Description
The AT91M40800 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 AT91M40800 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 an on-chip high-speed memory and a wide
range of peripheral functions on a monolithic chip, the AT91M40800 is a powerful
microcontroller that offers a flexible, cost-effective solution to many compute-intensive
embedded control applications.
