Introduction

Product Description

The MB870 Pentium 4 Mini ITX board incorporates the ATI RS300M

chipset and supports 478-pin Intel Pentium 4 processors of 2GHz and up

to 3.2GHz+ with FSB 800MHz/533MHz/400MHz. MB870 supports the

Pentium 4 processor with 256-KB L2 cache, Pentium 4 processor with

512-KB L2 cache on 0.13 micron process.

The I/O functions are on MB870 integrated onto the IXP150. It supports

the integrated graphics processor (IGP) on the IGP9180. The IGP has

3D, 2D, and video capabilities. The system memory size can be up to

1GB, using the single DDR socket on board. Four USB ports are

supported with the USB 1.1/2.0 standard.

MB870 supports TV out and LVDS with the use of the ATI RS300M

integrated graphics device that accepts two digital graphics input data

streams. One data stream outputs through an LVDS transmitter to an

LCD panel, while the other data stream is encoded for NTSC or PAL TV

and outputs through a 10-bit high speed DAC. The TV encoder device

encodes a graphics signal up to 1024x768 resolution and outputs the

video signals according to NTSC or PAL standards. The LVDS function

supports 18 bit single and dual channel LCD panels.

*The board does not support 24-bit single and dual channel LCD

panels.

The MB870 Mini ITX SBC supports CRT VGA interface as well as TV

out and LVDS interface. Realtek LAN 8100BL supports Ethernet

functionality (10/100Mb). The board also has AC97 6CH audio, 4 COM

ports, UDMA 100, 4 USB ports, two serial ATA ports, watchdog timer

and a PCI slot for expandability. Dimensions of the board are 170mm x

170mm.

This board represents the perfect choice for those who want superior

performance for POS, kiosk, ATM, Web payphone, medical and other

embedded applications.

Installing the CPU

The MB870 embedded board supports a Socket 478 processor socket for

Intel Pentium 4 processors.

The Socket 478 processor socket comes with a lever to secure the

processor. Raise this lever to about a 90°angle to allow the insertion of

the processor. Place the processor into the socket by making sure the

notch on the corner of the CPU corresponds with the notch on the inside

of the socket. Once the processor has slide into the socket, return the

lever to the lock position. Refer to the figures below.

After you have installed the processor into the socket, check if the

jumpers for the CPU type and speed are correct.

NOTE: Ensure that the CPU heat sink and the CPU top surface are in

total contact to avoid CPU overheating problem that would

cause your system to hang or be unstable.
