      S3C2440 概述

      S3C2440 is a derivative product of Samsung's S3C24XXX family of microprocessors for mobile communication market. The S3C2440 / S3C2440A / S3C2440A-40's main enhancement over the baseline product, S3C2410X, is the addition of camera interface for multimedia messaging services.

      The S3C2440 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 S3C2440 / S3C2440A / S3C2440A-40 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 S3C2440 / S3C2440A minimizes the overall system costs and eliminates the need to configure additional components. The S3C2440 / S3C2440A / S3C2440A-40 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.
