mance, 8-bit microcontroller with ROM program memory, EEPROM data memory and a crypto-coprocessor, based on the
AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the AT90SC19264RC
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 AT90SC19264RC uses a new AVR core (core #3) that allows the linear addressing of up to 8M bytes of code and up to
16M bytes of data as well as a number of new functional and security features.
The crypto engine featured in the AT90SC series is a 16-bit processor dedicated to perform fast encryption or authentica-
tion functions. 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.
