LPC4353JBD208 question

[uzunov16]

Hello, I'm new in fixing electronics. I'm trying to fix my ploter PCB and i cheked with multimeter the capacitors. Every capacitor around the LPC4353JBD208 seems to be shorted. Does that means the MCU is shorted and i need to replace it?

Thank you!

I removed the MCU and now the capacitors are not shorted. That means i need new MCU?

[uzunov16]

Do i need a software to program the MCU after the replacement?

Hi,

The LPC4353 has on-chip flash, I suppose that you have to program your application code to the flash.

If you have the source code project, you can use keil, IAR or MCUXPresso tools to download the code.

If you has the *.bin or S_record file, you can use FlashMagic tools to download the code in ISP mode.

Hope it can help you

Hi,

Okay, I suppose the MCU has broken down, you need a new one.

Hi,

I suppose that the VDD and GND pins are shorted either on board or inside silicon. Pls remove the LPC4353 from board and check if the shorting happens or not.

Hope it can help you
