By executing powerful instructions in a single clock cycle, the AT90SC3232 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 AT90SC3232 includes 64K bytes of Atmel's high density, nonvolatile memory. The on-chip downloadable Flash allows the Program memory to be reprogrammed in-system. This technology combined with the versatile 8-bit CPU on a monolithic chip provides a highly flexible and cost-effective solution to many smart card applications.
