What are the key features of STSAFE-V110?
- Hardware-secured ECDSA-256 cryptographic engine provides root-of-trust for vehicle identity authentication and V2X communications
- Tamper-resistant secure element architecture protects private keys against side-channel and physical attacks in automotive-grade environments
- ISO/IEC 7816 and SPI interface options enable flexible integration with existing automotive ECU security processors
What is STSAFE-V110 used for?
STSAFE-V110 is designed for automotive cybersecurity applications including vehicle-to-everything (V2X) communication nodes, OTA firmware update authentication, and in-vehicle network security gateways requiring hardware root-of-trust. Its ECDSA-256 engine provides the cryptographic backbone for IEEE 1609.2 certificate handling in connected vehicle infrastructure. Charging station authentication, EV fleet management, and secure diagnostics ports also leverage the device's tamper-resistant key storage for ISO/SAE 21434 compliance.

Frequently Asked Questions
What cryptographic algorithms does STSAFE-V110 support for automotive V2X security operations?
STSAFE-V110 supports ECDSA-256 (Elliptic Curve Digital Signature Algorithm with 256-bit keys) and SHA-256 hash operations as its primary cryptographic functions. These algorithms align with IEEE 1609.2 and ETSI TS 103 097 V2X security standards, enabling vehicles to sign and verify safety messages at rates exceeding 1,000 signatures per second required for high-density V2X environments at urban intersections. The hardware acceleration completes a single ECDSA-256 sign operation in under 300 ms.
How does STSAFE-V110 protect stored private keys against physical and side-channel attacks?
STSAFE-V110 uses a tamper-resistant secure element architecture with active shield mesh, voltage and frequency glitch detection, and differential power analysis countermeasures embedded in silicon. Private keys are stored in isolated non-volatile memory cells that cannot be extracted through JTAG, SWD, or any external interface—any tamper attempt triggers an automatic key zeroization response within 1 µs. This design meets Common Criteria EAL4+ evaluation assurance level requirements for hardware security modules.
What interface does STSAFE-V110 use to connect to an automotive ECU host processor?
STSAFE-V110 supports both ISO/IEC 7816 (single-wire half-duplex) and SPI interfaces, allowing designers to choose based on existing ECU bus topology. SPI operation at up to 2 MHz enables fast certificate transfer in latency-sensitive V2X applications. The device operates from a 2.7 V to 3.6 V supply and is rated for the automotive temperature range of -40°C to +105°C, conforming to AEC-Q100 Grade 2 requirements for passenger car ECU integration.
In what physical package does STSAFE-V110 ship and how does it fit into compact automotive module designs?
STSAFE-V110 is available in a small outline IC package measuring approximately 4.9 mm x 3.9 mm with 8 leads at 1.27 mm pitch. This compact SO-8 footprint occupies less than 20 mm² of PCB area, enabling direct integration onto telematics control unit (TCU) boards alongside the main application processor without requiring a separate security daughter card. The surface-mount package is compatible with standard automotive reflow profiles at 260°C peak temperature.
