Description
The AT90SC series 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 AT90SC
achieves throughputs of 1 MIPS per MHz. Its Harvard architecture includes 32 gen-
eral-purpose working registers directly connected to the ALU, allowing two indepen-
dent registers to be accessed in one single instruction executed in one clock cycle.
Some products in the AT90SC family feature a cryptoprocessor: a 16-bit crypto
engine dedicated to performing fast encryption or authentication functions (see table
below). Additional security features include power and frequency protection logic, log-
ical scrambling on program data and addresses, and memory accesses controlled by
a supervisor mode.
The AT90SC family provides up to 96K bytes of Atmel’s high-density, nonvolatile
memory technology. 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.
