[quote="Bean (Hitt Consulting)"]Guenther,
I was thinking /MCLR could be tied high inside the package. That would give 4 I/O pins. But as you pointed out that would be very mimimalistic.
What I'd really like to see is the SX48/52 die in a DIP package. The SX48/52 has twice the RAM and twice the program memory, not to mention the other features.
Unless your connecting to a parallal RAM chip, I rarely see a need for 40 I/O pins.
 

I realize this is all just "pie-in-the-sky" as it will take Parallax awhile just to get "up to speed" with the existing packages.

Bean,

yes, you are right - /MCLR could be tied to Vdd internally, although I sometimes have needed it in systems with slow rising power supplys.

I absolutely agree with you - it would be really attractive having an "SX48/28AC", the "large" die in a DIP28 package. Same number of I/O pins but twice the RAM and twice the program memory plus two 16-bit multi-purpose counter/timers. Imagine - this would allow you to "boost-up" existing hardware by just replacing the "old" SX28AC with the new pin-compatible "Power SX28". Some of my "commercial" SX28-based applications come close to the SX28's memory limits, and customers always want more, so I'd "love" the SX28/48AC". I'll put it on my wish list I'm going to send Parallax for next Christmas :-) .
