SLE 66C168PE MFC5.6

Application Specific Microcontrollers Overview

The Infineon SLE 66C168PE 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 (256 internal, 2048 XRAM), and 16 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. Key hardware accelerators include Dual Key Triple DES, a True Random Number Generator, and a CRC module. It features an enhanced Memory Management Unit for secure OS/application separation and supports external clock frequencies up to 7.5 MHz.

Application Specific Microcontrollers Procurement Notes

Verify package availability as the component is offered as sawn die or wire-bonded modules. Confirm specific voltage ranges and temperature grades during ordering. Contact sales representatives for detailed qualification reports and chip delivery specifications. Ensure compliance with life-support usage restrictions requiring written approval.

Application Specific Microcontrollers Selection Notes

Select based on required supply voltage (1.8V, 3.0V, or 5.0V) and operating temperature (-25°C to +70°C or +85°C). Choose between die or module packaging depending on integration needs. Consider the internal PLL capabilities for performance optimization versus power consumption constraints defined by GSM/UICC standards.

Application Specific Microcontrollers Part Context

This component belongs to the improved 66PE series from Infineon Technologies. It maintains downward compatibility with existing SLE 66CxxxP products while offering increased memory sizes, enhanced performance via the ECO2000 core, and advanced security features like the MMU and DDES accelerator.

Application Specific Microcontrollers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Existing SLE 66CxxxP derivatives offer downward compatibility but lack the enhanced memory and performance features of this model.
