I have a toy that simply consists of a button which plays a variety of phrases when activated. My intention is to replace the sounds with my own. However, I have been unable to identify the chip and therefore cannot interface with it.
Here is a picture and schematic of the board, developed using a multimeter in continuity mode.
Here is a closeup of the chip.
I believe the markings are as follows:
There is also a "triforce" logo, for a company which I have not identified yet.
Pins 1 and 8 are particularly interesting, as they are not connected to anything. I assume they were used to program the chip, but am not able to identify a protocol if any exists.
It would be appreciated if anyone can locate a datasheet. I would also be happy with advice on identifying the function of the unconnected pins.
