Hi,
sorry my english, and my newbie questions please...
we still having a problem with one car painel, and have a lot of this comming to me to fix burning problems...
in this eletronic have one D78F0828A chip, and it is really hard to find documentations and tools,the support of renessas tell me it is obsolete and all tools too...
but we really need or try read this (if is possible) and use the software to program a new of this....
or change this for a new model and make my own program to do all functions work again.
the software have many interactions but by my experience with this nothing exceptional, one LCD (8bits + controllers) and the pwm controls and digital/frequence inputs
if anyone should help me to start with renessas mcu and show, if have, local with pin2pin compatible devices we will be very tankful
sorry for distur comunity
and thank you for your time
Hi Reinaldo!
Well, the 78K0 has no command for reading the internal memory, so, even you have access to a good MCU and the tools, you will not be able to read it.
The replacement for the 78K0 would be a RL78, on the case of the item you are using, a RL78/D1Ahttps://www.renesas.com/us/en/products/microcontrollers-microprocessors/rl78-low-power-8-16-bit-mcus/rl78d1a-microcontrollers-automotive-low-end-instrument-clusters
But you need to find the closest one and make an adaptor, as it is not a pin to pin replacement.
To start with the RL78, all you need is a development board from the MCU you want to try, install the e2studio and start your project!

You need a MyRenesas account to download the tool.
