Description
The AT90SC320288RCT is a low-power, high-performance, 8/16-bit microcontroller with ROM program memory,
EEPROM data memory, based on the secureAVR enhanced RISC architecture. By executing powerful instructions in a sin-
gle clock cycle, the AT90SC320288RCT 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 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 8/16-bit CPU on a monolithic chip provides a highly flexible and cost-effective
solution to many smart card applications. The AT90SC320288RCT benefits of advanced EEPROM functions (XP Mode),
but can also be configured to offer compatibility with previous product generations (e.g. AT90SC25672R or
AT90SC19236R).
The cryptographic accelerator, running with the secureAVR core, featured in the AT90SC320288RCT series is the new
AdvX. It is based on a 32-bit multiplier-accumulator architecture which is designed to perform fast encryption and authen-
tication functions. This enables fast computation and low-power operation. The controlling firmware is located either in the
dedicated ROM memory (Atmel’s cryptolibrary supports standard finite field arithmetic functions including RSA, DSA, DH
and ECC) or in the ROM program memory (customer specific).
Additional security features include power and frequency protection logic, logical scrambling on program data and
addresses, Power Analysis countermeasures and memory accesses controlled by a supervisor mode.
