CoreModule 420

Chapter 2 Product Overview

This introduction presents general information about the PC/104 architecture and the CoreModule 420 single board computer (SBC). After reading this chapter you should understand:

•PC/104 Concept

•CoreModule 420 architecture

•CoreModule 420 features

•Major components

•Connectors

•Specifications

PC/104 Architecture

The PC/104 architecture affords a great deal of flexibility in system design. You can build a simple system using only a CoreModule 420, with input/output devices connected to its serial or parallel ports, and a solid state disk drive or CompactFlash card in the respective bytewide socket, or CompactFlash socket. To expand a simple CoreModule system, simply add self-stacking Ampro MiniModules or 3rd party PC/104 expansion boards to provide additional capabilities, such as:

•Additional serial and parallel ports

•Analog or digital I/O

•PCMCIA interfaces

•Sound cards

PC/104 expansion modules can be stacked with the CoreModule 420 avoiding the need for card cages and backplanes. The PC/104 expansion modules can be mounted directly to the PC/104 bus connector of the CoreModule 420. PC/104-compliant modules can be stacked with an inter-board spacing of ~0.66 inches so that a 3-module system fits in a 3.6 inch by 3.8 inch by 2.4 inch space. See Figure 2-1.

One or more MiniModule products or other PC/104 modules can be installed on the CoreModule expansion connectors. When installed on P1 and P2, the expansion modules fit within the CoreModule outline dimensions. Most MiniModule products have stack through connectors compatible with the PC/104 Version 2.5 specification. Several modules can be stacked on the CoreModule headers. Each additional module increases the thickness of the package by 15mm (0.60”). See Figure 2-1.

Product Overview

Product Description

The CoreModule 420 SBC is an exceptionally high integration, high-performance, 486-based PC compatible system in the PC/104 form factor. This rugged and high quality single board system contains all the component subsystems of a PC/AT motherboard plus the equivalent of several PC/AT expansion boards.

In addition, the CoreModule 420 SBC includes a comprehensive set of system extensions and enhancements that are specifically designed for embedded systems. These enhancements ensure failsafe embedded system operation, such as, a watchdog timer. It is designed to meet the size, power consumption, temperature range, quality, and reliability demands of embedded applications. The CoreModule 420 requires a single +5V power source.

The CoreModule 420 SBC is particularly well suited to either embedded or portable applications. Its flexibility makes system design quick and easy. It can be stacked with Ampro MiniModules or other PC/104-compliant expansion, or it can be used as the computing engine in a fully customized application.

LED Definitions

Table 2-4 provides the LED color and definitions for the Ethernet Port (J2) located on the CoreModule 420 and Figure 2-5 provides the locations.

Table 2-4. Ethernet Port (J2) LED Indicators

Indicator	Definition
Ethernet	Link/Activity LED – This yellow LED is the activity/link
Link/Activity LED (D1)	indicator and provides the status of Ethernet port (J2).
	The Link/Activity LED indicates an Link is established with
	either transmit or receive activity.
	Yellow On – This indicates a link is present.
	Yellow Flashing – This indicates activity is present.
	Yellow Off – This indicates no link or activity is present.
Ethernet Speed (D2)	Speed LED – This green LED is the LAN Speed indictor and
	indicates the transmit or receive speed of Ethernet port (J2).
	Green On – This indicates the operating speed is 100Mbps
	Green Off – This indicates the operating speed is 10Mbps.

Chapter 2 Product Overview

NOTE	The CoreModule 420 is in violation of the PC/104 height limitations in two
	places on the bottom of the board. The voltage regulator (U19) exceeds the
	allowed height limitation by 0.085 inches and the CompactFlash socket (J12)
	exceeds the height limitation by 0.2 inches. See Figure 2-6.

Power Specifications

Table 2-6 provides the power requirements.
