The AT91SC25672RC is a low-power, high-performance, 32-bit RISC microcontroller with ROM program memory, EEPROM data memory, and cryptographic accelerator, based on the new ARM SC100 advanced secure processor. The SC100 embedded core is the first member of the ARM SecurCore family. This general-purpose 32-bit processor offers high performance, very low power consumption, and additional features to help combat fraud.

The AT91SC25672RC features 72K bytes of high-performance EEPROM (fast erase/write time, high endurance). This allows system developers to offer their customers a true 64K bytes EEPROM, while still being able to use the remaining 8K bytes for their own purposes (e.g. customization and patches).

The cryptographic accelerator featured in the AT91SC25672RC series is the new AdvX™. It is based on a 32-bit multiplier-accumulator architecture which is designed to perform fast encryption and authentication functions. This enables fast computation and low-power operation. The AdvX, in conjunction with controlling firmware running within the SC100 core, supports standard finite fields arithmetic functions (including RSA, DSA, DH, ECC) and GF(2N).

On top of the AT91SC25672RC´s MPU, a real hardware firewall can be used to increase the overall security level of the application without intense software development. Unique hardware features significantly accelerate the execution of Java Card Byte Code by removing the common software bottlenecks encountered during the implementation of a Java Virtual Machine.

Additional AT91SC25672RC security features include power and frequency protection logic, logical scrambling on program data and addresses, power analysis countermeasures and memory accesses controlled by a supervisor mode.
