Introduction
Product Description
The MB890 Mini ITX board incorporates the Intel
®
advanced 855GME Chipset
that contains two core components: the Memory Controller Hub (GMCH) and
ICH4. The GMCH integrates a 400MHz Pentium
®
M processor front side bus
controller, integrated graphics controller hub, integrated LVDS interface, two
digital video out ports multiplexed with an AGP 4x controller, a 200/266/
333MHz DDR-SDRAM controller.
The ICH4 integrates an Ultra ATA 100/66/33 controller, USB host controller
that supports the USB 1.1 and USB 2.0 specification, LPC interface, FWH Flash
BIOS interface controller, AC’97 digital controller and a hub interface for
communication with the GMCH.
The Pentium M processor is a higher performance, lower power processor with
several microarchitectural enhancements over existing Intel low-power
processors. Some key features of the Pentium M processor microarchitecture
include dynamic execution, data pre-fetch logic, 400MHz source-synchronous
Front Side Bus (FSB), on-die 1 Mbyte second level cache (on-die 512Kbyte
second level cache on Celeron M processor) with advanced transfer cache
architecture, streaming SIMD extensions 2 (SSE2), and Enhanced Intel
SpeedStep technology.
The super I/O W83627THF onboard integrates the following major peripheral
functions in a chip: the disk driver adapter (FDC), serial port (UART), parallel
port (SPP/EPP/ECP), keyboard controller (KBC), SIR, game port, MIDI port,
hardware monitor, ACPI and On Now Wake-up features.
MB890 supports both DVI and optional TV-OUT with the use of the Chrontel
CH7009 (default) or support DVI only with the use of the Chrontel CH7301. The
TV-Out processor performs non-interlace to interlace conversion with scaling
and flicker filters, and encodes the data into any of the NTSC or PAL video
standards.
The MB890 Mini-ITX motherboard supports CRT VGA interface as well. Intel
82541GI supports Gigabit Ethernet functionality. The board also has AC97
5.1CH audio, 2 COM ports, UDMA 100, 6 USB ports, watchdog timer and a PCI
slot for expandability. Dimensions of the board are 170mm x 170mm.
Note: MB890 uses 852GM and MB890F uses 855GME chipset.
