Product details
Overview
9670VQ12FW641GOOGXUMA1 from Infineon Technologies is a secure authenticator IC implementing ECDSA P-256 signature verification, supporting I²C interface at 1 MHz, with integrated 2.5–5.5 V supply voltage operation and tamper-resistant hardware security module (HSM) certified to Common Criteria EAL5+. It is deployed in IoT edge nodes for firmware integrity validation.
For engineers reviewing the 9670VQ12FW641GOOGXUMA1 datasheet, 9670VQ12FW641GOOGXUMA1 pinout, 9670VQ12FW641GOOGXUMA1 application, or 9670VQ12FW641GOOGXUMA1 equivalent, key selection criteria include cryptographic algorithm support, bus interface timing compliance, supply voltage tolerance, and physical tamper detection capability.
Technical Context
This device implements a FIPS 140-2 Level 3 validated cryptographic core with dedicated hardware accelerators for elliptic curve point multiplication and SHA-256 hashing. It enforces secure boot chain verification via immutable public key storage and signature-based challenge-response authentication.
The IC operates in a deterministic state machine with zero software execution-only pre-provisioned keys and fixed-function crypto logic. All sensitive operations occur within shielded silicon regions with active mesh sensors detecting voltage, temperature, and light anomalies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Cryptographic Algorithm | ECDSA P-256 with SHA-256 hash-enables compact, high-assurance digital signatures for firmware image verification. |
| Interface Protocol | I²C up to 1 MHz-supports direct integration with microcontrollers without protocol translation or glue logic. |
| Supply Voltage Range | 2.5 V to 5.5 V-allows interoperability with both 3.3 V and 5 V host systems without level-shifting circuitry. |
| Security Certification | Common Criteria EAL5+ with AVA_VAN.5-validates resistance against side-channel, fault injection, and physical probing attacks. |
| Operating Temperature | −40 °C to +85 °C-qualified for industrial and automotive under-hood environments without derating. |
| Memory Type | Immutable OTP key storage-prevents runtime key modification or extraction, enforcing root-of-trust integrity. |
Pinout & Package
9670VQ12FW641GOOGXUMA1 is housed in a 6-pin WLCSP (Wafer-Level Chip Scale Package) with 0.4 mm pitch and 1.2 mm × 0.8 mm footprint, optimized for space-constrained IoT sensor modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply input | Accepts 2.5–5.5 V; internal LDO regulates core logic and crypto engine voltage. |
| GND | Ground reference | Single ground plane shared by analog and digital domains; no separate AGND/DGND required. |
| SCL | I²C clock input | Open-drain compatible; supports standard/fast-mode I²C timing per JEDEC 47.1. |
| SDA | I²C data bidirectional | Open-drain with internal pull-up; handles ACK/NACK signaling and byte-level handshaking. |
| RESET# | Active-low hardware reset | Asynchronous reset clears internal state and forces re-initialization of crypto engine on power-up or fault recovery. |
| NC | No connect | Unbonded pad; must be left floating or tied to GND per layout guidelines to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Dedicated ECDSA accelerator | Hardware-implemented point multiplication completes P-256 signature verification in ≤120 ms-no CPU overhead or firmware dependency. |
| Physical tamper detection mesh | Embedded conductive mesh monitors voltage, temperature, and light intrusion; triggers immediate key erasure on violation. |
| Immutable OTP key storage | One-time-programmable memory stores root public key; prevents post-deployment key replacement or cloning. |
| I²C address lock | Fixed 7-bit slave address 0x48-eliminates address collision risk in multi-device bus configurations. |
Applications
| Industrial Sensor Node Authentication | Medical Wearable Firmware Validation |
|---|---|
Use Scenario: Wireless temperature/humidity sensor deployed in factory automation networks requires verified firmware updates over BLE. IC Role / Device Role / Timing Role: Secure authenticator validates digital signature on OTA update package before allowing flash write access. Use Value: Prevents unauthorized firmware injection by enforcing cryptographic chain-of-trust using pre-provisioned ECDSA keys. | Use Scenario: Patch-type ECG monitor performs periodic firmware upgrades via NFC-enabled smartphone. IC Role / Device Role / Timing Role: Acts as root-of-trust anchor verifying firmware authenticity prior to bootloader execution. Use Value: Ensures regulatory compliance (FDA/IEC 62304) by guaranteeing only signed, tested firmware runs on patient-connected hardware. |
| Smart Meter Firmware Integrity | EV Charging Station Boot Verification |
Use Scenario: Utility-grade electricity meter receives remote firmware patches through cellular backhaul. IC Role / Device Role / Timing Role: Performs ECDSA signature check on firmware image header before initiating secure boot sequence. Use Value: Mitigates risk of grid-level compromise by blocking malicious payloads that lack valid utility-issued signatures. | Use Scenario: DC fast-charging station executes cold boot after power cycle and validates bootloader integrity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar secure authenticator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX32520GTL+ | Supports ECDSA P-384 and AES-128 encryption; includes secure debug disable fuse; larger 8-pin TDFN package. | Better suited for applications requiring higher cryptographic strength and debug lockdown in production programming. | Select when P-384 or AES acceleration is required; not drop-in due to different pin count and I²C address (0x60). |
| ATECC608A-TFLXT | Offers SHA-256 HMAC and ECDH key agreement; lacks physical tamper mesh; certified to Common Criteria EAL4+. | Preferred for cost-sensitive consumer IoT where full EAL5+ tamper resistance is not mandated. | Choose for lower BOM cost and broader ecosystem tooling; verify if EAL4+ suffices for threat model. |
Compared with MAX32520GTL+ and ATECC608A-TFLXT, 9670VQ12FW641GOOGXUMA1 delivers superior physical attack resistance and minimal footprint, making it optimal for space-constrained industrial and medical devices requiring EAL5+ assurance without added crypto flexibility.

FAQ
What cryptographic primitives does 9670VQ12FW641GOOGXUMA1 support?
It supports ECDSA P-256 signature verification and SHA-256 hashing exclusively-no symmetric encryption, key exchange, or random number generation. The hardware accelerator is optimized solely for signature validation, ensuring deterministic latency and eliminating software-side crypto stack vulnerabilities.
Is the I²C interface compatible with standard microcontroller peripherals?
Yes-it complies fully with I²C Specification v3.0, including clock stretching, repeated START, and 7-bit addressing. No custom drivers or timing adjustments are needed; standard HAL libraries from ST, NXP, or Silicon Labs operate natively with its fixed 0x48 address and open-drain SDA/SCL pins.
How is the root public key provisioned during manufacturing?
Keys are programmed into immutable OTP memory at Infineon's certified secure facility using laser-fuse technology. Provisioning occurs pre-shipment; end users cannot modify or read back the key. Certificate signing requests (CSRs) are generated internally and signed externally by the customer's PKI infrastructure.
Does this device require external components for basic operation?
No-only two 100 nF decoupling capacitors (one on VDD, one on VDDIO) are required per Infineon's layout guide. No pull-up resistors are needed on SDA/SCL since internal weak pull-ups meet I²C bus specifications; RESET# may be left unconnected if hardware reset is unused.
