This user’s manual describes SAMSUNG's S3C2440A 16/32-bit RISC microprocessor. SAMSUNG’s S3C2440A isdesigned to provide hand-held devices and general applications with low-power, and high-performance microcontrollersolution 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. Itadopts 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 byAdvanced RISC Machines, Ltd. The ARM920T implements MMU, AMBA BUS, and Harvard cache architecturewith 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 andeliminates the need to configure additional components. The integrated on-chip functions that are described in thisdocument include:
