Product Summary

The SAMSUNG S3C2440A40-YQ80 16/32-bit RISC microprocessor is designed to provide hand-held devices and general applications with low-power, and high-performance microcontroller solution in small die size. The S3C2440A40-YQ80 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 Architecture (AMBA). The S3C2440A40-YQ80 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.
