Product Summary

The AM1808B is a Low-power applications processor based on ARM926EJ-S. The device enables OEMs and ODMs to quickly bring to market devices featuring robust operating systems support, rich user interfaces, and high processing performance life through the maximum flexibility of a fully integrated mixed processor solution. The AM1808B is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions and processes 32-bit, 16-bit, or 8-bit data. The AM1808B core uses pipelining so that all parts of the processor and memory system can operate continuously.
