The fully programmable External Bus Interface provides a direct connection to off-chip memory in as fast as one clock
cycle for a read or write operation. An eight-level priority vectored interrupt controller in conjunction with the peripheral data
controller significantly improve the real-time performance of the device.
The device is manufactured using Atmel’s high-density CMOS technology. By combining the ARM7TDMI processor core
with an on-chip SRAM, a wide range of peripheral functions, analog interfaces and low-power oscillators on a monolithic
chip, the Atmel AT91M55800A is a powerful microcontroller that provides a highly-flexible and cost-effective solution to
many ultra low-power applications.
