Product Summary

The S3C2440AH-40 is a 32-bit CMOS microprocessor, designed to provide hand-held devices and general applications with low power, and high-performance microcontroller solution in small die size. The S3C2440AH-40 is developed with ARM920T core, 0.13um CMOS standard cells and a memory complier. Its lowpower, simple, elegant and fully static design is particularly suitable for cost and power-sensitive applications. It adopts a new bus architecture known as Advanced Micro controller Bus Architectur (AMBA). The S3C2440AH-40 offers outstanding features with 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 an 8-word line length.
