The TDA9381PS/… chip is a video processor from a TV with full video signal processing with a built-in microcontroller.This microcontroller is an analogue of the MK 80c51 and has a permanent memory of up to 128 Kbytes.This processor has a program for a specific TV, so when replacing the processor, this should be taken into account.
Next to the processor, on the TV boards, a memory chip for 8 pins of type 24c08 is installed and it remembers volume settings, channels, etc. working together with tda9381ps.The block diagram of the processor shows that there is also a teletext function

In the same TV there is a choice in the menu, and among other things there is a video game called Clickomania.This game and other settings are stitched into the processor
