Infineon Technologies SLS32AIA010MKUSON10XTMA2

Overview

SLS32AIA010MKUSON10XTMA2 from Infineon is a Common Criteria EAL 6+ and PSA Level 3 certified security controller implementing I²C-based encrypted communication via Shielded Connection, featuring up to 10 kB user memory, ECC (NIST P-521, Brainpool r1 up to 512), RSA-2048, AES-256, SHA-256/512, and hibernate mode with leakage current < 2.5 µA - deployed in industrial control systems for secure firmware authentication.

For engineers reviewing the SLS32AIA010MKUSON10XTMA2 datasheet, SLS32AIA010MKUSON10XTMA2 pinout, SLS32AIA010MKUSON10XTMA2 application, or SLS32AIA010MKUSON10XTMA2 equivalent, key selection criteria include CC EAL 6+ certification status, I²C shielded interface compliance, hibernate power budget (<2.5 µA), monotonic counter count (4), and PG-USON-10 package compatibility with 3 mm × 3 mm board space constraints.

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, supporting TLS v1.2 PRF and HKDF key derivation. Its security monitor enforces configurable policies and logs 19 distinct security events including unauthorized access attempts and counter overflows.

It operates across standard (–40°C to +85°C) and extended (–40°C to +105°C) temperature ranges, supports I²C standard/fast/fast-mode-plus (up to 1 MHz), and implements hardware-enforced hibernation with GPIO-controlled VCC gating using single or dual MOSFET topologies per Infineon's integration schematics.

FAQ

What certifications does SLS32AIA010MKUSON10XTMA2 hold?

SLS32AIA010MKUSON10XTMA2 holds Common Criteria EAL 6+ (high) certification and PSA Certified Level 3 accreditation. These attest to its resistance against physical, fault, and side-channel attacks, and validate its secure boot, key management, and cryptographic operation integrity per internationally recognized evaluation standards.

How does the Shielded Connection feature work on this device?

Shielded Connection establishes an encrypted session layer directly over the I²C bus using pre-shared keys or asymmetric key exchange. All commands and responses - including UID reads, key imports, and signature generations - are encrypted in-flight, preventing passive eavesdropping without requiring host-side TLS stacks or additional security co-processors.

Can SLS32AIA010MKUSON10XTMA2 operate in hibernate mode while retaining secure state?

Yes - hibernate mode preserves all cryptographic keys, counters, and object metadata with leakage current < 2.5 µA. The device resumes operation within 100 µs of GPIO wake signal, retaining full security context without re-initialization or host-side re-authentication, enabling true zero-power secure standby.

Is the PG-USON-10 package compatible with standard reflow profiles?

Yes - the PG-USON-10-2,-4 package complies with IPC/JEDEC J-STD-020D moisture sensitivity level 3 and supports standard lead-free reflow profiles (peak 260°C, 60 s above 217°C). Its wettable flank design enables reliable automated optical inspection of solder joint quality on production lines.
