Description

The AT91R40807 microcontroller is a member of the Atmel AT91 16/32-bit microcon-

troller family, which is based on the ARM7TDMI processor core. 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 reg-

isters result in very fast exception handling, making the device ideal for real-time

control applications.

The AT91R40807 microcontroller features a direct connection to off-chip memory,

including Flash, through the fully-programmable External Bus Interface (EBI). 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 Atmel’s high-density CMOS technology. By combin-

ing the ARM7TDMI processor core with a large on-chip high-speed SRAM and a wide

range of peripheral functions on a monolithic chip, the AT91R40807 is a powerful

microcontroller that offers a flexible and high-performance solution to many compute-

intensive embedded control applications.
