Description
The AT90SC3232 is a low-power, high-performance, 8-bit microcontroller with Flash
Program memory and EEPROM Data memory, based on the AVR enhanced RISC
architecture. 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-sys-
tem. 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.
