UC-7124/7122
The UC-7124/7122 embedded computers come with 2 or 4
RS-232/422/485 serial ports and dual 10/100 Mbps Ethernet
LAN ports to provide users with a versatile communication
platform, making these RISC-based embedded computers
ideal for your embedded applications.
The UC-7124/7122 embedded computers use the Cirrus
Logic EP9302 ARM9 200 MHz RISC CPU. Unlike the X86
CPU, which uses a CISC design, the ARM9’s RISC design
architecture and modern semiconductor technology provide
the UC-7124/7122 with a powerful computing engine and
communication functions, but without generating too much
heat. Moreover, the built-in 16 MB NOR Flash ROM and
16 MB SDRAM give you enough storage capacity to run
applications on the UC-7124/7122. The additional SD socket
provides the flexibility for storage expansion, and the dual
LAN ports built into the ARM9 make the UC-7124/7122
ideal communication platforms for simple data acquisition
and protocol conversion applications. In addition, the RS-
232/422/485 serial ports allow you to connect a variety of
serial devices. Taken together, these features ensure that the
UC-7124/7122 embedded computers are convenient and
powerful central control units for industrial applications, such
as data acquisition, remote device control and monitoring,
and protocol conversion.
The pre-installed WinCE 5.0 operating system provides a
common Windows-based software operating system for
software program development. This means that software
written in Visual C/C++, VB and .NET for desktop PCs is
easily ported to the UC-7124/7122 by using a general
programming tool such as Microsoft Embedded Visual C++
or Microsoft Visual Studio 2005. You will not need to spend
time modifying existing software code, and the operating
system, device drivers, and your own software can all be
stored in the UC-7124/7122’s Flash memory.
