Infineon Technologies SLS32AIA010MKUSON10XTMA3

Overview

SLS32AIA010MKUSON10XTMA3 from Infineon is a Common Criteria EAL 6+ and PSA Level 3 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 device authentication in IoT edge nodes.

For engineers reviewing the SLS32AIA010MKUSON10XTMA3 datasheet, SLS32AIA010MKUSON10XTMA3 pinout, SLS32AIA010MKUSON10XTMA3 application, or SLS32AIA010MKUSON10XTMA3 equivalent, this page delivers verified package mapping (PG-USON-10-2,-4), confirmed cryptographic capabilities, hibernation power behavior, I²C interface timing compliance (Fast Mode Plus), and real-world integration constraints including shielded bus routing and monotonic counter usage.

Technical Context

The device integrates a tamper-resistant secure element with dedicated cryptographic accelerators for asymmetric (ECC, RSA), symmetric (AES), and hashing (SHA-256/512, HMAC) operations, all executed within a hardware-isolated execution environment. Its I²C interface supports standard, fast, and fast mode plus speeds (up to 1 MHz), with mandatory shielded connection for encrypted command/response framing.

Security monitoring includes four monotonic up-counters and configurable event-triggered policies for fault injection, voltage glitching, or clock manipulation detection. Hibernate mode disables all internal clocks and logic while retaining SRAM state integrity, enabling zero-power secure storage between authenticated sessions.

FAQ

Does SLS32AIA010MKUSON10XTMA3 support TLS 1.3?

No. The device implements TLS v1.2 PRF and HKDF functions up to SHA-512, but does not include native TLS 1.3 handshake acceleration or key schedule support. Integration with TLS 1.3 stacks requires host-side negotiation and key derivation, using OPTIGA™ Trust M for private key operations only.

Can the 10 kB user memory be partitioned into multiple secure objects?

Yes. Memory is organized into protected objects with configurable access policies (read/write/execute permissions, authentication requirements, and monotonic counter dependencies). Each object can be individually secured with integrity and confidentiality protection, supporting fine-grained credential and key separation.

What is the maximum I²C clock frequency supported in Shielded Connection mode?

The device supports Fast Mode Plus (1 MHz) in Shielded Connection mode. Timing compliance is verified per Table 10 of the datasheet (Z8F80311641-D Rev 3.70), with tLOW = 0.5 µs minimum and tHIGH = 0.26 µs minimum at VCC = 3.3 V and TA = 25 °C.

Is GPIO pin capable of driving a MOSFET gate directly for hibernate control?

No. GPIO is a CMOS output rated for ≤ 4 mA sink/source and is intended for logic-level signaling only. Driving a MOSFET gate requires external level-shifting or buffer circuitry (e.g., single-NMOS with pull-down, as shown in Figure 4 of the datasheet) to ensure reliable VCC gating during hibernate entry/exit.
