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.

The AT91SAM7X-EK and AT91SAM7XC-EK
development kits enable evaluation capabilities
and code development for applications
running on the AT91SAM7X and
AT91SAM7XC microcontrollers
respectively. The development
kit package contains following
items:
■ an AT91SAM7X
or AT91SAM7XC
Evaluation Board
■ one A/B-type USB cable
■ one crossed serial RS232 cable
■ one RJ45 crossed Ethernet cable
■ universal input AC/DC power supply with US and EU plug
adapter
■ a DVD-ROM containing summary and full datasheets with electrical and
mechanical characteristics, application notes and getting started documents for all
AT91 microcontrollers. An AT91 software package with C and Assembly listings is also provided. All this
allows a user to begin evaluating an AT91 ARM®Thumb®32-bit microcontroller quickly and easily.
