Jon revealed this in another forum as an example of posting pictures, it appears there was some conversation that has since been removed for being off topic. So I thought I'd place it in the appropriate forum and provide my comments. Im very impressed Parallax kudos. Its nice to see all our suggestions implemented, the surface mount areas are a very nice touch and the butterfly headers too

    That's really slick Paul. I can't wait to see what will happen to the tools with the release of SX/B 2. I'm guessing we'll see the maturity of the SX28 tools migrate to the SX48/52 pretty quickly. Kudos to the Parallax crew on all the fine work!

    That board looks nice.

    Dave,
    Parallax released SX/B 1.2.x a few days ago and it already includes support for all the SX processors including the SX48 and SX52. You can download it at the sticky message at the top of this forum.

    And if you download the latest version of the SX-Key IDE (3.1 -- recommended) SX/B version 1.2 gets installed.

    Could we please get a socket to program/debug SX48s/52s on these boards?· Pretty please with sugar and ice cream and diabetes on top?

    There is another prototype board being developed for the SX52 (I don't know if it will support the SX48). It will not be a socket but directly soldered to the board since it is a surface mount part, sockets for surface mount components are very expensive (most I have seen are in the $100 price range) this would increase the cost of the board by tenfold.

    The other proto board supports the SX48 or the SX52, and we will solder them to the board for you.

    Well, guess what?! We plan on seeing that you guys buy these right around (or at) our actual cost! This means they'll be in the $10.00 range. We made these boards to make your SX proto projects more fun and we want them to be super low-cost so you can afford to have two or ten of them on-hand.

    Wow, that's a great price point considering the cost of the SX, the fab of the board + components- (granted Parallax does them in bulk, but still)-

    Can't wait!

    Oh, and a suggestion: maybe some board + resonator pack for these......

    Just an observation. The SX28 proto board has the standard 20 I/O ports, and the SX48/52 proto board has 24 I/O ports. So, what would be the reason for going with an SX48/52 proto board, am I missing something here?
  • BeanBean Posts: 8,129
    edited 2005-05-14 14:40
    The SX48 has 36 I/O's and the SX52 has 40 I/O's. Also the SX48/52 has double the program space and double the RAM.

    There are other goodies in the SX48/52 like a couple of timers.

    I was just refering to the protoboard. As I look at the picture of the SX48/52 board, I could be wrong, all I see is 24 I/O pin accessability.

    I·have never·used an SX48/52, but·I see ports RA 0~7, and the same for RB, RC, RD, RE.

    5*8 = 40 I/O pins.....or am I missing something?

    Or maybe you are looking at the wrong post. The pic you are looking at, does it have a ZIF socket? If yes, that is not the SX48/52.

    Sorry, what I do need is a new pair of glasses. The SX48/52 protoboard·is
    starting to look much better, and if it keeps to the $10 price, I think Parallax has a winner.

    I honestly believe you are mis-interpreting enthusiastic anticipation as criticism.

    We will offer a 75MHz crystal separately that will fit in the 4 pin designated area.

    Hey SXers,

    Just checked with our production facility and these boards will be here on the 28th of June. Consistent with our plans, we will offer these at just over our cost. This means the retail price of the SX48 Proto Board (and the SX52 Proto Board) version will be $9.95. This makes no financial sense for Parallax but we think our SXers will be very happy. . . can you imagine how I justify this kind of marketing situation to the financial people who are involved in our business? I'd probably sound like a tongue-tied dope. Not to mention our key distributors - don't know how I'll offer them a discount on this product.

    With the SX48/52 support in the free SX/B compiler you'll have all the tools you need to program this chip (and lots of them, please).

    Sincerely,

    Ken Gracey

    I can't believe you are selling these for $9.95.
    That is pretty aggressive marketing.

    Not being an elctronics engineer, what is the criteria for selecting which board to purchase. Their is a four pin difference, the RA bank, so would the natural instinc be, go with the SX52 proto board, or are their other things to consider?· The choice being between the SX48 and SX52 proto board.

    The SX52 has 40 I/O pins (ports A-E), the SX28 has 20 I/O (Ports B and C and half port A), there are other features that the SX52 has (that the SX28 and below do not have) such as on board timers. Also the SX52 has twice the program memory and data memory than the SX28 has.

    I have a question regarding the SX52 con carne, I know that it was always an under performer as far as sales are concerned. Once you release the protoboard, I predict that your sales of the SX52 con carne will shrivel up like a desert creek. If you decide to discontinue the SX52 con carne, will you release to the public the Gerber files for product? Using sparkfun's PCB service, a duplicate carrier board could be made for $5-$10 (depending if it is above or below 1 sq in). I can see situations where the I/O count of a SX52 is needed but the protoboard is too large of a form factor for the application.

    Paul,

    The SX52 Con Carne was discontinued. We were trying to sell it at nearly $59 for whatever reason. I don't even remember our logic - but it was before we were properly motivated by Ubicom to sell the chips. Combined with low-volume manufacturing something like the SX52 Con Carne wouldn't stand a chance. This time we'll do

    I'll get the SX52 Con Carne Gerber files and post them here so you can "have at it" with the prototype services. Not a problem for us. Glad to see you using the chip.

    Sincerely,

    Ken Gracey
