- 25 MHz CMOS 386SX CPU
- Up to 16M bytes onboard DRAM
- 16-bit expansion bus

 Other built-in functions
- Dual serial and parallel controller
 Bootable "Solid State Disk"

 Ultra compact PC/104 form-factor:
3.6 x 3.8 inches (90 x 96 mm)

 Low power consumption (3.5 watts)

 Stackable PC/104 expansion

The CoreModule/386-II offers complete
PC/AT compatibility in a compact,
preconfigured module. Within just
14 square inches of space, the
CoreModule/386-II includes the
equivalent functions of a PC/AT
motherboard plus several additional
expansion cards.

Performance-critical embedded
applications that formerly required
chip-based custom designs can now
benefit from an off-the-shelf module
with the power of a 25 MHz 80386SX
CPU, along with hardware and software
standards like PC/AT and MS-DOS

The CoreModule/386-II is designed to
meet the demands of embedded systems.
through its extreme compactness, low
power consumption. +5V-only operation,
wide operating temperature range, and
high reliability.

*Configuration Flexibility*
The CoreModule/386-II can be used as
a macrocomponent, plugged into a
proprietary application board, or it
can be combined with Ampro's PC/104-
compatible MiniModule expansion
products to form compact, highly
integrated control subsystems. Multiple
modules can be stacked together without
the cost and space penalties of additional
mounting hardware, or they can be
separately mounted on a custom circuit

*Solid State Disk Reliability*
One of the unique features of the
CoreModule/386-II is its byte-wide
memory device socket that is typically
used as a Solid State Disk (SSD),
substituting EPROM, Flash EPROM, or
nonvolatile RAM (NOVRAM) memory
devices for conventional disk drives.
Using Ampro's SSD Support Software,
any DOS-based-softwareincluding the
operating system, programming
languages, drivers, and application
programscan easily be run from SSD
without modification.

*Enhanced BIOS*
Another very important feature of the
CoreModule/386-II is its inclusion of
enhanced BIOS services and functions
that meet the unique requirements of
embedded microcomputer system
applications. A partial list of these BIOS
enhancements appears in the
specifications section of this data sheet.
