Description
The AT90SC256144RCFT is a low-power, high-performance, 8/16-bit microcontroller with ROM program memory, EEPROM data memory
and a crypto-accelerator, based on the secureAVR enhanced RISC architecture.
By executing powerful instructions in a single clock cycle, the AT90SC256144RCFT achieves throughputs close to 1 Millions of Instructions
per Second (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 that allows the linear addressing code and 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, DH and ECC) and GF(2N) arithmetic functions (including
ECC).
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 mainly targets Access Control and ID applications.
