SMART ARM MICROCONTROLLERS

Ò AT91SAM7X and AT91SAM7XC ARM Microcontrollers

For Real-time Ethernet Networking

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 industrystandard 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.
