Description The AT90SC25672R is a low-power, high-performance, 8/16-bit microcontroller with ROM program memory, EEPROM data memory, based on the secureAVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the AT90SC25672R 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 AT90SC25672R uses a new AVR architecture, the secureAVR 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 ability to map the EEPROM in the code space allows parts of the program memory to be reprogrammed in-system. This technology combined with the versatile 8/16-bit CPU on a monolithic chip provides a highly flexible and cost-effective solution to many smart card applications. Additional 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.
