We are creating a board device by using LPC1114FN28/102.

It worked good at in developing process. This device output NTSC Color Signal by GPIO.

 

Now, we have changed MCU to LPC1114FHN33/333 from LPC1114FN28/102.

It got mixed with noise. Same circuit, same xtal, same board. It was changed only MCU on socket.

 

We want to remove the noise. What is difference of LPC1114FN28/102 and LPC1114FHN33/333? Is the frequency characteristic of LPC1114FN28/102 and LPC1114FHN33/333 different on GPIO?

 

Please help me, thank you.
