I am designing my own carrier board for a robotics project. It will include an onboard BS2P-40. I know that the chip(2P40 Interpreter Chip) is a surface mount chip. This shound not be a problem
for one board. My question is. What is the dementional specs on this chip(package type, pin spacing, ect.)?
Any help would be great.

    Good luck!· Will you be using ExpressPCB or something else?· Just curious...

    yes, I almost have it finish, but was held up. I could not find the data sheet for th sx chip. There iis no link to it from Basic Stamp OEM components section.

    Thanks

    Where did you get an SX48 part for it?

    I don"t have the chip yet. Will purchase it when I have the board completed.
    Here is the link.

    No I meant where did you get a part for ExpressPCB?· The 2 I saw floating around the Forums didn't look correct.· The way I came to that 'conclusion' was that I placed an SX52 part down and tried to place the SX48 parts inside of it, and the size didn't look correct when compared to a protoboard we carry that has both sets of pads.· I guess it just didn't look right and our engineers use a totally different package so I can't import their part (PCB).

    What do you mean? The chip I will be using is a SX48BD/TQ not a SX52.
    but I needed the data sheet so I cound make the pad layout. Here is a .pcb
    file of the pad layout for the SX48BD/TQ. let me know if it looks right for the
    chip.

    I guess it looks alright, where did you get this part from?

    I made it using the data sheet. Just in case you did not know. You can make custom parts using ExpressPCB. If you read throught the help file. It will tell you how to make custom parts. So next time run need a part and its not in the defalt parts. You can make it from scratch.

    If you open that part up in ExpressPCB. Select the part. Go up to the menu and click "Component". You will see "Save Custom Component". When you click that it will ask for a name. then click ok and you will have that part. If you did not know that already.

    Actually, I have quite a large library of parts I made in ExpressPCB, including many custom one-of-a-kind parts for prototypes, but there was no comparable SX48 part and I never really tried with it.· On through-hole parts I simple place non-standard parts onto a wire-wrap board and measure the hole spacing, outside diameter, etc.· I will attach a part I made where no comparable part existed, but I got it from eBay at the following link.

    That's a nice display. I think I'm going to get one or two.

    thanks

    Yeah, it looks like it has potential.· I haven't used it yet, but as you can see from the PCB Part I created, I needed a rough idea of how much space it takes up on a board and also have my connections.· It's a little crude, but it works.· The measurements should be right on with a little overhead.

    Do you know of any good drivers that would work with this display and a basic stamp.

    Actually I plan on using a MAX7219 for the 7-Segment section of the display and either an LM3914 or a 74HC595 for the Bar Graph section.· Depends on how I use it.· I bought like 5 of the displays to try out.

    Thanks Again
