Development Tools • Voyager Emulation Platform (ATV4 Advanced) to Support Software Development • IAR Embedded Workbench® V3.20c Debugger or Atmel’s AVR Studio® Version 4.07 or Above • Software Libraries and Application Notes Description The AT90SC6404RFT is a low-power, high-performance, 8-/16-bit microcontroller with ROM program memory, EEPROM data memory, based on the secureAVR enhanced RISC architecture and with a contactless interface. By executing powerful instructions in a single clock cycle, the AT90SC6404RFT 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 AT90SC6404RFT uses the secureAVR architecture 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 AT90SC6404RFT features 04K bytes of high-performance EEPROM (fast erase/write time, high endurance). The ability to map the EEPROM in the code space allows parts of the program memory to be reprogrammed in-system. Additional security features include 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 targets Transport and Banking applications. Figure 1 shows a block diagram of the AT90SC6404RFT. Figure 1. Block diagram of AT90SC6404RFT.
