AT90SC28880RCFV
Description
The AT90SC28880RCFV is a low-power, high-performance, 8/16-bit microcontroller with ROM program memory, EEPROM
data memory and a crypto-accelerator, based on the secureAVR enhanced RISC architecture. By executing powerful
instructions in a single clock cycle, the AT90SC28880RCFV 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 regis-
ters to be accessed in one single instruction executed in one clock cycle.
In addition to the 288K bytes of embedded ROM, the AT90SC28880RCFV includes 80K 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 versitile 8/16-bit CPU on a monolithic chip provides a highly flexible and cost-effective
solution to many smart card applications.
The AT90SC28880RCFV uses the secureAVR® that allows the linear addressing of code and data as well as a number of
new functional and security features.
The crypto engine featured in the AT90SC series is the AdvX, a 32-bit accelerator dedicated to perform fast encryption or
authentication functions.
Additional security features include power, frequency and temperature protection logic, logical scrambling on program data
and addresses, Power Analysis countermeasures and memory accesses controlled by a supervisor mode.
