1. Introduction

The UC-7122/7124 Series of mini size RISC-based ready-to-run embedded computers come with the WinCE
operating system pre-installed. The embedded computers have du al 10/100 Mbps Ethernet ports and 2 or 4
RS-232/422/485 serial ports in an ARM9 box. In addition, the UC-7122 and UC-7124 have an internal SD
socket and one USB 2.0 host port for storage expansion, to provide high performance communication and
unlimited storage in a super compact, palm-size box. The UC-7122 and UC-7124 are the right solutions for
embedded applications that use a lot of memory, but that must be housed in a small physical space without
sacrificing performance.

UC-7122/7124 Hardware Introduction

Overview

The UC-7122/7124 embedded computers come with 2 or 4 RS-232/422/485 seri al ports and dual 10/100 Mbps
Ethernet LAN ports to provide users with a versatile communication platform, making thes e 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 funct ions, 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 y ou to connect a variety of serial devic es. Ta ken together, these features
ensure that the UC-7122/712 4 embedded computers are convenient and powerful central control units for
industrial applications, such as data acquisition, remote device control and monitoring, and protocol
conversion.
