Where to find IS61LV25616AL-10TL schematic

#1 Post by SparkyNZ » 05 Sep 2022, 10:55

Hi. I am new to DipTrace (still using the demo) and I am trying to find a schematic (CAD model???) for a IS61LV25616AL-10TL device. SnapEDA don't appear to have one. It is a TSOP-2-44 IC.

Can somebody please help me find a schematic for this? I did find a ZIP archive somewhere that claimed to have a DipTrace schematic but it just contained a .asc file that could not be imported into DipTrace.

At the very least, a TSOP-2-44 schematic/footprint combo would be useful. I don't mind labeling all of the pins manually but I am also worried about getting the wrong size footprint and messing up a PCB order.

I'm just a hobbyist/dabbler when it comes to electronics, so please excuse my ignorance or lack of knowledge.

Symbol, footprint and 3D part
That's using the ECAD zip package right and the Library Loader? I tried that yesterday and it wouldn't load. From memory it wanted a .ASC file and there wasn't one. You're supposed to load it into DipTrace with the 3rd option on the main menu - "Component Editor" I think it is, and then Import?

If you like adventures, make your own by inserting the standard DipTrace component named "R1RP0416DSB-0PI#D0" into one of your user libraries. That will get you close to what you need because it also sports a similar 44-pin TSOP-2 pattern and 3D model. Once it is in your user component library, make the following changes...
* Name: IS61LV25616AL-10TL
* Manufacturer: ISSI
* Datasheet: (link it to your new datasheet)
* Unique Name: (located in Additional Fields)
* I/O pin names (they are sequenced 1 step higher than desired)
* "VSS" pin names to "GND"
* "VCC" pin names to "VDD"
* "CS#" pin name to "~CE"
* delete the suffix "#" found in any other pin name and insert the prefix "~" instead (place a tilde character in front of the pin name)

Thank you! I will make some time this weekend to give it a try. My biggest concern was getting the wrong size footprint and having to throw a load of PCBs (and money) into the rubbish bin. I have an FPGA "daughterboard" with 2 old through-hole DIP memory chips on it and I'm wanting to replace the older (slower) chips with these new ones. So hopefully this will help!

Thanks Tom - this has been succesful!
