The AT90SC104104CV is a low-power, high-performance, 8-/16-bit microcontroller with FLASH program memory, EEPROM memory, based on RISC architecture microcontroller. By executing powerful instructions in a single clock cycle, the AT90SC104104CV 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.
In addition to the 104K bytes of FLASH, the AT90SC104104CV includes 104K bytes of high density EEPROM. 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 theversatile 8/16-bit CPU on a monolithic chip provides a highly flexible and cost-effective solution to many smart card applications
