Product details
Overview
SLB9655VQ12GOOGXUMA1 from Infineon Technologies is a discrete Trusted Platform Module (TPM) 2.0 security IC compliant with ISO/IEC 11889, supporting I²C host interface, 32-pin VQFN package, 3.3 V supply, and FIPS 140-2 Level 3 validated cryptographic operations for secure boot and attestation in server motherboards.
For engineers reviewing the SLB9655VQ12GOOGXUMA1 datasheet, SLB9655VQ12GOOGXUMA1 pinout, SLB9655VQ12GOOGXUMA1 application, or SLB9655VQ12GOOGXUMA1 equivalent, key selection criteria include TPM 2.0 compliance level, I²C timing support (up to 1 MHz), tamper-evident packaging, certified RNG output rate (≥10 Mbps), and firmware update capability via secure channel.
Technical Context
The SLB9655VQ12GOOGXUMA1 implements a dedicated ARM SecurCore SC300 CPU with on-die SRAM and flash, executing TPM 2.0 stack in ROM-resident firmware. It integrates a hardware-accelerated SHA-256/384 engine, RSA-2048/3072 and ECC NIST P-256/P-384 crypto engines, and a true random number generator meeting AIS-31 Class PTG.2 requirements.
It supports TPM command transmission over I²C at standard/fast/fast-plus modes (100 kHz / 400 kHz / 1 MHz), includes physical tamper detection via mesh sensor and voltage/temperature monitors, and enforces secure firmware updates using ECDSA-signed images verified against immutable root-of-trust keys.

Equivalent & Alternatives
The following parts are listed as comparable options for similar TPM 2.0 security applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST33TPHF2ESAB4 | ARM Cortex-M0+ core, SPI-only interface, no I²C support, lower max clock (400 kHz) | Requires SPI host redesign; lacks I²C fast-plus mode and integrated CLK input | Select when SPI-native platform exists and 1 MHz timing not required |
| ATTPM20-MA1 | Discrete TPM with SPI/I²C dual interface, but only FIPS 140-2 Level 2 certified, no physical tamper mesh | Acceptable for non-mission-critical endpoints where full Level 3 tamper resistance is not mandated | Choose for cost-sensitive industrial gateways needing basic TPM 2.0 compliance without Level 3 validation |
Compared with ST33TPHF2ESAB4 and ATTPM20-MA1, SLB9655VQ12GOOGXUMA1 uniquely delivers I²C fast-plus timing, FIPS 140-2 Level 3 readiness, and integrated tamper mesh - critical for server-grade root-of-trust where physical attack surface must be actively monitored and zeroized.

FAQ
What is the maximum I²C clock frequency supported by SLB9655VQ12GOOGXUMA1?
The SLB9655VQ12GOOGXUMA1 supports I²C Fast-Plus mode up to 1 MHz, enabling low-latency TPM command/response cycles essential for UEFI boot measurement sequences. This exceeds standard Fast-mode (400 kHz) and allows tighter timing margins in high-throughput server platforms.
Does SLB9655VQ12GOOGXUMA1 include a built-in real-time clock (RTC)?
No, SLB9655VQ12GOOGXUMA1 does not integrate an RTC. It supports optional external 32.768 kHz crystal or oscillator input on the CLK pin for timekeeping functions, but time stamping relies on host-provided timestamps or external RTC synchronization via TPM commands.
How is firmware updated securely on SLB9655VQ12GOOGXUMA1?
Firmware updates require ECDSA-signed images verified against immutable root keys stored in one-time-programmable (OTP) memory. The update process enforces signature validation, image integrity hashing, and rollback protection before committing to flash, preventing unauthorized or corrupted firmware installation.
Is SLB9655VQ12GOOGXUMA1 qualified for automotive applications?
SLB9655VQ12GOOGXUMA1 is AEC-Q100 Grade 3 qualified (−40 °C to +85 °C), making it suitable for under-hood automotive applications such as ADAS domain controllers. Its FIPS 140-2 Level 3 readiness and tamper detection align with ISO/SAE 21434 cybersecurity requirements for ASIL-B systems.
