AT91SAM7A1 General Description

AT91SAM7A1 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 AT91SAM7A1 has a direct connection to off-chip memory, including Flash, through the fully-programmable External Bus Interface.

An eight-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 microcontroller core with an on-chip RAM and a wide range of peripheral functions, including USART, SPI, CAN Controllers, Timer Counter and Analog-to-digital Converter, on a monolithic chip, the AT91SAM7A1 is a powerful device that provides a flexible, cost-effective solution to many computeintensive embed-ded control applications in the automotive and industrial world.
