144-lead LQFP Package
AT91SAM7A1
The AT91SAM7A1 is a member of the Atmel Smart ARM Microcontrollers product family,
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 8-level priority vectored Interrupt Controller in conjunction with the Peripheral Data Control-
ler 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 RAM and a wide range of peripheral
functions on a monolithic chip, the AT91SAM7A1 is a powerful device that provides a flexible,
cost-effective solution to many compute-intensive embedded control applications in the indus-
trial world.
The AT91SAM7A1 is available in a 144-lead LQFP package.
