System Hardware
Central Processing Unit
The CPU is a 806 MHz Marvell PXA-320 CPU. The operating system is Microsoft® Windows® CE 5. The OS image is stored
on an internal SD flash card and is loaded into DRAM for execution.
Turbo mode switching is supported and turned on by default.
The MX9 supports the following I/O components of the core logic:
l One serial port (DTE) with appropriate power for a WAN radio
l One serial port (DTE) for an integrated laser decoder with RI
l USB 1.1 Host (capable) with power (5V @ 500mA)
l One SSP port (capable)
l One SDIO port for I/O expansion (capable)
l One SIM port for WAN
l One serial port (DTE) for interface with GPS receiver chip
l Non-decoding imager
System Memory
The MX9 supports 128 MB on-board RAM and 128 MB on-board Flash. Operating system and boot loader software image
update is supported via expansion card and remote management via radio.
Internal flash is used for boot loader code and system low-level diagnostics code. Bootloader code is validated at system
startup. The UUID required by CE 5.0 is stored in the boot flash. A second copy of the bootloader code is stored on the internal
SD Flash drive, so that if a damaged bootloader is detected, it may be re-flashed correctly.
Internal SD Memory Card
The MX9 has one SD card interface for storage of operating system and program code, as well as persistent storage.
The internal SD flash card appears to the OS as a folder. This allows the contents to be manipulated via the standard Windows
interface.
