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 audio codec interface, IIC-BUS interface, IIS-BUS interface, USB host, USB device, SD host & multimedia card interface, 2-ch SPI and PLL for clock generation.
