How to use the AEKD-USBTYPEC1 USB Power Delivery evaluation kit
Introduction
The USB Power Delivery evaluation kit is designed to help you evaluate the functions of the USB Power Delivery protocol stack
implemented on the
SPC58EC80E5
Chorus line of 32-bit automotive microcontrollers based on Power Architecture®
technology, with 4 MB of flash memory.
You can also use the AEKD-USBTYPEC1 to prototype USB Power Delivery solutions to power compatible consumer devices
via the USB Type-C™ ports.
