Development Tools • Voyager Emulation Platform (ATV4) to Support Software Development • IAR Embedded Workbench® V4.20 Debugger or Atmel’s AVR Studio® Version 4.07 or Above • Software Libraries and Application Notes Description The AT90SC28872RCU is a low-power, high-performance, 8/16-bit microcontroller with ROM program memory, EEPROM memory, based on the SecureAVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the AT90SC28872RCU 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 288K bytes of embedded ROM, the AT90SC28872RCU includes 72K of Atmel’s 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 the versitile 8/16-bit CPU on a monolithic chip provides a highly flexible and cost-effective solution to many smart card applications.
