The AT91M55800A is a member of the Atmel AT91 16/32-bit microcontroller 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 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. 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 costeffective solution to many ultra low-power applications.
