S3C2440AL-40

This user's manual describes SAMSUNG's S3C2440AL-40 RISC microprocessor. SAMSUNG's S3C2440AL-40 is designed to provide hand-held devices and general applications with low-power, and high-performance microcontroller solution in small die size. To reduce total system cost, the S3C2440AL-40 includes the following components.

The S3C2440AL-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 Architecture (AMBA).The S3C2440AL-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.

The S3C2440AL-40 has six features.(1)integrated system for hand-held devices and general embedded applications.(2)16/32-Bit RISC architecture and powerful instruction set with ARM920T CPU core.(3)enhanced ARM architecture MMU to support WinCE, EPOC 32 and Linux.(4)instruction cache, data cache, write buffer and Physical address TAG RAM to reduce the effect of main memory bandwidth and latency on performance.(5)ARM920T CPU core supports the ARM debug architecture.(6)internal Advanced Microcontroller Bus Architecture (AMBA) (AMBA2.0, AHB/APB).
