LPC2194 microcontroller replacement

Hi everyone,

I am looking forward to start a new embedded system proyect and I was thinking about LPC microcontrollers.

I just saw that the LPC2194 microcontroller is not recommended for new designs anymore but I didn't find any suggestion on which microcontroller to use instead. I would need something with similar features of Flash/RAM size, CPU frequency and peripherals.

If anyone could suggest some options of microcontrollers to replace LPC2194, I would be really grateful.

Thanks in advance.

There is not direct replacement for the LPC2000 family devices (ARM A7 ) the new devices use ARM Cortex M. Depending you final application you can check the LPC546xx family (ARM M4)

Or also check the LPC55 family

Please let me know if you need more information or if you have more questions
