AT90SC4818RT

The AT90SC4818RT is a low power, high performance, 8/16-bit microcontroller based on the AVR^TM enhanced RISC architecture,with flexible ROM program memory and EEPROM data memory. By executing powerful instructions in a single clock cycle, the AT90SC4818RT 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 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 smartcard applications.The AT90SC4818RT can also be configured to offer compatibility with the AT90SC4818R and the AT90SC4816R.
