Description
The A7001 family is a tamper resistant secure Micro Controller Unit (MCU) family using a dedicated security hardened MX51CPU. NXP Semiconductors has a long track record in security MCUs. NXP ICs have been used in all types of security applications such as bank cards, health insurance cards, electronic passports, and pay-TV cards. They have also been used as embedded secure element in mobile phones. The A7001 family features a significantly enhanced secure microcontroller architecture. Extended instructions for Java and C code, linear addressing and high speed at low power are among many other improvements added to the classic 80C51 core architecture.
