Product details

Overview

SLS32AIA010MSUSON10XTMA2 from Infineon is a Common Criteria EAL 6+ certified security controller implementing I²C-based encrypted communication via Shielded Connection, supporting ECC up to P-521, RSA-2048, AES-256, SHA-256/512, and TLS v1.2 PRF/HKDF; it provides 10 kB user memory and hibernation with leakage current < 2.5 µA for secure boot and firmware authentication in edge IoT nodes.

For engineers reviewing the SLS32AIA010MSUSON10XTMA2 datasheet, SLS32AIA010MSUSON10XTMA2 pinout, SLS32AIA010MSUSON10XTMA2 application, or SLS32AIA010MSUSON10XTMA2 equivalent, key selection criteria include CC EAL 6+ hardware certification, I²C shielded interface compliance, hibernation power budget (<2.5 µA), monotonic counter count (4), and industrial lifetime (20 years).

Technical Context

The device implements a dedicated cryptographic coprocessor architecture with isolated execution environment, hardened against side-channel and fault injection attacks. It supports configurable security monitor policies and four monotonic counters for anti-rollback enforcement in firmware update workflows.

Its I²C interface operates in Standard (100 kbit/s), Fast (400 kbit/s), and Fast Mode Plus (1 Mbit/s) modes with programmable pull-up voltage (1.62–3.6 V) and supports encrypted command/response exchange using pre-shared keys or asymmetric session establishment.

Key Specifications

Parameter	Value and Actual Design Meaning
ECC Support	NIST P-521 and Brainpool r1 up to 512-bit - enables high-assurance key exchange and digital signatures compliant with FIPS 186-4 and BSI TR-03111.
RSA Support	Up to 2048-bit - sufficient for PKI-based certificate verification and legacy signature schemes in constrained devices.
AES Key Size	256-bit - provides confidentiality for symmetric encryption of sensitive data objects and secure channel establishment.
User Memory	10 kB - allocated for storing cryptographic keys, certificates, firmware metadata, and application-specific secrets with integrity protection.
Hibernate Leakage	< 2.5 µA - enables multi-year battery operation in always-on security modules without compromising tamper response latency.
Security Certification	Common Criteria EAL 6+ (high) and PSA Level 3 - validated hardware root of trust suitable for industrial automation and cloud-connected endpoints.
Operating Temperature	−40 °C to +105 °C - qualified for extended industrial environments including building control and infrastructure gateways.

Pinout & Package

Package: PG-USON-10-2,-4 (3 mm × 3 mm, 0.4 mm pitch, 10-terminal exposed pad). Compliant with JEDEC MO-229 and RoHS.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Power supply input	1.62–3.6 V operating range; decoupling capacitor required per datasheet Section 5.1.3.1.
GND	Ground reference	Connected to exposed thermal pad; mandatory for thermal dissipation and signal integrity.
SCL	I²C clock line	Open-drain, requires external pull-up; supports Standard/Fast/Fast Mode Plus timing per Table 8–10.
SDA	I²C data line	Open-drain, bidirectional; encrypted payload transmission enabled only after Shielded Connection handshake.
RESET_N	Active-low reset input	Asynchronous hard reset; initiates full state wipe and reinitialization of security monitor.
GPIO	General-purpose I/O	Configurable as hibernation control signal (drives external MOSFET gate per Figure 4–5) or status indicator.
NC	No connect	Terminal 7 and 9 are unconnected; must remain floating or tied to GND per marking pattern Table 5.

Key Features

Feature	Design Value
Shielded Connection protocol	End-to-end encrypted I²C session layer preventing eavesdropping and man-in-the-middle on bus traffic.
Hibernate mode	Zero-power retention of secure state with sub-2.5 µA leakage-enables persistent trust anchor without battery drain.
Monotonic counters	Four independent, non-resettable counters for enforcing firmware version roll-forward and detecting rollback attempts.
Protected object update	Atomic write with integrity and confidentiality guarantees for keys, certificates, and metadata-no partial overwrite exposure.
OPTIGA™ Trust M Software Framework	Open-source GitHub implementation (Infineon/optiga-trust-m) providing production-ready drivers and crypto tooling for Linux/RTOS.

Equivalent & Alternatives

The following parts are listed as comparable options for similar security controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SLB9670VQ2.0	TPM 2.0-compliant discrete TPM with SPI interface; no hibernation mode; 128 kB NV storage.	Targeted at x86/ARM server platforms requiring standardized TPM stack integration; lacks I²C shielded connection.	Select when TPM 2.0 compliance and OS-level TCG stack support are mandatory over ultra-low-power operation.
ATECC608B-TNGTLS	Elliptic Curve Crypto engine with TLS offload; no CC certification; 16 kB EEPROM; I²C only.	Optimized for TLS handshake acceleration in resource-constrained microcontrollers; lacks monotonic counters and hibernate.	Select when TLS v1.2 client-side offload is primary need and formal security certification is not required.

Compared with SLB9670VQ2.0 and ATECC608B-TNGTLS, SLS32AIA010MSUSON10XTMA2 uniquely combines CC EAL 6+ certification, hibernation <2.5 µA, and Shielded Connection-making it optimal for battery-operated, certifiable edge devices where both assurance level and power efficiency are non-negotiable.

FAQ

Does SLS32AIA010MSUSON10XTMA2 support TLS 1.3?

No. The device implements TLS v1.2 PRF and HKDF functions per its Crypto ToolBox specification, but does not natively support TLS 1.3 handshake or record layer processing. Integration with TLS 1.3 stacks requires host-side negotiation and key derivation delegation.

What is the maximum I²C clock frequency supported in Fast Mode Plus?

The device supports I²C Fast Mode Plus at up to 1 Mbit/s, as confirmed in Table 10 of the datasheet. This requires host-side Fast Mode Plus capability and appropriate bus capacitance control (≤ 500 pF) per Section 5.1.2.

Can monotonic counters be reset by any command or condition?

No. All four monotonic counters are non-resettable in normal operation. They increment only on explicit command (e.g., COUNTER_INCREMENT) and persist across power cycles and hibernation. Reset is physically impossible without destructive package analysis.

Is the 10 kB user memory organized as EEPROM or flash?

The 10 kB user memory is implemented as secure, wear-leveled non-volatile memory managed by the internal security controller. It is not user-accessible as raw EEPROM or flash; access occurs exclusively through protected object-oriented commands (e.g., DATA_OBJECT_WRITE) with integrity and confidentiality enforced.
