2440 datasheet下载

This user’s manual describes SAMSUNG's S3C2440A 16/32-bit RISC microprocessor. SAMSUNG’s S3C2440A 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 S3C2440A includes the following components.
The S3C2440A 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 S3C2440A 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.
By providing a complete set of common system peripherals, the S3C2440A minimizes overall system costs and
eliminates the need to configure additional components. The integrated on-chip functions that are described in this
document include:
