CoreModule/486-II

Ultra-compact PC/AT-compatible, stackable module

Includes all PC/AT motherboard functions: 
Powerful 50 MHz CMOS 486SLC-2 CPU
Up to 16M bytes onboard DRAM
16-bit expansion bus

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

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

 Very low power consumption (4.7 watts)

 Stackable PC/104 expansion

The CoreModule/486-II offers complete
PC/AT compatibility in a compact,
preconfigured module. Within just
14 square inches of space, the
CoreModule/486-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 50 MHz 486SLC-2
CPU, along with hardware and software
standards like PC/AT and MS-DOS
compatibility.

The CoreModule/486-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/486-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
board.

*Solid State Disk Reliability*
One of the unique features of the
CoreModule/486-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,
y DOS-based-softwareÑincluding the
operating system, programming
languages, drivers, and application
ogramsÑcan easily be run from SSD
without modification.

*Enhanced BIOS*
Another very important feature of the
CoreModule/486-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.

floppy drives: SSDs may coexist with standard
floppy and/or hard disk drives

 SCSI services: supports DOS-based system
operation using a wide variety of SCSI drives:
adds a unique SCSI/BIOS function to simplify
development of custom SCSI applications;
SCSI and IDE hard disks may coexist

 Watchdog timer support: initilizes optional
onboard watchdog timer; adds BIOS function
for use by application software

 Serial console option: substitutes an ASCII
terminal or other serially-connected device for
the standard AT keyboard and display

 Battery-free boot: allows the system to boot
and operate without a battery (or when the
battery fails)

 Serial loader: allows download of executable
code from a remote device prior to system boot

 EEPROM access function: provides high level
access to the 512-bit nonvolatile OEM data area
in the configuration EEPROM

 OEM "hooks": execute custom code prior to
