Description
The AT90SC6408RFT 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 dual interface (contact+contactless). The contactless interface fully supports the ISO/IEC 14443 Type A and Type B standard. By executing powerful instructions in a single clock cycle, the AT90SC6408RFT 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 AT90SC6408RFT 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 AT90SC6408RFT features 8K 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 power, frequency and 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 Dual Interface Smart Cards and targets, Banking, Transportation, Access Control and e-identity applications. A block diagram of the AT90SC6408RFT is shown in Figure 1.
