AT91SAM 32 bit ARM® RISC MCUs
The SAM7X and SAM7XC Series |

Single Chip ARM7TDMI for General Purpose with USB, CAN and Ethernet
The AT91SAM7X / XC microcontroller family is Flash based
with integrated Ethernet, USB and CAN interface, and security
features, based on the 32-bit ARM7TDMI RISC processor. It features up to 512K
bytes of embedded high-speed Flash with sector lock capabilities and a security
bit, and up to 128K bytes of SRAM. The integrated proprietary SAM-BA
Boot Assistant enables in-system programming of the embedded Flash.
Its extensive peripheral set includes a USB 2.0 Full Speed Device Port, Ethernet
MAC 10/100 base T, CAN 2.0A and 2.0B compliant Controller, configurable 128-,
192- or 256-bit ("Top Secret") AES or Triple DES encryption
accelerator (SAM7XC family only) , USARTs, SPI, SSC, TWI and an 8-channel 10-bit
ADC. Its Peripheral DMA Controller channels eliminate processor
bottlenecks during peripheral-to-memory transfers.
Its System Controller manages interrupts, clocks, power, time, debug and
reset, significantly reducing the external chip count and minimizing power
consumption.
In industrial temperature, worse case conditions the maximum clock frequency is
55MHz. Typical core supply is 1.8V, I/Os are supplied at 1.8V or 3.3V and are 5V
tolerant. An integrated Voltage Regulator permits single supply operation at
3.3V. The AT91SAM7X/XC family is supplied in a 100-lead LQFP and BGA100 Green
package. It is supported by an Evaluation Board and extensive application
development tools.
The AT91SAM7X/XC family members are general-purpose microcontrollers,
particularly suited to secured real-time embedded control applications that
require USB connectivity as well as Ethernet, CAN and/or ZigBee networking.
