Infineon technological company implements it newest high and safe microcontroller family, SLE 78, phones to a hardware safe practice ” Intact guard. ” The hardware safe practice can be offered in SLE 39 kilometers. Infineon develops SLE 78 families and honest guards and uses requiring on the basis of the integrated chip card and what the security personnel employed and required alikely very much, in paying and course of appraising the field of government.

According to Infineon, intact guards safe MCUses are equipped with the comprehensive mistake and perceived ability. Pairs of CPU close to, allow mistake perceive and find first calculate, go on and have no mistake while dealing with even. The attempt that a mistake or once attacked after measuring, MCU can determine that the operation whether an alarm will initiate and will be stopped is automatic to operate continuing.

In addition, SLE 78 is equipped with the abundant encryption about slice the key building and data thorough fare, include all memories (EEPROM, glistens, ROM, RAM) ,The bus, high-speed buffer memory and two CPUs.

Calculation that the complete hardwares of different secret keys that two CPUs use having in two CPUs encrypted.

SLE 78 6 member’s samples in safe MCU family are free in quantity. Apparatus the in EEPROM size with and offer the memory between 36 Kbyte and 144 Kbyte. The volume is produced and expected to begin in Q1 09.
