Overview
The Infineon SLE 66C44PE is an 8/16-bit security controller manufactured in 0.22 µm CMOS technology, featuring the ECO2000 CPU core with SAB 8051 opcode compatibility. It integrates 68 Kbytes of User ROM, 2304 Bytes of RAM (2K XRAM and 256 internal), and 4 Kbytes of MicroSlim-EEPROM. The device supports supply voltages of 1.8 V, 3.0 V, or 5.0 V and operates within a temperature range of -25°C to +85°C. It includes a Dual Key Triple DES accelerator, a True Random Number Generator, and a Memory Management Unit for secure multi-application support.
Feature Summary
- ECO2000 8/16-bit CPU with enhanced instructions for direct physical memory access up to 16 Mbyte
- Dual Key Triple DES (DDES) accelerator with encryption times as low as 3.5 µs at 33 MHz
- Memory Management and Protection Unit (MMU) separating OS and application modes
- Integrated security sensors including voltage, frequency, light, glitch, and temperature detectors
Applications
- SDA payment applications
- EMV migration loyalty applications
- Identification systems requiring high security levels
Procurement Notes
Verify the specific ordering suffix (e.g., M5.1 for module, C for die) to confirm voltage range and temperature grade. Confirm availability status as the product information is marked preliminary and subject to change. Contact Infineon Technologies directly for current qualification reports and chip delivery specifications.
Selection Notes
Select based on required operating voltage (1.8 V, 3.0 V, or 5.0 V) and package type (wire-bonded module M5 or sawn/unsawn die C). Ensure the external clock frequency (1–7.5 MHz) aligns with the desired internal PLL multiplication factor up to 33 MHz. Verify that the 68 Kbyte ROM size meets application code requirements to preserve EEPROM for customer data.
Part Context
The SLE 66C44PE belongs to the improved 66PE series of security controllers from Infineon Technologies. It maintains downward compatibility with existing SLE 66CxxxP products while offering increased performance and memory capacity. The device is designed for smart card environments requiring robust security and multi-application capabilities.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Existing SLE 66CxxxP derivatives may offer functional compatibility but lack the enhanced memory and instruction set features of the 66PE series.
