Description

The AT90SC6464C-USB is a low-power, high-performance, 8-bit microcontroller, based on the new AVR3 enhanced RISC architecture, featuring Flash program memory, EEPROM data memory and a 16-bit crypto-coprocessor dedi-cated to performing fast encryption and authentication functions.

The new AVR3 core allows linear addressing of up to 8M bytes of code and up to 16M bytes of data, and provides a number of new functional and security features. This new core executes powerful instructions in a single clock cycle, and allows the AT90SC6464C-USB to achieve throughputs close to 1 MIPS per MHz. The Harvard architecture includes 32 generalpurpose working registers directly connected to the ALU, allowing two independent registers to be accessed in one single instruction executed in one clock cycle.

The AT90SC6464C-USB includes 128K bytes of Atmel's high density, nonvolatile memory. The on-chip downloa-dable 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.

Additional security features of AT90SC6464C-USB include power and frequency protection logic, logical scrambling on program data and addresses, Power Analysis countermeasures and memory accesses controlled by a supervisor mode.
