TA010-SSYDAT-VAO

Overview

The TA010-SSYDAT-VAO is a CryptoAutomotive™ cryptographic authentication device designed for electric vehicle battery authentication and ecosystem control. It features secure hardware-based key storage, supporting ECDSA P-256 signatures, SHA-256, and HMAC. The device includes an internal TRNG compliant with NIST SP 800-90A/B/C standards and offers field-programmable EEPROM for keys and certificates. It operates within an automotive Grade 1 temperature range of -40°C to +125°C and supports I2C (400 kHz) or Single-Wire Interface (SWI) protocols.

Feature Summary

• Hardware-accelerated ECDSA P-256 signature generation and internal private key generation
• NIST-certified True Random Number Generator (TRNG) compliant with SP 800-90A/B/C
• Field-programmable EEPROM storing ECC private keys, certificates, and symmetric keys with >40-year retention
• Supports FIPS 140-3 Compliance Mode configuration via a dedicated configuration bit

Applications

• Electric Vehicle (EV) Battery Authentication
• Ecosystem Control through Asymmetric Authentication / PKI
• Anti-Counterfeiting Validation for OEM Components

Procurement Notes

Verify the specific ordering suffix against Microchip's Trust Platform variants (TrustFLEX/TrustCUSTOM). Confirm interface requirements (I2C vs. SWI) and package type (SOIC vs. VDFN) match the design specifications. Ensure compliance with AEC-Q100 Grade 1 qualification standards for the target automotive environment.

Selection Notes

Select this component for applications requiring high-security asymmetric authentication in automotive environments. Choose based on interface preference: I2C for standard multi-wire systems or SWI for reduced pin count and potential parasitic power operation. Verify that the required memory slots for keys and certificates fit within the available EEPROM space.

Part Context

The TA010 belongs to the Microchip CryptoAutomotive™ family, specifically engineered for high-security cryptographic tasks in automotive networks. It serves as a companion device to microcontrollers, offloading sensitive operations like key storage and signature generation to prevent software-level key exposure.

FAQ

What cryptographic algorithms does the TA010 support?

The TA010 supports ECDSA (FIPS186-4) with NIST P-256 curve, SHA-256, and HMAC/SHA-256.

Does the TA010 support parasitic power mode?

Yes, when using the Single-Wire Interface (SWI), the TA010 can operate in parasitic power mode with an external capacitor, reducing the pin count to two.

What is the maximum count value for the monotonic counter?

The TA010 features a monotonic counter with a maximum count value of 10,000.
