S3C2440處理器是Samsung公司基于ARM公司的ARM920T處理器核，S3C2440是一款高度集成的芯片，這是目前世界上主頻快的嵌入式移動CPU，內(nèi)核速度為533MHz，內(nèi)核電壓為1.3V，采用16/32位 ARM920T RISC，提供的接口支持：數(shù)碼攝像頭、TFT/STN液晶屏、U、HOST/DEVICE、IIS音頻、NAMD閃存、SD/MMC/SDIO存儲卡以及觸摸屏等。該產(chǎn)品采用0.13微米制成的CMOS處理器。

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 all 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 (AA).。

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, U host, U device, SD host & multimedia card interface, 2-ch SPI and PLL for clock generation.
