General Description

The Little Board P6d system is a high integration, high-performance Pentium- II based PC/AT-

compatible system that conforms to the EBX V1.1 specification. This rugged and high qu ality

single-board system contains all the component subsystems of a PC/AT PCI motherboard plus the

equivalent of up to six expansion boards. The Little Board P6d system meets the size, power

consumption, temperature range, quality, and reliability demands of embedd ed syste m applicatio ns.

Key functions on the Little Board P6d module include:

– High-speed Pentium-II CPU

– 64-bit wide 3.3V SDRAM - up to 256MB

– 256KB Internal secondary cache

– Embedded-PC BIOS in Flash EPROM

– Four buffered serial ports (with RS232,

RS485, TTL options)

– Two universal serial bus (USB) ports

– Infrared (IrDA) port

– Multi-mode IEEE-1284 parallel port

– Floppy controller

– Dual PCI-bus EIDE/UltraDMA drive

controllers

– Flat panel/CRT display controller

– Sound Blaster Audio

– Ethernet 100BaseT LAN interface,

– CompactFlash solid-state IDE drive

support

– Standard PS/2 Keyboard/Mouse and

speaker interfaces

In addition, Ampro has made many improvements to the architecture and firmware of the

traditional desktop PC to optimize it for embedded applications. Among the many embedded-PC

enhancements that ensure fail-safe embedded system op eration and app lication v ersatility are a

watchdog timer, a powerfail NMI generator, serial console support, serial boot loader, non-battery

boot, failsafe boot, accelerated boot, on-board high-density CompactFlash disk, and BIOS extensions

for OEM boot customization.

System operation requires a single +5 Volt power source (and 3.3 Volts for low-v oltage PCI

expansion cards, if required) and offers "green PC" power-saving modes under support of Advanced

Power Management (APM) BIOS functions.

Product Feature Summary

CPU/Motherboard

The Little Board P6d module has a fully compatible PC architecture, with a Pentium-II low-voltage

CPU.

For improved reliability in harsh thermal environments, the board implements a CPU the rmal

sensor and configurable thermal-management control logic in the BIOS.
