Secure Microcontroller For Smart Cards - Atmel Corporation

The AT90SC19272RC is a low-power, high-performance, 8-/16-bit Microcontroller based on the secureAVR RISC architecture, with ROM program memory, EEPROM data memory and a crypto-coprocessor. By executing powerful instructions in a single Clock cycle, the AT90SC19272RC 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 AT90SC19272RC uses secureAVR architecture that allows the linear addressing of up to 8M bytes of code and up to 16M bytes of data, and also provides a number of new functional and security features. The crypto engine featured in the AT90SC series is the SC16, a 16-bit processor dedi- cated to performing fast encryption and authentication functions. 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.
