Product details

Overview

SLE76CF5120PVQFN8ZZZA1 from Infineon Technologies is a 16-bit secure microcontroller with integrated cryptographic accelerators, 512 KB Flash, 64 KB RAM, and ISO/IEC 15408 EAL5+ certified security architecture. It operates at up to 80 MHz, supports AES-128/256, RSA-2048, ECC, and SHA-256, and targets tamper-resistant smart card and secure identity applications.

For engineers reviewing the SLE76CF5120PVQFN8ZZZA1 datasheet, SLE76CF5120PVQFN8ZZZA1 pinout, SLE76CF5120PVQFN8ZZZA1 application, or SLE76CF5120PVQFN8ZZZA1 equivalent, key selection criteria include certified secure boot, side-channel resistant crypto execution, contact/contactless interface support per ISO/IEC 7816-3 and ISO/IEC 14443 Type A/B, and QFN-8 package thermal and layout constraints.

Technical Context

This device implements a hardened 16-bit C166S V2 core with memory protection unit (MPU), dedicated hardware for asymmetric crypto (RSA/ECC) and symmetric crypto (AES/SHA), and dual-interface controller supporting both ISO/IEC 7816-3 (contact) and ISO/IEC 14443-A/B (contactless) protocols in a single chip. It includes secure key storage with battery-backed SRAM and physical tamper detection sensors.

The security subsystem enforces strict isolation between application code and secure firmware via hardware-enforced privilege levels, and all cryptographic operations execute inside a shielded, voltage- and frequency-monitored secure execution environment compliant with Common Criteria EAL5+ evaluation assurance level.

Equivalent & Alternatives

The following parts are listed as comparable options for similar secure microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon SLB9670	ARM Cortex-M3 core, TPM 2.0 compliant, 256 KB Flash, no contact/contactless interfaces	Designed for PC/server TPM slots; lacks ISO/IEC 7816/14443 support	Select when platform requires standardized TPM interface instead of smart card protocols
NXP JCOP41	ARM SecurCore SC300, 1 MB Flash, Java Card OS, EAL5+ certified, same dual-interface capability	Java Card runtime enables applet-based multi-application deployment	Select when application requires dynamic loading of multiple certified applets (e.g., eHealth + ePayment on one card)

FAQ

What security certifications does the SLE76CF5120PVQFN8ZZZA1 hold?

The SLE76CF5120PVQFN8ZZZA1 is certified to ISO/IEC 15408 EAL5+ with AVA_VAN.5 augmentation, covering resistance to physical probing, differential power analysis, electromagnetic analysis, and fault injection. It also complies with Common Criteria Protection Profile for Smart Cards (PP0084) and meets FIPS 140-2 Level 3 requirements for cryptographic module validation.

Does this device support both contact and contactless interfaces simultaneously?

Yes-the SLE76CF5120PVQFN8ZZZA1 integrates a dual-interface controller that supports ISO/IEC 7816-3 (contact) and ISO/IEC 14443-A/B (contactless) protocols on shared secure resources. It automatically detects interface activation and switches context without external arbitration logic or firmware reconfiguration.

What is the maximum operating frequency and voltage range?

The device operates at up to 80 MHz CPU frequency with a core supply of 1.8 V ±10 %. Internal regulators derive 1.2 V for the core and 3.3 V for I/O circuits. The absolute maximum VDD rating is 2.0 V; operation outside 1.62–1.98 V invalidates security certification and may cause functional failure.

Is the QFN-8 package lead-free and RoHS compliant?

Yes-SLE76CF5120PVQFN8ZZZA1 uses a lead-free, halogen-free, RoHS-compliant VQFN package with matte tin surface finish. The package meets JEDEC J-STD-020D moisture sensitivity level 3 (MSL3) and is qualified for reflow soldering per IPC/JEDEC J-STD-020.
