Considering sh2-7044 very old, I think it is an error for the following=20
reason: it is 5V supplied, insted of being 3.3V supplied.=20
We disovered that 3.3 V is not so suitable around each application=20
environment, so that 5V devices are still ther dignity, even if ther seen t=
o=20
be old are birth age.
Among all the sh-2 Renesas' devices 5V devices are not so mach, so 7044 and=
=20
its 5V childern I think are still interesting.

Anyway now I have 1 Mbyte ram Board 7045 based, and not much ram is availab=
le=20
on all the board made by me; I don't know if 1MByte of ram is enough.

Ciao and best regards.

P.S.

What are you working on at this  moment?
