Description  
The AT91SAM7A2 is based on the ARM7TDMI embedded processor. This processor  
has a high-performance 32-bit RISC architecture with a high-density 16-bit instruction  
set and very low power consumption.  
In addition, a large number of internally banked registers result in very fast exception  
handling, making the device ideal for real-time control applications.  
The AT91SAM7A2 has a direct connection to off-chip memory, including Flash,  
through the fully programmable External Bus Interface.  
An 8-level priority vectored Interrupt Controller in conjunction with the Peripheral Data  
Controller significantly improves the real time performance of the device. The device  
is manufactured using high-density CMOS technology.  
By combining the ARM7TDMI processor with an on-chip SRAM, and a wide range of  
peripheral functions, including USART, SPI, CAN Controllers, Timer Counter and Ana-  
log-to-Digital Converters, on a monolithic chip, the AT91SAM7A2 is a powerful device  
that provides a flexible, cost-effective solution to many compute-intensive embedded  
control applications in the automotive and industrial world.
