Basic Design Suggestions

fatihozen — Fri, 17 Jul 2020 14:39:41 GMT

Hi,

I will make my own custom board with LPC832. I will upload firmware via ISP. I will use an UART and there will be 6 pins as GPIO. I have no experience about design, Could sbd help me about it ? I mean suggestions about necessary capacitors, resistor and filters if needed. I will use internal oscillator. What will happen to unused pins, What about Reset and Vrefp,Vrefn pins ? Is there any reference schematic ? I see LPC845MAX Ev Board's documents, is it also enough for LPC832 ?

Hi fatihozen,

Hope you are doing well. There is no Development Board for LPC803, but from LPC800 series we have the boards for LPC812 and LPC824. The Schematics are in the Design Resources section. You can use them as a reference for your design.

And regarding the unused pins, you can refer to section 14.4 of the Data Sheet (Termination of unused pins).

Hope this helps. If you have any question please let me know.

Best Regards,

Ricardo
