Infineon SLS37CSAUSVQFN32XTMA4

Infineon’s SLS37 V2X HSM safeguards automotive V2X (Vehicle to Everything) communication based on a tamper-resistant security controller tailored to the security needs in V2X applications within telematics control units, protecting critical assets such as the integrity and moreover authenticity of messages, as well as the privacy of the sender. This plug & play security solution offers a host of benefits to automotive OEMs, tier-1 suppliers, and software providers for the development of connected vehicles.In a V2X application the SLS37 serves as an HSM (hardware security module) for storing private keys and handling V2X security operations attributed to the most critical assets. This includes ECC private key management (generation, derivation, deletion), ECDSA signature generation, ECIES encryption and decryption, and storage of generic data.The hardware architecture is based on a 32-bit Arm® SecurCore® SC300 CPU with an additional high-performance cryptographic engine and a latest-generation hardware coprocessor for asymmetric cryptography. For communication to the host processor, the SLS37 uses an SPI interface with data protection.The robust, automotive-qualified hardware comes with preprogrammed firmware, both security-certified, complemented by Infineon’s V2X host library software package for seamless integration in various host application processors. Secured firmware updates with end-to-end protection make this solution future-proof as fixes can be added in the field.As a discrete HSM, the SLS37 is agnostic to existing or upcoming modem standards.

Symbol Views

(not all views will be available for every part)

Normal: Standard and most popular representation of schematic symbol

ALT_1 (IEEE view): Symbol representation in a way that is more graphical in explaining what the purpose of each pin is. For connectors and most discretes (as we use these views) it is simply an alternate view for people to use depending on the situation. For instance connectors can be generally an input, an output or neither. Resistors can be vertical or horizontal.

ALT_2 (demorgan): Demorgan is a name for an equivalent Gate structure. so for instance an AND gate and an OR gate can be represented by its Demorgan equivalent of a NOR gate.

Sometimes a device is fractured into multiple symbols (often for high pin count parts). If that is the case, you can preview the different symbols that make up the device by selecting them in this drop down.

Footprint Views

(not all views will be available for every part)

Basic: Our standard footprint view showing, contact area, pin number, top, top assembly

Detailed: Additional info to help you evaluate the part and the footprint including: dimension, silkscreen, soldermask, and solderpaste

PinDetail: Highlights the pin to pad contact area dimensions

Displays min/typ/max pad sizes for footprint per IPC specification (not all sizes will be available for every part)
