Product Details
TA010-SSYDAB-VAO - Automotive Authentication IC
TA010-SSYDAB-VAO is Microchip's CryptoAutomotive secure authentication device with an I2C interface, 8-lead SOIC package and bulk tube ordering option. Its protected ECC and symmetric-key resources support automotive component identity and anti-counterfeit designs.
Based on Microchip TA010 CryptoAutomotive Summary Data Sheet DS40002440C and the current TA010 product page.
Overview
The exact TA010-SSYDAB-VAO ordering code selects an automotive-temperature SOIC-8 part using a standard I2C interface up to 400 kHz. It is intended for cost-sensitive hardware authentication, such as verifying an EV battery module or an authorized component. The host and device must be provisioned and integrated to the chosen identity or challenge-response policy; the chip does not establish application security by itself.
Key Advantages
Hardware key storage reduces exposure of authentication secrets to host software.
SDA and SCL connect to a Standard or Fast mode host bus.
The Y ordering option specifies -40°C to +125°C ambient operation.
Each device has a unique 72-bit serial number for identity workflows.
Feature Summary
A protected private key supports asymmetric authentication operations.
Storage supports a device certificate and a CA signer certificate.
Protected symmetric-key and HMAC functions support challenge-response protocols.
Includes a monotonic counter and 64 bytes of user memory subject to configuration.
Package & Footprint
The database registers 8-SOIC (0.154", 3.90mm Width). Microchip's SS suffix denotes an 8-lead narrow-body SOIC; use the manufacturer's current mechanical drawing to confirm body dimensions, pin-1 marking and PCB land pattern. The local JPG is a generic package illustration, not a photograph of the actual device.
- Confirm pin-1 index and current Microchip footprint.
- Provide VCC decoupling and I2C bus pull-up resistors as required.
- Do not copy single-wire wiring from the CZ-suffix variant.
Pin Functions
For the manufacturer's 8-lead SOIC I2C variant, pins 1-3 and 7 are NC, pin 4 is GND, pin 5 is SDA, pin 6 is SCL and pin 8 is VCC. Provide SDA/SCL pull-ups sized for the board and the selected I2C clock rate.

Operating and current figures depend on interface mode, VCC, temperature and measurement conditions; consult the full electrical tables.
Replacement Considerations
TA010-SSYCZT-VAO uses a PWM single-wire interface; pin 6 is NC instead of SCL. It is not a direct host-interface replacement for this DA I2C version. Compare provisioned keys, certificates, host code, pull-up design and package before any substitution. No unverified internal product link is included.
Manufacturer Information
Microchip's TA010 CryptoAutomotive Summary Data Sheet DS40002440C explicitly lists TA010-SSYDAB-VAO as an 8-lead SOIC, automotive-temperature, I2C, bulk tube ordering code. It also documents security resources, I2C pin functions, electrical characteristics and mechanical drawings. Use the latest Microchip revision for design release.
Applications
Authenticate a battery module to its host system.
Verify approved automotive accessories and replaceable components.
Bind a component identity to protected cryptographic credentials.
Use a protected counter where the provisioned policy permits.
Quality & Authenticity
Verify the full SSYDAB suffix, package marking, lot traceability and configured key or certificate records. The generic package image cannot authenticate a physical device. Test real challenge-response behavior with the intended host and trust anchor.
FAQ
Does this exact code use I2C?
Yes. DA selects I2C; CZ ordering codes select single-wire.
What is pin 6 in this version?
It is the SCL clock input in the SOIC I2C pinout.
Is it ready for any host without provisioning?
No. Confirm the actual key, certificate and access policy against the host implementation.
Does the image show device markings?
No; it shows a generic SOIC package.
Engineering Notice
Review the latest Microchip data sheet, errata and package drawing before design release. Validate I2C timing, pull-up sizing, supply and signal levels, credential lifecycle and the complete system threat model.
