3.1.5 Safety Characteristics

The bare board meets or exceeds the requirements of UL flammability rating 94 V0. The bare board is also marked with the supplier’s name or trademark, type, and UL flammability rating. Since this board is installed in a PCI bus slot, all voltages are below the SELV 42.4 V limit.

3.2 Operational Environment

The LSI21003 is designed for use in PCI computer systems with an ISA/EISA bracket type. The SDMS software operates the board; however, the design of the board does not prevent the use of other software.

An on-board flash memory device is provided to allow BIOS code and open boot code support through the PCI bus and a serial EEPROM for each channel.

3.2.1 The PCI Interface

The PCI interface operates as a 32-bit DMA bus master. The connection is made through edge connector J1, which provides connections on both the front and back of the board. The signal definitions and pin numbers conform to the PCI Local Bus Specification Revision 2.2 standard. The signal assignments appear in Tables 3.2 and 3.3.

Note: The +3.3 V pins are tied together and decoupled with high frequency bypass capacitors to ground. No current from these 3.3 V pins is used on the board. The PCI portion of the LSI53C1010 is powered by 3.3 volts from the on-board regulator.
