Overview
UC-7112/UC-7110 Mini RISC-based Communication Platforms are
ideal for your embedded applications. UC-7112/UC-7110 comes
with two RS-232/422/485 serial ports and dual 10/100 Mbps
Ethernet LAN ports to provide users with a versatile communication
platform.
UC-7112/UC-7110 uses the ARM9 RISC CPU. Unlike the X86 CPU,
which uses a CISC design, the ARM9’s RISC design architecture
and modern semiconductor technology provide UC-7112/UC-
7110 with a powerful computing engine and communication
functions, but without generating too much heat. The built-in 8
MB NOR Flash ROM and 16 MB SDRAM give you enough storage
capacity, and an additional SD socket provides the user with flexible
storage expansion to run applications. The dual LAN ports built
into the ARM9 make UC-7112/UC-7110 an ideal communication
platform for some of the more simple data acquisition and protocol
conversion applications, and the two RS-232/422/485 serial ports
allow you to connect a variety of serial devices.
The pre-installed μClinux operating system provides an open
software operating system for software program development.
This means that software written for desktop PCs is easily ported
to UC-7112/UC-7110 by using a GNU cross complier, so that you
will not need to spend time modifying existing software code. The
operating system, device drivers, and your own software can all be
stored in the UC-7112/UC-7110’s Flash memory.
