By executing powerful instructions in a single clock cycle, the AT90SC256144RCFT achieves throughputs close to 1 MIPS per MHz. Its Harvard architecture includes 32 general-purpose working registers directly connected to the ALU, allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The AT90SC256144RCFT uses the secureAVR architecture that allows the linear addressing of up to 8M bytes of code and up to 16M bytes of data as well as a number of new functional and security features. The AT90SC256144RCFT features 144K bytes of high-performance EEPROM (fast erase/write time, high endurance).This allows system developers to offer their customers a true 128K bytes EEPROM, while still being able to use the remaining 16K bytes for their own purposes (customization and patches, for example). The ability to map the EEPROM in the code space allows parts of the program memory to be reprogrammed in-system. The cryptographic accelerator featured in the AT90SC256144RCFT is the new AdvX, a N-bit multiplier-accumulator dedicated to performing fast encryption and authentication functions. All cryptographic routines are executed on the secureAVR core which uses the AdvX accelerator during encryption/decryption. AdvX is based on a 32-bit technology, thus enabling fast computation and low power operation. AdvX supports standard finite fields arithmetic functions (including RSA, DSA and DH) and GF(2N) arithmetic functions (including ECC). An AES 128 Engine is provided as an optional feature. Additional security features include power, frequency and temperature protection logic, logical scrambling on program data and addresses, power analysis countermeasures, and memory accesses controlled by a supervisor mode. This product is specifically designed for Smart Cards and targets Access Control and ID applications.
