The S3C2400 was developed using an ARM920T core, 0.18um CMOS standard cells and a memory complier. Its low-power, simple, elegant and fully static design is particularly suitable for cost-sensitive and power sensitive applications. Also S3C2400 adopts a new bus architecture, AMBA (Advanced Microcontroller Bus Architecture) An outstanding feature of the S3C2400 is its CPU core, a 16/32-bit ARM920T RISC processor designed by Advanced RISC Machines, Ltd. The ARM920T implements MMU, AMBA BUS, and Harvard cache architecture with separate 16KB instruction and 16KB data caches, each with a 8-word line length. By providing complete set of common system peripherals, the S3C2400 minimizes overall system costs and eliminates the need to configure additional components. The integrated on-chip functions that are described in this document include:
