S3C2440处理器是Samsung公司基于ARM公司的ARM920T处理器核，S3C2440是一款高度集成的芯片，这是目前世界上主频最快的嵌入式移动CPU，内核速度为533MHz，内核电压为1.3V，采用16/32位 ARM920T RISC核心，提供的接口支持：数码摄像头、TFT/STN液晶屏、USB、HOST/DEVICE、IIS音频、NAMD闪存、SD/MMC/SDIO存储卡以及触摸屏等。该产品采用0.13微米制成的CMOS处理器。
S3C2440X is a derivative product of Samsung's S3C24XXX family of microprocessors for mobile communication market. The S3C2440X's main enhancement over the baseline product, S3C2410X, is the addition of camera interface for multimedia messaging services。
The S3C2440X features an ARM920T core, a 16/32-bit RISC microprocessor, to provide hand-held devices and general applications with cost-effective, low-power, and high performance micro-controller solution in a small form-factor. The S3C2440X is developed using 0.13 um CMOS standard cell and a memory compiler. In addition, it adopts a new bus architecture called Advanced Microcontroller Bus Architecture (AMBA).。
By providing a comprehensive set of common system peripherals, the S3C2440X minimizes the overall system costs and eliminates the need to configure additional components. The S3C2440 includes the following components: separate 16 KB instruction and 16 KB data cache, MMU to handle virtual memory management, TFT& STN LCD controller, NAND flash boot loader, system manager (chip select logic and SDRAM controller), 3-ch UART, 4-ch DMA, 4-ch timers with PWM, I/O ports, RTC, 8-ch 10-bit ADC and touch screen interface, camera interface, AC97 audiocodec interface, IIC-BUS interface, IIS-BUS interface, USB host, USB device, SD host & multimedia card interface, 2-ch SPI and PLL for clock generation.
