3.2 Operational Environment

The LSI20160 is designed for use in PCI computer systems with a standard bracket type. The SDMS software operates the board, but the design of the board does not prevent the use of other software. An onboard Flash memory device allows you to use BIOS code and open boot code support through PCI and a serial EEPROM.

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 Table 3.2, Table 3.3, and Table 3.4.

Note: The LSI20160 uses 3.3 V pins to run the LSI53C1000 and some other parts. The LSI20160 requires 3.3 V from the PCI + 3.3 V power rail for proper operation.
