How to use the AEKD-USBTYPEC1 USB Power Delivery evaluation kit
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.
Evaluation kit overview
The AEKD-USBTYPEC1 kit consists of:
• An AEK-USB-2TYPEC1 dual-port USB Type-C interface board.
• An SPC58EC-DISP discovery board hosting a SPC58EC80E5 Chorus line 4 MB flash memory, 32-bit automotive microcontroller.
• A 1-Amp 12-Volt power supply for the SPC58EC-DISP board.
• A mini-B USB to USB Type-A cable to connect the MCU programmer.
• A USB Type-C to USB Type-C cable (not electronically marked).
• The STSW-USB2TYPEC1 flash image firmware and the related software package.
The AEK-USB-2TYPEC1 interface board hosts a pair of STUSB1702Y automotive grade USB Type-C controllers; one for each USB Type-C port. The board contains a dual Transil™ array ESDA25LY and very low capacitance USBLC6-2SC6Y devices for ESD protection. The status of the ports is signaled on the board through a set of LEDs for each port. The board includes about 20 test points.
The main devices on the board are the STUSB1702Y USB Type-C controller with Tx/Rx line driver and bi-phase marked coding (BMC), and the physical layer (PHY) protocol for USB Power Delivery stack.
The AEKD-USBTYPEC1 kit supports a 5 V, 500 mA PDO based on the electrical characteristics of the SPC58EC-DISP. To extend the range of PDOs, you can add an external power board, not included in the kit.
The software package contains the following elements:
• The firmware for the SPC58EC-DISP discovery board (already pre-loaded on the board).
• A complex driver for the STUSB1702Y USB Type-C controller.
• An SPC5-STUDIO library plugin with the USB Power Delivery software stack.
• A demo application with predefined 5 V 500 mA PDO.
The standard USB Type-C cable provided in the kit is not electronically marked. It is not suitable for currents above 3 A and does not support USB 3.1 Gen1 or Gen2 signaling.
The USB Power Delivery Consumer role device may be a compatible mobile phone or a tablet accepting a 5 V, 500 mA PDO. You can add an external Power Board to increase the range of available PDOs. Alternatively, you can use the P-NUCLEO-USB002 demo kit as a consumer device.
