I just noticed that the SX28 DP's are out of stock and there is no estimated date when they will be back in stock.  Anyone know when or if they will be back?  I sell a product that uses these and I only have 5 left :(

I'm sure the SX's will be back in stock...but you should know (if you didn't already) the SX is a EOL product (End Of Life).

They are going to stop producing the SX. You may want to start a redesign now.....to handle when the SX is gone.

Parallax has stated they are going to buy enough for a couple of years ( I can't remember how long they guesstimated), but if it were me, I wouldn't take any chances.

That way when the SX's are gone, you just switch over to your new design......

I can't say if you could have a direct replacement, but there are many chips you could probably redesign with. I guess it just depends on what it does, and how much programming it would take for a new chip to do the same thing.

There are lots and lots of 16 to 20 pin PICs and AVRs out there that would work.  You'd have to buy a new programmer and there are some free to inexpensive programming tools.  I used to use a PIC12F683 for an 8-pin device and a PIC16F690 for a 20-pin device.  Both are supported by the PicKit2 programmer and you can use PICbasic (not free, but cheap) to program it (or assembly).

So you need a simple chip which comes in a dip style. You need 16 I/O, and simple to program. What about calculation speed?

I don't know of any, but if you get the specifications out there...someone may be able to recommend a chip.

The Spin Stamp might work for you at $40 in 20 quantities.  It uses the Propeller which will be around for a long time.  It's a 24-pin through hole 0.6" wide module, a little wider than the SX, but it includes a regulator like the Stamps that provides +5V for external use which is further regulated to 3.3V.  Because it's a Propeller, the I/O pins are 3.3V, so you may need to change the button circuitry.  The rest (LED and outputs) should work fine.

The Propeller has plenty of memory for variables while it's running.  It shares 32K between the running program and its variables, but this is SRAM.  Its contents goes away when the power goes off.  The Propeller copies the program from the EEPROM to the SRAM when it's reset like on power up.  When you download a new program using the development environment (the Propeller Tool), it gets copied to the EEPROM by the Propeller.

I'm not sure of the memory requirements, for i haven't compared the two.  Just for information, the Propeller runs on 3.3 volts not 5 volts.

I thought that may be important to your considerations.

Technically, you'll have more space -- you have eight cogs each with 2K (bytes).  Now, cog memory is broken into longs (four bytes) so you only have 512 per cog but still, you have a total of 4K longs inside the Propeller.

Don't worry about the reduction in instructions within a cog -- PASM is far more powerful than SX assembly.  Give the Propeller  a try; you'll find that integrating code written by others is simpler.

Don't get wrapped around the axle (pun intended, as you do automotive projects) with the term "cog" -- it's a fancy term for processor.  In your dual-SX system you have to establish a communication link with wires and a protocol.  It's much easier going cog-to-cog: you simply define a section of hub RAM (main, 32K) that both cogs know about and can exchange information.  You could, for example, have a cog devoted to monitoring a sensor; it can write the sensor value to the hub were that value can be picked up by another cog that is maintaining a display.  
Yes, it takes a little time getting used to, but once you do you'll find that you can do advanced things more easily in the Propeller than in the SX (my opinion, not looking to start a war here).  I use the SX and Propeller every day and on a big SX-based animatronics control project I delivered a couple of weeks ago kept thinking, "Man, I wish this controller had Propeller on it."
