*AES/TDES available on AT91SAM7XC only.
Atmel’s AT91SAM7X and AT91SAM7XC 32-bit microcontrollers are designed for extensively networked,
real-time embedded control applications that require USB, Ethernet and CAN. Based on the industry-
standard ARM7TDMI
®
core, the AT91SAM7X(C) boosts performance via deterministic processing, ensuring
high-speed communication with low CPU overhead. For applications requiring maximum security for
streaming content, the AT91SAM7XC integrates crypto co-processors.
