Sharing my decryption of schematic of a broken toy cat

[NightMoth]

Hello

Here I’m sharing my decryption of schematic of a broken toy cat.
Just for documenting. Also somebody may be curious about circuity of this type of toys.



It is a toy cat that blinks its eyes, wags its tail and makes “cat sounds” (mew, purring etc.) when you touch it and closes its eyes and makes “snoring” sounds when you put it on its back.

Also this toy has “voice repeating” mode, and I discovered this mode only after its disassembling and schematic decryption.
I never even knew this mode was available! it looks like this toy was already broken when I bought it...

The failure was that the toy stopped responding to touch.

According to my understanding, failed module is the NY9T004A-008a Touch Key controller, all other modules works as expected (even without datasheet for AB23BP1W98, all its functions seems very clear).
Circuit board still can be used as pulse generator or as voice repeating toy.
