Default Altera Cyclone Serial Configuration devices.

I started reading some documents about the configuration
devices EPCS1 & EPCS4. They appear to be programmed with a
new download cable, the Byteblaster2.
The Byteblaster2 claims compatibility with the previous models,
the Byteblaster and the ByteblasterMV. Unfortunately, there
is no schematics included in the Byteblaster2 datasheet.
Is the 74HC244 being changed to a 74LV244 this time ?

Byteblaster2 is a superset of MV -- more than a buffer.
But I expect that the MV can program an EPCS1.

I believe there's an extra pin so the two aren't quite forward compatible.

A link to the schemtaic for the ByteBlaster II was posted on this site
a while back !!

Thanks.
I have all messages 3 month back and was to find it.
One paper claims to redo BBMV into BB2, but without 1.5V.
The other, ...
I'll have a look at them anyway.

-- Hi

BB2 MUST be used to configure both EPCS1 and EPCS4 using the AS scheme.

Cheers,

Rich.
