Description
The AT90SC19272RC 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 AT90SC19272RC 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 AT90SC19272RC 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 dedicated 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 AT90SC19272RC is shown in Figure 1.
