Features and Benefits

  • Cirrus Logic EP9302 ARM9 32-bit 200 MHz processor  RISC computer solution brochure
  • On-board 32 MB RAM, 16 MB flash disk
  • 2 or 4 software-selectable RS-232/422/485 serial ports
  • 50 bps to 921.6 kbps baudrate (nonstandard baudrates supported) 
  • Dual 10/100 Mbps Ethernet for network redundancy
  • SD socket for storage expansion supported 
  • Built-in real-time clock (RTC), buzzer, watchdog timer (WDT)
  • Ready-to-run WinCE 5.0 platform

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 computers. The additional SD socket provides the flexibility of adding storage expansion disks, 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. The RS-232/422/485 serial ports on these computers allow you to connect a variety of serial devices. 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.
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++ for desktop PCs can easily be ported to the UC-7122/7124 computers with 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, the operating system, device or the drivers. You can store the software that you created on the computer’s flash memory without any modification.
