CPU-1440 Dev Kit user manual

Ethernet
A 10/100 Ethernet interface (MAC and PHY) is available on the CPU-1440 board,
implemented in the Vortex86DX processor. It provides a standard IEEE 802.3 Ethernet
interface for 100BASE-TX and 10BASE-T applications (802.3, 802.3u). Magnetics are
included.
IDE support
The CPU-1440 breakout board provides a single primary IDE controller, with a 44-way
2mm header (J27) to connect one or two external IDE devices.
This gives the user the possibility to connect an external hard drive or CD-drive to the
CPU-1440 board. A jumper W2 is used to configure the Compact flash socket support
in master mode or slave mode. If you want to use an external hard drive you have to
select slave mode for the Compact flash socket.
The BIOS detects the IDE devices during the POST processes and configures the
hardware correctly. The BIOS allows either a master or a slave device to be the boot
device. It also allows the manual selection of transfer modes (Fast PIO, and up to
UDMA-2).
A LED is present on the CPU-1440-Breakout and signals access to the IDE bus.
SPI Flash Drive
The CPU-1440 board integrates a 2MB bootable SPI flash drive. It is recognized by the
BIOS and can be used to store a small DOS application. By default, a DOS 6.22
version is installed on the SPI Flash Drive. For that the BIOS must be well configured.
PS/2 interface
Legacy PS/2 keyboard and mouse are supported on standard PC99 MiniDin
connectors.
Serial ports
The CPU-1440 provides four 16C550-compatible serial ports. It supports up to
115Kbaud data rates and 16-byte send/receive FIFO’s. RS-485 auto-direction flow
control is supported on COM3 and COM4.
Touchscreen controller
The CPU-1440 development kit supports the Eurotech’s TSC1. The TSC1 is an
analogue resistive touchscreen controller that interfaces with the processor board via
an RS232 serial port.
