I just bought this toy called fridgezoo. It's a small plastic animal that you put in the fridge. It has a light sensor and a button. As soon as there is light, it plays a sound, and when you press the button it plays another sound.
I figured that it may be possible to hack this thing by dumping memory, identify and replace sound content and flash it back onto the device.
There is only a single SOIC-14 chip inside the device, labelled with
There is not much else on the board, just some passives. The chip must contain everything (Storage, amplifier, analog part for light sensor) as there is no other chip on the board.
The thing works with 3 LR44 batteries (so 4.5V).
Do you know how to source some more information about that chip? What kind of interface (if any) would one expect from such a chip? JTAG?
