Q: Where can I find a list of chips supported by B&K programmers?

A: Due to the mass numbers of chips available in the market, the number of chips our programmers support, and the rapid growth of newer chips in the market and newer chips we support, we do not have a printable list available.  However, users can download the latest PG4UW software from our website that is used in conjunction with our programmers to search and find the chips that are compatible for either writing, reading, or both writing and reading.  To do this, follow the below instructions:

What you need before proceeding:
- Chip model numbers you plan to program
- The chip packaging (i.e. PLCC, SOIC, TSOP..etc.)
- Manufacturer of the chip
  1. Download the latest version of PG4UW software from our website (free download) here:
  2. Unzip, and follow installer instructions to install the software onto your PC.
  3. Run the PG4UW software by double-clicking the icon shown on your desktop. (Note:  If you had selected multi programming during the installation process, you will have 2 software installed.  One is called PG4UW, and the other is PG4UWMC.  DO NOT run PG4UWMC unless you are using a gang programmer (model 859 (discontinued)) or if you have multiple models of 866B that you want to connect for gang programming.
  4. At start up, the software will have an opened window asking for selecting a programming and port to connect to.  At the bottom, there is a "DEMO" button.  Click it.
  5. Now the program will run in demo mode.  You will NOT need a programmer to run this mode.
  6. Click on the "Select" button at one of the top menu icons.
  7. Here, you will find an entire listing of all the currently supported chips by our programmers.
  8. To find the chip you want to program and verify its compatibility, use the search box near the bottom of the programmer and type in the chip model.
  9. The list will automatically be filtered to match your search entry.
  10. Note that sometimes, you do not need to enter the entire chip model as a lot of chips of the same kind have variations in the characters toward the end of the name that specifies chip packaging and other attributes to that chip.  To determine how much you need to enter, just keep typing your chip model you have referenced with you until you see nothing on the list, then go back one character to find the narrowest search listing.
  11. From the listing, you may see several entries of the same chip you have, with a [ ] next to it, encapsulated with some alphanumeric characters.  Those generally refer to the packaging of that chip that programmers can program.
  12. Select the chip with the packaging that matches the one you have.  Then, at the bottom left corner of this same window, there is a button for "chip info".  Click this, and it will provide you a window with a few tabs with detailed information of the particular chip you selected.
  13. The first page will provide you list of programmers that support programming the selected chip.  Use this to determine which programmer you may need.
  14. The next tab gives you the chip dimension information.  The last tab gives you the descriptions of the coded model number in the chip name.  Here, you can find out what each of the characters in the model name represent, as well as in some cases, help you determine the chip packaging you have and other attributes that are specific to your chip.  If you don't know your chip packaging, this is one way to find out what you have.  Then, you can use it to match with one on the search list.

If the chip you have is not found on the listing, then it is currently not supported by our programmer.  As we often have updates to our software to add additional support for more and newer chips, please check back often for updates at
