Infineon Technologies SLE88CFX4000PVQFN10ZZZA1

Overview

SLE88CFX4000PVQFN10ZZZA1 from Infineon Technologies is a 32-bit security controller optimized for multi-application smart cards, featuring 400 kBytes of flexible EEPROM with Flash functionality, 16 kBytes RAM, hardware-based Memory Encryption/Decryption (MED), and Common Criteria EAL5+ certification. It integrates a pipelined RISC CPU, DES accelerator, True RNG (AIS31-compliant), and Memory Management and Protection Unit (MMU) with 256 hardware-isolated packages.

For engineers reviewing the SLE88CFX4000PVQFN10ZZZA1 datasheet, SLE88CFX4000PVQFN10ZZZA1 pinout, SLE88CFX4000PVQFN10ZZZA1 application, or SLE88CFX4000PVQFN10ZZZA1 equivalent, key selection criteria include ISO/IEC 7816 T=0/T=1 UART support, 1–10 MHz external clock range, 1.62–5.5 V supply, -25°C to +85°C operation, and hardware-enforced memory partitioning for secure Java Card execution.

Technical Context

The device implements a proprietary 32-bit RISC core in 0.13 µm technology with dual instruction/data caches and hardware-accelerated pre-emptive multitasking. Its MMU enforces strict memory isolation across 256 packages using hardware firewalls, while the Intelligent Power Manager dynamically scales internal clock frequency (up to 66 MHz) per power class A/B/C.

Security is implemented at silicon level: active shield, voltage/frequency/light/temperature/glitch sensors, dual-rail logic for DPA/SPADEMA resistance, and MED-encrypted EEPROM/RAM. The DES accelerator supports single and triple DES operations; TRNG output complies with AIS31 Class P2 requirements.

FAQ

What is the maximum internal clock frequency achievable with SLE88CFX4000PVQFN10ZZZA1?

The device supports an internal CPU clock up to 66 MHz, generated by its integrated PLL from an external 1–10 MHz clock input. Frequency scaling is managed automatically by the Intelligent Power Manager according to configured power class (A/B/C), ensuring optimal performance-per-watt for each operational mode.

Does SLE88CFX4000PVQFN10ZZZA1 support contactless communication natively?

No, it does not integrate a contactless RF front-end. It supports only ISO/IEC 7816-3 contact interface via its dedicated I/O pin. For dual-interface cards, this controller must be paired with a separate contactless controller (e.g., Infineon SLB9670) and coordinated via shared memory or inter-chip messaging.

How is memory partitioning enforced between applications on this device?

Partitioning is enforced by the hardware Memory Management and Protection Unit (MMU), which divides address space into 256 isolated packages. Each package has configurable read/write/execute permissions for memory regions and peripheral access rights, enforced at bus level - no software bypass is possible even under kernel-mode execution.

Is flash initialization supported for field updates after personalization?

Yes, flash initialization is supported upon request through Infineon's secure personalization services. This enables post-manufacturing loading of operating system images, applets, and cryptographic keys - a key differentiator for service providers requiring flexible, phased UICC deployment.
