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.
