Product details

Overview

SLE 66C84PE MFC5.8 from Infineon Technologies is a 16-bit security controller with integrated DES/Triple-DES, RSA up to 2048-bit, and SHA-1 cryptographic accelerators; features 64 KB ROM, 8 KB RAM, and 128 KB EEPROM; used in contact-based smart card applications requiring secure authentication and data integrity.

For engineers reviewing the SLE 66C84PE MFC5.8 datasheet, SLE 66C84PE MFC5.8 pinout, SLE 66C84PE MFC5.8 application, or SLE 66C84PE MFC5.8 equivalent, key selection criteria include cryptographic algorithm support, memory configuration, ISO/IEC 7816-3 compliance, and secure boot capability.

Technical Context

This device implements a dedicated 16-bit CISC core optimized for secure transaction processing, with hardware-assisted crypto engines decoupled from main CPU execution. It supports ISO/IEC 7816-3 T=0 and T=1 protocols via its integrated UART with automatic protocol handling and clock frequency adaptation from 1–5 MHz.

The security architecture includes tamper detection logic, voltage/frequency/glitch monitors, and secure memory partitioning enforced by a hardware memory management unit (MMU); all cryptographic keys are stored exclusively in protected EEPROM zones accessible only through authenticated secure channel sessions.

Key Specifications

Parameter	Value and Actual Design Meaning
CPU Core	16-bit CISC architecture with 32-bit ALU; enables deterministic instruction timing for side-channel resistant firmware execution.
Cryptographic Acceleration	Hardware DES/Triple-DES, RSA-2048, SHA-1; offloads compute-intensive operations, reducing host CPU load and improving transaction throughput.
Memory	64 KB ROM (firmware), 8 KB RAM (volatile session data), 128 KB EEPROM (persistent secure storage); supports wear-leveling and atomic write protection.
Interface	ISO/IEC 7816-3 compliant UART with T=0/T=1 protocol engine; eliminates need for external protocol controller in smart card readers.
Security Features	Tamper detection, voltage/frequency/glitch monitoring, secure boot, MMU-enforced memory isolation; meets Common Criteria EAL5+ evaluation assurance level.
Operating Voltage	2.7–5.5 V; compatible with standard smart card power supply profiles including Class A/B/C per ISO/IEC 7816-3.

Pinout & Package

Package: 44-pin QFP (Quad Flat Package), 10 mm × 10 mm, 0.8 mm pitch, lead-free, RoHS-compliant.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Supply voltage input	Primary power rail for core and peripheral logic; requires local 100 nF decoupling per supply pin.
GND	Ground reference	Dedicated analog/digital ground return; must be connected to low-impedance PCB plane.
I/O	ISO/IEC 7816-3 contact I/O	Bidirectional serial interface supporting T=0 and T=1 protocols; includes internal pull-up and ESD protection.
RST	Reset input	Active-low asynchronous reset; initiates secure boot sequence and clears volatile registers.
CLK	External clock input	Accepts 1–5 MHz crystal or external clock; drives internal PLL for core and crypto engine timing.
VPP	Programming voltage input	Required for EEPROM programming cycles; typically 5.5 V ±0.25 V during write/erase operations.

Key Features

Feature	Design Value
Secure Boot with Signature Verification	Ensures only cryptographically signed firmware executes, preventing unauthorized code injection during power-on initialization.
Hardware Crypto Engine Isolation	Separate bus and clock domains for crypto accelerators prevent timing side-channel leakage during concurrent CPU operation.
EEPROM Wear-Leveling & Atomic Write	Extends endurance beyond 500,000 write cycles and guarantees data consistency even during unexpected power loss.
Integrated Tamper Detection Circuitry	Monitors environmental anomalies (voltage drop, clock glitch, temperature shift) and triggers immediate secure memory wipe on violation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar security controller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon SLB 9670	ARM Cortex-M3 core, TPM 2.0 compliant, no EEPROM, uses external flash; higher performance but lacks embedded non-volatile program storage.	Designed for PC/platform TPM modules, not contact smart cards; requires external secure storage for persistent keys.	Select when integrating into motherboard-level trusted platform modules rather than embedded contact IC cards.
NXP JCOP41	JavaCard OS-based, 32-bit ARM SC300 core, 128 KB EEPROM, supports GlobalPlatform 2.3; software-centric security model vs. SLE's hardware-rooted enforcement.	Targeted at multi-application applet environments (e.g., transit + banking on single card); less deterministic timing for side-channel resistance.	Select when JavaCard applet flexibility and multi-issuer support outweigh strict side-channel mitigation requirements.

Compared with SLB 9670 and JCOP41, the SLE 66C84PE MFC5.8 uniquely combines hardware-isolated crypto acceleration, on-die EEPROM, and deterministic CISC execution-making it optimal for high-assurance, single-purpose contact smart cards where physical tamper resilience and certification traceability are mandatory.
