Hi,

trying to find a datasheet/pinout for this chip. It's on the display/keypad unit of a stove. All the lower pins on the picture go to a keypad but I couldn't tell how they are connected to it, it's a sealed keypad.

On the chip it says:

NEC Japan
51A1010V38
0217KP009
A69

Thanks for any ideas!

 

Looks like a Microcontroller. Stock numbers replaced with a customer-specific (project specific) part number because it was pre-programmed at the factory with customer's firmware.

 

51 could be for 8051 compatible
V38 is the revision
0217 is the datecode - 2002 week 17

 

Agreed, looks like a 8051 micro.
