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 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.
