Infineon Technologies SLE 66C44PE MFC5.8

Overview

SLE 66C44PE MFC5.8 from Infineon Technologies is an 8/16-bit security controller IC for smart card applications, featuring 68-Kbyte ROM, 2304-Byte RAM (256-byte IRAM + 2048-byte XRAM), 4-Kbyte MicroSlim-EEPROM, dual-key Triple DES accelerator, and EAL5+ certification targeting. It executes at up to 33 MHz internal clock (PLL ×4), supports ISO/IEC 7816 T=0/T=1 protocols, and operates across 1.8 V / 3.0 V / 5.0 V supply rails.

For engineers reviewing the SLE 66C44PE MFC5.8 datasheet, SLE 66C44PE MFC5.8 pinout, SLE 66C44PE MFC5.8 application in EMV payment cards or UICC personalization, or SLE 66C44PE MFC5.8 equivalent for secure multi-application smart card platforms, this page delivers verified technical context, memory architecture details, cryptographic timing metrics, and certified security feature mapping.

Technical Context

The SLE 66C44PE implements an enhanced ECO2000 8/16-bit CPU core with SAB 8051 opcode compatibility and dedicated instructions for >64 KB physical memory access-enabling full 16-MB addressability upon request. Its Memory Management and Protection Unit (MMU) enforces strict OS/application mode separation using 16 configurable descriptors and application-oriented memory segments.

Security execution relies on hardware-accelerated Dual Key Triple DES (DDES) with encryption times of 5.3 µs per 64-bit block at 33 MHz, a True Random Number Generator with firmware test function, CRC-16 module per ISO/IEC 3309, and active shield with glitch/light/voltage/frequency/temperature sensors plus UMSLC life-test capability.

FAQ

What is the maximum supported external clock frequency for SLE 66C44PE MFC5.8?

The SLE 66C44PE MFC5.8 accepts an external clock input ranging from 1 MHz to 7.5 MHz, as specified in the Short Product Information v01.05. This signal feeds the internal PLL, which scales it to generate the core clock-up to 33 MHz-with programmable multiplication factors (×1, ×2, ×3, or ×4).

Does SLE 66C44PE MFC5.8 support ISO/IEC 14443 contactless communication?

No. The SLE 66C44PE MFC5.8 is a contact-only smart card controller with a single I/O pin compliant exclusively with ISO/IEC 7816-3 for T=0 and T=1 protocols. It lacks RF front-end circuitry, antenna drivers, or modulation/demodulation blocks required for ISO/IEC 14443-A/B or NFC operation.

How is the 32-byte security PROM protected on SLE 66C44PE MFC5.8?

The 32-byte security PROM is hardware-locked after initial programming and accessible only by privileged OS routines. It stores batch-, wafer-, and die-individual security data-including unique chip identification-and is isolated from application-level read/write access by the MMU and dedicated bus protection logic.

Can SLE 66C44PE MFC5.8 execute code directly from EEPROM?

No. Code execution is supported only from ROM and XRAM. The MicroSlim-EEPROM is designated for persistent data storage (keys, counters, applet parameters) and is not mapped into the instruction fetch path. The MMU enforces strict separation between executable and data memory spaces to prevent runtime code injection attacks.
