We are trying to create our own PCB using the core ICs of Teensy 4.1. Ideally, we would like to add the ethernet jack etc all in one PCB instead of plugging it using smaller boards. I would like to know the minimum functionality needed to power up microcontroller and connect it to the teensy IDE. Here's what I am tracking
I need microcontroller, MLK02 bootloader chip, 24MHZ clock, USB port and the functionality to give 5V power, 3.3V voltage regulator and the caps and the resistors needed. Do I need a separate 1.2V regulator or is 1.2V provided within the microcontroller itself. Could you explain DCDC_LP pin? Do I need to connect it to VDD_SOC_IN pins to give 1.2V?
