AT91M55800A-33AU

Product Summary

The AT91M55800A-33AU 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. The AT91M55800A-33AU 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 AT91M55800A-33AU is a powerful microcontroller that provides a highly-flexible and cost-effective solution to many ultra low-power applications.
