Description The AT90SC3232CS is a low-power, high-performance, 8-/16-bit microcontroller, based on the secure AVR RISC architecture, with Flash program memory, EEPROM data memory and a crypto-coprocessor. By executing powerful instructions in a single clock cycle, the AT90SC3232CS 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 AT90SC3232CS uses a new secure AVR CPU 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 AT90SC3232CS includes 64K bytes of Atmel's high density, non volatile memory. The on-chip Flash allows the program memory to be reprogrammed in-system and locked securely. This technology combined with the versatile CPU on a monolithic chip provides a highly flexible and cost-effective solution to many smart card applications. The crypto engine featured in the AT90SC series is the SC16, a 16-bit processor dedicated 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.
