The AT91SAM7X128 is a Flash microcontroller with integrated
Ethernet, USB and CAN interface, based on the 32-bit ARM7TDMI RISC
processor. It features 128K bytes of embedded high-speed Flash with
sector lock capabilities and a security bit, and 32K 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, 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 at
3.3V. The AT91SAM7X128 is supplied in a 100-lead LQFP Green
package. It is supported by an uation Board and extensive
application development tools.
