    Hi all,

    I've a question for anyone out there that has done designs with the
    Winbond chips. I wish to use a ISD11X0 in a design that wants to have
    multiple phrases that are uttered in round-robin format. What I have
    been unable to ascertain is whether the ISD1110 can be addressed like
    the ISD1420 chip, to get selection and fast-forwarding of arbitrary
    length messages (not needing specific addresses to be used.) Can anyone
    shed light on this? I want to use the cheapest chip possible in the
    design. <surprise>

    Also, is the on chip speaker amp good enough to be heard with a 1"
    diameter 16 ohm speaker at close range in a not terribly noisy room?
    Any information that anyone has would be appreciated before I started
    on a client project and brought in parts.

    thanks,
    DLC
