Full part # on the chip is ST9058C6/KC

Chip is dated 1997 (used till today) and it's in PLCC-84 package.

It probably has mask ROM and RAM - no EEPROM.

I would appreciate any info on similar processors. :D

Here is the image. Isn't it odd, that no one at official ST site

knows of it? I would imagine, it's a pre-ST90158 product. Please, any info! Any info on pinout?
