SPI Explained

The Farnell website has the best explanation of SPI that I've seen in
some time: http://tinyurl.com/2hn7g5

"Parallel SCSI (formally, SCSI Parallel Interface, or SPI) is one of the
interface implementations in the SCSI family. In addition to being a
data bus, SPI is a parallel electrical bus: There is one set of
electrical connections stretching from one end of the SCSI bus to the
other. A SCSI device attaches to the bus but does not interrupt it. Both
ends of the bus must be terminated."

That should make it easy for beginners to interface their E2PROMs!

There is NO connection between SCSI and SPI *WHATEVER*

SPI = serial peripheral interface
SCSI = small computer system interface

Utterly different in about as many ways as you could imagine.

It'll make it fast, in any case...

Check the Wiki entry for SCSI, and you will see the acronym SPI used
to describe exactly what the OP was referring to.

I guess now that SCSI is going SAS they need to come up with a new
abbreviation for the original (parallel) forms of SCSI?

I see it. Was there ever an 'SPI' that meant that ? I've never met it.

In any case the SPI mentioned by Farnell is definitely the serial peripheral
interface type as used by some EEPROMS for example.

Its starting to sound like the morphmister. First it was SASI, then
SCSI,...
