Description
The SBC440-II is a single board computer (SBC) powered by Samsung S3C2440 processor
operating at 400MHz designed by Samsung. The 16/32-bit RISC microprocessor has addi-
tional a complete set of common system
peripherals including LCD controller (STN & TFT), System Manager (chip select logic and
SDRAM controller), 3-ch UART, 4-ch DMA, I/O ports, RTC, 8-ch 10-bit ADC and touch
screen interface, IIC-BUS interface, IIS-BUS interface, USB host, USB device, SD host &
Camera interface, 2-ch SPI and PLL for clock generation.
The board takes full advantage of the S3C2440A microcontroller.
Because of its small size and low power consumption, it is well suited for
portable and mobile products. It supports a variety of onboard peripherals such as 64Mbyte
Nand Flash, 64Mbyte SDRAM, USB Host and USB Device, serial ports, Ethernet interface,
camera interface, battery backed RTC, LEDs, reset buttons. In addition to this, expansion
connections are made available via a number of header connectors and support peripheral
LCD hardware, touch screen, SD card, JTAG, system bus and GPIOs.

The SBC 440-II is capable of supporting Linux and WinCE OS. Default provided is Linux 2.6.13
source code and WinCE4.2/5.0 BSP with this board, which could help customers better understand the
hardware operations and quicken your development steps.
Digitec offers, as a full-featured Integrated Development Environment (IDE) that can
be used to develop applications, download binaries to the target and debug applications. The
IDE runs from a PC and can be ordered with either a high-speed JTAG interface (up to 800kbps)
or standard interface (120kbps). Optional LCD display hardware is also available for this
development board and can be easily connected to an existing header.
Hardware Features
The S3C2440A processor features an ARM920T core, a 16/32-bit RISC microprocessor for
high performance in a small form-factor and a low core voltage of 1.3V with a typical power
usage of 0.2W at 400MHz operating speeds. In addition, it is developed using 0.13um CMOS
standard cell and a memory compiler and adopts Advanced Microcontroller Bus Architecture
(AMBA). It has additional a complete set of common system peripherals including LCD
controller (STN & TFT), System Manager (chip select logic and SDRAM controller), 3-ch UART,
4-ch DMA, I/O ports, RTC, 8-ch 10-bit ADC and touch screen interface, IIC-BUS interface,
IIS-BUS interface, USB host, USB device, SD host & Camera interface, 2-ch SPI and PLL for
clock generation.
