AEC). In addition to this, the applications must be secure from any kind of tamper, corruption or unauthorized access. Any unauthorized or accidental change to the functionality of the system can be catastrophic and lead to loss of life.

Advanced Driver Assist Systems (ADAS) are a category of electronic systems which provide passive and active feedback to improve safety and comfort while driving a car. They are predictive systems which provide early warnings of potential dangers with the aim of preventing accidents. These systems are seeing increased adoption by OEMs due to increase in awareness of consumer safety and Government legislations. Various features of ADAS include adaptive cruise control, blind-spot warning, lane-departure warning, collision avoidance and pedestrian detection systems.
Microsemi FPGAs offer differentiation to OEMs and suppliers by providing a secure implementation of ADAS systems.
ADAS system architecture
ADAS solutions from Microsemi work on a complex system of sensors to relay information like speed, temperature, object, signal and lane detection to the processing and control unit. These inputs are processed for image enhancement, distortion correction, object identification, motion estimation and further, analysed to take corrective actions.
The control system takes processed inputs and controls outputs i.e. braking, giving driver alerts etc. An ADAS must adhere to its functionality to prevent accidents and hence needs a secure and fail safe system implementation.
Benefits of Microsemi FPGAs in ADAS
Microsemi FPGAs provide core data acquisition, processing and display functions while providing industry’s best reliability and security in small footprint packages crucial for building differentiated, secure and reliable advanced driver assist systems.
- Data processing and display – Support for various communications interfaces for capturing data like camera, radar - available as hard or soft IPs. FPGAs offer a crucial advantage over DSPs in providing parallel processing, enabling faster responses to potential hazards.
- Zero defect systems – Offer immunity against environment factors leading to single event upset. SEU immunity is paramount in achieving ZERO FIT rate and insurance against potential application failure.
- Tamper-free applications – Protection of data and customer’s “secret sauce” from tamper and malicious intent.
- Low power consumption – Comparable or lower power consumption to comparable ASSP based solutions for complex processing in multi-input and output interfaces system.
- More resources in a smaller footprint - No external configuration memory required providing a real-estate advantage in space constrained applications. Allows for more features to be integrated onto a single device.
Vehicle-to-vehicle (V2V) or vehicle-to-infrastructure (V2I) communications jointly called as V2X are expected to have a bigger impact on road safety by being able to perceive danger sooner and warn drivers of potential hazards. V2X communications use onboard dedicated short-range radio communication devices to transmit information about the vehicle like speed, heading, brake status etc to other vehicles and receive the same information. Communication must be secure if vehicle connectivity is to be used safely and with confidence.
With the adoption of vehicle connectivity applications, the number of vehicles and sources talking to each other will increase exponentially and nearly on all this traffic is vulnerable to malicious monitoring and modification.
Microsemi offers best-in-class security for vehicle-to-vehicle and vehicle-to-infrastructure communication. Among the available security services, Microsemi offers the most effective authentication feature when a SRAM based physically unclonable function (PUF) is used to compute the private key for identifying a device. Also critical is the use of a public key infrastructure (PKI) for distributing and ensuring associated public keys are authentic.
Microsemi PKI Infrastructure
Public key cryptography employs a private key that the sender uses to digitally sign outgoing messages and is known only to that source. Verifying the digital signature using the sender’s associated public key ensures message authenticity.
Microsemi PKI architecture
The private key is computed from a PUF, which is based on a physical characteristic that is created during a device’s manufacture. This characteristic is unique to each copy of the device due to small (often atomic scale), uncontrollable (and therefore impossible to clone) and yet measurable random manufacturing variations. Their measurements are analogous to a fingerprint (‘biometric signature’) and can be used to construct a private key specific to that particular device.
In addition to using asymmetric authentication with PUF-based private keys, a PKI should be used to distribute and ensure that the associated public keys are authentic. In a PKI, a certificate authority (CA) certifies all the approved devices that belong to the network by digitally signing their public keys using the CA’s own private key. In the case of SmartFusion2 and IGLOO2; Microsemi can act as the certificate authority if needed.
Benefits of Microsemi FPGAs in Vehicle Connectivity
Microsemi offers a secure communication infrastructure for vehicle connectivity. With Microsemi’s advanced data and design security features, messaging between two sources is protected against tamper and corruption. Secure hardware using the device’s PUF forms the basis of the root-of-trust. Secure communications involve multiple key authentications from simultaneous and serial interactions. Microsemi offers a dedicated hardware processing engine for faster and reliable key authentication offloading the system controller.

Rise in fuel prices, recent legislations on emissions and customer demands of better performance and quality are propelling the automotive industry to emerge with solutions that offer better alternatives to the internal combustion engine.
Electrification of the powertrain is emerging as a top trend with a variety of options offered to the customers – hybrid, plug-in hybrid, fully electric. Automotive electronics play an important role in this context of electrification leading to new and complex configurations of the engine control unit. Hybrid/electric engine control units pose some challenges to the designers in terms of
- Integration of various components
