[DSP-10] EZKit-Lite

Wed, 13 Feb 2002 09:20:49 -0600

Another thought is that the '2181 is getting "long-in-the-tooth" and AD may be discouraging it's use.  The later models in
the family are packaged differently (I have some of the "ball grid" samples - if I can ever figure a way to "breadboard"
them! ;->) and are only "code compatible" with the low-end EZKit.
