SLS32AIA010MKUSON10XTMA3

Application Specific Microcontrollers Overview

The Infineon OPTIGA™ Trust M (SLS32AIA010MK) is a high-end security controller based on Common Criteria EAL 6+ (high) certified hardware and PSA Level 3 certified. It provides up to 10 kB of user memory for storing X.509 certificates, keys, and arbitrary data. The device supports I2C communication with Shielded Connection capabilities and operates within a standard temperature range of -25°C to +85°C. Cryptographic features include ECC NIST curves up to P-521, RSA up to 2048 bits, AES up to 256 bits, and hashing up to SHA-512. It includes four monotonic counters and supports hibernation with leakage current below 2.5 µA.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix 'K' corresponds to the Standard Temperature Range (-25°C to +85°C) as defined in the product table. Confirm package type PG-USON-10-2,-4 matches design requirements. Ensure compatibility with the OPTIGA™ Trust M Software Framework available on GitHub for integration.

Application Specific Microcontrollers Selection Notes

Select this model for applications requiring CC EAL 6+ (high) and PSA Level 3 certifications. Choose the MK variant for standard temperature environments (-25°C to +85°C). For extended temperature ranges (-40°C to +105°C), consider the ML or MH variants. Ensure host systems support I2C FM+ speeds up to 1 MHz.

Application Specific Microcontrollers Part Context

The SLS32AIA010MK is part of the OPTIGA™ Trust M family, specifically the V3 generation optimized for turnkey security solutions. It serves as an embedded security solution for connected devices, offering preprogrammed OS/Application code and host-side modules to facilitate rapid integration into existing ecosystems.

Application Specific Microcontrollers Replacement Considerations

For extended temperature range requirements, the SLS32AIA010MLUSON10XTMA9 (OPTIGA™ Trust M Express) or SLS32AIA010MMUSON10XTMA2 (OPTIGA™ Trust M MTR) are alternative options within the same package footprint.
