Description
The AT90SC6432R is a low-power, high-performance, 8-bit/16-bit microcontroller with ROM and EEPROM memory, based
on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the AT90SC6432R
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.
On top of the 64K bytes of embedded ROM, the AT90SC6432R includes 32K bytes of Atmel's high density EEPROM. The
ability to map the EEPROM in the code space allows parts of the program memory to be reprogrammed in-system. This
technology combined with the versatile 8-bit/16-bit microcontroller provides a highly flexible and cost-effective solution to
many smart card applications.
The 8-bit/16-bit microcontroller provides extended indirect addressing capabilities, including 16-bit Pointers, for large mem-
ory addressing.
