Description
The AT90SC9618RT is a low-power, high-performance, 8/16-bit microcontroller with ROM program memory and EEPROM
data memory, based on the secureAVR RISC architecture. By executing powerful instructions in a single clock cycle, the
AT90SC9618RT 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 instruc-
tion executed in one clock cycle.
The AT90SC9618RT uses the secureAVR 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 AT90SC9618RT includes 18K bytes of Atmel’s high density, non volatile memory.
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.
