UC-7122/7124 User’s Manual Introduction
Overview
The UC-7122/7124 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-7122/7124 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-7122/7124 with a powerful computing engine
and communication functions, but without generating too much heat. Moreover, the built-in 16
MB NOR Flash ROM and 32 MB SDRAM give you enough storage capacity to run applications
on the UC-7122/7124. The additional SD socket provides the flexibility for storage expansion, and
the dual LAN ports built into the ARM9 make the UC-7122/7124 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-7122/7124 embedded computers are convenient and powerful central control units for
industrial applications, such as data acquisition, remote device control and monitoring, and
protocol conversion.
