AT90SC9608RC
1581BSSMIC01/03
Description
The AT90SC9608RC is a low-power, high-performance, 8-/16-bit microcontroller, based
on the secureAVR
RISC architecture, with ROM program memory, EEPROM data
memory and a crypto-coprocessor. By executing powerful instructions in a single clock
cycle, the AT90SC9608RC 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 exe-
cuted in one clock cycle.
The AT90SC9608RC uses secureAVR architecture that allows the linear addressing of
up to 8M bytes of code and up to 16M bytes of data, and also provides a number of new
functional and security features.
The crypto engine featured in the AT90SC series is the SC16, a 16-bit processor dedi-
cated to performing fast encryption and 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.
A block diagram of the AT90SC9608RC is shown in Figure 1.
