Programmer for Sanyo LC87F5NC8A Microcontroller
The datasheet is available via Google. Page 4 has lists part numbers for Flash ROM programmers that can program the chip.

Here's one company that makes them: http://www.j-fsg.co.jp/en/index.html

They don't appear to sell the exact models listed in the datasheet, but the AF9709C looks like it might do the job. I bet it's expensive, but you might be able to find out how it operates it, and then emulate it with something cheaper.
