Hi Emre,

From my understanding, you want to design LPC1549 Minimum System. Is that correct?

If so, I suggest you refer our schematic of OM13056 LPCXpresso_v2 demo board.

https://www.nxp.com/downloads/en/schematics/LPC1549_LPCXpresso_v2_schem_Rev_C.pdf

Your design needs to include:

1. LPC1549 power supply/ground, reset circuit

2. if external clock needed, you need include external osc circuit

3. SWD interface for debug

4. ISP0, ISP1 for boot

Please note, the demo board schematic includes built in Link2 debug probe. customer board usually doean't need it, external debug probe is used instead. I suggest you get a LPC-Link2 debug probe for it.

Have a great day,
Jun Zhang
