Product details
Overview
AEKD-USBTYPEC1 from STMicroelectronics is an automotive-grade USB Type-C™ and USB Power Delivery (USB-PD) evaluation kit comprising a dual-port USB function board (AEK-USB-2TYPEC1) and an SPC58EC-DISP Chorus discovery board. It implements a full USB-PD protocol stack on the ASIL-B qualified 32-bit Power Architecture® SPC58 microcontroller, supports 5 V/500 mA PDO by default, includes pre-loaded STSW-USB2TYPEC1 firmware, and enables dynamic power role negotiation with external USB-C devices.
For engineers reviewing the AEKD-USBTYPEC1 datasheet, AEKD-USBTYPEC1 pinout, AEKD-USBTYPEC1 application, or AEKD-USBTYPEC1 equivalent, this kit delivers validated hardware-software integration for automotive USB-PD Provider functionality, AutoDevKit-compatible expansion, SPI/I²C-controlled STUSB1702 controllers, and configurable multi-PDO support via external power boards - all with traceable RoHS-compliant automotive components.
Technical Context
The kit centers on two STUSB1702 automotive-grade USB Type-C controllers - each handling BMC encoding/decoding, physical layer clock recovery, and PD policy engine execution - interfaced to the SPC58EC-DISP board via I²C for configuration and SPI for real-time message exchange. The SPC58 MCU runs the USB-PD stack, manages port state machines, and drives GPIOs to control external power boards.
Hardware architecture separates roles: the AEK-USB-2TYPEC1 board hosts ESD protection (USBLC6-2SC6Y, ESDA25LY), load switches (STD28P3L), and dual Type-C connectors with LED status indicators; the SPC58EC-DISP provides CAN FD, Ethernet, FlexRay, LIN, and a 4×37-pin I/O header mapped to configurable peripherals via SPC5 Studio.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Kit Composition | Dual-board system: AEK-USB-2TYPEC1 function board + SPC58EC-DISP discovery board |
| USB-PD Controller | Two STUSB1702 automotive-grade controllers (ASIL-B), each with integrated TX/RX line driver and BMC physical layer |
| Default PDO | 5 V / 500 mA available without external power board; higher PDOs require compatible external power board |
| Firmware | Pre-loaded STSW-USB2TYPEC1 USB-PD stack; supports Port 0 (always enabled) and configurable Port 1 |
| Interface Protocols | I²C for STUSB1702 configuration; SPI for PD message transport; GPIO-driven voltage selection logic for external power boards |
| ESD Protection | USBLC6-2SC6Y (low-capacitance differential-line protection) + ESDA25LY (dual Transil™ array) per port |
| AutoDevKit Support | 4×20 female connector on AEK-USB-2TYPEC1 mates to pins 18–37 of SPC58EC-DISP's 4×37 header; enables plug-and-play function board stacking |

FAQ
What is the role of the STUSB1702 in this kit?
The STUSB1702 serves as the dedicated USB Type-C physical layer and policy engine controller on each port. It handles BMC encoding/decoding, CRC generation/verification, packet framing, and CC line monitoring - offloading these time-critical USB-PD link-layer tasks from the SPC58 MCU while communicating configuration and status over I²C and PD messages over SPI.
Can AEKD-USBTYPEC1 act as a USB-PD Consumer?
No - the kit is configured exclusively as a USB-PD Provider. The SPC58 firmware and STUSB1702 setup support only Source Capabilities advertisement and contract acceptance. To simulate a Consumer, ST recommends using the separate P-NUCLEO-USB001 or P-NUCLEO-USB002 evaluation kits, not the AEKD-USBTYPEC1 hardware itself.
Is the included USB-C cable electronically marked?
No - the kit includes a non-electronically marked USB Type-C to Type-C cable rated only for ≤3 A and lacking e-marker IC support. It does not support USB 3.1 Gen1/Gen2 data rates or higher-current PD profiles; use of certified e-marked cables is required for >3 A operation or full USB 3.x functionality.
How is power profile switching implemented with an external power board?
When an external power board is connected, the SPC58 MCU configures output voltage by driving three GPIO pins (Port_sig1–3) according to a user-defined logic table - e.g., 5 V = L/L/L, 9 V = H/L/L, 15 V = H/H/L, 20 V = H/H/H. This mapping is compiled into the STSW-USB2TYPEC1 firmware and executed during PD contract acceptance.
