I am currently making a PCB that will contain the KL03 microcontroller. I need to make sure that I wire this part properly. Can some one help to verify if all the pins and components are correct to program:
Supply:
VDD
VSS
To program Kl03:
1.LPUART0_RX
2.LPUART0_TX
3.SWD_CLK
4.RESET_b
5.SWD_DIO
6.NMI_b
Components needed:
1. SWD_DIO add 10K external pullup resistor
2. NMI pin add 4.7K to 10k external pullup resistor
3. Reset_b pin add 4.7K to 10k external pullup resistor, and a 0.1uf capacitor to ground.
4. SWD_CLK don't need to add external resistor.
5.VDD 1uF close to MCU.
Anything else I might be missing?
Many thanks in advance..
Hi ZN Sal,
You also create the same question in the official website(sale force), and I already reply you!
Thank you for your interest in NXP Kinetis product, I would like to provide service for you!
Your mentioned item is correct!
About the KL03 smallest system design, you can refer to the FRDM-KL03 schematic:
http://www.nxp.com/assets/downloads/data/en/printed-circuit-boards/FRDM-KL03Z.zip
1. Supply
VDD, VSS
Power supply bypass capacitors must be placed close to the MCU supply pins.
2. Program KL03
(1) SWD interface
SWD_CLK: don't need the external circuit
SWD_DIO: Add 4.7K to 10K external pullup resistor
Reset_b:add 4.7K to 10k external pullup resistor, and a 0.1uf capacitor to ground.
GND, vdd
(2) ROM BOOTLOADER
If you want to use the UART bootloader, please use :
PTB1: LPUART0_TX
PTB2: LPUART0_RX
3. NMI need external 4.7K to 10k external pullup resistor
4. More detail about PCB routing, please refer to Kinetis L Peripheral Module Quick Reference.pdf:

Wish it helps you!
Have a great day,
Kerry
