STS-ISA855 INDUSTRIAL MOTHERBOARD

STS-ISA855 INDUSTRIAL MOTHERBOARD

1 Introduction

The IA-855 is a low-power, single 12V power board with an Intel 855GM chipset, with the following key features.

1.1 Key features

1.1.1 CPU: Celeron M or Pentium M, FPGA479 on board
1.1.2 Memory, on-board 512MB or 256MB
1.1.3 Northbridge is available at Intel 855GM/852GM, and Southbridge ICH4M/ICH4
1.1.4 The chipset integrates the VGA card (CRT DB15 interface)
1.1.5 Supports storage for CF, IDF-44, IDF-40, SATA multiple interfaces
1.1.6 Supports 2 RS232 serial ports
1.1.7 Supports 1 x 10M LAN
1.1.8 Supports 5 USB ports
1.1.9 Support for AC97
1.1.10 Support parallel
1.1.11 Support s/2
1.1.12 Supports dual-channel 24-bit LVDS screens (optional)

1.2 Power

Single-input direct circulation power supply, DC12V (−5%), can be used in ATX switch machine mode and automatic power-on mode.

The input supply voltage directly affects the 12V power supply of the motherboard output, and the input voltage deviation is large, which can endanger the power of hard drive and extra card from the motherboard.

1.3 Structure

240 × 180 mm

1.4 Working environment

• Motherboard operating temperature: −10°C to +60°C

• Motherboard storage temperature: −40°C to +85°C
