Hardware Specification

110120-1000A

Non-volatile Memory

Non-volatile memory included on the GCM supports application data storage and a real-

time clock function.

Flash Memory

Flash memory is the primary site for non-volatile data storage on the GCM. The standard

configuration is 128 MB. Up to 1 GB is available as a volume production option.

Eurotech systems store the operating system, applications, and system configuration

settings in the on-board flash. Most operating systems configure a portion of the flash as

a flash disk, which acts like a hard disk drive.

Real-Time Clock

The GCM uses a real-time clock (RTC) chip to retain the system date and time when the

system is powered down. For general specifications, see

Real-Time Clock

, page

The operating system typically reads the RTC on boot or on wakeup and sets the RTC

when the system time or date is changed. The PXA320 communicates with the RTC on

the I

C bus. For details about the I

C bus, see

I2C Bus

, page

External Memory

Three types of external memory interfaces provide mass storage options for the GCM: a

CompactFlash socket, two SD/MMC sockets, and up to two USB host ports. This section

describes the three options.

CompactFlash Card

CompactFlash cards provide removable storage in a wide variety of capacities. The

GCM supports Type I and II, 3.3 V cards installed in socket

, page

. This capability

can be a cost-effective means to expand system storage. Normally, the socket is de-

energized. The processor is responsible for turning the socket on when a card is

inserted and turning it off when the card is removed.

SD/MMC Card

You can use a SD/MMC card in socket

J10

, page

or socket

, page

to provide

mass storage on the GCM. For a description of the various modes of operation for the

SD/MMC interface, see

SD/MMC Interface

, page

USB Disk Drive

A USB disk drive can connect to the USB host ports on socket

, page

. Any USB

device that has USB drivers installed on the GCM can connect to this port. For details

about the USB ports, see

USB Ports
