Product Overview

The AT91M55800A-33AU is a 32-bit Microcontroller 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 registers result in very fast exception handling, making the device ideal for real-time control applications. 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.
