DESCRIPTION
The MitySOM-1808 is a highly configurable, very small form-factor processor card that
features a Texas Instruments AM1808 456 MHz ARM Applications Processor, FLASH
(NAND, and NOR) and mDDR2 RAM memory subsystems. The MitySOM-1808
provides a complete and flexible CPU infrastructure necessary for the most demanding
embedded applications development.
The AM1808 includes an ARM926EJ-S micro-processor unit (MPU) capable of running
the rich software applications programming interfaces (APIs) expected by modern system
designers. The ARM architecture supports several operating systems, including Linux,
QNX and Windows XP embedded. Linux drivers are available for all interfaces.

Figure 1 MitySOM-1808 Block Diagram
Figure 1 provides a top level block diagram of the MitySOM-1808 processor card. As
shown in the figure, the primary interface to the MitySOM-1808 is through a standard
SO-DIMM-200 card edge interface. The interface provides power, synchronous serial
connectivity, and a rich set of interfaces available for application defined interfacing.
Details of the SO-DIMM-200 connector interface are included in the SO-DIMM-200
Interface Description, below.
AM1808 mDDR2 Memory Interface
The AM1808 includes a dedicated DDR2 SDRAM memory interface. The MitySOM1808 includes up to 256 MB of mDDR2 RAM integrated with the AM1808 processor.
The bus interface is capable of burst transfer rates of 600 MB / second. Note that the
OSCIN frequency to the AM1808 processor on the module is 24MHz.
AM1808 SPI NOR FLASH Interface
The MitySOM-1808 includes 8 MB of SPI NOR FLASH. This FLASH memory is
intended to store a factory provided bootloader, and typically a compressed image of a
Linux kernel for the ARM core processor.

EMIFA / NAND FLASH Interface
The Asynchronous External Memory Interface (EMIFA) interface available on the
AM1808 is available on the SO-DIMM-200 connector. The EMIFA interface includes 3
chip select spaces. The EMIF interface supports multiple data width transfers and bus
wait state configurations based on chip select space. 8, and 16 bit data word sizes may be
used.
Up to 512 MB of on-board NAND FLASH memory is connected to the AM1808 using
the EMIFA bus. The FLASH memory is 8 bits wide and is connected to the third chip
select line of the EMIFA (CE1). The FLASH memory is typically used to store the
following types of data:
- ARM Linux / Windows Embedded CE / QNX embedded root file-system
- runtime ARM software
- runtime application data (non-volatile storage)
AM1808 Camera and Video Interfaces
The AM1808 includes an optional video port I/O interface commonly used to drive LCD
screens as well as a camera input interface. These interfaces have been routed directly to
the SO-DIMM-200 connector.
Debug Interface
The JTAG signals for the AM1808 processor have been brought out to a Hirose header
that is intended for use with an available Critical Link breakout adapter. This header can
be removed for production units; please contact your Critical Link representative for
details.
This adapter is not included with individual modules but is included with each Critical
Link Development Kit that is ordered. If an adapter, Critical Link (CL) part number 80000286, is needed please contact your Critical Link representative.
Software and Application Development Support
Users of the MitySOM-1808 are encouraged to develop applications using the MitySOM1808 software development kit provided by Critical Link LLC. The development kit
includes an implementation of an OpenEmbedded board support package providing an
Angstrom based Linux distribution and compatible gcc compiler tool-chain with
debugger.
Growth Options
The MitySOM-1808 has been designed to support several upgrade options. These options
include various speed grades, memory configurations, and operating temperature
specifications including commercial and industrial temperature ranges. The available
options are listed in the section below containing ordering information. For additional
ordering information and details regarding these options, or to inquire about a particular
configuration not listed below, please contact a Critical Link sales representative.

Description
EMIF-A pins. These pins are direct connects to the
corresponding EMA_* pins on the AM1808 processor.
Alternatively, these pins can be configured as GPIOs for
modules that do not have NAND memory present. For details
please refer to the AM1808 processor specifications. Note that
pins 197, 198, 199 and 200 have 1.00K Ohm resistors in
series with the signals on the module.
Universal Parallel Port pins.
These pins are direct connects to the corresponding UPP_*
pins on the AM1808 processor. The UPP_* function pins are
multiplexed with other functions. These include RMII,
VP_DIN, MMCSD1, and GPIO. For details please refer to
the AM1808 processor specifications.
Reduced Media Independent Interface pins.
These pins are direct connects to the corresponding RMII_*
pins on the AM1808 processor. The RMII_* function pins
are multiplexed with other functions. These include UPP and
VP_DIN. For details please refer to the AM1808 processor
specifications.
Liquid Crystal Display pins.
These pins are direct connects to the corresponding LCD_*
pins on the AM1808 processor. The LCD_* function pins are
multiplexed with other functions. These include VP_DOUT,
UPP, MMCSD1, and GPIO. For details please refer to the
AM1808 processor specifications.
Video Port In/Out.
These pins are direct connects to the corresponding VP_* pins
on the AM1808 processor. The VP_* function pins are
multiplexed with other functions. These include UPP,
MMCSD1, and GPIO. For details please refer to the AM1808
processor specifications.
Reset Output pin.
This pin is a direct connect to the RESET_OUT pin on the
AM1808 processor. This pin can also be configured as a
GPIO. For details please refer to the AM1808 processor
specifications.
Universal Serial Bus 0 / 1 pins.
These pins are direct connects to the corresponding USB_*
pins on the AM1808 processor. For details please refer to the
AM1808 processor specifications.
